摘要
目的:分析100例足舟骨副骨DR数字化摄影检查的影像学表现,以提高对该病的认识。方法 :100例患者均采用DR数字化X线机摄片,取常规足正斜位摄片,部分患者加照足内翻斜位及足侧位片。其中5例患者加做CT检查,1例加做MRI检查。结果:100例足舟骨副骨影像学表现较多样,主要分3型,Ⅰ型为嵌在胫后肌腱远端的籽骨11例,占11%。Ⅱ型是足舟骨的副骨化中心68例,占68%,此型中足舟骨与副骨对应面增生、硬化、毛糙24例,对应面下骨质囊变11例,足舟骨与副舟骨间隙增宽或倾斜2例,副舟骨碎裂1例。Ⅲ型是突出特别明显的足舟骨残留(角状足舟骨)型21例,占21%。100例中其中4例误诊为骨折。结论 :足舟骨副骨影像学表现较多样,对不规则副骨又有外伤史的患者最易误诊为新鲜骨折或陈旧性骨折,通过X线检查结合病史、体征、症状仔细观察分析可作出正确诊断,必要时可行CT、MRI进一步检查。
Objective：To analyze the image manifestations in 100 cases of scaphoid accessory bone by digitized radiography（DR） to improve the cognition on this disease.Methods：100 cases were performed DR by foot routine anteroposterior and oblique position,partial cases were added by foot varus oblique position and lateral position.5 cases were added to perform CT scan and 1 case was added to do MRI examination.Results：The imaging performances in 100 cases of scaphoid accessory bone were various and could be divided into 3 types.TypeⅠwas distal sesamoid embedded in the posterior tibial tendon in 11 cases,accounting for 11%t.Type Ⅱ was accessory bone ossification center of scaphoid in 68 cases,accounting 68%,including the proliferation,sclerosis and coarse of corresponding surface of scaphoid and accessory bone in 24 cases,bone cystic change under corresponding surface in 11 cases,the widened or tilted gap of scaphoid and accessory bone in 2 cases and accessory scaphoid osteomiosis in 1 case.Type Ⅲ was residual of scaphoid with particular protruding（hornlike scaphoid） in 21 cases,accounting for 21%.4 cases were misdiagnosed as fractures.Conclusion：Due to the various imaging performances of scaphoid accessory bone,the patients with irregular accessory bone and trauma history can be easily to be misdiagnosed as fresh or old fracture.DR radiography combined with history,signs and symptoms and careful observation can make the correct diagnosis,and perform CT or MRI further examinations if possible.
