Evaluation of Result and Influence Factors on Composite Graft in Fingertip Amputation

Fingertips facilitate smooth motor activity, precise sensation, and the delicate movement of the hands and have an aesthetic function. Fingertip injuries are defined as injuries occurring distal to the insertion of the flexor and extensor tendons. These injuries are one of the most common trauma injuries presented in acute care settings, accounting for approximately 4.8 million emergency department visits per year in the United States.(1) Fingertip amputations may not constitute the majority among these fingertip injuries but can have a complex spectrum of injury. In these cases, the reconstruction methodologies focus on preserving the digital length, ensuring adequate soft tissue coverage, preserving the nail structure, achieving a well-contoured and painless fingertip, and restoring durable and sensate skin. There are so many factor that influence the result of composite graft in distal finger tip amputation. Investigators will collected the data including the size of amputee , shape, level of amputation, mechanism of amputation, if hyperbaric oxygen therapy, operation procedures.
