Although an association between femoroacetabular impingement (FAI) and sports has been reported, there are no reports regarding arthroscopic findings of osteoarthritis due to FAI in adolescent unicyclists.
We present three cases of experienced unicyclists with coxarthrosis at puberty (three girls aged 17, 15, and 12 years). All three girls had bone morphology characteristics of FAI (two unicyclists with cam-type FAI and one with mixed-type FAI). None of them had a history of trauma or abnormal blood test result. The patients underwent hip arthroscopic surgery and intra-articular evaluation/treatment (acetabular labral repair, synovectomy, bone marrow stimulation [microfracture], and capsular closure). Arthroscopic findings included severe and extensive cartilage and acetabular labrum damages. After surgery, only two patients were able to return to competition. The characteristics of the unicycle competition may have led to puberty coxarthrosis due to FAI.
Hip joint symptoms in adolescent unicyclists have a risk for causing severe and extensive damages to the labrum and articular cartilages at an early stage, thereby requiring preventive and attention-seeking measures.
尽管已有报道称股骨髋臼撞击症(FAI)与运动之间存在关联,但关于青少年独轮车骑行者中因FAI导致骨关节炎的关节镜检查结果尚无相关报道。
我们呈现了三例青春期患有髋关节病的经验丰富的独轮车骑行者(三名女孩,年龄分别为17岁、15岁和12岁)。所有三名女孩均具有FAI的骨形态特征(两名独轮车骑行者为凸轮型FAI,一名为混合型FAI)。她们均无外伤史或血液检查异常结果。患者接受了髋关节镜手术及关节内评估/治疗(髋臼盂唇修复、滑膜切除术、骨髓刺激[微骨折]和关节囊闭合)。关节镜检查结果包括严重且广泛的软骨和髋臼盂唇损伤。术后,只有两名患者能够恢复比赛。独轮车比赛的特点可能导致了青春期因FAI引起的髋关节病。
青少年独轮车骑行者的髋关节症状有早期导致盂唇和关节软骨严重广泛损伤的风险,因此需要采取预防和关注措施。
