踝关节骨性关节炎是中老年人踝部疼痛的主要原因之一,以内踝骨性关节炎最为常见,其病因尚不清楚,主要临床表现为踝关节疼痛。病变早期踝关节活动不便,以后活动度逐渐减少。这种疾病保守治疗效果欠佳,目前公认有效的治疗手段为踝关节内侧胫骨低位截骨矫形术和全踝关节置换术[1-3],但以上2种方法均存在创伤大、费用高、技术水平要求高的缺点,其手术并发症也相对较多。
张英泽教授等[4]提出不均匀沉降理论,该理论认为踝关节骨性关节炎和膝关节骨性关节炎一样,是由于腓骨支撑导致的胫腓骨在人体衰老过程中的不均匀沉降引起。经过初步生物力学实验证实,对于内踝骨性关节炎,在外踝上方6 cm处将腓骨截除1~2 cm,有利于踝关节所承受应力的重新分配,从而有效地缓解由内踝间隙变窄造成的疼痛(图1,2)。拟在下一步开展临床研究,其纳入标准为非手术治疗无效的内踝骨关节炎,排除标准为由于骨关节创伤、畸形和踝关节不稳定引起的终末期踝关节炎。

The non-uniform settlement theory for ankle osteoarthritis
[Abstract]Based on the non-uniform settlement theory of professor Yingze Zhang,the tibia,as a load-bearing bone,takes place apparent settlement due to osteoporosis in the human aging process,which does not occur in the fibula.Therefore,it leads to medial compartment of knee and ankle arthritis simultaneously.For the medial compartment of ankle arthritis,the fibula can be cut 1-2 cm at 6 cm above the lateral malleolus.And it will restore ankle joint space,effectively relieve pain.
