少年举重运动员膝关节形态结构的X线研究

X-ray Anatomical Study of Knee joint on Young Weight-lifting Athletes

本文对少年举重运动员与不从事专项运动者的左右膝关节正位X线片进行了形态学观察。结果表明:举重运动员的股骨下端与胫骨上端内外侧髁肥大突出,骨小梁的压力曲线增粗,排列密集,清晰;膝关节股外侧关节面与胫骨外侧髁上关节面间隙较大;髁间隆起略大;股骨角与胫骨角均在正常值范围内,未出现膝内、外翻现象。上述结果可作为举重运动训练及临床诊断的参考。

A comparative morphological observation was carried out on the knee joints of young weight-lifting athletes and the non-athletes by means of X-ray photography.The results showed that in weight-lifting athletes,both the lower end of the femur and the lateral and medial condyles as well as the inter condylar eminence of tibia were larger than those of the non-athletes;The trabeculae of them became thicker and denser.The potential space between the superolateral articular surface of tibia and the articular surface of the lateral condyle of femur was wider in the athletes than in the non-athletes.However,the femoral and tibial angles were normal in both groups.
