Abstract:
In this study, we compared outcomes in patients with acute hand injury, who were managed with or without negative pressure wound therapy (NPWT) after reconstructive surgery. All of the patients who sustained acute and multitissue injuries of the hand were identified. After reconstructive surgery, a conventional dressing was applied in Group 1 and NPWT was applied in Group 2. The dressing and NPWT were changed every 3 days. The mean age and Hand Injury Severity Scoring System score of both groups were not significantly different. Disabilities of the Arm, Shoulder, and Hand (DASH) scores were evaluated 1 month after all the sutures were removed and 1 year postoperatively, which were both significantly lower in Group 2. Applying NPWT to the hand promoted wound healing by reducing edema, stabilizing the wound, and providing immobilization in a functional position. Early wound healing and decreased complications enabled early rehabilitation, which led to successful functional recovery, both objectively and subjectively.
