目的：分析疲劳性跖骨骨折的超声表现，探讨超声在早期诊断和随访中的临床价值。方法回顾性分析我院超声科36例经过X线和CT随访证实疲劳性跖骨骨折患者的临床表现及超声声像图特征。结果36例患者均为第2或第3跖骨干不全性骨折，超声随访3个月，骨皮质由增厚，边缘毛糙，呈针状或线状低回声，逐渐演变为表面光滑，丘状或半球形隆起，彩色多普勒早期见骨膜及软组织内血流信号丰富，在骨痂形成期，骨皮质及周围组织内可见条状或迂曲状丰富血流信号，在改造塑形期，血流信号减少、消失。结论超声能观察骨皮质连续性，显示疲劳性骨折愈合过程中骨痂动态变化及血流灌注特征。
目的：分析疲勞性蹠骨骨摺的超聲錶現，探討超聲在早期診斷和隨訪中的臨床價值。方法迴顧性分析我院超聲科36例經過X線和CT隨訪證實疲勞性蹠骨骨摺患者的臨床錶現及超聲聲像圖特徵。結果36例患者均為第2或第3蹠骨榦不全性骨摺，超聲隨訪3箇月，骨皮質由增厚，邊緣毛糙，呈針狀或線狀低迴聲，逐漸縯變為錶麵光滑，丘狀或半毬形隆起，綵色多普勒早期見骨膜及軟組織內血流信號豐富，在骨痂形成期，骨皮質及週圍組織內可見條狀或迂麯狀豐富血流信號，在改造塑形期，血流信號減少、消失。結論超聲能觀察骨皮質連續性，顯示疲勞性骨摺愈閤過程中骨痂動態變化及血流灌註特徵。

ObjectiveTo observe the ultrasonic manifestation of metatarsal fatigue fractures andprobe into the clinical values of ultrasonic diagnosis and folow-up to the disease.Methods The clinical data and sonographic features of 36 cases with metatarsal fatigue fracture confirmed by X-ray and CT were analyzed retrospectively.Results Al the subjects in this study were metatarsals insufficiency fractures located in the second or third diaphysis, 2D-ultrasound found microfracture in the cortex and the periosteal elevation by increased vascularity in the early stage,during the 3-month folow-up,thickened cortex and calus shown as the shape of mushroom or cauliflower and a great amount of neovascularisation were visualised with color Doppler flow imaging,the cortex surface became gradualy changing from rough to smooth and obvious posterior shadows were observed with the ilness progression.Conclusion UItrasonography could be used to detect the cortical continuity,calus characteristics and blood flow perfusion of fatigue fracture in the different damage stages.
