Background: Distal biceps ruptures can result in ongoing pain and weakness when treated nonoperatively. If retraction of the tendon renders primary repair impossible, reconstruction using a graft is recommended. The current literature includes a variety of techniques with studies reporting small patient numbers. The aim of this study was to report the results of a larger cohort of patients using a technique modified from those previously described in the literature.
Methods: Twenty-one consecutive male patients underwent distal biceps reconstruction through 2 small anterior incisions using an Achilles tendon allograft that was fixed distally using a transosseous EndoButton and secured proximally using a Pulvertaft weave and tendon wrap. The mean age was 44 years, and the mean time to surgery was 25 months (range, 2-96 months). Functional outcomes were collected prospectively.
Results: The mean preoperative Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score (11 patients) was 1.9 (range, 0-4.5). The mean postoperative Oxford Elbow Score, QuickDASH score, and Mayo Elbow Performance Score were 44.7 (range, 35-48), 4 (range, 0-20.5), and 92.9 (range, 70-100), respectively, at a mean follow up of 15 months (range, 6-35 months). The mean postoperative QuickDASH score was significantly improved compared with preoperatively (P < .001). All patients were satisfied and all returned to their previous level of activity. There were 2 transient lateral antebrachial cutaneous nerve paresthesias, and 2 patients had a 5° extension lag. There were no other complications.
Conclusion: Achilles allograft reconstruction of retracted irreparable distal biceps ruptures provides consistently good results with few complications using this technique.
