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.

Patients and methods

Twenty-one consecutive patients underwent reconstruction by a single technique performed by or under the direct supervision of the senior author (A.C.W.). All patients were men, and the mean age was 44 years. The indication for reconstruction was a symptomatic, retracted distal biceps rupture that could not be fixed directly to the radial tuberosity using a transosseous EndoButton technique in up to 90° of elbow flexion.

Preoperative demographic data and postoperative outcome scores, range of

Results

Table I shows individual preoperative patient demographic data. The mean follow-up period for the 21 patients was 15 months (range, 6-35 months). The mean age was 44 years (range, 20-62 years). Seventeen patients were right handed, and 11 right arms were treated. Of the patients, 12 had a manual occupation, 8 had a sedentary occupation, and 1 was a rugby player. Seven of the 12 patients with manual jobs were heavy-goods vehicle drivers. In 12 patients, the initial biceps rupture occurred while

Discussion

In this series of 21 patients with retracted, irreparable distal biceps ruptures, we found consistently good functional outcomes, a high level of patient satisfaction, and few complications. The surgical technique described uses an Achilles tendon allograft, EndoButton fixation distally, and a Pulvertaft weave with tendon wrap to secure the graft proximally. The use of Achilles tendon allograft avoids additional graft-site morbidity and is known to have equivalent mechanical properties to

Conclusion

Patients treated with Achilles allograft reconstruction of the distal biceps using an EndoButton and Pulvertaft weave reconstruction with tendon wrap had good clinical results with an improvement in preoperative disability and few complications. This technique is recommended for patients who have a retracted, irreparable distal biceps rupture.

    The present study found functional elbow range of motion was reliably restored in patients undergoing allograft reconstruction or direct primary repair. This is consistent with previous reports on elbow range of motion after graft reconstruction.8,10,23,28 Although the present study did not evaluate postoperative elbow strength—previous studies have reported similar restoration of postoperative supination strength between graft reconstruction and direct primary repair.
