进行研究的原因：有关于比赛的数量和评价结果的时期是有限的信息，这对评估SDF肌腱炎treatments.Objective：为了评估再损伤率和比赛性能的纯种赛马，维持SDF肌腱炎与匹配的controls.Study design：临床记录和比赛历史的401匹赛马与SDF肌腱炎的第一次发生超声诊断。对照组是相同的年龄，性别和马匹训练在同一个建立在受伤的情况下，马匹和教练报告说，马没有以前的SDF肌腱损伤或treatment.Results：百分之八十的情况下和对照组的马匹返回到比赛后的日期受伤，并在3年内的治疗再受伤的比例为53%。与对照马（平均值= 17.0 lbs;范围= 0-79）相比，病例马（平均值= 9.6 lbs;范围= 0-75）中比赛后评分（（最大值））（RPR（最大值））和给药日期前即刻比赛中比赛后评分的差异显著较小。损伤后未观察到RPR（最大值）显著降低。没有发现的情况下，对照组和对照组之间的马返回到赛车和比赛3倍，但控制马匹更有可能竞争5比赛治疗后的日期比case horses.Conclusion和临床相关性：损伤与个人的损伤前的最高性能水平和返回到赛车和完成3场比赛是没有用的指标的结果与SDF肌腱炎的马。使用损伤后比赛次数评估赛马群体中SDF损伤马的结局需要至少5场损伤后比赛作为有用指标。此外，治疗后3年训练的马群中的再损伤比例。
P>Reasons for performing study:There is limited information regarding the number of races and the period for evaluation of outcome which is critical for assessment of SDF tendonitis treatments.Objective:To evaluate the re-injury rate and racing performance of Thoroughbred racehorses that sustain SDF tendonitis in relation to matched controls in terms of number of races post treatment and maximum racing performance ratings before and after injury.Study design:Clinical records and racing histories of 401 racehorses with a first occurrence of SDF tendonitis diagnosed by ultrasonography. Controls were of the same age, sex and were horses training in the same establishment at the time of injury as the case horses and where the trainer reported that the horse had not had a previous SDF tendon injury or treatment.Results:Eighty percent of both case and control horses returned to racing after the date of injury, and the re-injury proportion within 3 years of treatment was 53%. The difference in Racing Post Rating((max)) (RPR(max)) and the Racing Post Rating in the race immediately before the treatment date was significantly smaller in case horses (mean = 9.6 lbs; range = 0-75) compared to control horses (mean = 17.0 lbs; range = 0-79). No significant decrease in RPR(max) was noted post injury. No difference between case and control horses was found for return to racing and racing 3 times, but control horses were significantly more likely to compete 5 races post treatment date than case horses.Conclusion and clinical relevance:Injury was associated with an individual's pre-injury maximum performance level and return to racing and completion of 3 races are not useful indicator of the outcome of horses with SDF tendonitis. The assessment of the outcome of horses with an SDF injury in a population of racehorses using the number of races post injury requires a minimum of 5 races post injury to be a useful indicator. Further, a re-injury proportion in a population of horses in training for 3 years post treatment.
