Review Comparative Study
Rehabilitation following first-time lumbar disc surgery: a systematic review within the framework of the cochrane collaboration.
A systematic review of randomized controlled trials. ⋯ There is no evidence that patients need to have their activities restricted after first-time lumbar disc surgery. There is strong evidence for intensive exercise programs (at least if started about 4-6 weeks postoperative) and no evidence they increase the reoperation rate. It is unclear what the exact content of postsurgery rehabilitation should be. Moreover, there are no studies that investigated whether active rehabilitation programs should start immediately postsurgery or possibly 4 to 6 weeks later.

A case report of anterior screw fixation from the axis to the occiput is described, as is the surgical technique. The pertinent anatomy is described with a radiographic assessment of the feasibility, safety, and general applicability of this technique. ⋯ This new technique of anterior fixation of the atlas to the occiput is feasible and safe if meticulous surgical planning is performed.

A retrospective and prospective cohort. ⋯ It is recommended that an occupational management approach, in comparison with standard care or early intervention, be considered for management of occupational injuries.

This article examines the application of Americans with Disabilities Act requirements to professional associations like physician practice groups. In general, employers with 15 or more full-time employees must comply with the Act. However, the definition of an employee is sometimes unclear, especially as applied to business entities commonly used by physician practice groups. ⋯ Similar questions arise for popular business entities, such as Limited Liability Companies and Limited Liability Partnerships. This article discusses the nature of the business forms commonly used by physician practice groups and how their characteristics impact employee status for Americans with Disabilities Act coverage. It then suggests that examination is useful beyond business formation characteristics to the purpose of the Americans with Disabilities Act and other employment antidiscrimination statutes.

Comparative Study
Anterior occiput to axis screw fixation: part II: a biomechanical comparison with posterior fixation techniques.
This biomechanical study used flexibility testing on fresh-frozen human cadaveric specimens (occiput to C3) and compared the range of motion and neutral zone for three occipitocervical fixation techniques. ⋯ The anterior screw fixation technique was as effective as a posterior plate with transarticular screws in stabilizing between the occiput and C2 in axial rotation and lateral bending. In extension and flexion, the anterior screw technique was not as effective as a posterior plate with transarticular screws in providing stability.
