Comparative Study
Kinematics of cervical total disc replacement adjacent to a two-level, straight versus lordotic fusion.
In vitro biomechanical study. ⋯ TDR placed adjacent to a two-level fusion is subjected to a more challenging biomechanical environment as compared to a stand-alone TDR. An artificial disc used in such a clinical scenario should be able to accommodate the increased moment loads without causing impingement of its endplates or undue wear during the expected life of the prosthesis.

Randomized Controlled Trial Comparative Study
Postoperative surgical site infections in patients undergoing spinal tumor surgery: incidence and risk factors.
We conducted a retrospective, case control study on patients undergoing surgery for spinal tumors. OBJECTIVE.: Our aim was to determine the incidence and to identify risk factors for surgical site infections (SSIs) in patients undergoing surgery for spinal tumors. ⋯ Surgery for spine tumors appears to be associated with a higher incidence of SSI than nontumor spine surgery. Identification of perioperative risk factors will help delineate this subset of patients with high risk for developing SSIs thus potentially allowing perioperative modification for such factors, which may lead to an overall better clinical outcome and patient satisfaction.

Case Reports
Administration of sodium ibandronate in the treatment of complicated giant cell tumor of the spine.
Case study. ⋯ These case studies demonstrate the potential promise of using sodium ibandronate in the treatment of primary and recurrent giant cell tumors of the spine. Furthermore, clinical evaluation should be performed in future studies.

Multicenter Study Comparative Study
The morbidity and mortality of fusions from the thoracic spine to the pelvis in the adult population.
A retrospective analysis. ⋯ Complex spine reconstruction involving fusions from the thoracic spine to the pelvis continues to be a high-risk procedure in spite of more advanced surgical and perioperative techniques.

Comparative Study
One, two-, and three-level instrumented posterolateral fusion of the lumbar spine with a local bone graft: a prospective study with a 2-year follow-up.
Prospective trial. ⋯ If one- and two-level posterolateral fusion were performed, the local bone graft technique provides a good and uniform bone union rate; however, for three-level fusion poor results were obtained because of an insufficient amount of local bone.
