Trans-digit Salvage Replantation Using Part of an Amputated Digit for Reconstruction of Thumb Pulp

Abstract

Hand trauma is a common problem in daily practice. Restoration of hand function is important, especially for the pulp defect. Pulp defect can be reconstructed by many methods. However, every method has some limitations and drawbacks, like donor site deformity and morbidity. It is common for hand trauma to have multiple fingers involvement. The option of the treatments depends on the extent of tissue damage. For the non-replantable amputated finger, the residual viable tissue of the amputated part can be used for other finger defect reconstruction. We reported a patient having left hand crush injury with small finger avulsion amputation at the level of metacarpophalangeal joint and thumb pulp defect. A fillet flap was harvested from the non-replantable small finger to reconstruct the pulp defect of thumb. At one-year of follow-up, good functional result and aesthetic appearance were archived.
