This study aimed to analyze the reliability and validity of the Vancouver Scar Scale (VSS) and the Withey score after syndactyly release. Over a 3-year period, 13 patients who underwent syndactyly release were evaluated. The mean age at the time of syndactyly release was 12 months (range, 8–18 months), and the mean follow-up period was 29 months (range, 17–52 months). We obtained hand photographs and finger motion videos and collected the satisfaction scores for hand function and cosmesis. Three clinicians evaluated the hand photographs and finger motion video of each patient twice using the VSS and the Withey score. The interobserver and intraobserver reliabilities of the VSS and Withey score were determined using intraclass correlation coefficients (ICCs). The validity of the VSS and Withey score was determined using Spearman’s correlation test with the functional and cosmetic satisfaction score. The ICCs for the interobserver reliability of VSS were 0.31 and 0.39 for each measurement, and ICCs for the intraobserver reliability of VSS were 0.46, 0.51, and 0.54 for each observer. The ICCs for the interobserver reliability of the Withey score were 0.74 and 0.70, and the ICCs for the intraobserver reliability of the Withey score were 0.91, 0.74, and 0.96. The Withey score was significantly correlated with the satisfaction score for hand function and hand cosmesis, but the VSS was not. The VSS had poor interobserver reliability and fair intraobserver reliability, whereas the Withey score had good interobserver reliability and excellent intraobserver reliability based on photographic evaluation after syndactyly release.

本研究旨在分析并指释放后温哥华疤痕量表（VSS）和Withey评分的信度和效度。在 3 年期间，对 13 名接受并指松解术的患者进行了评估。并指释放时的平均年龄为 12 个月（范围，8-18 个月），平均随访期为 29 个月（范围，17-52 个月）。我们获得了手部照片和手指运动视频，并收集了手部功能和美容的满意度分数。三名临床医生使用 VSS 和Withey 评分对每位患者的手部照片和手指运动视频进行了两次评估。VSS 和Withey 评分的观察者间和观察者内信度使用组内相关系数（ICC）确定。VSS 和Withey 评分的有效性是使用 Spearman 的相关性检验与功能和美容满意度评分来确定的。每次测量的 VSS 观察者间可靠性的 ICC 分别为 0.31 和 0.39，每个观察者的 VSS 观察者内可靠性的 ICC 分别为 0.46、0.51 和 0.54。Withey 评分的观察者间信度的 ICC分别为 0.74 和 0.70，Withey 评分的观察者间信度的 ICC 分别为0.91、0.74和 0.96。威西得分与手部功能和手部美容满意度得分显着相关，但VSS则不然。VSS 的观察者间信度差，观察者内信度一般，而Withey 评分有良好的观察者间信度和良好的观察者内信度，基于并指释放后的照片评价。
