Functional outcome of complete distal biceps tendon repair following noninvasive operative management in the west of Iran

Abstract

Background and Objectives: Avulsion of the distal biceps tendon insertion from the radial tuberosity is rare. It is an opportunity for a double-incision surgical technique for repairing a complete tear of the distal biceps tendon. The aim of this study is to evaluate the double-incision technique with regard to full functional restoration, complication rate, and safety. Materials and Methods: A retrospective review of consecutive complete biceps tendon repair was performed at one institution over a 6-year period. Thirty-two patients met the inclusion criteria and 28 were available for follow-up which included subjective assessment, physical examination, and strength testing. The mean age of patients was 40 ± 28 years (ranging from 25 to 71 years). Modified two-incision surgical approach (Boyd and Anderson) was performed for all the patients. Functional outcome after repairs was measured by physical examination, range of motion measurements using a goniometer and radiographic follow-up, as well as isokinetic tests and Disability of the Arm, Shoulder, and Hand scores. Furthermore, the average patient satisfaction rating on a Likert scale associated with complications was documented. Results: There were no statistically significant differences in regard to flexion strength or endurance and supination strength or endurance between the injured and uninjured arm in each patient. The overall incidence of complications was 7.2%. The average patient satisfaction rating was 9.6. Conclusion: The modified Boyd–Anderson two-incision produced adequate and full functional restoration of strength with a low complication rate. This technique is safe to perform by a surgeon.
