This is a retrospective review of 9 patients who underwent repair of a chronic distal biceps tendon rupture using an autograft repair. The mean age of the patients was 47 years and the mean delay from injury to surgery was 4.1 months (range 2.5-6.5 months).
All patients had an autogenous semitendinous graft harvested from the medial aspect of the knee with tendon stripper. The tendon was first fixed to the radius. Then the hamstring was woven through the retracted native tendon in a criss-cross fashion. The tension applied was the length needed to reach the tuberosity arm at 90° of flexion at full supination. The graft was then repaired.
The results indicate that the procedure could be performed with a mean flexion contracture of only 3°. Isometric strength deficit substantially improved compared to pre-operative findings. Although rarely needed from a functional standpoint, biceps reconstruction can restore muscle function following chronic rupture. Allograft remains an alternative to harvest of the patients hamstring.
