RESUMEN
As the field of vascularized composite allotransplantation continues to expand, new upper extremity transplant candidates are being considered. We recently evaluated a bilateral amputee who had a mid-forearm amputation and a contralateral metacarpal hand amputation. In the latter limb, a "partial" hand transplant that preserved the majority of the patient's existing hand, including a partially severed thumb with intact thenar muscle function, was proposed. The feasibility of this partial hand transplant was studied in fresh-frozen cadaver limbs. This report details the proposed approach, the cadaveric dissections, and the lessons learned from these dissections. Issues of osteosynthesis, microvascular planning, and intrinsic muscle recovery are discussed, all of which are critical considerations for partial hand transplant candidates. Ultimately, the partial hand approach was felt to be inferior to a more conventional distal forearm transplant in this particular candidate. Practical, functional, and ethical implications of such decision are presented.
