Endoscopic single-incision extensor indicis transposition for extensor pollicis longus reconstruction

Traditional methods for harvesting the extensor indicis (EI) tendon for transposition to the extensor pollicis longus (EPL) tendon using direct visualization commonly require 3 incisions. The authors describe an endoscopic EI tendon transposition for EPL tendon reconstruction as an alternative technique for the traditional open technique. This new modification of endoscopic EI transposition to EPL has the benefit over the standard harvesting technique of only 1 incision to accomplish the complete procedure and results in less scarring. To date, the authors have only operated on ruptures after radius fractures without significant synovitis in the area of the extensor compartment.
