To compare outcomes after semitendinosus tenotomy performed under standing sedation versus general anesthesia.
Retrospective case series.
20 horses with fibrotic myopathy of the semitendinosus muscle.
Medical records (2002-2015) of horses undergoing tenotomy of the semitendinosus muscle for the treatment of fibrotic myopathy were reviewed. Signalment, history, affected muscles, restrain method, surgical procedures, and short-term outcome as well as complications were retrieved from records. Long-term outcome (gait and athletic function) was assessed at least 6 months postoperatively by conversation with the owners. Pearson's χ statistical analysis was used to compare restrain method and affected muscles with overall outcome. Significance was set at P < .05.
Tenotomy of the semitendinosus muscle was performed under standing sedation in 8 horses and under general anesthesia in 12 horses. Follow-up period ranged from 9 months to 10 years. Gait was improved to variable degrees in 8 of 14 horses when the semitendinosus muscle alone was affected and in 4 of 6 horses when both the semitendinosus and semimembranosus muscles were involved (P = .11). Six of 8 horses treated under standing sedation and 6 of 12 horses treated under general anesthesia exhibited some improvement in the characteristic fibrotic gait (P = .4473). Five of 6 athletic horses treated under standing sedation and 6 of 9 athletic horses treated under general anesthesia returned to their preinjury level of athleticism. Horses treated under standing sedation had no incisional complications; 2 of 12 horses treated under general anesthesia exhibited incisional drainage.
Tenotomy of the semitendinosus muscle in horses with fibrotic myopathy leads to similar improvement in gait, whether performed under standing sedation or general anesthesia.
比较在站立镇静和全身麻醉下进行半腱肌切断术后的结果。
回顾性病例系列。
20匹患有半腱肌纤维化肌病的马。
回顾了2002年至2015年因治疗纤维化肌病而接受半腱肌切断术的马的病历。从记录中获取信号、病史、受影响的肌肉、约束方法、手术过程、短期结果以及并发症。通过与主人交谈，在术后至少6个月评估长期结果（步态和运动功能）。采用Pearson卡方统计分析比较约束方法和受影响的肌肉与总体结果。显著性设定为P < 0.05。
8匹马在站立镇静下进行半腱肌切断术，12匹马在全身麻醉下进行。随访期为9个月至10年。仅半腱肌受影响时，14匹马中有8匹步态有不同程度改善；半腱肌和半膜肌均受累时，6匹马中有4匹步态有不同程度改善（P = 0.11）。8匹在站立镇静下治疗的马中有6匹，12匹在全身麻醉下治疗的马中有6匹，其典型的纤维化步态有一定改善（P = 0.4473）。6匹在站立镇静下治疗的运动马中有5匹，9匹在全身麻醉下治疗的运动马中有6匹恢复到受伤前的运动水平。在站立镇静下治疗的马没有切口并发症；12匹在全身麻醉下治疗的马中有2匹出现切口引流。
对于患有纤维化肌病的马，无论在站立镇静还是全身麻醉下进行半腱肌切断术，步态改善情况相似。
