| 目的分析旋后外旋型踝关节骨折病人的胫腓骨远端 CT值情况。方法回顾性分析中国人民解放军联勤保障部队第 901医院 2016年 1月至 2018年 12月收治的 32例旋后外旋型踝关节骨折病人的病例资料，比较单踝、双踝和三踝骨折三种类型病人胫腓骨远端骨松质 CT值的差异。结果胫腓骨 CT值从高到低分别为单踝( 327.30±25.31)HU、双踝( 256.42±27.47)HU和三踝骨折( 199.36±34.62)HU，组间均差异有统计学意义。受试者工作特征曲线显示 CT值为 282 HU时区分单踝和双踝骨折的曲线下面积为 0.967(P=0.011)CT值为 220 HU时区分双踝和三踝骨折的曲线下面积为 0.889(P=0.004)。结论旋后外旋型踝关节骨折的不同类型病人的胫，腓骨远端 CT值差异较大，在诊断和治疗中需要注意。 |

| Objective To analyze the CT value of distal tibia and fibula in patients with supination external rotation ankle fracture. Methods The clinical data of 32 patients with supination external rotation ankle racture in the 901th Hospital of PLA Joint LogisticsSupport Force from January 2016 to December 2018 were analyzed retrospectively. The differences of CT values in cancellous bone ofdistal tibia and fibula among single, double and triple ankle fracture were compared.Results The CT values of tibia and fibula rangedfrom high to low in single ankle(327.30 ± 25.31)HU, double ankle(256.42 ± 27.47)HU and triple ankle fractures(199.36 ± 34.62)HU,respectively. There were significant differences between each two groups. The receiver operator characteristic curve showed that the area under the curve to distinguish single ankle fracture from double ankle fracture was 0.967 with CT value 282 HU (P=0.011), and the area under the curve to distinguish double ankle fracture from triple ankle fracture was 0.889 with CT value 220 HU(P=0.004).Conclu? sion The CT value of distal tibia and fibula in different types of patients with supination external rotation ankle fracture are quite different, which should be paid attention to in diagnosis and treatment. |
