Minimally Invasive Distal Biceps Tendon Reconstruction With Semitendinosus Allograft and Dual Unicortical Button Fixation

Abstract

Complete rupture of the distal biceps tendon is routinely treated with direct repair; however, chronic, mid-substance, or musculotendinous tears are challenging clinical scenarios for surgeons. Although attempts at direct repair should be considered, in cases of severe retraction or tendon deficiency, a reconstruction may be warranted. Herein the authors describe a technique for distal biceps reconstruction using allograft with a Pulvertaft weave via a standard anterior incision, similar to primary repair, with a small catchment incision more proximally for tendon retrieval. Use of this technique with dual unicortical buttons allows for early range of motion, restoration of the distal footprint, and improved biomechanical construct strength, which has proven invaluable in a population of elite and highly active military servicemembers.
