膝关节内骨折检查方法的选择(附142例报告)

目的　深入探讨X线平片在诊断膝关节内骨折中的地位。方法　对 1 4 2例膝关节内骨折患者的X线检查进行了分析研究 ,全组病例均摄膝关节正侧位 ,部分加摄左、右斜位 ,其中 2 4例还进行了CT检查。结果　首次检查X线正侧位平片发现骨折 1 2 7例 ,轴位及左、右斜位发现骨折 8例 ;第 2次后平片检查共检出骨折 1 39例 (另 3例可能因石膏固定骨折线观察不清 ) ;CT检查发现骨折 2 2例。结论　常规X线平片检查仍然是诊断膝关节内骨折的首选方法 ;CT检查可作为常规平片检查的补充 ,除发现少数隐匿性骨折外 ,还可进一步了解有无关节软骨及周边肌腱的损伤

Choice of Examination of Intra-knee Fracture (Attached 142 Cases)

Objective To investigate the status of X-ray plain film in the diagnosis of intra-knee fracture. Methods 142 cases of intra-knee fracture by plain film were retrospectively analyzed. All of the cases underwent radiograph for A.P., Lateral projections; some were added R. and L. oblique projections. 24 cases underwent CT scan. Results In the first examination, 127 cases were showed by plain film of A.P., Lateral projections, 8 cases by R. and L. oblique projections and axial view. In the second examination, 139 cases were showed by plain film (Fracture lines could not be showed in 3 cases due to the outside plaster), and 22 cases by CT scan. Conclusion Radiograph is the primary choice for intra-knee fracture. As the additional examination, CT scan can not only find the occult fracture but also the changes of articular cartilage and soft tissues.
