Clinical Trial
Low fusion rate after L5-S1 laparoscopic anterior lumbar interbody fusion using twin stand-alone carbon fiber cages.
Prospective study of a cohort of patients who underwent L5-S1 laparoscopic anterior lumbar interbody fusion. ⋯ Two years after endoscopic L5-S1 anterior lumbar interbody fusion using twin stand-alone laparoscopic carbon-fiber cages, the fusion rate was unacceptably low. However, the clinical outcomes of these patients were significantly improved compared with their preoperative status.

An analysis of lateral radiographs in the upright, flexion-extension position. ⋯ The results suggest that alterations in the static alignment of the cervical curvature cause alterations in the dynamic kinematics of the cervical spine during cervical flexion-extension. This information should aid in the interpretation of kinematic studies of the cervical spine.

A case-control retrospective analysis comparing patients who developed a postoperative spinal epidural hematoma with patients who did not develop this complication. ⋯ Patients who require multilevel lumbar procedures and/or have a preoperative coagulopathy are at a significantly higher risk for developing a postoperative epidural hematoma.

Case Reports
Multimodality management of a giant cell tumor arising in the proximal sacrum: case report.
Descriptive. ⋯ A novel multimodality approach, consisting of resection, controlled cryosurgery, and a unique lumbopelvic reconstruction, was safe and successful in managing a challenging proximal sacral giant cell tumor. Twenty months after surgery the patient has excellent bowel and bladder control, no tumor recurrence, and functional ambulation without a brace or pain.

Clinical Trial
Predictors of neurologic recovery in acute central cervical cord injury with only upper extremity impairment.
A prospective study of 22 patients with the syndrome of acute central cervical spinal cord injury with motor and sensory impairment involving only upper extremities (ACCSCI-U) was done from admission to the 2-year follow-up. ⋯ In patients with ACCSCI-U, a favorable neurologic prognosis can be predicted following nonsurgical treatment. Most recovery occurred by 6 weeks, and patients with severe initial neurologic damage and old age had poorer recovery. Touch and pin sensation recovered at the same rate, whereas motor recovered more quickly. The absence of abnormal MRI signal intensity in the spinal cord and a good early neurologic improvement were the significant predictors of long-term improvement in neurologic function.
