Distal biceps section and reinsertion for chronic distal biceps tendinopathy

BACKGROUND: Surgical reinsertion of the distal biceps tendon for acute and chronic tears is a widely accepted procedure, but little is known about surgical treatment of distal biceps tendinopathy. METHODS: Twenty patients underwent a surgical procedure for distal biceps tendinopathy after failure of conservative treatment. The surgery was performed through a single incision. The biceps tendon was detached, debrided and reinserted using a ToggleLoc (Zimmer Biomet) device. Clinical and radiologic evaluation was performed after a minimum follow-up of 1 year. Quick-Dash score, Liverpool Elbow Score, Mayo Elbow Performance Index, Broberg and Morrey Score and Short HSS Scoring System were used, and isokinetic testing was performed. RESULTS: The outcome of these five clinical elbow scores showed no clinically relevant differences between the affected and non-affected side. Isokinetic testing of peak torque in flexion and supination showed equal strength between both sides. These results indicate good functional outcome and recovery of flexion and supination, compared to the non-operated side and the normal population. CONCLUSION: This study demonstrates that distal biceps tendon debridement and reinsertion is a safe and valid option for patients with distal biceps tendinopathy after failure of conservative treatment. LEVEL OF EVIDENCE: Level 3 retrospective cohort study.
