Longitudinal study with a 6-month follow-up. ⋯ Work-related factors that were associated with the occurrence of musculoskeletal symptoms were quite similar to those associated with health care use and sick leave. However, for LBP, older age and living alone, and, for neck/upper extremity symptoms, living alone and being female more strongly determined whether subjects with these complaints took sick leave. These results imply that prevention strategies aimed at minimizing the risks of the occurrence of work-related musculoskeletal symptoms and prevention programs aimed at reducing sick leave may need to emphasize different sets of risk factors.

Retrospective clinical and radiographic review. ⋯ Traditional anterior/posterior fusion technique provides no additional improvement in radiographic outcome compared to posterior-only surgery for adolescent hyperkyphosis. Preliminary anterior release and fusion is no longer performed when correcting this deformity with a posterior column shortening procedure and threaded rod compression instrumentation.

Clinical Trial
Anatomic considerations for the pedicle screw placement in the first cervical vertebra.
Anatomic bony measurements were manually performed on 50 dry atlantoaxial vertebral complexes with an electronic digital caliper, and a reliable landmark for insertion of a pedicle screw in C1 vertebra was described and evaluated. ⋯ The heights of the C1 pedicle, the posterior arch under the groove and the posterior lamina at the screw entry point are the major determinants for the possibility of placing pedicle screws in C1 of a given patient. This study indicates that it is feasible to place a 3.5-mm pedicle screw safely in C1 in most patients, and the lateral mass of C2 is a reliable anatomic landmark that can be easily identified to help the surgeon determine the optimal screw entry portal conveniently during surgery.

Retrospective report of five surgical cases and review of the literature. ⋯ The authors' one-stage anterior procedure employing their TARP for the surgical treatment of irreducible anterior atlantoaxial subluxation was effective in these five cases. This method was able to avoid the need for interval traction and/or a second stage posterior instrumentation and fusion procedure.

Randomized Controlled Trial Comparative Study
The effect of autologous fibrin tissue adhesive on postoperative cerebrospinal fluid leak in spinal cord surgery: a randomized controlled trial.
A prospective randomized study evaluating the efficacy of autologous fibrin tissue adhesive for decreasing postoperative cerebrospinal fluid (CSF) leak in spinal cord surgery. ⋯ We used autologous fibrin tissue adhesive as a new sealant after dural closure instead of commercial fibrin tissue adhesive. No definitive CSF leak was observed, and the volume of drainage fluid was significantly lower in the group with autologous fibrin tissue adhesive than that in the group without fibrin tissue adhesive. The use of autologous fibrin tissue adhesive was superior to that of commercial fibrin tissue adhesive in cost.
