A retrospective review of surgical outcomes in adolescents with idiopathic scoliosis. ⋯ Overweight adolescents (BMI % >or=85) had a greater thoracic kyphosis before surgery compared with their healthy weight peers. Body mass, however, did not affect the ability to achieve coronal or sagittal scoliotic deformity correction, and did not increase perioperative morbidity or mortality. These findings were either influenced by the small sample size of this cohort, or because the comorbidities responsible for increased perioperative complications in adults, had not yet developed in this adolescent population.

Comparative Study Controlled Clinical Trial
Quantitative analysis of back muscle degeneration in the patients with the degenerative lumbar flat back using a digital image analysis: comparison with the normal controls.
The degree of back muscle degeneration was quantified in patients with a degenerative lumbar flat back and a normal control group by magnetic resonance (MR) imaging and a digital image analysis technique. ⋯ T2 weighted MR Image analysis of the paravertebral back muscles in patients with degenerative lumbar flat back showed significant fat infiltration compared with those in the normal control using digital image analysis. Digital image analysis of the paravertebral back muscles is a useful tool for measuring the degree of paravertebral back muscle degeneration.

Randomized Controlled Trial Comparative Study
Self-report measures best explain changes in disability compared with physical measures after exercise rehabilitation for chronic low back pain.
Sixteen-week intervention for chronic patients with low back pain (LBP) with 9-month follow-up. Primary randomization at 4 weeks into either supervised Swiss ball exercise or an exercise advice group. ⋯ Supervised exercise is a more successful subsequent to manual treatment compared with exercise advice. The improvements associated with this type of program were primarily manifested in the psychologic self-report measures rather than physical measurements.

Prospective clinical study. ⋯ The reported biomechanical principles of Dynesys do not reflect advantages in outcome compared with none or others stabilization systems after microsurgical radicular decompression reported in the literature.

A case report of late-onset paraplegia from an epidural abscess in a patient years after her instrumentation and fusion for scoliosis. ⋯ This case reports a delayed spinal epidural abscess years after removal of her implants for infection. This demonstrates that our patients remain at risk for reactivation of spinal infections even though they may be healthy hosts and may have had all foreign bodies removed as part of their treatment for deep postoperative infections. This case suggests that extensive unilateral decompression and debridement through a fusion mass is a viable treatment method in patients with fused spine.
