This is a retrospective review of 265 consecutive patients with scoliosis treated by posterior spinal fusion (PSF) and 2990 postoperative radiographs at a single institution. ⋯ Only 0.60% of postoperative images (18/2990) demonstrated an implant-related complication, and in the absence of clinical indications, none of these patients required surgical intervention. Isolated postoperative radiographs did not lead to any change in management, and consideration should be given to reviewing current protocols for plain radiographs as a monitoring tool after PSF.

Prospective review of registry data at a single institution from October 2010 to June 2012. ⋯ Depression and anxiety as assessed by ZDS and MSPQ scores were significantly associated with increased preoperative narcotic use, underscoring the importance of thorough psychological and substance use evaluation in patients being evaluated for spine surgery.

The histological comparative study was performed on chordoma and notochordal cell rests (NCRs). ⋯ Our study results supported histological similarity and homology of NCRs coexisting in chordoma and in fetal nucleus pulposus. Brachyury activation probably takes an important role in chordoma tumoregenesis.

Case Reports
Seat belt syndrome with cauda equina syndrome: two unique cases in the same motor vehicle accident.
Case report. ⋯ Two adults in the same car involved in a collision were wearing lap-shoulder belts, and 1 had Denis type A burst fracture at L5 and the other had Denis type B burst fracture at L5. Both developed CES after the accident. Both patients had a good clinical outcome after surgical treatment.

Retrospective study developing diagnostic criteria. ⋯ ExGBB seems to be a far more reliable and accurate to determine anterior cervical fusion. The diagnostic criteria using bone bridging should be different based on the intradiscal materials. With cages in particular, InGBB seems unreliable and ExGBB is necessary to determine anterior cervical fusion.
