Case Reports
Segmental spinal dysgenesis: case report of a 50-year follow-up after surgery at age 3 years: case report.
Case report with ultra long-term follow-up. ⋯ Arthrodesis at age 3 years provided an optimal ultra long-term follow-up.

Exploratory experimental design. ⋯ Coupled movements are a natural part of cervical motion together with primary movements and follow specific patterns in subjects with no symptoms of neck disorders. Our study shows that cervical motion alters throughout life according to specific patterns but with individual variations.

Comparative Study Controlled Clinical Trial
Head repositioning accuracy in patients with whiplash-associated disorders.
Controlled study, measuring head repositioning error (HRE) using an electrogoniometric device. ⋯ In patients with WAD, range of motion and head repositioning accuracy were reduced. However, the differences were small. Vision suppression and task type influenced HRE.

A C1-C2 operation by the transoral approach was simulated to study the anatomic stratification, various structures, and adjacent relationships. The anatomic parameters in relation to transoral atlantoaxial reduction plate (TARP) internal fixation were measured. ⋯ An atlantoaxial surgery through transoral approach is safe and feasible. This approach is suitable for an anterior TARP internal fixation, and the design of the internal fixation system should be based on the above anatomic data.

Comparative Study
Postlaminectomy kyphosis in the skeletally immature achondroplast.
Retrospective review. ⋯ Skeletally immature achondroplasts are at high risk for developing postlaminectomy thoracolumbar kyphoses. Therefore, concurrent spinal fusion is indicated in skeletally immature achondroplasts who undergo thoracolumbar laminectomies of at least 5 levels.
