进行研究的原因
缺乏关于构象对性能或骨科健康影响的科学数据和研究。
目标
目的：探讨跨栏赛马形态、损伤与成绩的关系。
方法
在两年多的时间里，对108匹国家狩猎赛马进行了跟踪，并记录了它们的医疗和表现数据。使用计算机化的运动分析系统在3D中测量构象。线性多元回归模型用于评估构型对比赛成绩的影响，逐步前向Logistic回归模型用于评估损伤风险的影响。
结果
增加下颌间宽度、肩关节屈曲角和髋角(髂骨和坐骨之间的夹角)对运动成绩有积极的影响。运动成绩随着掌指关节周长、后趾长度和外翻形态的增加而降低。患指浅屈肌腱损伤的风险随掌指关节角度和腕外翻形态的增加而增加。骨盆骨折的风险随着踝关节外翻形态的增加而增加，随着髋关节角度的增加而降低。
结论
外翻畸形被证明不利于运动能力或增加受伤的风险，可能会导致肌肉骨骼结构的更高负荷。髋关节角度是唯一对受伤风险和比赛成绩都有影响的参数。肌肉与骨盆的轴线对齐可能有利于力的传递，并减少肌肉对骨骼的弯矩。这项研究的统计能力有限，但它为计划更大规模的构象对性能和受伤风险的影响研究提供了必要的初步数据。
临床相关性
研究构象对成绩和受伤风险的影响可能有助于识别在赛马场上表现良好的个人，并避免受伤风险。
REASONS FOR PERFORMING STUDY
There is a lack of scientific data and studies on the effect of conformation on performance or on orthopaedic health.
OBJECTIVES
To investigate the relationship between conformation, injury and performance in racehorses used for racing over fences.
METHODS
Over 2 years, 108 National Hunt racehorses were followed and their medical and performance data recorded. Conformation was measured in 3D with a computerised motion analysis system. Linear multiple regression models were used to evaluate the effect of conformation on measures of race performance and stepwise forward logistic regression models to assess the effect on risk of injury.
RESULTS
An increase in intermandibular width, flexor angle of the shoulder joint and coxal angle (the angle between the ilium and ischium) was demonstrated to have a positive effect on performance. Performance decreased with increasing girth, length of the hind digit and valgus conformation of the metacarpophalangeal joint. The risk of suffering from superficial digital flexor tendon injury increased with increasing metacarpophalangeal joint angle and with carpus valgus conformation. The risk of pelvic fracture increased with valgus conformation of the tarsus and decreased with an increasing coxal angle.
CONCLUSION
Valgus deformation was demonstrated to be detrimental to performance or increased risk of injury, perhaps resulting in higher loads on musculoskeletal structures. The coxal angle was the only parameter to have an effect on both risk of injury and performance. An alignment of the muscles with the axis of the pelvis may be beneficial for force transmission and decrease the bending moment of the muscles on the bones. The statistical power of this study is limited, however it provides preliminary data necessary for the planning of a larger scale study on the effect of conformation on performance and risk of injury.
CLINICAL RELEVANCE
Studies of the effects of conformation on performance and risk of injury may aid in identifying individuals likely to perform well on the racecourse and avoid risks of injury.
