摘要
目的:探讨获得型肢端骨质溶解的X线表现特点,提高对本病认识。方法:回顾性分析11例获得型肢端骨质溶解X线表现,其中糖尿病性5例,遗传性感觉神经根神经病2例,类风湿性2例,痛风性2例。结果:糖尿病性5例:骨质呈斑片状溶解2例,骨质完全溶解缺如1例,骨干一端骨质溶解呈"笔尖状"1例,骨干部分骨质溶解吸收、关节端骨质正常呈"图钉征"1例,5例溶解边缘的骨质均无硬化,溶解区附近骨质均无骨膜增生和骨皮质增厚。感觉神经根神经病2例:残留的骨端呈"平截状"和不规则缺损,骨质溶解完全缺如和关节脱位或半脱位、关节面糜烂;溶解边缘的骨质无骨膜增生和骨皮质增厚。类风湿性2例:残留的骨端呈"平截状"、"笔尖状"和不规则缺损;骨质明显脱钙,关节间隙明显狭窄。痛风性2例:趾骨骨质溶解的残留端呈"图钉状"和向心性溶解。结论:获得型肢端骨质溶解X线片主要表现为骨质溶解、吸收、缺如,无骨膜增生和骨皮质增厚,残留的骨端呈"平截状"、"笔尖状"、"图钉状"或不规则形,具有一定特征性。
Objective：To study the X-ray features of acquired type acroosteolysis in order to improve the understanding of this disease.Methods：X-ray findings of 11 cases with acquired type acroosteolysis were retrospectively analyzed.The 11 caeses included：5 cases of diabetes mellitus acroosteolysis（3 male,2 female,age from 59 to 69 years,mean age 63.8 years）;2 cases of hereditary sensory radicular neuropathy acroosteolysis（1 male,1 female,age 12 years and 21 years）;2 cases of rheumatoid nature（1 male,1 female,age 51 years and 40 years）;and 2 cases of gouty nature（2 males,age 74 years and 78 years）.Results：X-ray features of diabetic acroostaolysis included：patchy osteolysis（n=2）,complete osteolysis（n=1）,osteolysis at one end of diaphysis（n=1）,partial osteolysis at diaphysis with normal metaphysis（n=1）.There was no osteosclerosis at periphery of osteolysis,no periosteal proliferation and cortical thickening in all 5 cases.2 cases of sensory radicular neuropathy acroosteolysis：showed ＂flat cutting appearance＂ of bone end and irregular defect,complete disappearance of the bone,with dislocation and subluxation of the joint and erosion of joint surface,no periosteal proliferation and no thickening of bone cortex at dissolution edge of bone.Two cases of rhenmatoid acroosteolysis showed ＂flat cutting appearance＂ or ＂sharpened pencil appearance＂ of bone end and irregular defects with obvious decalcification and narrowing of joint space.Two cases of gouty acroosteolysis showed ＂punded out＂ appearance of phalanges and concentric lysis of bone.Conclusion：There are some characteristic X-ray features of acquired acroosteolysis,which may help for the diagnosis.
