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.
