Congenital Hypoplasia of the Extensor Tendons of the Fingers: A Case Report and Review of the Literature

摘要

We present a rare case and unusual presentation of digital extensor tendon congenital hypoplasia. A 34-year-old woman presented to our clinic with the inability to extend her index, middle, and ring fingers since birth. Her tendons were reconstructed using transfer of flexor digitorum superficialis tendons from the middle and ring fingers to the extensor aponeurosis of the index, middle, and ring fingers. An acellular dermal substitute was applied in a novel way to reconstruct the extensor retinaculum and promote a successful functional outcome.
