Outcomes following resection of intramedullary spinal cord cavernous malformations: a 25-year experience.

Object: The management of intramedullary spinal cord cavernous malformations (CMs) is controversial. At Barrow Neurological Institute, the authors selectively offer surgical treatment for symptomatic spinal cord CMs. The purpose of this paper is to review the clinical outcomes in patients after resection of these lesions based on a single-center experience over a 25-year period.

Return of olfaction after gross total resection of an olfactory groove meningioma: case report.

Patients with olfactory, groove meningiomas may present with anostnia, Surgery in patients with intact olfaction can also lead to anosmia when the olfactory nerves are sacrified. Olfaction can be preserved by using the prerional approach and microsurgical technique. To our knowledge; however, the recovery of olfaction after resection of an olfactory groove meningroma has not been reported.

Biomechanical comparison of anterior versus posterior lumbar threaded interbody fusion cages.

Study Design: Biomechanical flexibility tests were performed in specimens receiving anterior lumbar interbody fixation or posterior lumbar interbody fixation using dual threaded cages.

Objectives: To determine differences in stability between anterior lumbar interbody fixation and posterior lumbar interbody fixation immediately after surgery and after fatigue.

Summary Of Background Data: No direct biomechanical comparison of lumbar fixation with threaded anterior lumbar interbody fixation or posterior lumbar interbody fixation cages has been performed previously.

Anterior lumbar microdiscectomy and interbody fusion for the treatment of recurrent disc herniation.

Objective: To demonstrate the feasibility of anterior lumbar microdiscectomy in patients with recurrent, sequestered lumbar disc herniations.

Methods: Between 1997 and 1999, six patients underwent a muscle-sparing "minilaparotomy" approach and subsequent microscopic anterior lumbar microdiscectomy and fragmentectomy for recurrent lumbar disc extrusions at L5-S1 (n = 4) or L4-L5 (n = 2). A contralateral distraction plug permitted ipsilateral discectomy under microscopic magnification.
