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)
Over a 22-year period, operations were performed on 263 patients for 288 primary benign tumors of major peripheral nerves. The tumors included 85 schwannomas, 197 neurofibromas, and six plexiform neurofibromas. Total removal was achieved in 83 of the 85 schwannomas, and 76 of these patients were available for follow-up evaluation. Motor function either(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)
A 54-year-old man experienced a right occipital headache accompanied by a roaring sound, nausea, vomiting, right facial weakness, and stiff neck. Vertebral angiography revealed an aneurysm of the right anterior inferior cerebellar artery (AICA) at the internal acoustic meatus which was later excised with favorable results. The literature is reviewed;(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)
OBJECTIVE This is a retrospective review of 33 charts of patients with ilioinguinal and iliohypogastric neuralgias who underwent a neurectomy at Louisiana State University Health Sciences Center between 1967 and 2000. Operations associated with neuralgias and postoperative pain outcomes were analyzed. METHODS There were 23 ilioinguinal and 10 combined(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)
