Accuracy of intraoperative computed tomography-based navigation for placement of percutaneous pedicle screws.

MISS techniques have gained recent popularity. The proposed benefits of these techniques include reduced tissue trauma, reduced blood loss, less perioperative pain, and a quicker recovery and return to normal activities. The purpose of this study was to evaluate the accuracy of intraoperative computed tomography (CT)-based navigation for placement of percutaneous pedicle screws in a cadaveric model.

Estimating the effective radiation dose imparted to patients by intraoperative cone-beam computed tomography in thoracolumbar spinal surgery.

Study Design: Observational.

Objective: To estimate the radiation dose imparted to patients during typical thoracolumbar spinal surgical scenarios.

Summary Of Background Data: Minimally invasive techniques continue to become more common in spine surgery.

Does intraoperative neurophysiological monitoring have predictive value for functional recovery following spinal cord injury? A case report.

To present a case report of a patient with an ASIA B spinal cord injury with partially intact baseline IONM who made a complete functional recovery postoperatively. A thirty-three year old male presented after a motor vehicle accident. Imaging studies revealed a C4-C5 bilateral facet dislocation.

Is there a difference between simultaneous or staged decompressions for combined cervical and lumbar stenosis?

Study Design: We evaluated 43 patients diagnosed with tandem spinal stenosis (TSS) from 1999 to 2005 in an academic hospital.

Objective: The purpose of this study is to compare outcomes after simultaneous decompression of the cervical and lumbar spine versus staged operations.

Summary Of Background Data: TSS is a rare degenerative disease affecting multiple spinal levels with limited research describing operative management.

Revision strategy for posterior extrusion of the CHARITÉ polyethylene core.

Study Design: This is a case report of a posterior extrusion of the polyethylene core from a CHARITÉ arthroplasty. This is the first reported case of posterior dislocation of the polyethylene and the revision strategies used to correct this problem.

Objective: To report a novel failure mechanism and revision strategy for CHARITÉ total disc arthroplasty (TDA).
