This report describes the use of a minimally invasive standing pastern arthrodesis technique for the treatment of osteoarthritis in horses and documents its clinical outcome in 12 horses.
Medical records and radiographs of horses diagnosed with proximal interphalangeal joint osteoarthritis that underwent standing pastern arthrodesis using transarticular screws were reviewed. Follow-up information for determination of outcome was obtained via phone interview with the owners.
Twelve horses (15 limbs) were included in the study. Radiographical findings revealed severe osteoarthritis in 12/15 limbs and moderate osteoarthritis in 3/15 limbs. Follow-up information was available for 11/12 cases (13/15 limbs). Phone surveys with the owners revealed that 8/11 horses were performing at their previous activity level or higher. Two horses remained lame. One horse developed a surgical site infection and was euthanatized. The average time for horses to return to their previous level of activity was 6.5 months (range: 1-18 months).
Stabilization of the proximal interphalangeal joint in horses with moderate-to-severe osteoarthritis can be performed using this minimally invasive standing technique. This procedure can be performed safely and provides a similar outcome when compared with other described techniques.
本报告描述了一种微创站立式系关节融合术治疗马骨关节炎的方法，并记录了12匹马的临床结果。
回顾了经关节螺钉进行站立式系关节融合术治疗近端指间关节骨关节炎的马的病历和X光片。通过与马主电话访谈获取用于确定结果的随访信息。
12匹马（15个肢体）纳入研究。影像学检查发现15个肢体中有12个存在严重骨关节炎，3个存在中度骨关节炎。12例中的11例（15个肢体中的13个）有随访信息。对马主的电话调查显示，11匹马中有8匹恢复到了之前或更高的活动水平。2匹马仍跛行。1匹马发生手术部位感染后实施了安乐死。马恢复到之前活动水平的平均时间为6.5个月（范围：1 - 18个月）。
对于中重度骨关节炎的马，可采用这种微创站立技术稳定近端指间关节。该手术可安全实施，与其他已描述的技术相比，效果相似。
