Retrospective cohort study and systematic literature review. ⋯ The return-to-work rates for a universal no-fault compensation system are higher than those under WC cover, and are compatible with non-WC cases. This suggests that the features of WC may contribute to the inferior return-to-work rates.
-
Retrospective cohort study of consecutive patients. ⋯ Intrawound vancomycin may be beneficial for nontumor spine patients who undergo open posterior instrumented surgeries, but may not for those with spinal tumors. The poor physical health status, major surgical trauma, and tumor-related adjuvant treatments of patients with spinal tumor may contribute to this disparity.

A biomechanical study comparing arthroplasty with fusion using human cadaveric C2-T1 spines. ⋯ Cervical disc arthroplasty with both the BRYAN and PRESTIGE LP discs not only preserved the motion at the operated level, but also maintained the normal motion at the adjacent levels. Under simulated physiologic loading, the motion patterns of the spine with the BRYAN or PRESTIGE LP disc were very similar and were closer than fusion to the intact motion pattern. An adjacent segment disc replacement is biomechanically favorable to a fusion in the presence of a pre-existing fusion.

Randomized Controlled Trial
Factors affecting the outcome of surgical versus nonsurgical treatment of cervical radiculopathy - a randomized, controlled study.
Prospective randomized controlled trial. ⋯ In this prospective, randomized study of patients with cervical radiculopathy, short duration of pain, female sex, low health quality, high levels of anxiety due to neck/arm pain, low self-efficacy, and a high level of distress before treatment were associated with better outcome from surgery. No factors were found to be associated with better outcome from physiotherapy alone.

A genetic association study of leptin receptor (LEPR) gene with adolescent idiopathic scoliosis (AIS) in the Chinese Han population. ⋯ Polymorphism of rs2767485 in LEPR gene is associated with the occurrence of AIS, suggesting LEPR is a predisposition gene.
