Randomized Controlled Trial Comparative Study
Two-year outcome after lumbar microdiscectomy versus microscopic sequestrectomy: part 1: evaluation of clinical outcome.
Single-center randomized prospective study at a university hospital. ⋯ Reherniation rates within 2 years after sequestrectomy and microdiscectomy are comparable. However, outcome after microdiscectomy seems to worsen over time, whereas it remains stable after sequestrectomy. Thus, 2-year follow-up revealed clinical results favoring sequestrectomy. Performing sequestrectomy alone may therefore represent an advantageous alternative to standard microdiscectomy.

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.

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.

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.

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.
