摘要
本文用临床流行病学方法调查了我国111名优秀男子排球运动员髌骨软骨软化症(CP)的患病情况及与Q角的关系,发现CP患病率达39.6%,占膝伤首位。111名男排队员的平均Q角为13°±3°,其中44例患者的Q角为14°±3°,较未患CP者的Q角12°±3°明显为大。CP患病率与Q角大小密切正相关,r=0.825。认为Q角在发育成熟的个体较恒定,建议作为运动员选材的指标之一。同时也探讨了Q角测量方法、认为体表定位Q角测量是一种简单易行,精确可靠的方法。选取髌骨中点是保证精确测量的关键。
In this paper, the relationship between Q-angle (QA) and occurrence of chondromalacia patellae (CP)was studied in 111 Chinese elite male volleyball players using the method of clinical epidemiology. The studyshowed that the incidence of CP was 39.6% and it suggested that CP was the most frequently seen sportsinjuries in the knee joint among volleyball players. No significant difference was found between left andright sides regarding the CP incidence, but the incidence increased obviously with the age and the length ofathletic career. The incidence of enthesiopathy at upper pole of patellae was 19.8% and was just next toCP, which should be in high alert. The average QA of total male volleyball players was 13°±3°, while average QA in players with CP(14°±3°) was significantly greater than that in players without CP (12°+3°). The greater the QA was, thehigher the incidence of CP appeared. The relationship could be expressed with a linear regression equation:y = 3.224x - 0. 1, with a correlative coefficient: r = 0.825. Therefore QA could be considered as a referenceindex for prospective volleyball players selection. Players with sound QA ought to be selected more prefera-ble than those with too large QA (over 18°). It was suggested that superficial measurement of QA was aneasy and reliable method, also to localize the center of patellae accurately was quite important in both super-ficial and roentgenographic measurements of QA.
