OBJECTIVE
To assess changes in elbow ulnar collateral ligament length in college baseball pitchers over the course of a single season.
DESIGN
Cohort Feasibility Study.
METHODS
Diagnostic ultrasound was used to assess both the dominant and non-dominant medial elbow joint space in four pitchers and five fielders and compared to in-game pitching data. Shoulder, elbow, wrist, hip, knee, and ankle range of motion measurements were also taken.
RESULTS
Mean trends for both the pitching and fielding groups showed no increases in dominant arm medial elbow joint space. Range of motion (ROM) increases were seen in both groups, and neither ultrasound nor ROM changes correlated to number of pitches thrown.
CONCLUSION
It is feasible that shoulder and hip range of motion changes directly affect stresses at the elbow in baseball pitching (Wilk et al., 2014) (Sauers et al., 2014). Further research is needed to investigate whether UCL injuries are related to increased laxity of the ligament.
目的
评估大学棒球投手在单个赛季中肘部尺侧副韧带长度的变化。
设计
队列可行性研究。
方法
使用诊断超声评估4名投手和5名外野手优势侧和非优势侧内侧肘关节间隙，并与比赛中的投球数据进行比较。还测量了肩、肘、腕、髋、膝和踝关节的活动范围。
结果
投手组和外野手组的平均趋势均显示优势侧手臂内侧肘关节间隙没有增加。两组的活动范围（ROM）均有增加，且超声检查结果和ROM变化均与投球次数无关。
结论
肩部和髋部活动范围的变化直接影响棒球投球时肘部的应力是可行的（威尔克等人，2014年）（索尔等人，2014年）。需要进一步研究来调查尺侧副韧带损伤是否与韧带松弛增加有关。
