目的:探讨螺旋CT扫描及三维重建技术在股骨颈骨折分型及治疗中的应用价值。方法:选择2010年5月~2013年5月期间我院收治的股骨颈骨折患者237例为研究对象,根据患者扫描检查方式的不同将其分为对照组(112例)和观察组(125例),对照组患者行髋关节X线正位扫描,观察组行髋关节正位64排螺旋CT扫描,两组均根据扫描结果进行分型并制定相应的治疗方案,比较两组患者骨折内固定手术后2年的股骨头坏死率及骨折不愈合率。结果:两组行骨折内固定手术比例比较,差异无统计学意义(P>0.05);术后2年,对照组股骨头坏死5例(22.73%),骨不连6例(27.27%);观察组股骨头坏死1例(3.70%),骨不连1例(3.70%),观察组患者股骨头坏死率及骨折不愈合率均显著低于对照组,差异均有统计学意义(P<0.05)。结论:螺旋CT扫描及三维重建成像能够全面、准确显示股骨颈骨折的损伤情况,有助于骨折的正确分型和治疗方法的选择,改善预后。
Objective: To investigate the value of spiral CT and three-dimensional reconstruction in the classification and treatment of femoral neck fracture. Methods: A total of 237 patients with femoral neck fracture treated in our hospital from May 2010 to May 2013 were selected as the control group (112 cases) and the observation group (125 cases ). The patients in the control group underwent positive X-ray scan of hip joint. The observation group received 64-slice spiral CT scan of the hip joint. The two groups were classified according to the scan results and the corresponding treatment plans were made. The fracture fixation Femoral head necrosis rate and nonunion rate after 2 years of surgery. Results: There was no significant difference between the two groups in the rate of fracture fixation (P> 0.05). In the two years after operation, the control group had 5 cases of femoral head necrosis (22.73%) and 6 cases of nonunion (27.27%). One case (3.70%) of femoral head necrosis and one case of nonunion (3.70%) were observed in observation group. The necrosis rate of femoral head and nonunion rate in observation group were significantly lower than those in control group (P < 0.05). Conclusion: Spiral CT scan and three-dimensional reconstruction imaging can comprehensively and accurately show the damage of femoral neck fractures, which is helpful for the correct classification of fractures and the selection of treatment methods and prognosis.
