The purpose of this study is to evaluate the effect of pre-sliding of the femoral neck system (FNS) in the prevention of postoperative femoral neck shortening in femoral neck fractures.
This study was designed to retrospectively analyze data from 109 patients with femoral neck fractures who were admitted to a Level I trauma center between April 2020 and June 2022. Of these patients, 90 were followed up for more than 12 months. The study included 52 males and 38 females, with 35 cases of Garden I and II fractures and 55 cases of Garden III and IV fractures. The Harris Hip Score at 12 months postoperatively were recorded. The patients were divided into two groups based on their surgical records and postoperative radiography: the Pre-sliding group and the No-pre-sliding group. The purpose of this study is to analyze the role of pre-sliding in preventing femoral neck shortening, fracture healing time, degree of postoperative shortening, complications, and Harris Hip Score, and to make a comparison between the two groups.
All 90 patients were followed up for over one year after surgery. A statistically significant difference was observed in the preoperative Garden classification (P < 0.05). At 1 year after the operation, the shortening distance was 6.5 ± 6.4 mm in the No-pre-sliding group and 3.9 ± 3.4 mm in the Pre-sliding group. The Harris Hip Score were 88.7 (79.8, 93.5) in the No-pre-sliding group and 94.8 (87.7, 96.9) in the Pre-sliding group, with a statistically significant difference between the two groups (P < 0.05). Shortening was concentrated at 3 months postoperatively and reached a stable state within 6 months, with less persistent shortening occurring after 6 months. There was no statistically significant difference in the preoperative baseline data.
Pre-sliding of the FNS prevents postoperative shortening of the femoral neck and improves hip function as measured by the Harris Hip Score.
本研究旨在评估股骨颈系统（FNS）预滑动在预防股骨颈骨折术后股骨颈缩短方面的效果。
本研究旨在回顾性分析2020年4月至2022年6月期间在一级创伤中心收治的109例股骨颈骨折患者的数据。其中，90例患者接受了超过12个月的随访。研究包括52例男性和38例女性，Garden I型和II型骨折35例，Garden III型和IV型骨折55例。记录术后12个月时的Harris髋关节评分。根据手术记录和术后X线片将患者分为两组：预滑动组和非预滑动组。本研究旨在分析预滑动在预防股骨颈缩短、骨折愈合时间、术后缩短程度、并发症以及Harris髋关节评分方面的作用，并对两组进行比较。
所有90例患者术后均随访1年以上。术前Garden分级存在统计学显著差异（P < 0.05）。术后1年，非预滑动组的缩短距离为6.5±6.4mm，预滑动组为3.9±3.4mm。非预滑动组的Harris髋关节评分为88.7（79.8，93.5），预滑动组为94.8（87.7，96.9），两组间存在统计学显著差异（P < 0.05）。缩短集中在术后3个月，6个月内达到稳定状态，6个月后持续性缩短较少。术前基线数据无统计学显著差异。
FNS预滑动可预防股骨颈骨折术后股骨颈缩短，并通过Harris髋关节评分改善髋关节功能。
