Adults And Children

The outcome of 38 median and ulnar nerve injuries at the wrist in 15 adults and 15 children were studied with a follow-up of at least 1 year. Each patient was assessed clinically and with nerve conduction studies. The results confirm a markedly superior sensory recovery in children. However the children had persistent motor deficiencies. This difference in the clinical results of adults and children was not reflected in the nerve conduction results which were similar in both groups.

Anatomy And Physiology

Repetitive stimulation is a technique that evaluates the function of the neuromuscular junction. It is important not only in the detection, clarification, and follow-up of neuromuscular junction diseases, but also in excluding these disorders in patients with symptoms of fatigue, vague weakness, diplopia, ptosis, and malaise, or with objective weakness of uncertain origin. The technique requires knowledge of the physiology and pathophysiology of neuromuscular transmission and the basic techniques of nerve conduction studies. This chapter includes a brief review of the anatomy and physiology of the neuromuscular junction as it applies to repetitive stimulation, a detailed discussion of the technique, the pitfalls that can occur if not carried out correctly, criteria used to classify the results as normal or abnormal, the patterns of abnormalities that can be seen, and the clinical correlation of those abnormalities with the various different disorders of neuromuscular transmission.

Hand Symptoms

A retrospective study of 15 diabetic patients (20 hands), who underwent carpal tunnel release, was performed to determine the outcome. All patients had a minimum of 18 months of follow-up. Outcome was considered excellent if there was complete resolution of symptoms and this occurred in 35% of the treated hands. Eight hands (40%) had a good outcome with significant improvement of pre-operative symptoms. Outcome was considered poor when symptoms were minimally improved, unchanged, or worse after surgery and this occurred in 25% of treated hands. All hands with a poor final result had either no electrodiagnostic evidence of localized compression or only mild compression in pre-operative nerve conduction studies. It was postulated that the contribution of localized compression to pre-operative hand symptoms was less than the contribution of peripheral neuropathy in these hands.

✓ After a few reports on end-to-side nerve repair at the beginning of the last century, the technique was put aside until its recent reintroduction. The authors present their results in three patients with median nerve defects that were between 15 and 22 cm long and treated using end-to-side median-to-ulnar neurorrhaphy through an epineurial window. The follow-up times were between 32 and 38 months. Sensory evaluation involved superficial touch, pinprick, and two-point discrimination tests. Motor evaluation was completed by assessing the presence of opposition and by palpating the abductor pollicis brevis muscle. Sensory recovery was observed in all patients in the median nerve dermatome, and motor recovery was absent, except in Case 1. End-to-side nerve repair can be a viable alternative to nerve grafting in patients with long gaps between the ends of the injured nerve.

Tunnel Syndrome

Anterior transposition of the ulnar nerve is a widely used treatment for cubital tunnel syndrome, but neurolysis performed at the time of surgery may impair the blood supply to the ulnar nerve. This study compared the results of intramuscular anterior transposition of the ulnar nerve with or without preserving the extrinsic vessels of the ulnar nerve in 35 patients. The postoperative nerve conduction velocity and the clinical results were better in the group in which the extrinsic vessels were presented.

Tunnel Syndrome

Background: Cubital tunnel syndrome is a common compressive neuropathy of the upper extremity. The anconeus epitrochlearis muscle is an unusual but occasional contributor. We review our experience with this anomalous muscle in elbows with cubital tunnel syndrome. Methods: We retrospectively reviewed charts of 13 patients noted to have an anconeus epitrochlearis muscle associated with cubital tunnel syndrome. Results: Ten patients had unilateral ulnar neuropathy supported by nerve conduction studies. Three had bilateral cubital tunnel syndrome symptoms with 1 of those having normal nerve conduction studies for both elbows. Eight elbows were treated with myotomy of the anconeus epitrochlearis muscle and submuscular transposition of the ulnar nerve. The other 8 elbows were treated with myotomy of the anconeus epitrochlearis muscle and in situ decompression of the ulnar nerve only. All but 1 patient had either clinical resolution or improvement of symptoms at follow-up ranging from 2 weeks to 1 year after surgery. The 1 patient who had persistent symptoms had received myotomy and in situ decompression of the ulnar nerve only. Conclusions: An anomalous anconeus epitrochlearis occasionally results in compression of the ulnar nerve but is usually an incidental finding. Its contribution to compression neuropathy can be tested intraoperatively by passively ranging the elbow while observing the change in vector and tension of its muscle fibers over the ulnar nerve. Regardless of findings, we recommend myotomy of the muscle and in situ decompression of the ulnar nerve. Submuscular transposition of the ulnar nerve may be necessary if there is subluxation.

Median Neuropathy

The incidence of musculoskeletal injuries among musicians is well documented. The purpose of this study was to describe the neural status of the median and ulnar nerves in young adult violinists. Twenty volunteer violinists were recruited from the Belmont University and the Vanderbilt University Blair School of Music Orchestras (age 18-30 years). The subjects completed a history form and underwent a physical examination. The electrophysiologic status of the median and ulnar nerves in both upper extremities was then evaluated using sensory and motor nerve conduction studies (NCSs). Upon completion of the NCSs, educational materials to prevent upper extremity cumulative trauma disorders were distributed to the subjects. In these subjects, the history and subjective examination were largely noncontributory of upper extremity neuropathies. Their physical examinations were also not diagnostic of upper extremity neuropathies. All subjects’ median and ulnar NCSs were normal when compared with a chart of normal values. However, when comparison studies between the median and ulnar NCSs in the same extremity were performed, seven subjects showed differences in their distal motor latencies (>1.0 msec) or distal sensory latencies (>0.5 msec) that could be suggestive of early median neuropathy at or distal to the wrist. In this descriptive study, 20 young adult violinists had no subjective findings of median or ulnar neuropathy, had normal physical examinations of the neck and both upper extremities, and had normal median and ulnar NCSs when compared with a chart of normal values. However, when comparison NCSs between the median and ulnar nerve in the same extremity were performed, seven violinists were found to have NCS values suggestive of early median neuropathy at or distal to the wrist. In this population of 20 young adult violinists, seven musicians were found to have electrophysiologic findings suggestive of early median neuropathy at or distal to the wrist.
