Cortical suspensory fixation with interface screw showed low early rate of failure
When repairing a distal biceps rupture, the use of a cortical suspensory fixation device in conjunction with an interference screw was an effective method with a low early rate of failure, according to study results.
Researchers retrospectively identified 170 distal biceps ruptures in 168 consecutive patients treated using a cortical button in conjunction with an interference screw. The researchers reviewed patient records from the time of the initial clinical visit to the most recent follow-up, defining failures as those that occurred within 12 weeks of the index procedure, and failed repair as tendon defect, deformity or significant weakness in supination.
Results showed an early incidence failure of 1.2%, with two of the fixations meeting the criteria for failure. The researchers found only one patient had significant brachial artery thrombosis, whereas other complications included posterior interosseous nerve palsy, lateral antebrachial cutaneous nerve-related complication and numbness about the radial nerve.
