Hallux valgus (HV) is one of the most common forefoot deformities among females, and its prevalence increases with age. This study aims to evaluate the effectiveness of three different types of orthotics on the reduction in hallux valgus angle (HVA) for patients with mild and moderate hallux valgus deformities.
Twenty-six patients (42 feet) with mild or moderate HV participated in the treatment with three types of orthotics in the current study. Patients were divided into three groups depending on their HV severities and the consideration of different function of the orthotics. Orthotic Type 1 is a biomechanical style orthotic applied to moderated HV in Group 1. Orthotic Type 2 is a wrap style orthotic used on mild and moderate HV with two sub-groups: mild HV in Group 2A and moderate HV in Group 2B. Orthotic Type 3 is a gel style orthotic for mild HV. Patients were required to wear the orthotics for between 6 and 8 h per night over a period of 12 months. The HVA was measured every 3 weeks using a newly designed Measuring Block. A paired t-test was used to compare the differences between initial and final HVA at different stages of HVA treatment with orthotics.
After the 12-month treatment, for moderate HV patients treated with the Orthotic Type 1, their HVA reduced by 5.05° (95% CI 1.37, 8.73), ( < 0.05). For moderate HV patients treated with the Orthotic Type 2, their HVA reduced by 1.2° (95% CI -0.71, 3.11) ( > 0.05). For mild HV patients treated with the Orthotic Type 2, their HVA reduced by 2.44° (95% CI 1.39, 3.49) ( < 0.05). For mild HV patients treated with the Orthotic Type 3, their HVA reduced by 3.08° (95% CI -0.68, 6.83) ( > 0.05).
Orthotic Type 1 showed a consistent significance in reduction in the HVA during the 12-month treatment, so it could be recommended for treating moderate HV. Orthotic Type 2 reduced the HVA, but it did not show a consistent significance in reduction in the HVA for mild and moderate HV. Orthotic Type 3 reduced the HVA, but it showed a volatile trend during 12 months without significant differences.
拇外翻（HV）是女性最常见的前足畸形之一，其患病率随着年龄的增长而增加。本研究旨在评估三种不同类型矫形器在轻度和中度拇外翻畸形患者中降低拇外翻角（HVA）的效果。
26 名（42 只脚）患有轻度或中度 HV 的患者参与了本研究中三种矫形器的治疗。根据 HV 严重程度和矫形器不同功能的考虑，患者分为三组。矫形器 1 型是一种应用于组 1中中度 HV 的生物力学风格矫形器。矫形器 2 型是一种包裹式矫形器，用于轻度和中度 HV，分为两个亚组：组 2A 为轻度 HV，组 2B 为中度 HV。矫形器 3 型是一种用于轻度 HV 的凝胶式矫形器。患者需要在 12 个月内每晚佩戴矫形器 6-8 小时。使用新设计的测量块每 3 周测量一次 HVA。使用配对 t 检验比较不同阶段使用矫形器治疗 HVA 时初始 HVA 和最终 HVA 之间的差异。
12 个月治疗后，1 型矫形器治疗的中度 HV 患者的 HVA 降低了 5.05°（95%CI 1.37，8.73），（<0.05）。2 型矫形器治疗的中度 HV 患者的 HVA 降低了 1.2°（95%CI-0.71，3.11）（>0.05）。2 型矫形器治疗的轻度 HV 患者的 HVA 降低了 2.44°（95%CI 1.39，3.49），（<0.05）。3 型矫形器治疗的轻度 HV 患者的 HVA 降低了 3.08°（95%CI-0.68，6.83），（>0.05）。
1 型矫形器在 12 个月的治疗过程中对 HVA 的降低一直有显著意义，因此可推荐用于治疗中度 HV。2 型矫形器降低了 HVA，但对轻度和中度 HV 的 HVA 降低没有一致的显著意义。3 型矫形器降低了 HVA，但在 12 个月内呈波动趋势，无显著差异。
