Ideally, reconstruction should restore thumb length and position and retain thumb stability, mobility, and strength, while preserving sensation and aesthetics. Achieving these outcomes can be especially challenging in severe cases of soft tissue and bony loss. The authors present a case of a 20-year-old right-hand dominant female involved in a motor vehicle accident who sustained severe crush injuries and burns to her right hand. Her injuries included soft tissue and bony defects extending from the thumb to the distal radius, namely avulsion of the thumb and significant loss of the distal radial and carpal column, resulting in severe wrist instability. We employed a three-segment vascularized osteocutaneous fibula flap to reconstruct the thumb and wrist to restore bony construct, carpal support, and soft tissue coverage. Thumb motion could not be achieved, but this technique offered a sensate, functional post for opposition and the appearance of an anatomic hand. Because of this surgery, the patient was enabled to graduate from college and pursue full-time employment. The authors hope that this report will add to the fund of knowledge and surgeon armamentarium for similar devastating injuries demanding thumb and wrist reconstruction.展开更多

Optimal management of thumb loss necessitates individual consideration of surgical versus prosthetic options, in relation to the needs and circumstances of each patient. This paper presents a case of prosthetic pollicization of an amputated thumb and emphasizes on the fact that the prosthetic replacement has a definite edge over surgical procedures, where amputees refuse to undergo more complicated surgical procedures. The patient was rehabilitated successfully by a noninvasive and cost-effective approach by using high temperature-vulcanized (HTV) silicone material and retaining the prosthesis with medical adhesives. On 3 months recall ap-pointment, no complications were found. The prosthesis was in good shape, without need for any repairs.展开更多
