METHODS: Pirani scores were retrospectively collected from 17 AMC patients with a total of 30 clubfeet and two years follow-up from initiation of treatment. Patients with a minimum of three casting series were included. Pre-treatment and post-treatment deformity scores were examined across casting series using analysis of variance (ANOVA) statistical analysis.
RESULTS: The first series pre-treatment Pirani score improved from 4.80±1.54 to 1.68±1.48 (p<0.001). The second series improved from 4.23±1.03 to 2.72±0.916 (p<0.001). The third series had the smallest improvement from 3.87±1.07 to 2.82±1.02 (p<0.001). Change in Pirani scores showed a significant decrease from the first series to the second (p=0.001) and third (p<0.001). In addition, the number of casting days was found to significantly affect the change in scores during the third series (p=0.038).
CONCLUSIONS: The Ponseti technique can improve clubfoot in AMC as measured by the Pirani score. Data shows that early intervention yields better results, with a diminished yet effective ability to elicit change over time.
方法:回顾性收集了17例AMC患者的皮拉尼评分,这些患者共30只马蹄,并在治疗开始后进行了两年的随访。包括至少三个铸造系列的患者。使用方差分析(ANOVA)统计分析检查整个铸件系列的治疗前和治疗后畸形评分。
结果:第一系列治疗前的皮拉尼评分从4.80±1.54提高到1.68±1.48(p<0.001)。第二个系列从4.23±1.03提高到2.72±0.916(p<0.001)。第三个系列的改善最小,从3.87±1.07降至2.82±1.02(p<0.001)。皮拉尼评分的变化显示,从第一个系列到第二个系列(p=0.001)和第三个系列(p<0.001)显着降低。此外,在第三系列中,铸造天数显着影响分数的变化(p=0.038)。
结论:通过Pirani评分测量,Ponseti技术可以改善AMC中的马蹄内翻足。数据显示,早期干预效果更好,随着时间的推移,引起变化的能力减弱但有效。
