BACKGROUND: The anatomical structure of the pelvis is complex, and it is difficult to be fixed. Misplacement of screws can lead to severe complications. Therefore, exploring an efficient, simple, and economic individualized design of surgical staple parameters has become a key issue in the fixation of the acetabular anterior column fracture. OBJECTIVE: To design parameters on the anterior column of acetabulum fracture reconstruction plate internal fixation for preoperative design using CT scan data, and to compare with conventional steel plate fixation. METHODS: Forty patients with acetabular anterior column fracture were randomly assigned to two groups: digital design group (n=20) and conventional surgery group (n=20). The digital design group received pelvic CT scanning for data acquisition. Materialise Mimics Innovation Suite 16.0 software was used for digital simulation of anterior acetabular fracture plate fixation. The conventional surgery group received conventional steel plate fixation. Operation time, blood loss and healing time were compared between the two groups. Anatomic reduction ratio and hip function score were compared between the two groups at postoperative 16 weeks. RESULTS AND CONCLUSION: (1) Operation time, blood loss, healing time, anatomic reduction ratio and hip function score were better in the digital design group than in the conventional surgery group (P=0.00). (2) Results suggest that compared with the conventional surgery group, acetabular anterior column fractures of digital three-dimensional operation design has a good effect on reducing operation time and blood loss and elevating fixation effect, and can provide reference data for clinical diagnosis and treatment of acetabular anterior column fracture.%背景:骨盆解剖结构复杂,固定难度大,置钉失误会导致严重并发症.因此探索出高效、简单、经济的个体化设计手术置钉参数,成为髋臼前柱骨折固定的关键问题.目的:运用 CT 扫描数据对髋臼前柱骨折重建钢板内固定进行术前设计,并与常规钢板内固定手术进行疗效对比.方法:纳入髋臼前柱骨折患者40例,随机分为2组,数字化设计组20例,常规手术组20例.数字化设计组行骨盆CT扫描,获取数据,利用Materialise Mimics Innovation Suite 16.0软件对髋臼前柱骨折钢板内固定术进行数字化模拟;常规手术组进行常规钢板内固定手术.对比2组患者手术时间、失血量及骨折愈合时间,术后16周对比2组解剖复位比例及髋关节功能评分.结果与结论:①数字化设计组手术时间、失血量、骨折愈合时间、解剖复位比例、髋关节功能评分均优于对照组(P=0.00);②结果表明,与常规内固定手术相比,髋臼前柱骨折数字化三维术前设计对于减少手术时间、减少失血、提高内固定效果具有较好的作用,可为髋臼前柱骨折的临床诊治提供参考数据.
