目的    探讨跗骨窦切口海马钢板内固定治疗Sanders Ⅱ、Ⅲ型跟骨骨折术后并发症的影响因素。  方法    回顾性分析自2021年01月至2022年4月跗骨窦切口海马型钢板内固定治疗的85例Sanders Ⅱ、Ⅲ型跟骨骨折患者。跟据术后并发症情况，将所有患者分为并发症组与无并发症组。根据患者临床结局分为两组：并发症组和非并发症组。非并发症组定义为术后6个月内恢复到基线功能，能正常工作和日常活动，无持续镇痛药需求。并发症组定义为，骨折并发症需再住院治疗，使用助行器和持续镇痛药物。应用单因素以及多因素方法分析跗骨窦切口海马钢板内固定治疗跟Sanders Ⅱ、Ⅲ型骨骨折并发症的危险因素。  结果    多因素 Logistic 回归分析指出骨折至手术时间、Sander Ⅲ型、术后B?hler角、DVBA是并发症发生的独立危险因素。年龄与术后并发症发生无关。  结论   临床医师应警惕Sander Ⅲ型、术后B?hler角恢复不佳、骨折至手术时间长的跟骨骨折患者出现术后并发症。 

Objective    To investigate the factors influencing the postoperative complications of internal fixation of the tarsal sinus incision hippocampal plate for Sanders type II and III calcaneal fracture. Methods    A retrospective analysis of 85 patients with Sanders type II and III calcaneal fracture treated with tarsal sinus incision hippocampal plate internal fixation from January 2021 to April 2022 was performed. According to the postoperative complications, they were divided into a complication group and non-complication group. The non-complication group was defined as recovery to baseline function within 6 months after operation, doing normal work and daily activities, and no continuous need for analgesics. The complication group was defined as fracture complication requiring re-hospitalization, the use of a walking aid, and continuous analgesics. The risk factors for complications of Sanders II and III bone fractures were  analyzed by univariate and multifactorial methods.    Results    Multi-factorial logistic regression analysis result showed that time from fracture to surgery, Sander type III, postoperative B?hler angle, and DVBA were as independent risk factors for complications. Age was not associated with the development of postoperative complications.    Conclusions    Clinicians should be alert for postoperative complications in patients with Sander type III, poor postoperative B?hler angle recovery, and long fracture-to-operation time for calcaneal fracture.
