Comparative StudyCorrelative analysis of lateral vertebral radiographic variables and medical outcomes study short-form health survey: a comparative study in asymptomatic volunteers versus patients with low back pain.
This prospective comparative study was designed to investigate the possible link between SF-36 functional status and lateral roentgenographic variables of the standing lumbar spine in patients with low back pain (LBP) versus asymptomatic volunteers. To the authors' knowledge, no previous studies have correlated SF-36 scores and sagittal roentgenographic variables in patients with LBP versus asymptomatic individuals. A total of 100 male volunteers, used as controls, and an equal number of age-, height-, and weight-comparable patients of the same ethnicity with chronic LBP were compared on the basis of roentgenographic and SF-36 data. ⋯ For the patients with LBP this study showed that General health, Physical Functioning, Role-Emotional, Social Functioning, and Bodily Pain were significantly correlated with age, height, L1-L2 inclination, distal lordosis, L2-L5 index, and L4-L5 and L5-S1 disc index. This comparative study showed that the functional status of hard-working patients with chronic LBP is associated with degenerative changes on the lateral radiographs of the lumbosacral spine. Spine surgeons should take into consideration the results of this study in reconstruction of painful degenerative lumbosacral spine.

Case ReportsCyclic sciatica related to an extrapelvic endometriosis of the sciatic nerve: new concepts in surgical therapy.
Sciatic pain caused by endometriosis of the sciatic nerve is an uncommon clinical finding and seems to have been verified histologically in only a few cases. Patients complain of typical signs and symptoms of common sciatica that are cyclic in nature. ⋯ However, conservative surgery with excision of the endometriosis from the nerve can be successful in selected patients who wish to preserve reproductive function. We report a case of sciatic nerve involvement explored by magnetic resonance imaging, with endometriosis in contact with the nerve in the right sciatic trunk.

Comparative StudySingle-level lumbar spine fusion: a comparison of anterior and posterior approaches.
This study is a retrospective review of 122 patients who underwent single-level lumbar spine fusion. The objectives were to directly compare perioperative morbidity and early results of single-level anterior interbody posterolateral intertransverse process lumbar spine fusion and to provide objective findings that may be useful in selecting surgical method. Lumbar spinal fusion is a well-recognized surgical treatment of intractable low back pain resulting from DDD or spondylolisthesis. ⋯ This may in turn affect surgical outcome and hospital cost. However, both approaches to single-level lumbar fusion produce similar early fusion rates and clinical results. Revision fusions had poor early results regardless of approach.

Relationships between sagittal alignment of the cervical spine and morphology of the spinal cord and clinical outcomes in patients with cervical spondylotic myelopathy treated with expansive laminoplasty.
A total of 103 patients with cervical spondylotic myelopathy undergoing laminoplasty were retrospectively reviewed to evaluate whether sagittal alignment of the cervical spine and morphology of the spinal cord influence surgical outcomes. Sagittal alignment of the cervical spine did not influence surgical outcomes. ⋯ It is important to acquire anterior convexity of the spinal cord after surgery if laminoplasty is performed below C3. In patients with kyphosis, where anterior convexity of the spinal cord is not thought to be obtained postoperatively, it is possible that additional decompression of C2 improves outcome.
