Low incidence of tendon rerupture after distal biceps repair by cortical button and interference screw

Background e of cortical suspensory fixation in conjunction with an interference screw to treat distal biceps ruptures has yielded favorable results. However, literature examining the incidence of fixation failure in a large consecutive series of patients treated with this technique is lacking. s ospective review of electronic medical records identified 170 distal biceps ruptures in 168 consecutive patients (164 men and 4 women) treated using a cortical button in conjunction with an interference screw. The study group was an average age of 48 years (range, 20-71 years). Records were reviewed from the time of the initial clinic visit to the most recent follow-up. Early failures were defined as those that occurred within 12 weeks of the index procedure. Failed repair was defined as tendon defect, deformity, or significant weakness in supination. s rly incidence of failure was 1.2%, with 2 of the fixations meeting the criteria for failure. One patient had significant brachial artery thrombosis. Other complications included posterior interosseous nerve palsy, lateral antebrachial cutaneous nerve-related complication, and numbness about the radial nerve. sion e of a cortical suspensory fixation device in conjunction with an interference screw is an effective method of repairing a distal biceps rupture, with a low early rate of failure.
