A genetic association study to comprehensively investigate variations of neurotrophin 3 (NTF3) gene polymorphisms in a Chinese Han population. ⋯ The NTF3 gene polymorphisms are not associated with the occurrence of AIS, but the promoter polymorphism (rs11063714) is associated with the curve severity, implicating an alleviating role of NTF3 in the curve progression of AIS. In addition, the promoter polymorphism is also associated with brace responsiveness. These findings indicated that NTF3 gene might be a disease-modifying gene of AIS.

Retrospective case series. ⋯ In this series, en bloc resection, the absence of metastasis, low-grade tumors, and negative margins were associated with improved overall survival. The aggressive use of sophisticated surgical and radiation techniques appears to confer an advantage to patients, decreasing local recurrence and increasing overall survival, even following incomplete surgical resection.

Retrospective case-control study. ⋯ Spinal fusion for scoliosis in RS can give a satisfactory technical result, but a high rate of early postoperative medical problems should be anticipated.

Prospective study of 212 patients with groin pain but without low back pain. ⋯ In the current study, we diagnosed discogenic groin pain, using magnetic resonance imaging, infiltration of lidocaine into the hip joint, pain provocation on discography, pain relief by anesthetic discoblock, and lumbar surgery. It is important to consider the existence of discogenic groin pain if patients do not show low back pain.

Controlled laboratory study. ⋯ PLIF using expandable lumbar interbody cage requires pedicle screw fixation.
