With millions of athletes participating in baseball in the United States annually, overuse injuries are common occurrences. Epidemiological studies, including surveys of orthopaedic surgeons, coaches, and athletes, indicate that injuries such as those to the ulnar collateral ligament are increasing in incidence. Many risk factors for throwing injuries have been proposed-including the immature skeleton, throwing mechanics, glenohumeral internal rotation deficit, pitch type, velocity, and counts-but little evidence is available to support the majority of these factors. Recent studies have shown that pitch volume and overuse are central factors that lead to shoulder and elbow injuries in the young throwing athlete. Pitching while fatigued and in spite of arm pain has also been implicated.
每年有数百万的运动员参与到棒球运动中，因此过度使用导致的损伤很常见。流行病学研究，包括对矫形外科医生、教练和运动员的调查，都表明类似的尺侧副韧带损伤的发生率正在上升。许多投掷伤的危险因素已经被提出，包括不成熟的骨骼、投掷力学、盂肱关节内旋不足、投球类型、速度和投球次数，但很少有证据支持这些因素中的大多数。最近的研究表明，投球量和过度使用是导致年轻投掷运动员肩部和肘部受伤的核心因素。即使手臂疼痛，疲劳时投球也与此相关。
