OBJECTIVE We analyzed the epidemiology, preoperative management, operative findings, operative treatment, and postoperative results in a group of 99 patients who sustained 100 injuries to the brachial plexus. METHODS The charts of 100 consecutive surgical patients with brachial plexus injuries were reviewed. RESULTS The patient group comprised 80 males(More)
BACKGROUND The axolemmal distribution and density of voltage-gated sodium channels largely determines the electrical excitability of sprouting neurites. Recent evidence suggests that accumulation of sodium channels at injured axonal tips may be responsible for ectopic axonal hyperexcitability and the resulting abnormal sensory phenomena of pain and(More)
OBJECT The authors report data in 45 surgically treated posterior interosseous nerve (PIN) entrapments or injuries. METHODS Forty-five PIN entrapments or injuries were managed surgically between 1967 and 2004 at Louisiana State University Health Sciences Center (LSUHSC) or Stanford University Medical Center. Patient charts were reviewed retrospectively.(More)
Adult onset of tethered cord syndrome is a rare pathologic entity. Its treatable nature makes early diagnosis and timely surgical intervention important goals. Because of present referral patterns, adult patients with tethered cord syndrome may present initially to their primary care physician. We present a recent representative case of adult-onset tethered(More)
The possible neurotoxic effects of five commonly used steroid agents were examined. Using histologic studies and studies of the microneural circulation, it was found the steroids can indeed cause neurotoxicity. The injection site was critical in effecting injury. Only intrafascicular injection caused damage. The damage produced varied with the agent used.(More)
OBJECTIVE The management of obstetrical brachial plexus injury, often called birth palsy, remains one of the most controversial topics in pediatric neurosurgery. Most birth palsies have acceptable spontaneous recoveries, whereas only a minority require surgical intervention. A selective approach for surgery was used in this Louisiana State University Health(More)
OBJECT This is a retrospective review of 146 surgically treated benign and malignant peripheral non-neural sheath tumors (PNNSTs). Tumor classifications with patient numbers, locations of benign PNNSTs, and surgical techniques and adjunctive treatments are presented. The results of a literature review regarding tumor frequencies are presented. METHODS One(More)
Peripheral nerve trauma frequently affects younger people and may result in significant and long-lasting functional disability. Currently, diagnosis and monitoring of peripheral nerve injury relies on clinical and electrodiagnostic information, supplemented by intraoperative electrophysiological studies. However, in a significant proportion of nerve(More)
OBJECT Outcomes of 1019 brachial plexus lesions in patients who underwent surgery at Louisiana State University Health Sciences Center during a 30-year period are reviewed in this paper to provide management guidelines. METHODS Causes of brachial plexus lesions included 509 stretches/contusions (50%), 161 plexus tumors (16%), 160 thoracic outlet syndromes(More)
OBJECT This is a retrospective review of 397 benign and malignant peripheral neural sheath tumors (PNSTs) that were surgically treated between 1969 and 1999 at the Louisiana State University Health Sciences Center (LSUHSC). The surgical techniques and adjunctive treatments are presented, the tumors are classified with respect to type and prevalence at each(More)
