Entrapment neuropathies of the median nerve at and above the elbow.
Three surgically verified cases of median nerve entrapment at and above the elbow are reported: one involved a compression of the nerve beneath the Struthers ligament in absence of supracondylar bony spur, and two concerned a compression beneath the lacertus fibrosus bicipitis (aponeurosis musculi bicipitalis brachii). Of the two latter cases, the first entrapment was caused by a hematome and the second the nerve was found to be entrapped between the lactertus and an underlying hypertrophic brachial muscle. The compression mechanisms and clinical and electromyographic findings are presented.
