The case report of a 60-year-old man with late onset back pain after lumbar spine fusion is presented. ⋯ The pedicle is the weakest point in the neural arch after posterolateral fusion. Although movement continues at the level of the disc space anteriorly, the pedicle is susceptible to fracture. Pedicle fracture is a rare late complication of posterolateral lumbar spine fusion.

A systematic review of the literature. ⋯ Caution is needed when drawing a valid conclusion on the efficacy of conservative treatments in patients with whiplash injury. It appears that "rest makes rusty," whereas active interventions have a tendency to be more effective in patients with whiplash injury.

Randomized Controlled Trial Clinical Trial
Early complications of high-dose methylprednisolone sodium succinate treatment in the follow-up of acute cervical spinal cord injury.
A prospective, randomized, and double-blind study comparing high-dose methylprednisolone sodium succinate (MPSS) with placebo, in the treatment of patients with acute cervical spinal cord injury. ⋯ Aged patients with cervical spinal injury may be more likely to have pulmonary side effects (P = 0.029) after high-dose therapy with MPSS and thus deserve special care.

A case series of 12 patients who underwent spine surgery in an intraoperative magnetic resonance imager (IMRI). ⋯ The IMRI provided accurate and rapid localization in all cases and confirmed the adequacy of decompression in the majority of cases. Future applications of the IMRI to spine surgery may include intraoperative guidance for resection of spine and spinal cord tumors and trajectory planning for spinal endoscopy or screw fixation.
