Comparative Study
Intradiscal thermal therapy does not stimulate biologic remodeling in an in vivo sheep model.
Thermal energy was delivered in vivo to ovine cervical discs and the postheating response was monitored over time. ⋯ While a high temperature thermal protocol had a detrimental effect on the disc, the effects of low temperature treatment were relatively minor. Thermal therapy did not stimulate significant biologic remodeling. Future studies should focus on the effects of low-dose therapy on tissue innervation and pro-inflammatory factor production.

A retrospective review of all cases of high-grade spondylolisthesis treated by 1 surgeon between the years 1991 and 2003. ⋯ These data suggest that a posterior instrumented reduction and fusion of high-grade spondylolisthesis without decompression of the neural elements can be accomplished with acceptable radiographic and clinical results.

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
Radiographic analysis of intervertebral separation with a 0 degrees and 30 degrees rope angle using the Saunders cervical traction device.
Radiographic analysis of cervical intervertebral separation, (IVS) while using the Saunders Cervical Traction Device (SCTD) (Chattanooga Corp., Chattanooga, TN) on a healthy population. ⋯ The research findings may have treatment implications when applying cervical traction with the SCTD. Further research using subjects with cervical nerve root compression will need to be conducted to substantiate clinical outcomes.

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.
