A retrospective clinical and radiologic evaluation of patients with vertebral osteomyelitis treated via radical debridement and stabilization using titanium mesh cages. ⋯ The use of titanium mesh cages in the treatment of vertebral osteomyelitis effectively reconstructs the anterior column, while adding stability and restoring the sagittal profile. There is no increase in the rate of recurrence or persistence of infection related to the implantation of titanium mesh cages.

Case Reports
Revision and explantation strategies involving the CHARITE lumbar artificial disc replacement.
A large case series of anterior revision surgery in patients who had complications following lumbar total disc replacement with the CHARITE artificial disc. ⋯ Total disc replacement implant revisions occur largely as a result of technical errors in positioning and sizing of the implant. In addition, adherence to strict patient selection criteria will eliminate many cases of implant failure. When necessary, anterior revision surgery can be performed safely when a strategic approach is used.

Numerical techniques were used to study the occipito-atlantoaxial complex. ⋯ The findings from the validation of this newly developed model coincide with the experimental studies so that its application helps contribute to a more comprehensive understanding of the biomechanics of the craniocervical region.

Chronically compressed sciatic nerve segments were transplanted to hemisected spinal cord injured rats. Histologic evaluation and behavior functional outcomes were tested after 6 weeks following surgery. ⋯ Functional recovery after hemisection injury improved significantly in the late postoperative period with transplantation of preconditioned peripheral nerve. Preconditioned grafts also exhibit sustained axonal regeneration at and past the lesional site in histologic analysis. Further investigation with later time points is warranted.
