The natural history of 33 patients with 43 unreduced congenital dislocations of the hip was reviewed. The average age at the first consultation was 50 years. Four were men and 29 were women. Ten patients had bilateral and 23 unilateral complete dislocation. Average follow-up lasted 9.2 years. At the final follow-up 23 hips and 18 knees were painful. Lumbago was observed in 6 of 15 patients under the age of 50 and in 14 of 18 patients over the age of 50 at the final follow-up. The average Harris hip scores at the first and final consultations were 69 and 70, respectively. The average dislocation index was increased in the standing more than in the lying position. In unilaterally dislocated hips the average femorotibial angles in the ipsilateral and contralateral knees to the dislocated hip were 172 and 179 deg, respectively. Lumbar degenerative scoliosis of more than 5 deg was observed in 16 patients.

Lumbar radiographs of 120 adolescent elite skiers were evaluated for radiologic abnormalities by two independent observers. All athletes had no symptoms before the study. Radiographs were taken before enrollment of the students in elite level training. To determine the clinical significance of these abnormalities, all athletes were observed prospectively during the subsequent 2-year period for development of low back pain under high performance training. Anterior end plate lesions, Schmorl's nodes, posterior end plate lesions, spondylolysis, scoliosis, and spina bifida occulta were found. The depth of anterior end plate lesions showed a two-peak distribution, with peaks at 11% and 22% and a valley at 18% vertebral body height. The overall low back pain incidence was 12.5%. Students with severe anterior lesions (greater than 18% vertebral body height, n = 25) had significantly more low back pain (incidence, 32%) than did students without severe anterior lesions (incidence, 7.4%). Accordingly, students with severe anterior lesions had a significantly higher risk of having low back pain develop. Moderate end plate lesions and other abnormalities were not related to an increased incidence of low back pain. Adolescent students of elite sports with severe lumbar anterior end plate lesions have an increased risk of having low back pain develop under high performance training.

References to histochemistry are extensive for human limb muscles but occur less frequently in relation to vertebral muscle. Most vertebral muscle literature has been concerned with muscle fibre characteristics in the lumbar and thoracic spine, due in large part to the incidence of low back pain and idiopathic scoliosis. However few studies have investigated the histochemical composition of neck muscles in humans: and, to our knowledge, no previous study has examined the antagonistic longus colli and multifidus muscle pair. In addition, while age-related segmental degeneration is most prominent between C5 and C7, it is not known whether these osteoligamentous changes are paralleled by changes in muscle fibre ratio. Tissue blocks comprising muscle and bone from C5-C7 segments were harvested at autopsy from 16 subjects with ages ranging from 4 to 77 years. The prevertebral longus colli and postvertebral multifidus muscle pairs were randomly selected from one or other side in each subject. The tissue was frozen, sectioned and histochemically stained for myofibrillar adenosine triphosphatase. Analysis of muscle fibre types was performed by light microscopy. Wilcoxon paired t-tests were used to ascertain whether intramuscular and intermuscular differences in fibre composition were significant. In addition, correlation and regression analyses were used to determine whether fibre type proportions changed in either muscle with increasing age. The present study has revealed histochemical differences between longus colli and multifidus at the level of the C5-C7 vertebral segments. Multifidus comprises a significantly greater proportion of type I than type II fibres. Longus colli comprises a significantly greater proportion of type II fibres than multifidus. Further there were no changes in fibre type proportion in either muscle with increasing age. These observations suggest that longus colli responds equally to postural and phasic demands, whereas multifidus is predominantly postural. Also it would appear that age-related structural alterations in lower cervical segments are not paralleled by changes in muscle fibre ratio.

Surgery in acute and/or chronic low back pain is still a matter of intensive and controversial discussions. A vast number of minimally invasive or so called semi-invasive procedures have been published in the last 3 decades, but evidence-based data on efficacy and benefit of most of these techniques are still lacking. However, empirical data suggest good or at least satisfactory clinical results for a limited number of procedures if they are applied under restrictive indication criteria. Discogenic low back pain and lumbar spinal stenosis belong to the most frequent diagnoses associated with low back pain. This article gives a survey on definitions, indication criteria and modern surgical or semi- invasive techniques used for the treatment of these two pathologic entities. Discogenic low back pain: This clinical and morphological entity is defined as low back pain arising mainly from disc degeneration. Pain generators are usually nociceptors in the cartilaginous endplates, in the outer anulus fibrosus as well as in the periosteum of the vertebral bodies. Clinical symptoms correlate with morphologic changes detected with MR-imaging (modic type I) or with contained disc protrusions mainly without neurological symptoms. Surgery is rarely indicated, spontaneous remissions occur in more than 60% of all cases. Spinal fusion has been the only surgical option in cases which did not respond to conservative therapy. Recently, electro-thermal modulation of the posterior anulus fibrosus has been published as a semi- invasive technique to relieve low back pain generated by fissures in the outer anulus and ingrowing nociceptors (intradiscal electro-thermal therapy, IDET(TM)). First results are promising, however, prospective randomised studies comparing this technique with conservative therapy are still lacking. The same is true for artificial nucleus pulposus replacement using hydrogel cushions implanted in the intervertebral space after removal of the nucleus pulposus from posterior or through an anterior approach (PDN, prosthetic disc nucleus(TM)). In cases with severe disc degeneration total disc replacement is another innovative option (ProDisc(TM)). Two metal endplates with titanium surface coating are implanted through a minimal invasive anterior approach (mini-laparotomy). A polyethylene inlay anchored in the caudal endplate holds the distance between the endplates and preserves the physiological range of motion between the two vertebral bodies. Degenerative lumbar spinal stenosis: Narrowing of the spinal canal due to degenerative changes of the disc, the facet joints and thickening of the yellow ligament is a geriatric disease which is diagnosed in increasing numbers within the last 10 years. More than 80% of the patients present with low back pain in association with neurogenic claudication. Neurological symptoms at rest are less frequently found. The spontaneous course shows progressive symptoms in more than 50% of all patients. More than 35% of the patients have associated diseases which might influence the perioperative course, complication rates and outcomes of surgery. Surgery is indicated in patients with progressive neurological symptoms, unacceptable decrease of quality of life or progressive intractable pain. In patients with mainly "leg symptoms" microsurgical mono- or multisegmental decompression is the procedure of choice. If low back pain is predominant and associated with degenerative instability such as degenerative spondylolisthesis or lumbar scoliosis, decompression must be combined with instrumented spinal fusion. In general a restrictive indication for surgery must be recommended especially for spinal fusion procedures. Non-fusion techniques such as intradiscal electro thermal therapy or spine arthroplasty with replacement of nucleus pulposus or total disc show promising early results; however, little is known about the long-term effect. It should be a principle to apply surgery in the least invasive way.

The role of leg length discrepancy (LLD) both as a biomechanical impediment and a predisposing factor for associated musculoskeletal disorders has been a source of controversy for some time. LLD has been implicated in affecting gait and running mechanics and economy, standing posture, postural sway, as well as increased incidence of scoliosis, low back pain, osteoarthritis of the hip and spine, aseptic loosening of hip prosthesis, and lower extremity stress fractures. Authors disagree on the extent (if any) to which LLD causes these problems, and what magnitude of LLD is necessary to generate these problems. This paper represents an overview of the classification and etiology of LLD, the controversy of several measurement and treatment protocols, and a consolidation of research addressing the role of LLD on standing posture, standing balance, gait, running, and various pathological conditions. Finally, this paper will attempt to generalize findings regarding indications of treatment for specific populations.

This retrospective study was performed to evaluate the results of the treatment of late posttraumatic spinal disorders. Five patients with thoracolumbar kyphosis, two with paralytic kyphoscoliosis and two with posttraumatic instability with pain but without neurologic symptoms and apparent deformity, were treated surgically. Various surgical procedures were performed depending on the pathologic conditions. Corrections achieved in the sagittal and frontal planes were analyzed on radiographs after a mean follow-up of 4.4 years. In cases of angular kyphosis, the deformity measured 48.8 degrees on average before operation and 9.3 degrees afterward. Preoperative neurologic impairments were improved in all cases. Patients with paralytic scoliosis benefited from an average surgical correction of 68%. The restoration of truncal balance helped the patients to regain a normal sitting posture. Pain was reduced in all patients after surgery, as it was in patients with low back pain caused by posttraumatic instability without deformity. The results of the current study emphasize the importance of adequate management of spinal injuries to prevent late spinal sequelae.

Intervertebral disc herniation is a rare condition in childhood and adolescence, although some cases have already been reported in the literature. We present the case of a 15 year-old-girl with low back pain and scoliosis. She had no previous history of trauma or collagen diseases. MRI showed L4-L5 and L5-S1 disc herniations and no further bone and structural changes. After two level discectomy, pain ceased and scoliosis improved, without further treatment. Based on her evolution and on what has already been reported in literature, we consider that scoliosis associated with disc herniation in young patients is most likely to be only an anthalgic position, not indicative of further structural changes.

We have analyzed the radiologic findings on the lumbar spine and the clinical symptoms in patients with rheumatoid arthritis (RA). A total of 106 patients who fulfilled the revised criteria of the American Rheumatism Association were subjected. All of the patients were asked to fill out a questionnaire about the existence of low back pain, leg pain, and leg numbness. Radiologic features of the lumbar spine, including scoliosis, spondylolisthesis, disc space narrowing, endplate erosion, osteophyte, and osteoporosis, were checked. Radiographs of the cervical spine were also taken. The clinical background of RA, such as mutilating disease or not, was assessed. Forty-two patients (40%) had the symptoms of low back pain. Abnormal radiologic findings in lumbar spine were detected in 57%. The prevalence of clinical symptoms tended to be higher in the patients with endplate erosion. Forty-two percent of the patients had both lumbar and cervical lesions. The prevalence of lumbar lesion was not high in the mutilating type of RA, except for facet erosion and severe osteoporosis. The patients with pulse steroid therapy revealed a higher prevalence of vertebral fracture. From these results, we concluded that lumbar lesions were frequently observed in patients with RA. The possibility of lumbar lesions as well as the lesions in the cervical spine and peripheral joints should be examined in patients with RA.

Degenerative scoliosis of the lumbar spine affects a significant number of adults. Although the etiology of this condition is not clear, the most commonly implicated causes include osteoporosis and degenerative disc disease. Clinically, patients with this condition most commonly complain of axial low back pain, but they may also present with radicular complaints. This pain may be generated directly by the facet joints or may be due to nerve root impingement or traction. Imaging of this spinal deformity should include both plain radiographs and computed tomographic myelography. Nonoperative therapy is ideal, but surgery is indicated for severe radicular symptoms refractory to conservative management or for progression of the curve. Ideally, surgical treatment should consist of decompression and fusion with segmental instrumentation.

A survey of adolescent schoolchildren and their parents through a self-administered questionnaire was conducted to determine the prevalence of low back pain (LBP) in schoolchildren and their parents and to assess its association with exposure to known and presumed risk factors. A previously validated, self-administered questionnaire was used for collecting information on back pain history, anthropometric measures, physical and sports activity, academic problems, hours of leisure sitting, smoking, and alcohol intake. Schoolchildren between the ages of 13 and 15 in schools of the island of Mallorca and their parents (n=16,394) took part in the study. The lifetime prevalence of LBP was 50.9% for boys and 69.3% for girls; point prevalence (7 days) was 17.1% for boys and 33% for girls. There was a significant association with LBP and pain in bed (OR=13.82, 95% CI: 10.47-18.25, P<0.001), reporting scoliosis (OR=2.87, 95% CI: 2.45-3.37, P<0.001), reporting difference in leg length (OR=1.26, 95% CI: 1.02-1.56, P=0.033), practice of any sport more than twice a week (OR=1.23, 95% CI: 1.09-1.39, P=0.001) and being female (OR=1.11, 95% CI: 1.04-1.19, P=0.001). There was no association found between LBP and body mass index, the manner in which books were transported, hours of leisure sitting, alcohol intake or cigarette smoking. Among parents, the lifetime prevalence of LBP was 78.2% for mothers and 62.6% for fathers; point prevalence (7 days) was 41% for mothers and 24.3% for fathers, and there were significant associations with LBP and pain in bed (OR=18.07, 95% CI: 14.72-22.19, P<0.001), report of scoliosis (OR=8.77, 95% CI: 6.44-11.95, P<0.001), report of difference in leg length (OR=2.21, 95% CI: 1.60-3.04, P<0.001), being a university graduate (OR=1.89, 95% CI: 1.21-2.98, P=0.006), being female (OR=1.49, 95% CI: 1.33-1.67, P<0.001), and swimming (OR=1.10, 95% CI: 1.4-1.18, P=0.002). There was no association found between LBP and alcohol intake, cigarette smoking or the practice of other sports. Although there was a positive association in terms of scoliosis between biological parents and their children (P<0.001), there was no association found in familial (biological or not) occurrence of LBP. The prevalence of LBP among adolescents in southern Europe is similar to northern Europe, it is comparable to that in adults, and is associated with several factors. There is a strong association between pain in bed or upon rising in both adolescents and adults. Scoliosis, but not LBP, appears to be related to heredity. Further longitudinal studies are necessary to establish risk factors that are predictive for LBP in adolescents.
