目的 探讨MSCT(多层螺旋CT)在 桡骨远端骨折分型评估中的应用价值， 比较X线与MSCT对不同分型桡骨远端骨 折的鉴别价值。方法 选取我院收治的80 例桡骨远端骨折患者作为研究对象，均 接受腕关节正侧X线摄片及MSCT检查，参 照AO标准作骨折分型，比较X线与MSCT在 不同分型桡骨远端骨折鉴别中的应用价 值。结果 80例患者经X线确诊为骨折者70 例(87.50%)，漏诊10例，其中A、B、C型 分别为26例(37.14%)、24例(34.29%)、 20例(28.57%)；MSCT共检出80例骨折， A、B、C型分别为19例(23.75%)、31例 (38.75%)、30例（37.50%）。MSCT检出率 为100.00%，明显高于X线的87.50%，差异 有统计学意义(χ2 =10.6667，P＜0.05)。 结论 MSCT对桡骨远端骨折的鉴别诊断及 分型更为细致及准确，对较复杂的关节内 骨折诊断价值较高。

Objective To investigate the application value of MSCT (multi-slice spiral CT) in the evaluation of distal radius fractures classification, and compare with the X-ray. Methods 80 patients with distal radius fractures in our hospital were selected as the study object. All patients underwent X-ray radiography scanning of the positive side of the wrist joint. Then, MSCT was performed. Referring to AO standard, fracture classification was performed. The application value of X-ray and MSCT in the differentiation of different types of distal radius fractures was compared. Results Among the 80 cases of patients, 70 cases (87.50%) were diagnosed as fractures by X-ray and 10 cases were missed diagnosed among whom patients with type A, B and C fractures were 26 cases (37.14%), 24 cases (34.29%) and 20 cases (28.57%) respectively; 80 cases with fractures were diagnosed by MSCT and patients with type A, B and C fractures were 19 cases (23.75%), 31 cases (38.75%) and 30 cases (37.50%) respectively. The detection rate of MSCT (100.00%) was significantly higher than that of X-ray (87.50%) with statistically significant (χ2 =10.6667, P＜0.05). Conclusion MSCT is more detailed and accurate for differential diagnosis and classification of distal radius fractures. It is of relatively higher value in the diagnosis of more complex intra-articular fractures.
