Five baseball pitchers, three college and two professional, with an average age of 24 years, exhibited pain between the acceleration phase and follow-through phase of the pitching motion. This caused the players to be unable to continue at the level of competition necessary to play. A significant osteophyte on the posteromedial aspect of the olecranon process was identified in all pitchers. This caused impingement with the articular wall of the olecranon fossa and often created an area of chondromalacia. The more commonly identified posterior osteophyte was present in all cases. However, if just this posterior osteophyte is removed, the described lesion will be missed, with resultant persistent disability. Surgical excision of the posteromedial osteophyte through a relatively atraumatic posterolateral approach allowed early return of function without morbidity. With an average follow up of 1 year, all of the pitchers returned for one full season at maximum effectiveness.
五名棒球投手，其中三名是大学生，两名是职业选手，平均年龄24岁，在投球动作的加速阶段和随挥阶段之间出现疼痛。这导致球员无法在比赛所需的水平上继续比赛。在所有投手中均发现尺骨鹰嘴后内侧有明显的骨赘。这导致与尺骨鹰嘴窝的关节壁发生撞击，并经常形成软骨软化区域。所有病例中均存在较常见的后侧骨赘。然而，如果仅切除这种后侧骨赘，将遗漏所描述的病变，导致持续残疾。通过相对无创的后外侧入路手术切除后内侧骨赘，可使功能早期恢复且无并发症。平均随访1年，所有投手均以最大效力回归完整赛季。
