Abstract：Objective To investigate the clinical effects of epithelialization with artificial dermis versus digital ar-tery flap repair for small finger wounds.Methods A retrospective analysis was conducted on 43 cases(47 fingers)trea-ted with artificial dermis and 45 cases(48 fingers)treated with digital artery flap repair from January 2021 to June 2023.The two groups were compared based on hospital stay duration,wound healing time,two-point discrimination,scar qual-ity(VSS),and hand function scores(MHQ).Results Baseline characteristics,including sex,age,cause of injury,affected fingers,defect area,and follow-up duration,showed no significant differences between the groups(P＞0.05),indicating comparability.The hospital stay was shorter in the artificial dermis group[(5.64±3.17)days]compared to the flap group[(10.88±4.98)days].The wound healing time was significantly shorter in the artificial dermis group[(28.62±5.34)days]than in the flap group[(17.81±2.70)days](P＜0.05).Two-point discrimination was sim-ilar between groups[(4.70±0.73)mm vs.(4.74±0.71)mm,P＞0.05).The MHQ score was higher in the artificial dermis group(87.18±3.73)compared to the flap group(80.81±4.85)(P＜0.05).VSS scores showed no significant difference(4.23±1.07 vs.4.29±1.15,P＞0.05).Conclusion Both artificial dermis epithelialization and digital ar-tery flap repair are effective for small tendon or bone-exposed finger wounds.However,the use of artificial dermis is sim-pler and results in better functional recovery,making it a viable option in clinical practice.
