Results of treatment of unstable thoracolumbar burst fractures using pedicle instrumentation with and without fracture-level screws.
Two different techniques of short-segment instrumentation, with and without a pedicle screw at the fracture level, were compared in thoracolumbar burst fractures in neurologically intact (ASIA-E) patients. The sagittal index, kyphosis angle (Cobb), canal compromise ratio, and compression ratio of the anterior vertebral height were analyzed. ⋯ Short-segment stabilization in thoracolumbar burst fractures with additional screws at the level of the fracture results in an improved kyphosis correction, sagittal index, and compression ratio of the anterior vertebral height. However, long-term follow-up is needed to determine the clinical significance of these findings.

Intraoperative neurophysiological monitoring during resection of intradural extramedullary spinal cord tumors: experience with 100 cases.
Intradural-extramedullary spinal cord tumor surgery is common. Unlike intramedullary spinal cord tumor surgery, where intraoperative neurophysiological monitoring (IONM) has been described extensively, the application of IONM has not been described in this context, and its relevance has not been investigated. ⋯ IONM is feasible and useful in the context of intradural-extramedullary spinal cord surgery for identifying iatrogenic injury to the spinal cord.

Peroneal intraneural ganglion cysts at the fibular neck: the layered "U" surgical approach to the articular branch and superior tibiofibular joint.
Intraneural ganglia most commonly occur within the peroneal nerve near the fibular neck. Disconnection of the articular branch is required in their treatment. Surgical intervention can be challenging because of unfamiliarity with the region or scarring from previous surgery. ⋯ This pathoanatomic approach provides direct and safe exposure of the articular branch of the common peroneal nerve.
