The prevalence of joint hypermobility (JH) in patients with femoroacetabular impingement (FAI) and its association with outcomes is yet widely unknown. This study aimed to validate a self-reported version of the Beighton score for FAI patients, and to determine possible associations between JH and clinical and radiographic parameters.
The study included 55 consecutive patients (18 females, mean age 29 years) with a diagnosis of FAI. Patients completed a self-reported Beighton score before clinical assessment, and a clinician blinded to the self-reported form filled the examiner-based version. Reliability of the self-reported version was assessed using kappa statistics. The prevalence of JH and associations with clinical and radiographic parameters were determined.
The patients scored a mean of 2.6 points on the self-reported Beighton score. Agreement between self-assessment and examination was good to excellent for all single items and for the total score. Considering a Beighton score of ≥4 as cutoff for JH, the prevalence in the present cohort was 32.7% (50% of females and 24.3% of males). Significant associations were found between Beighton scores and hip joint motion. While no direct correlations were found between Beighton scores and the radiographic parameters; the group of patients with JH differed considerably from that without JH regarding gender distribution and FAI type.
The patient-oriented Beighton score proved to be feasible and reliable in FAI patients. The prevalence of JH in these patients seems to be high and future investigations about the association of JH with FAI and treatment outcomes are therefore warranted.
股骨髋臼撞击症（FAI）患者中关节活动度过大（JH）的患病率及其与预后的关系尚不明确。本研究旨在验证一种适用于FAI患者的自填式Beighton评分，并确定JH与临床及影像学参数之间可能存在的关联。
本研究纳入了55例连续诊断为FAI的患者（18例女性，平均年龄29岁）。患者在临床评估前完成自填式Beighton评分，一名对自填式表格不知情的临床医生填写基于检查者的版本。使用kappa统计量评估自填式版本的可靠性。确定JH的患病率及其与临床和影像学参数的关联。
患者自填式Beighton评分的平均得分为2.6分。自我评估与检查之间在所有单项及总分方面的一致性良好至优秀。将Beighton评分≥4作为JH的临界值，本队列中的患病率为32.7%（女性为50%，男性为24.3%）。发现Beighton评分与髋关节活动度之间存在显著关联。虽然未发现Beighton评分与影像学参数之间存在直接相关性；但JH患者组与非JH患者组在性别分布和FAI类型方面存在显著差异。
以患者为导向的Beighton评分在FAI患者中被证明是可行且可靠的。这些患者中JH的患病率似乎较高，因此有必要对JH与FAI及治疗结果之间的关联进行进一步研究。
