MR imaging of peripheral nerves has been described in relation to abnormalities such as nerve injury, entrapment, and neoplasm. Neuroma formation is a known response to peripheral nerve injury, and here we correlate the MRN appearance of postinjury neuroma formation with intraoperative findings. We also present the MR imaging features of surgical treatment(More)
BACKGROUND Although distal tibial nerve compression is well recognized, proximal tibial nerve compression remains a rarely recognized clinical condition. This report defines the presentation, diagnosis, surgical decompression technique, and clinical outcome of neurolysis of the tibial nerve at this soleal sling compression site. METHODS Forty-nine(More)
This is the first multicenter prospective study of outcomes of tibial neurolysis in diabetics with neuropathy and chronic compression of the tibial nerve in the tarsal tunnels. A total of 38 surgeons enrolled 628 patients using the same technique for diagnosis of compression, neurolysis of four medial ankle tunnels, and objective outcomes: ulceration,(More)
Rates of synthesis and degradation of heart protein were measured during 30 or 60 min of myocardial ischemia and during the 30 or 60 min following these ischemic periods. During ischemia, rates of protein synthesis and degradation were reduced. Resumption of control rates of coronary flow after 30 min of ischemia resulted in complete restoration of creatine(More)
BACKGROUND Intercostal neuralgia due to surgical injury of the intercostal nerve is difficult to treat. No treatment modality has given effective pain relief. Experience with other painful neuromas has demonstrated that neuroma resection and muscle implantation has been effective in the upper and lower extremities. This approach was applied to patients with(More)
During reperfusion, functional and metabolic recovery of the isolated working rat heart from one hour of ischemia was best in hearts selectively cooled at the onset of the ischemic interval by perfusion with 5 to 10 ml. of 10 degrees C. or 15 degrees C. Krebs-Henseleit buffer. Hearts similarly perfused at 4 degrees C., 20 degrees C. recovered significantly(More)
A 3-cm gap in the ulnar nerve at the elbow in a subhuman primate was the first model of nerve regeneration across a polyglycolic, bioabsorbable conduit. When a prospective trial was begun in humans, the first clinically available bioabsorbable conduit, the Neurotube, was utilized to reconstruct sensory nerves, but motor nerve injuries were not included.(More)
BACKGROUND The sympathetic innervation of the hand was demonstrated using formaldehyde staining techniques in the 1990s and provides a basis for both medical (botulinum toxin type A) and surgical (sympathectomy) therapeutic approaches. This research investigates the sympathetic innervation of the human foot using tyrosine hydroxylase immunohistochemistry.(More)
The clinical findings in this series of 22 cases of subclavian steal syndrome showed a predominance of men (13:9), a mean age of 51 years, and a predominance of left subclavian artery obstruction. There was a blood pressure differential of more than 20 mm Hg and diminished pulses ipsilaterally in most. Main indications for surgical repair were transient(More)
