Records of 220 thoroughbred horses presented to the Randwick Equine Centre or the University of Queensland Veterinary Teaching Hospital for surgical management of carpal injury were reviewed. Details of racing performance were obtained, enabling evaluation of racing success following surgery. Age and sex matched control horses not known to have suffered carpal injury were selected from the Australian Stud Book and the Australian Racehorse Register. Control and treated populations were compared in terms of overall career racing success. Radiographs or xeroradiographs from 198 horses were available for evaluation. The dorsomedial aspects of the distal articular surface of the radial carpal bone and the proximal articular surface of the third carpal bone were the most commonly observed locations of osteochondral fracture. Bilateral carpal injury was found to be sufficiently common to warrant routine radiographic examination of both limbs. The dorsolareral-palmaromedial oblique, flexed lateral and dorsoproximal-dorsodistal oblique (skyline) projections were the most useful views for evaluation of carpal degenerative joint disease. Surgical removal of osteochondral fractures by arthrotomy or arthroscopy was found to be a suitable method of treatment. Arthroscopy was associated with a significantly shorter convalescent period than arthrotomy. Seventy-six percent of the treated population returned to racing following surgery. Average earnings following surgery were $20,000. However, the median value was only $1400 and 48% of the treated population failed to earn more than $1000. Male horses in both the treated and control groups performed significantly better than females. Treated horses performed significantly better than the randomly selected control population.
回顾了220匹因腕关节损伤而被送到兰德威克马科动物中心或昆士兰大学兽医教学医院进行手术治疗的纯种马记录。获取了赛马成绩的详细信息，以便评估手术后的赛马成功率。从澳大利亚种马登记簿和澳大利亚赛马登记册中挑选出年龄和性别匹配且无腕关节损伤记录的对照马。比较了对照组和治疗组在整个职业生涯中的赛马成功率。有198匹马的X光片或干板X光片可供评估。桡腕骨远端关节面的背内侧和第三腕骨近端关节面是最常观察到骨软骨骨折的部位。发现双侧腕关节损伤很常见，因此有必要对双肢进行常规X光检查。背外侧-掌内侧斜位、屈曲侧位和背近端-背远端斜位（轮廓）投照是评估腕关节退行性关节病最有用的视图。通过关节切开术或关节镜手术切除骨软骨骨折被认为是一种合适的治疗方法。与关节切开术相比，关节镜手术的恢复期明显更短。76%的治疗马匹术后恢复参赛。术后平均收入为20,000美元。然而，中位数仅为1400美元，48%的治疗马匹收入未超过1000美元。治疗组和对照组中的雄性马匹表现均明显优于雌性马匹。治疗后的马匹表现明显优于随机选择的对照组。
