Open reduction and fixation of proximal humeral fractures and fracture-dislocations.

Open reduction and internal fixation was employed in the treatment of 25 severely displaced fractures and fracture-dislocations of the proximal humerus. Our aims were accurate reduction and stable fixation to allow early mobilisation and to achieve full functional recovery. In 15 fractures an AO T-plate was used and in 10 a bent semitubular plate was employed as a blade plate. Excellent or satisfactory results were obtained in all six patients with two-part fractures involving the surgical neck; in four of the five patients with three-part fractures involving the surgical neck and tuberosities; in nine of the 11 patients with fracture-dislocation; and in two of the three patients with split fractures of the humeral head. Overall results were good or satisfactory in 21 of the 25 cases. Unsatisfactory results were associated with rotator cuff damage.

Decreased broadband ultrasound attenuation of the calcaneus in women with fragility fracture. 85 Colles' and hip fracture cases versus 77 normal women.

The broadband ultrasound attenuation (BUA) of the right calcaneus was measured in 49 women with Colles' fracture, in 36 women with hip fracture, and in 77 normal women. All were postmenopausal, and the fractures were all of fragility type. BUA correlated with age only in the normals. BUA distinguished between the fracture cases with sensitivities of 97 percent and 70 percent and specificities of 72 percent and 92 percent at 61 dB/MHz and 51 dB/MHz, respectively. The women with hip fracture had lower BUA than those with Colles' fracture. For screening purposes, BUA below 51 dB/MHz may arouse suspicion of a fracture risk, notably if other factors such as a tendency to fall, dietary and other habits, inactive lifestyles and early menopause are present.

Epidemiology of scapular fractures. Incidence and classification of 338 fractures.

We have studied scapular fractures, with special reference to intraarticular glenoid fractures, during a 10-year period in 2 Swedish counties. There were 338 scapular fractures in 322 patients. The annual incidence was 10/10(5) inhabitants, of which 30 percent affected the glenoid cavity. Out of 100 intraarticular glenoid fractures, 55 occurred in men and 45 in women. The mean age of the women at the time of fracture (64 years) was significantly higher than the mean age of men (49 years). The most common intraarticular glenoid fracture type was the anterior chip fragment fracture which, in about two-thirds of the cases, was associated with shoulder dislocation.

Ipsilateral proximal metaphyseal and flexion supracondylar humerus fractures with an associated olecranon avulsion fracture.

An ipsilateral proximal humerus fracture, "flexion" supracondylar humerus fracture, and olecranon fracture found together is a rare event. The supracondylar fracture should be reduced and percutaneously pinned before the ipsilateral upper extremity fractures are reduced. Displaced supracondylar fractures should be pinned with crossed smooth pins. Most pediatric proximal humerus and olecranon fractures can be treated closed.

Mandibular fracture complications associated with the third molar lying in the fracture line.

A retrospective study of 622 patients (551 men and 71 women, age range 14-63 years) with 650 mandibular fractures crossing the third molar was conducted. In 183 patients (193 fracture lines) the wisdom tooth was retained or partially erupted and in 439 patients (457 fractures) the wisdom tooth in the fracture line was normally situated in the dentition. The analysis showed no statistically significant difference in the complication frequency associated with the extraction of retained or erupted wisdom teeth (12.50% and 8.37%, respectively). In treatment of fractures with retention of the wisdom tooth in the fracture line the complications with the totally erupted and normally situated third molars were more frequent than those with the unerupted third molars (20.70% vs 7.69%). The analysis of the complications according to the applied method of treatment shows that the complications in open (operative) reposition and fixation of the fragments were more frequent with unerupted (20.00%), as well as with erupted wisdom teeth (24.13%). With closed (non-operative) fracture treatment the complications were respectively 7.30% with the unerupted and 11.33% with the erupted wisdom teeth. On the basis of the obtained results conclusions are made for the practice.

Quality of life in osteoporotic patients with hip fracture and without fracture.

The aim of this study was to analyse the quality of life in osteoporotic patients with hip fracture and those without fractures. The study included postmenopausal women, 35 with hip fracture and 33 without fractures. The control group included 44 age-matched healthy women. Osteoporosis Quality of Life Questionnaire was used to assess the health-related quality of life (HRQL). Patients with hip fracture had significantly lower scores in symptoms, physical function and leisure (P < 0.05), than patients without fractures. Both groups of patients had significantly lower scores than controls in all domains except Leisure. Analysing several health and social factors that could influence HRQL, we found that bone mass in spine and femoral neck significantly correlated with HRQL. Since patients with osteoporosis usually have no symptoms before fracture, early diagnosis and the treatment of the disease are of key importance to the quality of life in these patients.

[Preoperative blood test results and type of fracture as transfusional risk factors in patients older than 65 years with trochanteric hip fracture].

OBJECTIVE: To determine the effect of risk factors for allogenic blood transfusion in surgery for trochanteric hip fractures. PATIENTS AND METHODS: A retrospective study of all the trochanteric hip fracture patients older than 65 years who underwent surgery to repair trochanteric hip fracture related to osteoporosis in 2000 and 2001 in a regional hospital. Data recorded were age; gender; type of fracture (international AO classification); level of anesthetic risk (ASA classification); hemoglobin concentration and hematocrit upon admission, on the day of surgery and 2 days later; time elapsing between admission and surgery; blood transfusion and blood product use. RESULTS: One hundred two patients (29 men and 73 women) with trochanteric hip fractures were studied. Mean (+/- SD) patient age was 82.9 +/- 8.8 years (range, 65-99 years). Upon admission, mean hemoglobin was 123 +/- 18.1 g/L (range, 56-154 g/L), hematocrit was 37% +/- 5% (range, 10%-40%). Time elapsing until surgery was 3.5 +/- 1.6 days (range, 0-8 days). Admission hemoglobin concentration was lower in patients who required transfusion (116 g/L) than in patients who did not (133 g/L) (P < 0.001). Logistical regression analysis identified only AO classification of fracture type (P < 0.05) and admission hemoglobin concentration (P < 0.001) as independent risk factors for transfusion. CONCLUSIONS: The hemoglobin level at admission and the trochanteric fracture type bear a relation to transfusion needs. These results suggest that in elderly patients we should improve hemoglobin levels and initiate blood salvage measures in order to reduce the need for allogenic blood transfusion, with its inherent risks.

[Distal radius fractures--forms of fracture and injury pattern].

Fractures at the distal end of the radius are the most frequent fractures. There are still many therapeutical problems. The success of conservative or operative treatment depends mainly on the different types of fractures. In order of compare end results and to recommend therapy, it is necessary to define different fracture types, based on practical classification. A classification of fractures at the distal end of the radius is presented, with localization and reference to the extent of injury with consideration of lesions of the radiocarpal joint and indirectly to the distal radio ulnar joint. In the period of growth five types of injuries are differentiated. In adults three main groups, depending on the involvement of the radio-carpal joint are described. These are subdivided according to dislocation. The fractures types were classified by using X-rays of cases over a period of several years. With this classification the pattern of injury of 593 fractures of the distal end to the radius, treated in 1980 in our clinic, was analysed.

[Use of a Russel-Taylor nail for stabilizing fractures of the femur. Apropos of 57 fractures with 30 computed tomographies of the rotation].

PURPOSE OF THE STUDY: A clinical and radiographical study with CT in 30 cases was undertaken in femoral fractures fixed with Russel-Taylor intramedullary nail. MATERIAL AND METHODS: In this retrospective study of 57 femoral fractures (mean follow-up 22 months), all fractures were analysed according to the classification of Wiss and Winquist-Hansen-Clawson. Fixation was performed with Russel-Taylor intramedullary mailing. Fifty fractures were classified as unstable due to the type of fracture and for its localization. Analysis of the clinical and radiographical results was performed immediately postoperatively and later by CT (30 cases). RESULTS: Clinical results showed seven cases of hip pain and limited walking capability; twenty with decreased hip mobility; twenty-one with functional impairment of the knee with limited flexion (11 cases) and/or knee sprain (15 cases). Radiographical results showed sixteen cases of leg shortening inferior to 1 cm, three between 1 and 2 cm, and one exceeded 2 cm; nine with varus angulation of 5 degrees, one with valgus angulation of 5 degrees, and seven with external rotation exceeding 10 degrees, five with internal rotation exceeding 10 degrees. Results were determined according to Thorensen's criteria. DISCUSSION: The use of Russel-Taylor intramedullary nail for the management of complex femoral fractures is discussed. Rotational deformities appeared related to the quality of reduction during surgery. Because of the stiffness of this type of nail, a smaller diameter can be used. Result analysis demonstrates that static nailing should probably be used more frequently in unstable femoral fractures.

[Femoral shaft fracture and secondary diagnosis of ipsilateral femoral neck fracture. Typical constellation or a complication of the distal femoral nail (DFN)?].

We present a case of two patients with a distal femur shaft fracture due to a high velocity trauma. Both were treated with a distal femur nail (DFN). After mobilisation a fracture of the neck of the femur was diagnosed which was not seen in the x-rays on admission. In this paper we discuss whether this is a typical constellation of ipsilateral fractures of the neck of the femur in femur shaft fractures or a complication of implantation of a DFN. Immediately after operative treatment of a femur shaft fracture specifically after high velocity trauma or in polytraumatized patients an x-ray of the hip in two plains should be made in the same narcosis. A possible fracture of the neck of the femur could be treated at same time. Post-operatively a further diagnostic should be done in case of suspicion, e.g. pain during mobilisation.

The effect of fracture and fracture fixation on ultrasonic velocity and attenuation.

Measurement of the velocity of propagation and attenuation of ultrasound (200 kHz) is believed to be a useful non-invasive technique for assessing the mechanical properties of bone. A new method for the determination of ultrasound velocity and attenuation of longitudinal waves in cortical bone was used in vivo and in situ on intact and fractured human tibiae. The measured ultrasound attenuation and velocity were found to be unaffected by the soft tissue between transducers and bone. The ultrasound velocity in vivo on control tibiae was 3614 +/- 32 m s-1 and the attenuation was 5.52 +/- 0.43 dB MHz-1 cm-1. The ultrasound velocity in fractured tibiae was considerably lower 1 week after fracture (2375 +/- 82 m s-1), but had significantly increased after 3 weeks (to 2882 +/- 90 m s-1). A higher attenuation was measured 1 week after fracture (17.81 +/- 3.91 dB MHz-1 cm-1), but it had decreased again 3 weeks after fracture (10.42 +/- 3.56 dB MHz-1 cm-1). In situ studies under well-defined conditions confirmed the in vivo results. The effects of internal plate fixation and gradually cutting through the cortex on the ultrasound velocity and attenuation were studied in situ. These results demonstrate the clinical potential of this technique for the non-invasive assessment of bone fracture healing.

Fracture healing in tibia fractures with an associated vascular injury.

BACKGROUND: Tibial fractures with an associated vascular injury are a challenging management problem for the orthopedic and vascular surgeon. The effect of a concomitant vascular injury on fracture healing has not been specifically delineated previously. METHODS: We performed a retrospective review of 29 fractures of the tibial shaft with an associated vascular injury in 28 patients. RESULTS: Overall there were 44 vessels injured (38 arterial and six venous). A total of six patients had an amputation performed; patients requiring amputation were significantly older than those without amputation. Fractures with an associated injury to the posterior tibial artery had a significantly higher nonunion rate and a greater number of weeks to union than fractures without this vascular injury. CONCLUSION: Outcomes of tibial fractures with an associated vascular injury are poorest in older patients (who are at increased risk of amputation) and those with an injury to the posterior tibial artery (who are at increased risk of delayed union and nonunion).

[Eponyms of distal radius fractures. Colles-Pouteau, Smith-Goyrand and Barton fractures and their importance in the trauma surgery patient sample].

Fractures at the distal end of the radius are quite common. So, these fractures are well known to represent consequences of industrial accidents leading to temporary unfitness for work, too. Eponym descriptions of fractures may mislead authors and readers as well if used in a non-uniform way in medical literature. Using the original articles of the first describing authors a clear distinction of eponyms concerning fractures near to the wrist joint is given. The authors of this feature report of the clinical experience in treatment and results of distal radius fractures in combination with aspects of expert opinions on these fractures.

Effect of alendronate on limited-activity days and bed-disability days caused by back pain in postmenopausal women with existing vertebral fractures. Fracture Intervention Trial Research Group.

BACKGROUND: Women with new vertebral fractures have an increased risk of back pain and functional limitation because of back pain. Alendronate sodium treatment reduces the risk of new vertebral fracture by 50% in postmenopausal women with osteoporosis. OBJECTIVE: To determine the effect of alendronate therapy on days affected by back pain in postmenopausal women with existing vertebral fractures. DESIGN: Three-year, placebo-controlled, randomized, double-blind study. SETTING: Fifteen university-based research clinics in the United States. PARTICIPANTS: A total of 2027 postmenopausal women aged 55 to 81 years with low femoral neck bone density and a preexisting vertebral fracture. INTERVENTION: Alendronate sodium (5 mg/d for 2 years and 10 mg/d for the third year) or placebo. MAIN OUTCOME MEASURES: Occurrence and severity of back pain, number of days with back pain, and number of days of bed rest or limited activity because of back pain during 3 years of follow-up. RESULTS: Irrespective of treatment assignment, women with new, clinically recognized vertebral fractures during follow-up had an increased risk of days of bed disability and days of limited activity because of back pain after the fracture. Women receiving alendronate reported an average of 3.2 fewer days of bed rest (P = .001) and 11.4 fewer days of limited activity (not including days of bed rest) because of back pain (P = .04) during follow-up than those receiving placebo. In the alendronate group, relative to the placebo group, there was a reduced risk of 1 or more bed-rest days (relative risk, 0.68; 95% confidence interval, 0.53-0.87), of 7 or more bed-rest days (0.44; 0.30-0.64), and of 7 or more limited-activity days (0.87; 0.76-0.99). There were no statistically significant differences between treatment groups in the frequency of days of back pain or increases in back-related disability between baseline and study end. CONCLUSION: In postmenopausal women with preexisting vertebral fracture, alendronate therapy for 3 years reduced the number of days of bed disability and days of limited activity caused by back pain.

High resolution CT scan of temporal bone fractures: association of facial nerve paralysis with temporal bone fractures.

This radiologic study analyzed high resolution computed tomographic (CT) scans of 22 patients with temporal bone fractures. There were 19 males and three females. Fifteen of 22 had clinical evidence of facial nerve injury ranging from mild paresis to complete paralysis. The high resolution CT scan analysis identified a characteristic fracture of the temporal bone in every patient with facial nerve injury. A high percentage of these fractures (68%) could be classified as mixed and did not fall into a longitudinal or transverse fracture category. The characteristic fracture extends from the petrotympanic fissure at the glenoid fossa to the anterior inferior aspect of the medial bony external auditory canal. It resumes at the superior aspect of the external auditory canal (scutum) extending laterally along the external canal wall. If the vector force of the fracture is projected medially, it will cross the facial nerve in its horizontal portion. Often, the evaluation of trauma patients with routine CT scans for central nervous system (CNS) (brain) evaluation is inadequate for evaluation of temporal bone fractures. A high resolution CT scan should be performed when clinical criteria warrant its use. It is recognized that the incidence of facial nerve injury may be higher in this select population.

Fracture characteristics of acrylic bone cements. I. Fracture toughness.

The vital first phase of the overall materials study to protract the life of the total joint replacements is the identification of the fracture toughness and fatigue properties of bone cements. Information gained from fatigue testing, performed in a manner which simmulates in vivo conditions, and fracture toughness, which is a measure of the propensity of a crack to propagate, is the first step towards the prediction of the life of the total joint replacement. This study is concerned with the fracture toughness of Zimmer and Simplex-P cold-curing bone cements. Following cement fabrication conditions which closely approximate clinical procedures, fracture toughness testing was conducted on cement specimens which were immersed in bovine serum at 37 degrees C in order to simulate in vivo conditions. In addition, a similar study was completed on specimens, tested in air at ambient temperature for purposes of comparison. Results of this procedure, when analyzed by a Student's t-test at the 95% confidence level with eight degrees of freedom, indicate that both Zimmer and Simplex-P exhibit a higher fracture toughness in the simulated physiological environment. In order to determine whether the addition of barium sulfate to these cements compromises the fracture toughness, the above described testing rationale was repeated, indicating the existence of a complicated relationship between the different testing environments and barium sulfate. The importance of these results lies in the fact that an increased fracture toughness indicates that a cement will inherently exhibit a greater degree of resistance to the propagation of cracks, which could contribute to the ultimate failure of the total joint replacement.

The effect of a fracture protocol on hospital prescriptions after minimal trauma fractured neck of the femur: a retrospective audit.

Effective therapies for the treatment of osteoporosis and fracture have been available for a number of years. Despite this, there are numerous reports indicating very low uptake rates in those admitted to hospital with fracture. The aim of this retrospective audit was to assess the impact of a fracture protocol on inpatient prescriptions of osteoporosis therapy. A fracture protocol was arrived at by consensus and was based on recommendations from the Australian Fracture Prevention Summit, which included specific advice on the commencement in hospital of calcium, vitamin D, synthetic estrogen receptor modulators (SERMs) and bisphosphonates. We studied subjects who were treated for fractured neck of the femur at Royal Hobart Hospital from March 2002 to March 2004 and included 161 prior to the start of the protocol and 93 after. As compared to the baseline period, subjects after the introduction of the protocol had higher rates of in-hospital prescription for any treatment (58 vs. 36%, P <0.01), calcium (51 vs. 26%, P <0.01), vitamin D (48 vs. 29%, P <0.01) and oral bisphosphonates (24 vs. 5%, P <0.01), but not SERMs as expected (1 vs. 1%, P =0.70). Additional factors affecting the decision to start any treatment included in-hospital death (OR 0.16, 95% CI 0.05-0.49), dementia (OR 0.39, 95% CI 0.21-0.74), a trend for female sex (OR 1.79, 95%CI 0.96-3.36), but not age. In conclusion, a structural approach to changing hospital policy from the top down is effective at substantially increasing the usage of effective therapy after fractured neck of the femur.

Long-term trends in hip fracture prevalence: the influence of hip fracture incidence and survival.

In this population-based descriptive study covering the 65-year period, 1928-92, there was a 5-fold increase in hip fracture prevalence among Rochester, Minnesota residents between 1928-42 and 1973-82, from 135.8 to 675.8 per 100,000. This change was dictated almost entirely by an increase in the incidence of first hip fractures due to moderate trauma (n = 2058) that was observed among Rochester women through 1950, and among men through 1980, that affected all age groups. Declining incidence rates thereafter led to a 9% fall in hip fracture prevalence from 1973-82 to 1983-92 to a rate of 612.7 per 100,000. A 13.7-year increase in age at first hip fracture over the study period was accounted for by aging of the underlying population, and a comparable 13.9-year increase in the age at death following hip fracture appeared to result from improved survival in the population generally. Thus, trends in hip fracture prevalence were mainly determined by changes in incidence rather than relative changes in age at onset and death following hip fracture.
