犬跗关节是由胫跗关节、跗间关节和跗跖关节等三个关节合成的复关节,胫跗关节为行屈伸运动的关节,其他关节为滑动关节。由于韧带和关节面的构造限制,关节的滑动性很小,稳定性较高。小腿远端的骨折会导致跗关节稳定结构遭到破坏,进而引发关节的半脱位或脱位。使用外固定技术对其进行治疗往往会出现骨复位不确实,持续性的不稳定最终可导致退行性关节病[1]。小型犬和猫的腓骨远端为其外踝,在靠近其末端处易发生骨折。兽医临床上针对小
Dog 跗 joint is composed of tibiofibular joint, 跗 joint and tarsometatarsal joint synthesis of three joints, tibiofibular joint flexion and extension joints, the other joints for the sliding joint. Due to the structural limitations of the ligaments and articular surfaces, the joints are less slippery and more stable. Distal calf fractures can lead to the destruction of the stable structure of the 跗 joint, which in turn causes subluxation or dislocation of the joint. The use of external fixation for treatment of bone remodeling is often not accurate, and persistent instability can eventually lead to degenerative joint disease [1]. The distal end of the fibula of small dogs and cats is their lateral malleolus, and fractures tend to occur near their ends. Veterinary clinics for small
