One case is reported in which a failed anterior fusion for Grade 4 spondylolisthesis was treated with a vascularized fibular strut graft using a posterior approach. ⋯ A vascularized fibular strut graft is a feasible alternative in the treatment of severe spondylolisthesis. No complications were encountered in the involved patient. Future application may include salvage reconstruction of failed arthrodesis or in individuals with systemic conditions that may impair graft incorporation using more standard techniques.

Comparative Study
Disc herniation-related back pain impairs feed-forward control of paraspinal muscles.
A comparative study of lumbar paraspinal muscle reflexes during sudden upper limb loading in healthy control subjects and patients with sciatica. ⋯ The results provide evidence for impaired feed-forward control of lumbar muscles in patients with sciatica.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
A multicenter, prospective, randomized trial evaluating a new hemostatic agent for spinal surgery.
A prospective, randomized trial comparing Proceed, a gelatin-based hemostatic sealant (treatment), with Gelfoam-thrombin (control) in stopping intraoperative bleeding during spinal surgery. ⋯ A significantly larger number of bleeding sites had achieved hemostasis with Proceed than with Gelfoam-thrombin at 1, 2, and 3 minutes after application. Proceed was as safe as Gelfoam-thrombin when used for hemostasis during spinal surgery procedures.

A retrospective study was conducted to investigate 21 patients found during spinal surgery to have paraspinal masses of dystrophic calcification (tumoral calcinosis). ⋯ Awareness of tumoral calcinosis of the spine may prevent unwarranted diagnoses of a more serious lesion in patients with characteristic magnetic resonance imaging changes. Also, this awareness may prevent pathologists from interpreting lesional tissue as nondiagnostic when other diagnoses are suspected clinically. This process may be a manifestation of degenerative spinal disease that has become so dominant that the underlying processes are obscured.

A case report is presented. ⋯ With improvements in advanced trauma life support, the number of patients with atlanto-occipital dislocation admitted to hospital alive is increasing, so this particular lesion must be kept in mind. When the patient survives the accident, the long-term prognosis is quite good, with a high rate of recovery after initial neurologic deficits.
