Plasma glyceryl trinitrate (GTN) concentration was studied in 12 volunteers producing gun powder. Serial blood samples were obtained from the cubital vein before and during work at two sites of production; high concentrations of GTN were detected in the plasma. Control specimens from a femoral vein contained much less GTN, indicating that blood in the cubital vein was enriched by dermally absor...

The aim of the present study was to investigate a new clinical classification of cubital tunnel syndrome that provides an improved basis for the clinical diagnosis and treatment of the disease. Retrospective analysis was performed on 341 patients with cubital tunnel syndrome. Based on the etiology, signs and symptoms, neurophysiological tests and computed tomography (CT) imaging, a new clinical...

Cubital tunnel syndrome is the second most common peripheral nerve entrapment syndrome in the human body. It is the cause of considerable pain and disability for patients. When appropriately diagnosed, this condition may be treated by both conservative and operative means. In this review, the current thinking on this important and common condition is discussed The recent literature on cubital t...

The overall success rate of surgical interventions for cubital tunnel syndrome is reported to be within 80% to 90% (Szabo, 1999). The discussion, however, whether to perform in situ nerve decompression or anterior transposition continues. In this paper, we present the results of our endoscopic approach to in situ cubital tunnel release, its rationale, clinical and anatomical indications and a d...

Lesions of the ulnar nerve are the most common causes of paralysis of a peripheral nerve.1,2 The cubital tunnel (or sulcus ulnaris) syndrome is the second most frequent compression syndrome of the upper extremities after the carpal tunnel syndrome.3,4 We report our findings in a patient who suffered from cubital tunnel syndrome and underwent subcutaneous anterior transposition, a surgical proce...

The purpose of the present study was to describe a new minimally invasive surgical technique for decompression of the ulnar nerve at the elbow for treatment of cubital tunnel syndrome. Four patients underwent surgical treatment for cubital tunnel syndrome. Preoperative clinical states were classified by using the McGowan grading system and the postoperative states were recorded by using the Wil...

BACKGROUND Cubital tunnel syndrome (CUT) is the second most common peripheral neuropathy with an annual incidence of 24.7 per 100 000, affecting nearly twice as many men as women. With increasing focus on cost-effectiveness and cost-containment in medicine, a critical understanding of utilization of health care resources for open and endoscopic approaches for cubital tunnel release is of value....

BACKGROUND Neuropsychological effects of considerably low levels of lead exposure are observed in children, and a reliable and possibly painless technique that can detect such levels is required for the assessment of such exposure. We examined whether the blood lead (BPb) concentrations obtained from the earlobe were as valid and useful as those from the median cubital vein. METHODS Paired bl...

BACKGROUND Severe cases of cubital tunnel syndrome do not always result in functional recovery after surgical decompression of the ulnar nerve. A combined operation of tendon transfer to restore index finger abduction and decompression of the ulnar nerve was performed for patients with severe cubital tunnel syndrome who required powerful pinch strength and whose preoperative compound muscle act...

Variations of the anterior transposition of the ulnar nerve for cubital tunnel syndrome include subcutaneous, submuscular, intramuscular, and subfascial methods. We introduce a modification of subfascial transposition, which is designed to facilitate nerve gliding by wrapping the nerve with fascia. Twenty patients with wrapping surgery following the diagnosis of cubital tunnel syndrome were rev...
