跟骨钉中钉内固定系统在跟骨骨折治疗中的优势

Advantages of nail-in-nail internal fixation system in the treatment of calcaneal fractures

探讨跟骨钉中钉手术较传统手术方式治疗跟骨骨折的优势.回顾性收集自2021年4月—2024年4月间跟骨骨折Sanders分型Ⅱ-Ⅲ型46例患者临床资料,根据治疗方式不同随机分为微创组(采用跟骨钉中钉内固定系统微创治疗,23例)和传统组(传统切开复位内固定治疗,23例),记录两组术前待术时间、手术时间、术后住院时间、术中出血量、手术并发症、术后1周、1月及1年功能恢复等情况,并进行比较,采用SPSS 23.0软件进行统计学分析,并于末次随访时按照Maryland足部评分系统评分.微创组与传统组患者在平均手术时间(78min vs 105min)、术中出血量(9.5ml vs 55ml)、Maryland足功能评分系统判定术后1周、术后1月及1年优良率(分别73.91%vs 43.48%,91.3%vs 78.2%,100%vs 91.3%)间差异均具有统计学意义(P<0.01).钉中钉内固定系统在跟骨骨折较以往传统切开复位内固定手术有明显优势,可缩短住院时间,术后功能恢复亦较良好,值得推广应用.

To explore the advantages of the nail-in-nail internal fixation system compared to traditional surgical methods in the treatment of calcaneal fractures,a retrospective analysis was conducted on the clinical data of 46 patients with Sanders classification II-III of calcaneal fractures from April 2021 to April 2024.Based on the treatment with minimally invasive nailin-nail internal fixation system or traditional open reduction and internal fixation.,the patients are divided into minimal invasive group(23 patients)and traditional open reduction group(23patients),comparing the preoperative waiting time,operation time,postoperative hospital stay,intraoperative blood loss,surgical complications,and functional recovery at 1 week,1 month,and 1 year postoperatively.The data were statistically analyzed using SPSS 23.0.and scored according to the Maryland Foot Rating System at the last follow-up.Minimal invasive group are superior to traditional open reduction group in average operation time(78min vs 105min),blood loss(9.5ml vs 55ml),and the excellent rates according to the Maryland Foot Score system on 1 week,1 month and 1 year postoperation(73.91%vs 43.48%,91.3%vs 78.2%,100%vs 91.3%,respectively).The differences between the two groups were statistically significant(P<0.01).The nail-in-nail internal fixation system shows significant advantages over traditional open reduction and internal fixation surgery in the treatment of calcaneal fractures,including shortened hospital stay and satisfactory postoperative functional recovery warranting broader application of this technique.
