■脚畸形可导致踝关节的生物力学异常和骨关节炎的发展。据推测,足部畸形与内侧踝关节骨关节炎有关,这项研究使用射线照相测量调查了这种关系。
■76名患者的76个脚踝(32名男性和44名女性;平均年龄,包括69.0年)的内侧踝关节骨关节炎。11次影像学测量评估了踝关节方向(胫骨平台倾斜度[TPI],胫骨远端内侧角[MDTA],和胫骨远端前角[ADTA]),踝关节不一致(胫骨倾斜[TT]),足部畸形(外侧距骨第一跖骨角[Lattalo-1MT],前后距骨-第一跖骨角[APtalo-1MT],和距骨覆盖),距体迁移(距骨中央内侧迁移[MTCM]和距骨中央前移[ATCM]),距骨的内部旋转(IR),和机械胫骨股角度。采用Pearson相关系数和回归分析进行统计学分析。
■踝关节朝向地面(TPI,p=0.002),增加足弓(Lattalo-1MT,p<0.001),在线性回归分析中,距骨的IR(p=0.001)与踝关节不一致(TT)显着相关。踝关节不一致(TT,p=0.003),距骨内侧体迁移(MTCM,p=0.042),和增加的足弓(Lattalo-1MT,p=0.022)在二元逻辑回归分析中与距骨的IR显着相关。MTCM与TPI显著相关(r=0.251,p=0.029),TT(r=0.269,p=0.019),MDTA(r=0.359,p=0.001),ATCM(r=-0.522,p<0.001),和APtalo-1MT(r=0.296,p=0.015)。ATCM与TPI显著相关(r=-0.253,p=0.027),ADTA(r=0.349,p=0.002),和Lattalo-1MT(r=-0.344,p=0.002)。
■踝关节方向,足部畸形,影像学评估时,踝关节旋转与内侧踝关节骨关节炎的踝关节不一致有关。在内侧踝关节骨关节炎的手术治疗过程中需要考虑这些发现。然而,这些射线照相测量的生物力学意义需要进一步研究。
UNASSIGNED: Foot deformities can cause abnormal biomechanics of the ankle joint and the development of osteoarthritis. It was hypothesized that foot deformities would be related to medial ankle osteoarthritis, and this study investigated this relationship using radiographic measurements.
UNASSIGNED: Seventy-six ankles of 76 patients (32 men and 44 women; mean age, 69.0 years) with medial ankle osteoarthritis were included. Eleven radiographic measurements evaluated ankle joint orientation (tibial plafond inclination [TPI], medial distal tibial angle [MDTA], and anterior distal tibial angle [ADTA]), ankle joint incongruency (tibiotalar tilt [TT]), foot deformities (lateral talo-first metatarsal angle [Lat talo-1MT], anteroposterior talo-first metatarsal angle [AP talo-1MT], and talonavicular coverage), talar body migration (medial talar center migration [MTCM] and anterior talar center migration [ATCM]), internal rotation (IR) of the talus, and mechanical tibiofemoral angle. All were statistically analyzed using Pearson\'s correlation coefficients and regression analyses.
UNASSIGNED: Ankle joint orientation to the ground (TPI, p = 0.002), increased foot arch (Lat talo-1MT, p < 0.001), and IR of the talus (p = 0.001) were significantly associated with ankle joint incongruency (TT) in linear regression analysis. Ankle joint incongruency (TT, p = 0.003), medial talar body migration (MTCM, p = 0.042), and increased foot arch (Lat talo-1MT, p = 0.022) were significantly associated with IR of the talus in the binary logistic regression analysis. MTCM was significantly correlated with TPI (r = 0.251, p = 0.029), TT (r = 0.269, p = 0.019), MDTA (r = 0.359, p = 0.001), ATCM (r = -0.522, p < 0.001), and AP talo-1MT (r = 0.296, p = 0.015). ATCM was significantly correlated with TPI (r = -0.253, p = 0.027), ADTA (r = 0.349, p = 0.002), and Lat talo-1MT (r = -0.344, p = 0.002).
UNASSIGNED: Ankle joint orientation, foot deformities, and talar rotation were associated with ankle joint incongruency in medial ankle osteoarthritis when evaluated radiographically. These findings need to be considered during surgical treatment for medial ankle osteoarthritis. However, the biomechanical significance of these radiographic measurements requires further investigation.
