In-toeing of the foot was associated with high femoral version (FV), while Out-toeing was associated with femoral-retroversion. Therefore, we report on (i) foot-progression-angle (FPA), (ii) prevalence of In-toeing and Out-toeing, and (iii) clinical outcome of patients treated with femoral-derotation-osteotomy (FDO). We performed a retrospective analysis involving 20 patients (20 hips) treated with unilateral FDO (2017-18). Of them, 14 patients had increased FV, 6 patients had femoral-retroversion. Follow-up time was mean 1 ± 1 years. All patients had minimal 1-year follow-up and the mean age was 29 ± 8 years. Patients with increased FV (FV > 35°) presented with positive posterior-impingement-test and mean FV was 49 ± 11° (Murphy method). Six patients with femoral-retroversion (FV < 10°) had positive anterior impingement test and mean FV of 5 ± 4°. Instrumented gait analysis was performed preoperatively and at follow-up using the Gaitrite system to measure FPA and was compared to a control group of 18 healthy asymptomatic volunteers (36 feet, mean age 29 ± 6 years). (i) Mean FPA increased significantly ( = 0.006) from preoperative 1.3 ± 7° to 4.5 ± 6° at follow-up for patients with increased FV and was not significantly different compared to the control group (4.0 ± 4.5°). (ii) In-toeing decreased from preoperatively (five patients) to follow-up (two patients) for patients with increased FV. Out-toeing decreased from preoperatively (two patients) to follow-up (no patient) for patients with femoral-retroversion. (iii) Subjective-hip-value of all patients increased significantly ( < 0.001) from preoperative 21 to 78 points at follow-up. WOMAC was 12 ± 8 points at follow-up. Patients with increased FV that underwent FDO walked with less In-toeing. FDO has the potential to reduce In-toeing and Out-toeing and to improve subjective satisfaction at follow-up.
足部内旋与股骨前倾角增大（FV）相关，而足部外旋与股骨后倾相关。因此，我们报告了（i）足进角（FPA）、（ii）内旋和外旋的患病率以及（iii）接受股骨旋转截骨术（FDO）治疗患者的临床结果。我们对20例（20髋）接受单侧FDO治疗的患者（2017 - 2018年）进行了回顾性分析。其中，14例患者FV增大，6例患者存在股骨后倾。随访时间平均为1±1年。所有患者至少随访1年，平均年龄为29±8岁。FV增大（FV>35°）的患者后撞击试验呈阳性，平均FV为49±11°（墨菲法）。6例股骨后倾（FV<10°）的患者前撞击试验呈阳性，平均FV为5±4°。术前和随访时使用步态分析系统进行仪器化步态分析以测量FPA，并与18名健康无症状志愿者组成的对照组（36足，平均年龄29±6岁）进行比较。（i）FV增大的患者，平均FPA从术前的1.3±7°显著增加（P = 0.006）至随访时的4.5±6°，与对照组（4.0±4.5°）相比无显著差异。（ii）FV增大的患者，内旋从术前的5例减少至随访时的2例。股骨后倾的患者，外旋从术前的2例减少至随访时的0例。（iii）所有患者的主观髋关节评分从术前的21分显著增加（P<0.001）至随访时的78分。随访时WOMAC评分为12±8分。接受FDO治疗的FV增大患者行走时内旋减少。FDO有可能减少内旋和外旋，并提高随访时的主观满意度。
