Snapping of the medial head of the triceps and recurrent dislocation of the ulnar nerve. Anatomical and dynamic factors.

摘要: We describe seventeen patients (twenty-two limbs) who had snapping (dislocation) of both the ulnar nerve and medial head triceps over epicondyle. Two (two were seen because painless snapping, four (five pain in aspect elbow, three (three symptoms related to only, six (seven nerve. In addition, was identified incidentally on routine screening five asymptomatic limbs patients, one whom contralateral side. The diagnosis confirmed with magnetic resonance imaging or computerized tomography, both, all but first operative findings confirmatory. Only sufficiently symptomatic be managed operatively. Of these (six lateral transposition excision dislocating addition decompression persistent immediately after a previous transfer performed at another institution for to, well documented dislocation of, nerve; we index procedure correct postoperative which result an unrecognized patient accessory tendon other. One part (without nerve), cubitus varus valgus osteotomy distal humerus that corrected line pull relieved snapping. All operatively excellent (no no nerve, full range motion), average 4.5 years postoperatively. Non-operative treatment provided control from limbs. Snapping side even if it is associated not necessarily caused by alone. Patients have especially those should examined intraoperatively elbow flexion extension so surgeon can certain does snap Failure recognize concurrent persistent, otherwise successful
