An end-result study was made of 16 cases of avulsion of the insertion of the biceps brachii tendon. The follow-up period spanned one to 25 years post-treatment (average, eight years). Fourteen of the 16 cases included in the study were acute cases with primary repair and reinsertion of the biceps tendon into the area of the radial tuberosity. One case, with the loss of function of the biceps muscle secondary to temporary paralysis of the musculocutaneous nerve, was explored. The tendon was found intact and did not require repair. The sixteenth case was included for comparison of a patient who chose to forgo surgical treatment. One surgical procedure, a modification of Bunnell's technique, was used in treating all patients from 1954 to 1977. The surgically repaired biceps showed various amounts of residual impairment, ranging from negligible to limited restriction of preinjury activities. The treatment successfully returned 14 patients to their previous occupations and activities. The one case not surgically treated of the ten work-related injuries resulted in continuing disability compensation based on no greater than 20% of the entire extremity. This end-result study substantiates the positive results of this surgical technique, presents modifications of the surgical repair procedures, and allows for a similar long-range study of other treatment techniques. The evaluation of treatment methods is easily attainable by low technological clinical methods.
