Health-related quality of life using the SF-36 in patients with bipolar disorder compared with patients with chronic back pain and the general population.

BACKGROUND: The purpose of this study was to assess and compare the health-related quality of life of patients with bipolar disorder and chronic back pain and, in turn, to compare these results with those previously generated for the general population. METHODS: Subjects were patients with bipolar disorder (n=44), a comparison group of chronic back pain patients (n=30), and a population-based control sample (n=2,474). Health-related quality of life was assessed using the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36), a self-administered questionnaire in which lower scores are indicative of greater impairment. RESULTS: Patients with bipolar disorder had lower mean scores than the general population on all scales except Physical Functioning. Bipolar patients had significantly higher scores than chronic back pain patients in the categories of Physical Functioning, Role Limitations--Physical, Bodily Pain, and Social Function. There were no significant differences between bipolar disorder and chronic back pain groups in the Mental Health and Role Limitations - Emotional categories. LIMITATIONS: The results of the study are limited by the relatively small sample sizes of the bipolar and back pain patient groups. CONCLUSIONS: Patients with bipolar disorder had substantial impairment in health-related quality of life in comparison with the general population. Bipolar patients were less compromised in areas of physical and social functioning than chronic back pain patients but had similar impairment in mental health.

Measures of low back function: a review of reproducibility studies.

OBJECTIVE: The objective of the present study was to make a systematic literature review with preset quality criteria concerning reproducibility of the tests of the low back regarding strength, endurance and range of motion. DESIGN: Literature in Medline and local databases was reviewed for articles concerning the reproducibility of strength, endurance, and range of motion measurements. BACKGROUND: Measures of low back function are widely used, and are important for both clinical and research purposes in relation to low back problems. A review of the reproducibility of these tests has not previously been made. METHODS: After extensive discussion among all the authors, general evaluation parameters were defined for the quality assessment. Every study was graded from 0 to 2 for each parameter. Parameters evaluated were: number of subjects, subject description, method description, test/retest interval, description of results, and statistics. RESULTS: The literature search revealed a total of 79 studies. Most studies suffered from methodological weaknesses and only eleven studies received ten or more quality points (maximum 14). The results from the highest graded studies are highlighted. CONCLUSIONS: It may be concluded that there is a considerable lack of information about the reproducibility of functional measures for the low back, and therefore a recommendation for consensus is difficult. However, most tests performed in the sagittal plane are reliable for use on groups. RELEVANCE: Measures of low back function are thought to be of great importance for clinicians, and low back researchers in general. A review of reproducibility will be helpful both as a survey of tests, and to provide information on the usefulness in relation to the level of reproducibility.

Low back three-dimensional joint forces, kinematics, and kinetics during walking.

OBJECTIVE: The purpose of this study was to examine the three-dimensional low back loads, spinal motions, and trunk muscular activity during gait. Specific objectives involved assessment of the effects of walking speed, and arm swing on spinal loads, lumbar spine motion, and muscular activation. DESIGN: An in vivo modeling experiment using five male participants. Thirty walking trials were performed by each participant yielding five repeats of each condition (3 walking cadences x 2 arm swing conditions). BACKGROUND: Walking is often prescribed as a rehabilitation task for individuals with low back injuries. However, there are few studies which have examined the joint loading, spinal motions, and muscular activity present when walking. Additionally, the majority of studies examining spine loading during gait have used an inverse dynamics model, commencing at the cranial aspect of the body, approach which does not include the impulsive phases of gait (i.e. heel strikes and toe offs). METHODS: Low back joint forces (bone on bone) and moments were determined using an anatomically complex three-dimensional model (detailing 54 muscles and the passive structures acting at the low back) during three walking cadences and with free arm swing or restricted arm swing. In order to assess the influence of the transient factors such as heel contact on the joint forces a bottom up (from the feet to the lumbar spine) rigid link segment analyses approach was used as one input to the three-dimensional anatomic model. Lumbar spine motion and trunk muscle activation levels were also recorded to assist in partitioning forces amongst the active and passive tissues of the low back. RESULTS: Net joint anterior-posterior shear loading was the only variable significantly affected by walking cadence (fast versus slow P < 0.0003). No variable was significantly affected by the arm swing condition. Trends demonstrated an increase in all variables with increased walking cadence. Similarly, most variables, with the exception of axial twist and lateral bend lumbar spine motion and lateral joint shear, demonstrated increasing trends caused by the restriction of normal arm swing. CONCLUSIONS: Tissue loading during walking appears to be below levels caused by many specific rehabilitation tasks, suggesting that walking is a wise choice for general back exercise and rehabilitation programs. Slow walking with restricted arm swing produced more 'static' lumbar spine loading and motion patterns, which could be detrimental for certain injuries and tissues. Fast walking produced a more cyclic loading pattern.

Balance in chronic low back pain patients compared to healthy people under various conditions in upright standing.

OBJECTIVE: To determine whether balance responses of chronic low back pain patients differed from healthy controls under various upright standing conditions which challenged the balance system. METHODS: Eight chronic low back pain patients and eight controls performed seven postural tasks which involved manipulation of visual, vestibular, and proprioceptive input as well as body orientation. The unbiased root mean square, the mean power frequency and the mean position of the centre of pressure were calculated from force plate readings. A pain scale and two questionnaires were used to evaluate the severity of disability and the scores were correlated with the force plate measures. The reliability of the force plate measures was determined. RESULTS: A significant increase in the root mean square in the medial-lateral direction for the chronic low back pain patients as a group was found during tasks which involved removal of vision, especially when combined with increased task complexity. The root mean square and mean power frequency in the medial-lateral plane were reliable for the majority of the tasks. CONCLUSION: The root mean square in the medial-lateral direction was reliable and sensitive enough to measure an increase in postural sway of chronic low back pain patients as a group compared to healthy controls when the task involved increased complexity and removal of visual information. RELEVANCE: A reliable measure of whole body performance obtained during simple postural tasks, such as the root mean square in the medial-lateral plane, may be used to distinguish chronic low back pain patients as a group from a healthy population. Further uses may include the development and guidance of chronic low back pain treatment and evaluation of recovery progress.

Physical examination of horses with back pain.

The diagnosis of back pain is often a diagnosis of exclusion of other problems in the face of poor performance. It requires careful observation, thought, an open mind, and experience. The signs of back pain can be extremely variable and range from subtle to obvious. Obvious forelimb or hind limb lameness is not usually a sign of back pain. The most common differential diagnosis may be back pain secondary to degenerative joint disease of the hocks, fetlocks, or stifle. These diseases can mimic signs of back pain including lack of impulsion, shortening of the stride length, and change in the stride character similar to those seen with back pair.

[Low back pain and headache during immediate postpartum. Role of obstetrical epidural analgesia].

The rate of low back pain and headache following parturition seems to be higher in patients delivered under epidural analgesia. The aim of this study, performed in the immediate postpartum (up to 3rd day) and including 200 patients delivered vaginally, was to assess the incidence and the risk factors of low back pain and headache. A total of 31.5% of them complained of low back pain (LBP+) after parturition. They were significantly younger than those without low back pain (LBP-) (p < 0.03) and have had significantly more often epidural analgesia (p < 0.05). However, there were no statistically significant differences concerning weight, weight gain, parity, duration of labour and duration of epidural analgesia. The LBP+ patients complained significantly more often of cervical (p < 0.04) and low back pain (p < 0.02) during pregnancy, than the LBP-. In the immediate postpartum period, cervical and dorsal pain as well as headache occurred significantly more often in LBP+ than in LBP+ (p < 0.001). The intensity of low back pain during pregnancy (p < 0.006). Risk factors for postpartum LBP were epidural analgesia (OR = odds ratio = 6.59), LBP (OR = 6.50) and cervical pain (OR = 2.75) during pregnancy. The influence of epidural analgesia is questionable, as there was no difference between duration of labour and duration of epidural analgesia, if used, between the two groups. Patients for whom epidural analgesia was required are probably more susceptible to pain during pregnancy. Patients who suffered from postpartum headache (PPHDA+) were comparable to those who did not (PPDHA-).(ABSTRACT TRUNCATED AT 250 WORDS)

Supplementation with alkaline minerals reduces symptoms in patients with chronic low back pain.

The cause of low back pain is heterogeneous, it has been hypothesised that a latent chronic acidosis might contribute to these symptoms. It was tested whether a supplementation with alkaline minerals would influence symptoms in patients with low back pain symptoms. In an open prospective study 82 patients with chronic low back pain received daily 30 g of a lactose based alkaline multimineral supplement (Basica) over a period of 4 weeks in addition to their usual medication. Pain symptoms were quantified with the "Arhus low back pain rating scale" (ARS). Mean ARS dropped highly significant by 49% from 41 to 21 points after 4 weeks supplemention. In 76 out of 82 patients a reduction in ARS was achieved by the supplementation. Total blood buffering capacity was significantly increased from 77.69 +/- 6.79 to 80.16 +/- 5.24 mmol/L (mean +/- SEM, n = 82, p < 0.001) and also blood pH rose from 7.456 +/- 0.007 to 7.470 +/- 0.007 (mean +/- SEM, n = 75, p < 0.05). Only intracellular magnesium increased by 11% while other intracellular minerals were not significantly changed in sublingual tissue as measured with the EXA-test. Plasma concentrations of potassium, calcium, iron, copper, and zinc were within the normal range and not significantly influenced by the supplementation. Plasma magnesium was slightly reduced after the supplemenation (-3%, p < 0.05). The results show that a disturbed acid-base balance may contribute to the symptoms of low back pain. The simple and safe addition of an alkaline multimineral preparate was able to reduce the pain symptoms in these patients with chronic low back pain.

Health care providers should use a common language in relation to low back pain patients.

Uncertainty is the rule rather than the exception when it comes to the underlying causes of 'common' or 'non-specific' low back pain. It may be called many names, depending on whether the diagnostic term is descriptive, anatomopathological or physiopathological. Classifications have been devised, including various criteria: symptoms and signs, duration, treatment, consequences of low back pain on the patients' daily life, etc. Because back pain frequently runs a recurrent course, functional and pain outcomes need to be considered separately: chronic disability and chronic pain may not be parallel. Thus, pain duration (e.g. acute, transient, recurrent, chronic) is only one element in the definition of chronicity. These difficulties in defining and classifying non-specific low back pain may lead to communication problems among health professionals as well as between patients and health professionals. These difficulties raise questions such as: what kind of diagnostic term should we use to avoid dramatization of non-specific low back pain? how can we improve the definition of long-term low back pain? and how can we assure and reassure the patient that this condition is benign in the majority of the population?

Compliance among general practitioners in France with recommendations not to prescribe bed rest for acute low back pain.

UNLABELLED: Acute low back pain is a very common reason for general practitioner visits. OBJECTIVE: To evaluate practices among French general practitioners regarding the prescription of bed rest in patients with low back pain. METHODS: 2000 general practitioners were to include the first three patients presenting within the first 3 d of onset of acute low back pain without nerve root pain. The characteristics of the pain, social and demographic characteristics of the patients, and treatments prescribed by the physicians were recorded. RESULTS: 5355 patients were included, of whom more than half had a history of one or more episodes of low back pain. The mean pain severity score on a 100-mm visual analog scale was 57.2 +/- 22.7 mm. Bed rest was recommended to 27.6% of the patients, for a mean duration of 4.4 d. Patients to whom bed rest was recommended were significantly more likely than the other patients to have chronic low back pain (32.1% vs. 26.5%) and received a greater number of medications. Bed rest was associated with significantly poorer outcomes in the multivariable analysis adjusting for confounding factors. CONCLUSION: Recommendations to avoid bed rest in patients with acute low back pain are widely followed in France. Furthermore, our results confirm that bed rest is associated with poorer outcomes.

Clinical and psychological correlates of lumbar motion abnormalities in low back disorders.

BACKGROUND CONTEXT: Low back pain (LBP) and low back disorders (LBDs) identify a complex constellation of conditions that frustrate both diagnosis and therapy. Dynamic quantitative assessment and questionnaire instruments directed toward psychosocial and situational variables provide potentially powerful tools for determining functional pathology and potentially outcome. PURPOSE: Our goal was to independently assess clinical correlates of a trunk motion measurement device, the lumbar motion monitor (LMM). The reliability of the LMM as a clinical test was assessed by comparison with an independent medical examination and biobehavioral questionnaires. STUDY DESIGN/SETTING: There were three study components. A multispecialty physician panel that administered a structured physical examination contributed to a clinical correlation case series study. Standardized outcomes and risk identification questionnaires were administered to the case population. Finally, the LMM was administered in a customary fashion to the same population. PATIENT SAMPLE: Nineteen subjects were recruited on the basis of criteria that included symptoms of chronic recurrent low back pain. This was an employed and active, although impaired, population. Eighteen of the subjects were currently employed with limited lost work time, but chronic and recurrent pain was a common feature. OUTCOME MEASURES: Questionnaire outcome measures were both characterologic and situation based. In addition to providing diagnoses, the physician panel was also asked to offer certain qualitative assessments, such as rehabilitative potential and functional level pertinent to activities of daily living. The impact of LMM measures on physician decision making was also assessed. Trunk angular measurements were used to assess function of patients with chronic low back disorders. METHODS: Kinematic performance on the LMM was expressed as three probability scores. These were the likelihood of abnormality, the "sincerity of effort" (exacerbation or aggravation of impairment), and the likelihood of structural anatomic disease. These variables were examined against established self-report measures of pain and disability. RESULTS: The LMM and physician panels were in agreement on the presence or absence of abnormality. LMM findings tended to be more consistent with clinical history than the clinical examination. The LMM results were also generally consistent with the self-reported measures of pain and disability: a high likelihood of structural disease was associated with depression, somatization, poor health perception and diminished vitality. CONCLUSIONS: The LMM appears to be a useful assessment tool for gauging the presence of LBP and LBD. It was accurate in detecting abnormality when abnormality was determined by clinical history and physician diagnosis. The LMM's differentiation of mechanical low back disease (nonanatomically specific disorders) from structurally specific low back disease was not consistent with a parallel clinical differentiation. Larger trials in a prospective format and studies on a chronically disabled population seem warranted. In an impaired but less disabled population, elevated pain and somatization did not appear to weaken the effort during testing.

Stronger back muscles reduce the incidence of vertebral fractures: a prospective 10 year follow-up of postmenopausal women.

The long-term protective effect of stronger back muscles on the spine was determined in 50 healthy white postmenopausal women, aged 58-75 years, 8 years after they had completed a 2 year randomized, controlled trial. Twenty-seven subjects had performed progressive, resistive back-strengthening exercises for 2 years and 23 had served as controls. Bone mineral density, spine radiographs, back extensor strength, biochemical marker values, and level of physical activity were obtained for all subjects at baseline, 2 years, and 10 years. Mean back extensor strength (BES) in the back-exercise (BE) group was 39.4 kg at baseline, 66.8 kg at 2 years (after 2 years of prescribed exercises), and 32.9 kg at 10 years (8 years after cessation of the prescribed exercises). Mean BES in the control (C) group was 36.9 kg at baseline, 49.0 kg at 2 years, and 26.9 kg at 10 years. The difference between the two groups was still statistically significant at 10 year follow-up (p = 0.001). The difference in bone mineral density, which was not significant between the two groups at baseline and 2 year follow-up, was significant at 10 year follow-up (p = 0.0004). The incidence of vertebral compression fracture was 14 fractures in 322 vertebral bodies examined (4.3%) in the C group and 6 fractures in 378 vertebral bodies examined (1.6%) in the BE group (chi-square test, p = 0.0290). The relative risk for compression fracture was 2.7 times greater in the C group than in the BE group. To our knowledge, this is the first study reported in the literature demonstrating the long-term effect of strong back muscles on the reduction of vertebral fractures in estrogen-deficient women.

Socioeconomic variation in back and joint pain in Finland.

UNLABELLED: Differences in the prevalence of back and joint pain by occupational class and education were studied in surveys representative of adult Finns. The effects of lifestyle factors and mental distress on these differences were also analysed. The material comprised 3915 women and 3629 men, all occupationally active. Occupational class and level of education were associated with back and joint pain; the associations were more obvious in men than in women. Among men, the age-adjusted odds ratio of joint pain in farmers was 3.2 (95% CI: 2.1-5.0), in manual workers 2.6 (1.9-3.6), in entrepreneurs 2.4 (1.5-3.7) and in lower white-collar workers 1.7 (1.1-2.4) as compared with upper white-collar employees. Similar odds ratios of back pain were 2.1 (1.6-2.9) in farmers, 1.8 (1.5-2.3) in manual workers, 1.7 (1.2-2.4) in entrepreneurs and 1.4 (1.1-1.7) in lower white-collar workers. Most of the associations persisted in multivariate analyses, in which height, marital status, lifestyle (smoking, leisure-time physical activity and body mass index (BMI)) and mental distress were considered; in these models, mental distress was consistently associated with pain. Back pain was associated with smoking in men and with BMI in women; BMI was also associated with joint pain in both sexes. In women, height showed an association with back pain for which a doctor had been consulted. Marital status, alcohol consumption, leisure-time physical activity and the urbanization level of the community were not important as determinants of pain. CONCLUSION: Obvious differences occurred in back and joint pain by indicators of social class that were not due to socioeconomic differences in lifestyle, height or mental distress.

Psychophysiological effects of back massage on elderly institutionalized patients.

An experimental design was used to measure the effects of back massage on anxiety levels of elderly residents in a long-term care institution. Twenty-one residents, 17 females and four males, participated in the study. Subjects were randomly assigned to three groups which received 'back massage with normal conversation', 'conversation only' and 'no intervention' respectively. The dependent variable, anxiety, was measured prior to back massage, immediately following, and 10 minutes later, on four consecutive evenings. The Spielberger Self-Evaluation Questionnaire (STAI), electromyographic recordings, systolic blood pressure, diastolic blood pressure (DBP) and heart rate were used as measures of anxiety. Analysis of variance was used to examine differences in group mean scores over the pre-test to post-test, post-test to delayed time interval, and pre-test to delayed time intervals, Scheffé comparisons being made where indicated. With the exception of mean DBP which showed no change from pre-test to post-test and HR which increased from post-test to delayed time interval, there was a statistically insignificant decrease in mean scores on all variables in the back massage group from pre-test to post-test and from post-test to delayed time interval. There was a statistically significant difference in the mean anxiety (STAI) score between the back massage group and the no intervention group. The difference between the back massage group and the conversation only group approached statistical significance.(ABSTRACT TRUNCATED AT 250 WORDS)

Barriers to patient information provision in primary care: patients' and general practitioners' experiences and expectations of information for low back pain.

BACKGROUND: As patient involvement in health-care increases, the role of information is crucial, especially in conditions where self-management is considered an integral part of care. However, the suitability and applicability of much patient information has not been appraised in terms of how far it meets patients' information needs. AIMS: To ascertain patients' and clinicians' experiences and expectations of information in low back pain in order to suggest a suitable 'patient-centred' content for a patient information pack to be used in a primary care setting. METHODS: A qualitative study using semi-structured interviews with General Practitioners (GPs) (n = 15) and focus groups comprising patients with low back pain (n = 37). RESULTS: Barriers to information-giving for low back pain in primary care exist. Patients are dissatisfied with the information they receive from their GPs, especially regarding diagnosis and treatment. Patients tend to access information from a variety of other sources, which is often contradictory, conflicts with research evidence and leads to unreasonable expectations. GPs have varying views regarding the value of patient information and are equivocal about their roles as information providers. Although The Back Book is generally acceptable as a patient information leaflet for low back pain, attention to the tone of the text is required. CONCLUSIONS: Barriers exist to patient information provision, both generally and for low back pain, which need to be addressed in order to close the gap between strategy and implementation. Improving clinician communication skills and involving patients in developing information materials which meet their needs are crucial to this process.

The insulin tolerance test and ovine corticotrophin-releasing-hormone test in episodic cluster headache. II: Comparison with low back pain patients.

Hypothalamic involvement has been invoked to explain the periodicity of the cluster periods and rhythmicity of the pain attacks in cluster headache. To explore this hypothesis the ovine corticotrophin-releasing headaches sufferers during both cluster period and remission. A group of low back pain patients and healthy subjects comprised the control populations. For the o-CRH test, 7 healthy subjects, 7 low back pain patients, 6 cluster headache patients in remission, and 12 in cluster period were studied. Five healthy subjects, 7 low back pain patients, 6 cluster headache patients in remission, and 9 cluster period were administered the insulin tolerance test. Significantly increased basal cortisol levels were found in cluster headache patients in both illness phases (p < 0.0001), but not in low back pain patients. Significantly reduced cortisol response to the o-CRH test was observed in cluster headache patients in both phases compared to healthy controls (p < 0.02). A blunted ACTH and cortisol response (p < 0.0001 and p < 0.003 respectively) to the insulin tolerance test was present in cluster headache patients in both phases of the illness compared to healthy subjects and low back pain patients. On the contrary, the ACTH surge after insulin induced hypoglycemia was significantly increased in the low back pain patient group (p = 0.02). These results suggest that the altered hypothalamic-pituitary-adrenal axis responsiveness in cluster headache patients is not a consequence of the pain, and point to a central, probably hypothalamic derangement in this pathology.

[Effects of elastic lumbar belts on the effect of a muscle training program for patients with chronic back pain].

QUESTION: Aim of the study was to evaluate the influence of elastic lumbar belts on the effect of muscle training for patients with low back pain. METHODS: 97 male subjects aged from 23 to 42 years with and without low back pain participated in the investigation. The low back pain patients (n = 63) were randomized into a training group without and a training group with elastic lumbar belts and a control group. The subjects with healthy backs (n = 34) were divided age-matched into a training group with elastic lumbar belts and a control group. The three training groups took part in a muscle strenghtening program over 8 weeks. The control groups did not receive any alternative physiotherapeutic treatment. All groups were tested at the beginning, after 8 weeks and further 6 months later. RESULTS: The data obtained for the control groups remained virtually unchanged over the period of investigation. However, a significant increase of the muscle flexibility of the lower limbs could be proved for the training groups. Furthermore the coordination between the lumbar spine and pelvis when flexing the trunk deeply forward was more leveled out for the training groups with patients suffered low back pain. The results confirmed a reduction for pain severity and for limitations in activities of daily living as well. The modifications for the criteria investigated were significant stronger for the training group with patients using the elastic lumbar belt. CONCLUSIONS: The effectiveness of the muscle strengthening program for patients with low back pain could be improved significantly by means of the elastic lumbar belt as an applicable therapy instrument in the functional rehabilitation of spinal injuries.

[Efficacy of inpatient rehabilitation for chronic back pain in Germany: a systematic review 1980-2001].

BACKGROUND: Chronic back pain has a high personal impact, is frequent and of outstanding economical relevance. Analysis of the international literature indicates strong or moderate evidence for the effectiveness of multimodal multidisciplinary team care of chronic back pain. Our review aims at a complete review and critical appraisal of German studies of inpatient medical rehabilitation. METHODS: We conducted a systematic search for relevant German studies (1/1980 - 6/2001) using electronic data bases, manual search of congress abstracts and postal questionnaires of 712 German rehabilitation clinics. Relevant studies were categorized according to the recommendation of the Cochrane Back Review Group. For all studies, aims, participants, type of intervention, evaluation time, main outcomes and results were extracted and tabulated. The effect size for 6 central outcome parameters (pain intensity, functional status, catastrophizing, depression, vitality, days on sickness leave) were calculated using pre-post comparisons and were integrated into short and long term weighted means of intra-group effect sizes. RESULTS: 30 studies, both controlled and uncontrolled, report a multitude of positive changes with inpatient rehabilitation treatment. Improvements included both somatic and psychological parameters. However, methodological quality was often poor; only three studies fulfilled the criteria for high quality. Comparison of meta analyses of German and international studies indicates partly good agreement (e. g. changes in pain intensity), partly discrepancies (e. g. functional ability in daily activities). Taken together, inpatient rehabilitation treatment for chronic low back pain in Germany appears to be of low to moderate efficacy. DISCUSSION AND CONCLUSIONS: In the era of evidence based medicine, inpatient rehabilitation has to show its usefulness, necessity and efficiency as any other type of health care. For the German system of inpatient rehabilitation of chronic back pain available evidence is not conclusive, due to a lack of randomised controlled studies. The prevailing design of observational cohort studies has severe limitations in proving a causal relationship between outcomes and intervention. The international literature however provides more valid evidence in favour of the multimodal multidisciplinary intervention in chronic back pain. Under the assumption of a "class effect" of medical rehabilitation the German data seem to corroborate the conclusions drawn from international studies.

A case of severe low back pain associated with Richard disease (lumbosacral transitional vertebra).

The imaging findings in some cases of low back pain are difficult to describe and the pathophysiology is not clear because subjective findings are usually difficult to document. This report concerns a rare case about the lumbosacral joint causing persistent severe back pain which in itself does not usually have any pathological meaning. We describe the diagnosis, treatment, and outcome of a patient suffering from low back pain with lumbosacral transitional vertebra. The radiological examination showed the congenitally malformed transverse processes of the 5th lumbar vertebra to create a facet joint-like shape at the sacral ala region on both sides. Surgery resulted in immediate disappearance of the low back pain. When the lumbosacral junction shows some instability without fusion, the joint-like region could be the cause of low back pain. The lumbosacral transitional vertebra may be associated with low back pain. Electric denervation of the space between the transverse process of 5th lumbar vertebra and sacral ala is minimally invasive and effective for pain eradication.
