Cervical pedicle screw placement using the "key slot technique": the feasibility and learning curve.
A retrospective study. ⋯ We performed CPS placement using the KS technique and with 90% correct position without clinical complications. After the learning curve, the incidence was 2.7%. This technique could be considered relatively concrete and safe modification of conventional technique with minimal bone loss.

Cost effectiveness analysis of graft options in spinal fusion surgery using a Markov model.
Statistical decision model. ⋯ RhBMP is the most cost-effective graft option for L4-L5 fusion for degenerative spondylolisthesis largely due to the reduced rate of revision spine surgery. The increased upfront cost and list of complications associated with RhBMP is offset by the reduced rate of revision surgery.
