病理性骨折临床X线诊断(附57例分析)

本文分析了57例病理性骨折，病因以骨肿瘤引起的居首位，占35．1％，骨髓炎引起骨折的比例则明显下降，这是由于抗菌素的广泛应用使骨髓炎在早期即得到治疗的结果。总结了病理性骨折的特点；无外伤史或外伤轻微，部位在原发骨病部位，四肢骨骨折多无明显错位，观察骨断端改变对诊断原发骨病具有重要价值。脊柱骨折以胸腰段多见，与外伤性骨折相比有以下不同：椎体的压缩为上下缘向心性压缩多见，该椎体密度不高．往往合并有附件骨质破坏和其它骨质改变。

Clinic and radiologic diagnosis of pathologic fracture (Analysis of 57 cases )

Fifty seven cases of pathologic fracture were analyzed in this paper. Pathogenically, with bone tumor causing fracture occupied first place accounting for 35.1%, but the ratio in fracture caused by os-teomyelitis descended markedly-it was due to wide application of antibiotics as a result of ttpated oateomyeli-tis in early stage The characteristics of pathologic fracture are concluded as follows: no traumatic history or slight traurna: location in primary osteopathia; the most bones of the extremities have no evident malposi-tion; observirg the changes of severed bony ends as for diagnosing primary osteopathia has important value,The vertehral fracture is common in thoracic and lumbar segments compared with traumatic fracture has difference as follows; vertebral cormpression whose supperiot and inferior margins are cenripetal, are common,density of corn pressive vertebra is not rtigh, often associated with destruction in the bone of adnexa and other bony change.
