摘　　要：目的研究计算机断层扫描(computed tomography,CT)对后踝关节内嵌入骨块形态学分析的价值。方法纳入2022年5月—2024年4月濮阳市人民医院收治的100例累及后踝的踝关节骨折患者为研究对象,回顾性分析患者临床资料,据CT检查中后踝关节内是否嵌入骨块分为未嵌入骨块组和嵌入骨块组,收集并比较两组患者基本信息,踝关节骨折位置、分型、累及部位及骨折块情况,后踝关节内嵌入骨块的位置、大小、形态及面积,行Pearson相关性分析,分析后踝关节内嵌入骨块面积与后踝骨折相关参数的相关性。结果CT检查结果显示,后踝关节内嵌入骨块患者71例,占比71.00%,后踝关节内未嵌入骨块患者29例,占比29.00%。两组性别、年龄、骨折位置、Lauge–Hansen分型、Danis-Weber分型等方面差异无统计学意义(P>0.05),两组Haraguchi分型及Mason分型差异有统计学意义(P<0.05)。后踝关节内嵌入骨块患者Haraguchi分型1型(87.32%)高于2型(8.45%)和3型(4.23%),差异有统计学意义(P<0.05),Mason分型以2A型(71.83%)高于1型(11.27%)、2B型(9.86%)和3型(7.04%),差异有统计学意义(P<0.05);嵌入骨块组患者累及内踝及胫骨腓切迹发生率36.62%、73.24%高于未嵌入骨块组6.90%、37.93%,累及胫骨腓切迹长度、后踝骨折块长度长于未嵌入骨块组,后踝骨折块面积大于未嵌入骨块组,差异有统计学意义(P<0.05);后踝关节内嵌入骨块位置外1/3骨块(63.38%)高于中1/3骨块(19.72%)和内1/3骨块(16.90%),差异有统计学意义(P<0.05);矢状径2~5 mm(46.48%)高于矢状径<2 mm(21.13%)和矢状径>5 mm(32.39%),差异有统计学意义(P<0.05);各形态骨折块发生率差异无统计学意义(P>0.05);后踝关节内嵌入骨块面积为4.71~196.41 mm2,平均(61.42±5.73)mm2。结论踝关节骨折分型为Haraguchi1型、Mason2A型,骨折累及内踝及胫骨腓切迹提示后踝关节内嵌入骨块发生风险较高,后踝关节内嵌入骨块面积与后踝骨折块�Objective To study the value of ComputedTomography(CT)for the morphological analysis of the embedded bone mass in the posterior ankle.Methods The retrospective study included 100 patients with ankle fracture involving the posterior ankle admitted to Puyang People's Hospital from May 2022 to April 2024 as the research objects.The clinical data of the patients were retrospectively analyzed.According to whether the posterior ankle had embedded bone mass in the CT examination,the patients were divided into the non-embedded bone mass group and the embedded bone mass group,and the basic information of the two groups was collected and compared.The location,type,involved location and fracture mass of the ankle,as well as the location,size,shape and area of the embedded bone mass in the back ankle were analyzed by Pearson correlation analysis to analyze the correlation between the area of the embedded bone mass in the back ankle and the related parameters of the posterior ankle fracture.Results CT results showed that there were 71 patients with embedded bone mass in the back ankle,accounting for 71.00%,and 29 patients with no embedded bone mass in the back ankle,accounting for 29.00%.There were no significant differences in gender,age,fracture location,Lauge-Hansen classification and Danis-Weber classification between the two groups(P>0.05),but there were significant differences in Haraguchi classification and Mason classification between the two groups(P<0.05).Haraguchi type 1(87.32%)was higher than type 2(8.45%)and type 3(4.23%)(P<0.05).Mason type 2A(71.83%)was higher than type 1(11.27%),type 2B(9.86%)and type 3(7.04%)(P<0.05).The incidence rates of medial malleolus and fibular notch of tibia involved in bone block embedding group were 36.62%and 73.24%higher than those in non-embedding group(6.90%and 37.93%).The length of fibular notch and posterior malleolar fracture involved in bone block embedding group was longer than that in non-embedding group,and the area of posterior malleolar fracture was larger than that in no
