目的 探究髋关节病变患者应用 多层螺旋CT进行诊断的临床价值。方法 将我院120例髋关节病变患者给予CT扫 描，对其三维重建成像给予分析，观察 患者病变立体形态与周围结构关系，跟 常规X线结果实行对比。结果 X线检查的 患者，漏诊误诊率为61.66%，其中骨折 漏诊20例、结核漏诊10例、关节内骨碎 片误诊19例、关节内骨碎片漏诊25例； CT扫描，漏诊误诊率为16.67%，其中骨 折漏诊8例、结核漏诊5例、关节内骨碎 片误诊4例、关节内骨碎片漏诊3例。两 种检查方式数据比较，差异具有统计学 意义(P＜0.05)。结论 相较于常规X线有 限的髋关节病变显示，CT三维重建成像 技术可更直观地将病变以立体形态显示 出来，可明确地显示复杂骨折粉碎的程 度与移位，可作为手术入路与内固定的 影像学指导。且相对于X线检查，CT检查 对髋关节病变患者诊断更为精准，值得 临床应用。

Objective To explore the clinical value of MSCT in the diagnosis of hip joint lesions. Methods CT scan was given to 120 cases of patients with hip joint lesions in our hospital, and the three-dimensional reconstruction images were analyzed. To observe the relationship between the three-dimensional shape of the lesion and the surrounding structures, and to compare with the routine X-ray results. Results The misdiagnosis rate of patients undergoing X-ray examination was 61.66%, among which 20 cases were missed diagnosis of fracture, 10 cases were missed diagnosis of tuberculosis, 19 cases were misdiagnosed of joint bone fragments, and 25 cases were missed diagnosis of joint bone fragments; The misdiagnosis rate of patients undergoing CT scan was 16.67%, among which 8 cases were missed diagnosis of fracture, 5 cases were missed diagnosis of tuberculosis, 4 cases were misdiagnosed of joint bone fragments, and 3 cases were missed diagnosis of joint bone fragments. To compare the two kinds of examination data, the difference was statistically significant(P＜0.05). Conclusion Compared with conventional limited display of X-ray on hip joint lesions, CT three-dimensional reconstruction imaging technology displays three-dimensional shapes of lesions in more intuitive manner, may clearly display the degree and displacement of complex fracture, and may serve as an imaging guidance for surgical approach and internal fixation. And the diagnosis of CT examination on patients with hip joint lesions is more accurate when compared with that of X-ray, being worthy of clinical application.
