About

Microvascular partial toe transfer for reconstruction of traumatic amputation of the digits

Full description

Microsurgical toe transfer has become a gold standard option for amputated digit reconstruction. It can be used to correct almost any thumb defect. However, for optimal functional and esthetic results, proper initial care, preoperative planning, proper selection of suitable techniques, adjunct or secondary procedures and proper, postoperative rehabilitation are important.

The transfer of a toe to replace an amputated thumb represents one of the first applications of microsurgical techniques, yet to this day remains an epitome of reconstructive surgery, restoring critical function and form to the hand-injured patient. While techniques have greatly evolved to permit the treatment of multiple finger amputations, dystrophic nails and pulps, and traumatized or arthritic joint, the amputated thumb retains its status among the most indubitable indications for toe transfer. Microsurgical techniques have been refined to such a degree that almost any ablative deformity of the thumb could be corrected with some form of toe transfer. The question, therefore, is not if a defect could be reconstructed, but whether the patient is willing to undergo reconstruction. The concepts of "adequate function" and "optimal function" are therefore of central importance when discussing treatment options with a patient. Obviously, these parameters will be different for each patient depending upon his/her vocation, avocations, and desires. For many people, adequate function might be expected with an amputation that retains some length of the proximal phalanx (assuming sufficient soft tissue coverage is present or can be provided). However, for patients who require full length of their thumb, or who desire optimal rather than adequate function, toe transfer should be considered.

At present, the decision to use a particular toe transfer technique is mostly based on the surgeon's preference and training. The current data are inadequate to make any comments with regards to donor site morbidity. Till such data are available, an evidence-based recommendation for the superiority of a specific type of toe-to-thumb transfer cannot be made. We hypothesis that partial toe transfer provides the best aesthetic and functional reconstruction and the least donor site morbidity amongst all other types of transfers.
