Upper-extremity trauma has been extensively studied in traditional sports to reduce predisposition to injury. Limited attention has been directed toward nontraditional, high-collision sports such as rodeo. Therefore, the purpose of this study was to quantify radiographic changes of the upper extremity in collegiate rodeo athletes after seasonal competition.
After written informed consent, 25 male roughstock athletes (age = 21.0 +/- 1.4 yr; height = 174.5 +/- 5.7 cm; weight = 73.0 +/- 5.9 kg) competing in the College National Finals Rodeo reported for standard anteroposterior and lateral x-rays of both arms (hand/wrist, forearm, and elbow).
Radiographs revealed 82 total abnormalities involving both left and right extremities of all athletes. Hand/wrist findings included 24 fractures (19 healed, 5 nonunion) involving scaphoid, styloid, interphalangeal, phalanx, and various metacarpals. Fourteen cases of degenerative joint disease (scaphoid/radius, scapholunate, triangulofibrocartilage, and carpometacarpal), joint calcification, dorsal instability, and scapholunate dissociation were observed. Forearm findings included ulnar cortical thickening, healed stress fractures, and plates/screws. Elbow findings revealed ulnar/humeral degeneration, calcification, posterior olecranon tip fracture, traction spurs, and joint space narrowing with loose bodies.
Findings indicate a significant amount of radiographic evidence of repetitive trauma to the upper extremity in this sport. Development and mandatory use of effective external bracing beyond existing techniques at the collegiate level of competition should be encouraged.
在传统体育项目中，上肢创伤已得到广泛研究，以降低受伤倾向。对于诸如牛仔竞技等非传统的高碰撞性运动，关注较少。因此，本研究的目的是量化大学牛仔竞技运动员在赛季比赛后上肢的影像学变化。
在获得书面知情同意后，25名参加大学全国决赛牛仔竞技的男性粗野竞技运动员（年龄 = 21.0 +/- 1.4岁；身高 = 174.5 +/- 5.7厘米；体重 = 73.0 +/- 5.9千克）前来进行双臂（手/腕、前臂和肘部）的标准前后位和侧位X线检查。
X线片显示所有运动员的左右上肢共有82处异常。手/腕部的检查结果包括24处骨折（19处已愈合，5处骨不连），涉及舟骨、茎突、指间关节、指骨和各种掌骨。观察到14例退行性关节病（舟骨/桡骨、舟月关节、三角纤维软骨和腕掌关节）、关节钙化、背侧不稳定和舟月关节分离。前臂的检查结果包括尺骨皮质增厚、愈合的应力性骨折以及钢板/螺钉。肘部的检查结果显示尺骨/肱骨退变、钙化、尺骨鹰嘴尖部骨折、牵引骨刺以及伴有游离体的关节间隙变窄。
研究结果表明，在这项运动中，上肢存在大量重复性创伤的影像学证据。应鼓励在大学比赛级别开发并强制使用超越现有技术的有效外部支撑装置。
