腓骨应力性骨折的X线诊断(附14例X线分析)

X-ray Expression of Stress Fibula Fracture: an Analysis of 14 Cases

目的：本文目的是对发生在排骨的应力骨折的X线诊断与其特殊的表现进行评价。材料与方法：收集资料完整的胖骨应力性骨折14例，对它们的X线征象及创伤性骨肿瘤样特殊X钱表现做了回顾性分析。结果：病灶多呈梭形丘状骨隆起；增生的骨膜与皮质融合，无相对分界；病灶边缘不规则，骨膜增生呈层状或花边状，类似骨肿瘤样改变；部分病例骨折线有向骨折两端移位趋向，晚期呈0．5～2cm的横行致密组织骨带；有55．5％的病例可显示周围软组织块影。结论：创伤性骨肿瘤样改变为胖骨应力性骨折的特殊X钱表现，易误诊为恶性骨肿瘤，在诊断中应密切结合临床。

Prupose: The purpose is appraising X - ray dignose and its special X - ray expression of stress fibula fracture. Meterials and methods: gathered 14 cases full material of stress fibula fracture, Analysed their X - ray signs and special X - ray expression of bone tumour, and discussed diagnose of the disease. Results: Below X - ray signs is the important basis for diagnose the disease; focus of infection is spindles - shape projection, hyperplasia periasteum mixed with cortex and no obviously boundary; edge of focus of infection is irregular, periasteum proliferation is layer or lace change like bone tumour; Lines of fracture has moved in some cases, with 0. 5 ~2cm transverse highdensity bone - band in advanced stage. Soft tissue block can be displayed in 55. 5 % cases. Conclusion: the change like traumatic bone tumour is special X - ray erpression of stress fibula fracture, and it could be misdiagnosised the illness as malignant tumour of bone, so we must integrate closely with clinical practice in diagnosis and differential diagnosis.
