Ruptures of the proximal biceps tendon in middle-aged patients.

ABSTRACT

Treatment of ruptures of the proximal biceps tendon has been based on clinical observations, with little objective data to substantiate treatment guidelines. Evaluation of 25 patients (all > 40 years of age) at an average of 7.9 years after injury found few objective or subjective differences between those treated nonoperatively and those treated operatively. Only 1 patient (treated nonoperatively) was dissatisfied with the result, and her dissatisfaction was with a cosmetic defect. Objective manual muscle testing and Cybex II (Cybex Corporation, Ronkonkoma, New York) evaluation of 19 patients found no significant differences in supination or elbow flexion strength in the two groups.
