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

• Conditions: Amputation, Traumatic; Pinprick Sensation Diminished; Pain

• Registration Number: NCT02419885
• Lead Sponsor: Kaohsiung Medical University Chung-Ho Memorial Hospital

Brief Summary

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.

Detailed Description

Fingertip amputations underwent

1. modified composite grafting with pulp Adipo-fascia advance flap

2. composite graft

3. revision amputation was collected in this study

Follow-up was arranged in out-patient department, including:

type of amputation ( Hirase classification, ) 2-point discrimination test, DASH(Disabilities of the Arm, Shoulder, and Hand) outcome measure, graft survival, pain evaluation with visual Analog scale other associated treatment such as hyperbaric oxygen therapy length of finger shortening at 6 month after operation
