Fixation of Acute Distal Biceps Tendon Ruptures Using Mitek Anchors: A Retrospective Study

PURPOSE OF THIS STUDY: The aim of this study was to evaluate the outcomes of surgical intra-osseous fixation of the distal tendon of the ruptured biceps brachii muscle using Mitek anchors. MATERIALS AND METHODS: Between 2005 and 2011, seven patients underwent unilateral distal biceps tendon repair using Mitek anchors. All patients were men aged between 36 and 47 years. Six patients were assessed by physical examination and use of the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. RESULTS: Surgery was performed within 3 to 17 days of rupture with a mean follow-up of 35 months. Of the six fully completed DASH questionnaires, three patients had a score of 0, and three patients had scores of 5.8, 10 and 10.8, respectively (10.1 is the mean score for the general population). Transient paraesthesias in the lateral antebrachial cutaneous nerve region occurred in two patients and one patient experienced a transient stiffness of the elbow due to scarring of the wound. No major complicatons have occurred. CONCLUSION: The use of Mitek anchors for the re-insertion of the ruptured distal biceps tendon proved to be a safe and effective technique with excellent functional results in our series.
