INTRODUCTION
Chondromalacia of the trochlear notch and stress fracture of olecranon are uncommon injuries in the throwing athletes.
MATERIALS AND METHODS
We report an 18-year-old high school pitcher who had persistent postero-lateral elbow pain after a healed olecranon stress fracture of the right elbow. Diagnostic arthroscopy revealed chondromalacia of the trochlear notch.
RESULTS
After treatment with arthroscopic drilling and abrasion chondroplasty, he returned to competitive pitching 1 year later postsurgery. This rare association between chondromalacia and stress fracture of the olecranon has not been reported previously in the literatures.
CONCLUSION
Chondromalacia of the trochlear notch should be included as a differential diagnosis in evaluating athletes with persistent elbow pain after healed olecranon stress fractures.
引言
滑车切迹软骨软化和鹰嘴应力性骨折在投掷运动员中是不常见的损伤。
材料与方法
我们报告一名18岁的高中投手，其右肘鹰嘴应力性骨折愈合后仍有持续的后外侧肘部疼痛。诊断性关节镜检查显示滑车切迹软骨软化。
结果
经关节镜钻孔和磨削软骨成形术治疗后，他在术后1年恢复了竞争性投球。鹰嘴软骨软化与应力性骨折之间这种罕见的关联此前在文献中尚未见报道。
结论
在评估鹰嘴应力性骨折愈合后仍有持续肘部疼痛的运动员时，应将滑车切迹软骨软化纳入鉴别诊断。
