摘要
目的:探讨急性青少年胫骨结节撕脱性骨折的影像学诊断价值。方法:回顾性分析经手术证实的6例(都为男性)急性青少年胫骨结节撕脱性骨折患者资料,其中2例右侧,4例左侧。除1例为跌倒致伤外,其余5例为运动损伤。X线平片检查6例,CT平扫2例,MRI平扫3例。结果:X线平片表现,根据Ogden’s分型,1例ⅠB型,1例ⅡA型、2例ⅡB型、1例ⅢA型、1例ⅢB型;6例均有髌骨上移征象。CT表现,2例ⅡB患者显示骨碎块移位,髌骨往上移位,其中1例合并髌骨陈旧性骨折。3例合并髌韧带撕裂,1例ⅡB型骨折合并髌韧带撕裂患者CT、MRI显示髌韧带肿胀,扭曲,T1WI、T2WI髌韧带信号增高。结论:X线平片是诊断急性胫骨结节撕脱性首选的影像方法,CT对骨折分型也有一定的帮助。怀疑有合并髌韧带、半月板等软组织损伤时,MRI具有重要诊断价值,对治疗方案的选择具有指导作用。
Objective： To investigate the diagnostic value of X-ray, CT and MRI in acute avulsion fracture of tibial tuberosity in adolescents. Method： 6 cases （all male） of acute avulsion fracture of tibial tuberosity in adolescents confirmed by operation were analyzed retrospectively. Of them, 2 cases and 4 cases were right side and left side, respectively. 5 cases were caused by sport injury and 1 case was tumble injury. 6 cases all received X-ray examination, 2 cases underwent plain CT scans and 3 cases underwent conventional MRI scans. Results： According to Ogden＇s classification, the case of type I B, IIA, IIB, ILIA, IIlB were 1, I, 2, 1, 1 respectively on X-ray film. The sign of patella on the shift was found in all cases. CT scanning showed displacement of bone fragmenets and patella on the shift in 2 cases of type II B, and 1 case was complicated with old fracture of patella. 3 cases were complicated with patellar tendon ruptures. In 1 case of type IIB complicated with patellar tendon ruptures, CT and MR1 showed that patellar tendon was swollen and twisted, and was high signal intensity on TIWI and T2WI. Conclusion： X-ray was the first choice for imaging diagnosis in acute avulsion fracture of tibial tuberosity and CT is helpful for the fracture classification. MRI has an important value in diagnosis and guiding treatment when suspected that complicated with soft tissue injuries, such as patellar tendon, meniscus tear and so on.
