摘要
目的探讨MRI对评价体操运动员下肢骨关节损伤的价值。方法回顾性分析18例体操运动队员45次下肢MR检查结果.其中4例与X线平片、CT检查结果比较。结果45次MR检查包括足部3例11次、踝关节6例13次、膝关节4例6次以及髋关节6例15次。所有足舟骨均变扁.并出现片状水肿,10次(90.91%)显示骨折线。所有胫骨远端骨骺变扁、碎裂,9次(69.23%)内踝、8次(61.54%)胫骨远端骨骺内出现大片水肿。3次(50.00%)股骨外侧髁、4次(66.67%)胫骨近端骨骺斑片状水肿;5次(83.33%)显示半月板退变,以内侧半月板后角几率最高(4/6)。5例13次股骨头变扁,并显示片状水肿;1例行9次检查显示了股骨头从损伤塌陷到逐渐恢复的过程。结论MRI检查可以早期全面地显示体操运动员运动损伤的全貌,为早期进行康复提供客观依据。
Objective To observe value of MRI for gymnasium athletes lower extremity sports injuries.Methods MRI of 18 athletes were analyzed retrospectively,and 4 athletes of them were compared with findings of X-ray and CT examinations.Results Forty-five MR examination were composed of 11 examination of feet of 3 cases,13 examination of ankles of 6 cases,6 examination of knees of 4 cases and 15 examination of 6 cases of hips.All navicular bones displayed flattened and bruised,with fracture of 10 examination（90.91%）.The distal epiphyses of tibial bone became flattened and smashed,with patchy edema of 9 examination（69.23%）of internal ankle and 8 examination（61.54%）of distal epiphysis of tibial bone. Patchy edema was detected within lateral condyle of femoral bone of 3 examination（50.00%）,and proximal epiphyses of tibial bone of 4 examination（66.67%）.Meniscus degeneration was found in 5 examination（83.33%）,with the most prevalence rate（4/8）of posterior horn of medial meniscus.For hip joint,femoral heads of 13 examination of 5 athletes changed flattened,with varying patchy edema.Nine MR examination of one athlete revealed the whole evolving course from acute sports injury to eventual recovery.X-ray and CT could only discover fractures and bone sclerotization,without detection of bone marrow edema.Conclusion Lower extremity MRI can early discover the sports injuries outlines and provide objective evidences for in-time healing and prevention of major complications.
