Should extended disability be an exclusion criterion for tertiary rehabilitation? Socioeconomic outcomes of early versus late functional restoration in compensation spinal disorders.

STUDY DESIGN: A prospective cohort design with two groups of patients representing short-term or long-term disability (n = 497) who were selected from a larger cohort (n = 938) of consecutively treated spinal disorder patients with chronic compensation injuries. OBJECTIVES: To prospectively evaluate the impact of length of spinal disability on socioeconomic outcomes of medically directed rehabilitation. SUMMARY OF BACKGROUND DATA: Despite an increasing tendency of managed care organizations to limit rehabilitation services for disabled workers with chronic spinal disorders, there has been a surprising lack of prospective research evaluating the impact of length of disability on objective socioeconomic treatment outcomes. Although only approximately 10% of all patients with spinal disorders are disabled beyond 4 months, they account for nearly 80% of all workers' compensation expenditures. Little is known about whether relatively early intervention improves outcomes after chronicity has been established or whether any predictors distinguish between these groups. METHODS: Two comparison groups of functional restoration tertiary treatment graduates were identified from the same community referral pool. The "long-term disabled" group involved a minimum of 18 months of disability (n = 252). This group was compared with a "short-term disabled" group (n = 245), no more than 8 months since injury, but chronic based on a minimum of 4 months after injury. The long-term disabled group showed significantly higher rates of pretreatment surgery than the short-term disabled group (P < 0.001). All patients were evaluated prospectively with specific physical, psychological, and occupational measurements. They also underwent a structured interview 1 year after treatment evaluating work status, health care use, and recurrent injury. RESULTS: The short-term disabled group showed statistically higher return to work (P < 0.001) and work retention (P < 0.05) relative to the long-term disabled group. However, health care use and recurrent lost time injury claims were low in both groups and did not differ significantly. No predictors of outcome were found among the prospectively collected physical performance or psychosocial variables. CONCLUSIONS: This study suggests that early tertiary nonoperative care, once patients with chronic spinal disorders are identified as having potentially high-cost chronic pain and disability, is efficacious in achieving goals of better work return and work retention. Such early rehabilitation may also prevent significant indemnity expense, as well as some late surgical interventions sought by progressively more desperate patients. However, individuals with long-term disability achieve respectable work return and retention rates, while faring no worse on other socioeconomic outcomes that represent major "cost drivers" to the workers' compensation system. Early intervention is not a panacea or a necessary condition for the successful rehabilitation of workers with disabling chronic spinal disorders.

Recurrent disabling work-related spinal disorders after prior injury claims in a chronic low back pain population.

BACKGROUND CONTEXT: Multiple compensation injury claims are an understudied phenomenon in the chronic back pain and occupational injury literature. Assumptions about poor treatment outcomes for patients presenting with prior injury can lead to denial of treatment, even though these assumptions have not been empirically addressed. Functional restoration has been demonstrated to be an effective rehabilitation treatment for disabling, work-related chronic back pain, although its' relative utility with recurrent injury (RI) patients has not been previously evaluated. PURPOSE: To assess demographic, psychosocial and work history/adjustment differences between the two groups, and to investigate whether patients with recurrent work-related spinal injury claims benefit from functional restoration treatment at a level equivalent to patients with nonrecurrent injuries. STUDY DESIGN/SETTING: A prospective cohort design assessing characteristics and outcomes of patients with recurrent work-related spinal disorders, compared with a group of patients without prior work-related spine injury claims, all treated with the same interdisciplinary rehabilitation protocol. PATIENT SAMPLE: A cohort of consecutively treated functional restoration rehabilitation patients (n=395) divided into two groups based on a history of prior work-related injury. The RI (n=172) group had at least one prior work-related injury claim (with or without lost time), whereas the nonrecurrent injury (NRI; n=223) group did not. OUTCOME MEASURES: The RI and NRI groups were assessed for prospectively collected demographic, psychosocial and work history/adjustment data. A structured clinical interview addressing socioeconomic outcomes and assessing work return, health utilization, recurrent injury and case closure was administered 1 year after discharge from the treatment program. METHODS: Consecutive patients from a regional referral center for tertiary rehabilitation treatment of chronic work-related musculoskeletal injuries were evaluated with a comprehensive biopsychosocial assessment protocol at pretreatment and posttreatment. Moreover, at 1 year after completing the program, a structural telephone interview was conducted that assessed health and socioeconomic outcomes. RESULTS: For the 1-year socioeconomic outcomes (such as posttreatment injury), the RI patients responded to rehabilitation at a level equivalent to the NRI patients. Demographic analyses revealed that RI patients, relative to NRI patients, were older, more represented by the dominant culture, had more education, had a shorter length of disability, had less severe types of injuries, had a greater rate of non-work-related health conditions, received higher disability payments, and had slightly greater job demand. The RI group also had a greater rate of pre-injury Axis I psychiatric disorders, particularly substance abuse/dependence disorders, than the NRI group. In addition, the RI group had greater job stability than the NRI group. CONCLUSIONS: The results of this study indicate that, although patients with recurrent injuries evidence differences in demographic, psychosocial and work history/adjustment differences when compared with patients with nonrecurrent injuries, their 1-year outcomes after tertiary, medically directed rehabilitation are identical. Both groups demonstrate very low rates of further work-related injuries through the first posttreatment year. Patients with recurrent injuries appear to develop skills in dealing with the workers' compensation system with a familiarity not seen in NRI patients. Of course, these results will need to be replicated in other settings to determine whether they can be generalized to the entire workers' compensation population.

Are gender, marital status or parenthood risk factors for outcome of treatment for chronic disabling spinal disorders?

Recent clinical research has suggested that single working mothers may differ in their response to health treatment and outcomes, relative to their married female or male counterparts. The present study explored, on an a priori basis, the existence and extent of differences in chronic pain rehabilitation outcomes of pain report, return-to-work and future health utilization for single working mothers, relative to other patients. A cohort of 1,679 consecutive chronically disabled work related spinal disorder (CDWRSD) patients were placed into one of eight groups as a function of gender, marital status (single/married), and parenthood (with/without children). All patients completed an assessment battery measuring psychosocial variables at pre- and post-treatment, and a structured clinical interview evaluating socioeconomic outcomes at 1 year following completion of a 5-7 week functional restoration program. Results revealed that single females with children differed from all other groups in racial representation, with 57.1% of these individuals being African American, widely disparate from the prevailing local ethnicity. Single females and males with children were represented by a higher incidence of cervical injuries (25.0% and 26.7%, respectively) than all other groups (5.4-16.6%, p < .001). Contrary to expectation, the 8 groups did not differ significantly in program completion rate, work return, work retention, health utilization, recurrent injury or case settlement rates at one-year follow-up. The single females with children group did display greater levels of depression pre-treatment compared to the other groups. However, at post-treatment, these differences no longer existed. This investigation is one of the first to examine if the combination of gender and parenthood distinguishes significantly among CDWRSD patients. Overall, contrary to expectation, the single mothers did not show any significant differences in CDWRSD outcome at one-year post-rehab follow-up, and the single mothers and fathers showed no differences in depression or pain severity post-treatment. Thus, in spite of the societal belief to the contrary, it seems that single parent patients can show similar chronic pain rehabilitation outcomes, relative to other CDWRSD patients, after a prescribed course of tertiary functional restoration rehabilitation.

Long-term physical functioning and psychosocial adjustment in survivors of sudden cardiac death.

OBJECTIVE: To identify and describe a range of functional health outcomes in a sample of sudden cardiac death survivors. DESIGN: Cross-sectional survey. SETTING: Northern California tertiary medical center. SUBJECTS: Sixty-one sudden cardiac death survivors at least 6 months but not more than 4 years after cardiac arrest. Subjects were excluded if they had uncontrolled congestive heart failure, unstable angina, other debilitating cardiac or concomitant illness, or evident cognitive deficits. METHODS: Chart reviews, patient interviews, and a standardized questionnaire. RESULTS: Survivors reported significantly poorer physical functioning than normal subjects (p < 0.001), although none were limited in self-care. Mental Health Index Scores and subscale scores for psychologic well-being were within established norms. However, mean scores for the psychologic distress subscale were elevated (p < 0.001). Initial work return was 72%. Of the 37 (61%) survivors who were sexually active before their arrests, 78% resumed coitus. Twenty-five survivors reported mild to moderately severe impairments in memory or other cognitive skills. Poor physical functioning was associated with illness severity, change in work status, and increased anxiety. Psychologic distress was associated with change in work status and poor physical functioning, but not illness severity. CONCLUSIONS: Despite significant decreases in physical functioning and reports of mild to moderately severe cognitive impairments, only a minority of sudden cardiac death survivors are severely psychologically distressed. Illness severity is a strong predictor of physical functioning, but its contribution to psychologic distress is indirect, acting largely through the aegis of poor physical functioning and loss of prearrest work status.

Patients' satisfaction with provided care/information and expectations on clinical outcome after lumbar disc herniation surgery.

STUDY DESIGN: A prospective study of patients undergoing lumbar disc herniation surgery. OBJECTIVES: To assess patients' satisfaction with care/preoperative information, if expectations on surgical results and ability to return to work are related to baseline characteristics, and/or can predict self-reported outcome. Self-reported outcome was compared with objective outcome. SUMMARY OF BACKGROUND DATA: Patients' expectations on treatment results have been discussed as a predictive factor for postoperative outcome and satisfaction demonstrated to be directly related to patient expectations. METHODS: The study includes 148 patients, 46% women, mean age 40 (range 18-66). Before and 2 years after surgery, questionnaires about given information/care, expected/present work ability, and expectations on/obtained improvement of physical functions/symptoms (leg and back pain, sensibility, and muscle function) were filled in. The visual analog scale leg pain, Zung Depression Scale, and Oswestry Disability Index were used as baseline characteristics. At 2-year follow-up, self-reported and objective outcome was assessed. RESULTS: Satisfaction with given information/care were reported by 46% and 82%, respectively. Zung Depression Scale related to expectations on leg pain recovery (P = 0.022), work ability (P = 0.046), and satisfaction with given information (P = 0.031). Patients who expected to return (76%) and not return (24%) to work, returned in 78% and 26%, respectively (P = 0.021). A high agreement between self-reported outcome and objective outcome were found (P < 0.001). CONCLUSIONS: Patients undergoing lumbar disc herniation surgery are mostly satisfied with provided care before and after surgery, however, less satisfied with information provided. Further, patients with preoperative positive expectations on work return and realistic expectations on pain and physical recovery have a greater chance to be satisfied with the surgical results.

Effectiveness of Waddell's nonorganic signs in predicting a delayed return to regular work in patients experiencing acute occupational low back pain.

STUDY DESIGN: Consecutive case series. OBJECTIVE: To determine whether the presence of Waddell's nonorganic signs in occupational, acute low back pain patients predicts a longer time before return to unrestricted regular work. SUMMARY OF BACKGROUND DATA: Waddell's nonorganic signs identify patients with chronic low back pain with a poor prognosis; however, they have not been used as an outcome predictor in patients with occupational, acute low back pain. METHODS: Standardized histories and physical examinations, including Waddell's signs were recorded at the first clinic visit (n = 143) by a single physician who was not blinded to the study's goals or methods. Those with chronic low back pain or complicating medical conditions (n = 88) were excluded. Data from patients exhibiting the nonorganic signs were compared with those from patients without the signs for time to return to regular work without restrictions and medical resource use. RESULTS: Fifty-five patients with acute work-related low back pain were included. One or more of the nonorganic signs were seen in 14 patients (25.5%) at the first appointment. The most common signs were simulated axial loading (78.6%) and simulated rotation (71.4%). Those with any nonorganic sign required a median 58.5 days to return to regular work compared with 15.0 days for those without (P < 0.0001). Patients exhibiting any nonorganic sign compared with those without used more physical therapy (50.0% vs. 12.2%; P < 0.01) and lumbar computed axial tomography (21.4% vs. 0.0%; P = 0.01). CONCLUSIONS: Patients with acute, occupational low back pain exhibiting Waddell's nonorganic signs had a four times lengthier time for return to unrestricted, regular work and a greater use of physical therapy and lumbar computed tomographic scans.

Predictors of employment of men with HIV/AIDS: a longitudinal study.

OBJECTIVE: To identify patterns and predictors of work status and number of hours employed in a group of men with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS). METHODS: A total of 141 participants had semiannual neuropsychiatric, psychosocial, and medical assessments over a period of 30 months. These six occasions provided the basis for identifying patterns of employment (part-time, full-time, or unemployed). Those who completed neuropsychological testing, introduced at visit 4, constitute the sample used to identify predictors of number of hours employed, using multiple regression analysis with mixed procedure. RESULTS: Over 30 months, 20% were continuously employed full-time, another 9% were continuously employed part-time, and 40% were continuously unemployed. Employment status changed for 31%: 4% who worked at baseline stopped, 13% started or increased their hours, 8% decreased their hours, and 6% showed a fluctuating pattern. The major parameters consistently associated with unemployment or partial employment, in order of influence, were financial (disability benefits), psychiatric (past/current diagnosis of major depression and/or dysthymia), medical (physical limitations), cognitive (executive function), and education. In contrast, age, ethnicity, laboratory markers of HIV illness status, vocational rank, and past or current substance dependence did not predict work status. CONCLUSIONS: Overall, those who worked continued to work. However, despite improved health, most men who were unemployed at study baseline did not return to work. Structure of disability benefits, lifetime depressive disorder, physical limitations, and impairment in some areas of cognitive function each appear to represent significant barriers to work. Returning to work is evidently difficult, and clinicians may keep this in mind when recommending leaving work unless medically necessary. Specific interventions and policy changes regarding disability benefits may be needed to promote return to work for people with HIV/AIDS whose health is restored and who contemplate re-employment.

[Surgical treatment of injuries of the thoracolumbar transition--3: Follow-up examination. Results of a prospective multi-center study by the "Spinal" Study Group of the German Society of Trauma Surgery].

OBJECTIVES: Prospective, multicenter study addressing late results after operative treatment of acute thoracolumbar spinal injuries. METHODS: 682 patients (T10-L2) were included and 372 (80%) were postoperatively followed for 2 1/4 years (4-61 months). RESULTS: Comparing the initially included patients (n = 682) with the study group (n = 372), no differences were observed and results were assumed to be representative. A C-type lesion or polytrauma significantly prolonged the hospital stay. The method of operative treatment did not affect the length of the rehabilitation period. Neurological improvement was observed in 3 out of 7 patients with complete, and in 44 out of 64 (69%) with incomplete lesion. The operative method did not affect the improvement rate. The physical capacity significantly decreased. After a mean of 1/2 year of disability only 71% returned to work. 48% returned to their preoperative physical level. The mean Hannover Spine Score was 68 points (preoperative 94, p < 0.001), indicating permanent impairment of function. The angle-stable internal fixator was superior in restoration of spinal alignment and best radiological results were noted after combined stabilization. Posterior stabilization lead to high re-kyphosing. No correlations between radiologic and clinical parameters were observed. CONCLUSIONS: All treatment methods under study were appropriate for achieving comparable clinical and functional outcome. The internal fixator is superior in restoration of the spinal alignment. Best radiological outcome is achieved by combined stabilization. Merely by direct reconstruction of the anterior column the postoperative re-kyphosing is prevented and a gain in segmental angle is achieved.

[Principles of OSG arthrodesis in cases of joint infection].

A chronic empyema of the ankle joint often develops after an open fracture or surgery. In the case of the destruction of the joint due to an infection, an arthrodesis should be performed. Normally we use an external fixator with two bone-nails placed into the calcaneus and two into the tibia. The arthrodesis is distracted and Septopal is permanently implemented. At 4-6 weeks after surgery the Septopal is removed, with distraction being reduced and a cancellous bone-graft taken from the dorsal iliac crest is performed to fill the bony defect. After bone healing, the external fixator is removed and the patient mobilized in a brace. Initially, weight-bearing is limited to 10 kg but is increased gradually to full weight. The brace is used for 6-9 months; later the patient is mobilized in orthopaedic shoes. In difficult cases, also in combination with a malposition which has to be corrected or a lengthening of the lower limb, we use the Ilizarov fixator. From 1993 to 2003 we performed arthrodeses of the ankle joint due to infectious destruction in 107 cases. In 82.2%, the empyema was caused by a fracture of the ankle joint and the following treatment. In 58% of the patients, we saw associated diseases such as obesity, alcohol abuse, diabetes and malposition of the foot. In 55% we found Staphylococcus aureus. In 86%, we used the external AO-fixator, in 14% the Ilizarov fixator. The patient retained the fixator for an average of 128 days. In our study, 92.1% of the 101 patients who had completed therapy showed a good stability an average of 4.5 years after the arthrodesis. In 5% we found partial stability, while three patients had to be amputated. In 57 patients (56.4), an arthrosis of the tarsal bones was found, and 38 patients (54.3%) of the 70 patients who at the time of the arthrodesis were still working could return to work.

[Lumbar fusion in adults--dorsal or combined ventral/dorsal approach?].

A retrospective study was conducted to compare the results of posterior with combined anterior/posterior lumbar fusion in adults. Seventy-six consecutive posterior cases fused with pedicle screws and 46 combined cases were included and followed for at least 2 years. Subjective assessment was based on the Visual Analogue Scales, Waddel Disability and Impairment Score and the GBB for objective quantification of complaints. Furthermore, a thorough clinical examination was done and X-rays including flexion/ extension radiographs, were taken. Questions were asked about the occupational status as well. Pain decreased significantly more in the combined cases than in the posterior fusion cases. In one case a lesion of the common iliac vein occurred during a retroperitoneal approach. Only about half the patients working preoperatively returned to work again. In conclusion, the benefit of better pain relief after combined fusion must be regarded in relation to a higher complication rate due to a second approach.

Influence of injury severity on quality of survival after head injury.

The relationship between severity of injury [as determined by the Glasgow Coma Scale (GCS)] and the quality of survival (as determined by neuropsychological measurements and work return) were investigated in 54 conscious survivors within 16 months following head injury. While severely head injured (GCS less than or equal to 8) patients had more neuropsychological impairments in areas of intelligence, attention, memory, visuomotor speed, and motor skills than those with mild injuries (GCS greater than 8), performances after both types of injury were below normative levels in areas of learning, memory, and visuomotor speed. Unemployment increased after both severe and mild injuries, while employment status changed more frequently after severe injuries. Age had a minimal effect on neuropsychological and employment outcomes after minor head injuries (GCS greater than 13). The findings suggest that regardless of acute severity, closed head injury influences long-term quality of survival.

Review of burns caused by bitumen and the problems of its removal.

Bitumen burns are difficult to treat as the substance adheres to the skin. Twenty-four patients with such burns admitted as inpatients over a 9-year period have been reviewed. The mean size of the burn injury was 3 per cent of the total body surface area (mean full thickness burn: 1 per cent). Sixteen patients required operative treatment to achieve healing but no secondary reconstructive procedures have been performed. Twenty-two patients, who were burned at work, returned to their original employment within 2 months of injury. There was no decrease in the need for operation or decrease in the time to healing in those patients who had attempted early removal of the bitumen. Suggested principles of management are: cool the bitumen continuously with cold water until hard to dissipate the retained heat, leave the bitumen intact except around the eyes, and deroof tense blisters.

Effects of a cognitive-behavioral pain-management program.

A cognitive behavioral multidisciplinary pain management program was evaluated in two separate outcome studies; one controlled study (study I) and one study conducted on a consecutive sample with a long-term follow-up (study II). The 4-week inpatient treatment program included education sessions, goal setting, graded activity training, pacing, applied relaxation, cognitive techniques, social skills training, drug reduction methods, contingency management of pain behaviors, and planning of work return. The outcome of study I showed significant between-group differences in favor of the treatment group on measures of occupational training at 1-month follow-up, activity level in the sparetime at post-treatment and at follow-up, and decreased catastrophizing and pain behaviors at post-treatment. In study II significant improvements over time were found on measures of sick leave, pain intensity, pain interference, life control, affective distress, activity level in the sparetime, physical fitness and use of analgetics at 2-month follow-up and at 1-year follow-up. The results of the two outcome studies reported show that cognitive behavioral multidisciplinary pain management programs can successfully be applied to Swedish musculoskeletal pain patients.

Gadolinium attenuates regional stunning in the canine heart in vivo.

OBJECTIVE: Gadolinium, a lanthanide cation, ameliorates pathophysiologic features of both heart failure and cardiac arrhythmias. We have shown, in an in vitro model, that gadolinium blocks stretch-induced contractile dysfunction in both normal and stunned myocardium. The present study tested the hypothesis that gadolinium would also attenuate regional myocardial stunning in an in vivo model. METHODS: Mongrel dogs (n = 13) were subjected to regional myocardial ischemia (occlusion of the left anterior descending coronary artery) for 15 minutes, followed by reperfusion for 180 minutes. Intravenous gadolinium (500 micromol) was given to 7 dogs before ischemia; no gadolinium was given to control animals. Regional contractile function was assessed serially by means of both systolic shortening (percentage) and regional preload recruitable stroke work. RESULTS: Administration of gadolinium before ischemia had no effect on heart rate, arterial blood pressure, stroke volume, or regional contractile function. Ischemia resulted in paradoxical systolic bulging in both groups. After 180 minutes of reperfusion, systolic shortening was enhanced in gadolinium-treated animals compared with that in control animals (10.9% +/- 1.5% vs 2.4% +/- 1.7%, P =.003). Both the slope and x-axis intercept of regional preload recruitable stroke work returned to preischemic values in treated animals but remained abnormal in control animals. CONCLUSIONS: These data confirm that gadolinium attenuates regional myocardial stunning in vivo. Gadolinium may cause peripheral vasodilatation but does not appear to exert positive inotropic effects on the normal canine heart. The mechanism underlying gadolinium-mediated effects on stunned myocardium remains undefined, but this study suggests that use of gadolinium may represent a novel adjunct to current cardioprotective strategies.

Recovery following lateral medullary infarction.

Lateral medullary infarction (LMI) has a well-defined clinical syndrome and vascular pathology. The functional outcome and degree of disability of patients with LMI, however, have not been as well investigated. We followed 18 consecutive patients with LMI during inpatient stroke rehabilitation. Thirteen patients were followed after discharge from the hospital over a mean time of 1 year. The degree of disability on admission and discharge from the hospital, and at follow-up was assessed using the motor component of the Functional Independence Measurement (FIM-motor). All patients were discharged home. During inpatient rehabilitation, the functional performance of all patients improved substantially from FIM-motor 50.9 +/- 13.0 (mean +/- SD) on admission to 76.9 +/- 10.5 at discharge. Patients with lower FIM-motor scores on admission had more functional improvement from admission to discharge than those with higher FIM-motor scores on admission. Patients with disease of the posterior inferior cerebellar artery showed significantly less functional improvement than patients with disease of the vertebral artery or no identified vascular pathology in the posterior circulation. In the follow-up group, the FIM-motor scores further improved to 84.6 +/- 8.4, indicating nearly full functional independence. Eighty-five percent were totally independent with ambulation. Five of seven previously working patients returned to work. Patients with LMI have few functional deficits after completion of inpatient rehabilitation, continue to improve functionally after discharge, and often resume their previous activities.

Systematic reinforcement: academic performance of underachieving students.

The effect of contingent tangible and social reinforcement on academic performance was investigated in an experimental classroom of 25 selected underachieving students. Measures were taken of both teacher and child behavior during a baseline and two experimental treatment periods. During Treatment I, a point system with tangible backup reinforcers was combined with contingent social reinforcers dispensed by the teaching staff to assess the effects on three measures of academic performance (i.e., per cent of time at work, work output per minute, and accuracy). During Treatment II, the contingencies for the tangible reinforcers were terminated while social reinforcement was continued to see if the positive effects of Treatment I on academic performance would persist. The results show that with combined tangible and social reinforcers, students' work time, rate of output per hour, and accuracy in all activities substantially increased. After termination of the tangible reinforcers, the students maintained their high rates of output per hour and accuracy for the remaining period of the study while the total amount of time at work returned to the baseline level.

Clinical follow-up of 106 patients five years after coronary bypass surgery for angina pectoris.

One hundred and six consecutive survivors were re-examined five years after coronary bypass surgery for stable angina pectoris (88 patients) or unstable angina (18 patients). Ninety-two per cent had less symptoms than before operation, 70% were so improved that they were not restricted in daily life and 30% considered themselves free from angina. Excluding one patient, who experienced chest pain at the exercise test and three asymptomatic patients who had undergone repeat operations, only 26% were free from angina at the five-year evaluation. Patients without angina had significantly lower diastolic blood pressure than those with residual symptoms, whereas the type of angina, smoking habits, serum lipids and common risk factors did not differ significantly. Thirteen per cent were employed on admittance for surgery, 49% had been able to work after surgery and 36% of those, who did not have old-age pension or invalidity pension for non-cardiac causes, worked full-time five years after surgery. Patients with sedentary work returned more often (53%) than those with manual labour (22%) and patients with sick-leave less than six months before surgery more often (91%) than those with sick-leave more than two years (13%). Peri-operative infarction was recorded in 5% and a further 10% suffered late myocardial infarction.

Hip fusion in young adults.

Hip arthrodesis remains an option for treatment of severe arthritis in young persons resulting primarily from osteonecrosis, congenital dysplasia, and joint sepsis. The authors reviewed six patients who underwent fusions as young adults (average age: 30.8 years) with an average follow-up period of 11.7 years. Solid arthrodesis without infection was noted in all cases. Patients who worked returned to prior employment without limitation. All patients complained of symptomatic low back pain and felt ambulation was limited by ipsilateral knee pain. Five of six noted impaired sexual function; although childbearing was not affected in one case. Four of six were satisfied with the operation, but only three of six would undergo it again given the alternative of total joint arthroplasty.
