Abstract：
Various surgical treatments are available for a symptomatic AN, including percutaneous drilling (PD). PD is reportedly effective for ANs in skeletally immature children. However, no reports have described the foot alignment after PD in skeletally immature children. This study was performed to compare the radiographic parameters between the preoperative period and the final follow-up after PD for symptomatic ANs in skeletally immature children. From October 2013 to December 2020, PD was performed on 13 feet in 10 skeletally immature children. The patients comprised 5 boys and 5 girls with a mean age at surgery of 11.9 years. The mean follow-up period was 14.8 months. We measured 5 radiographic findings preoperatively and at the final follow-up: calcaneal pitch angle (CPA), talocalcaneal angle (TCA), talonavicular coverage angle (TNCA), anteroposterior talo-first metatarsal angle (ATMA), and lateral talo-first metatarsal angle (LTMA). Ten feet were assessed as excellent, 1 as fair, and 2 as poor. Ten unions (76.9%) were achieved among the 13 feet. The mean CPA improved from 16.4 ± 4.1 degrees preoperatively to 18.2 ± 3.4 degrees at the final follow-up, the TCA improved from 43.0 ± 3.7 to 45.2 ± 4.4 degrees, and the TNCA improved from 19.9 ± 4.4 to 15.4 ± 5.0 degrees (P < .05). The ATMA and LTMA were not significantly different between the preoperative period and final follow-up. We found that PD for symptomatic ANs in skeletally immature children was effective treatment, and some radiographic parameters showed significant differences between the preoperative period and final follow-up.
摘要：
各种手术治疗可用于有症状的AN，包括经皮钻孔（PD）。据报道，PD对骨骼未成熟儿童的AN有效。然而,没有报告描述骨骼未成熟儿童PD后的足部对齐情况.进行这项研究是为了比较骨骼未成熟儿童有症状的ANs的术前期间和PD后最终随访之间的影像学参数。从2013年10月到2020年12月，在10名骨骼未成熟儿童的13英尺上进行了PD。患者包括5名男孩和5名女孩，手术时平均年龄为11.9岁。平均随访时间为14.8个月。我们在术前和最终随访时测量了5个影像学发现：跟骨俯仰角（CPA），距骨角度(TCA),距骨覆盖角(TNCA),前后距骨-第一跖骨角(ATMA),和外侧距骨第一跖骨角（LTMA）。十英尺被评估为优秀，1公平，2、穷。在13英尺中实现了10个工会（76.9％）。平均CPA从术前的16.4±4.1度提高到最终随访的18.2±3.4度，TCA从43.0±3.7提高到45.2±4.4度，TNCA从19.9±4.4提高到15.4±5.0（P<0.05）。ATMA和LTMA在术前和最终随访之间没有显着差异。我们发现，对于骨骼不成熟儿童的症状性ANs，PD是有效的治疗方法，一些影像学参数显示术前和最终随访之间存在显着差异。
