研究目的:

本研究旨在前瞻性探讨股骨颈骨折内固定术后股骨颈短缩(FNS)的发生规律及其影响因素 。具体目的包括: 1.描述股骨颈骨折术后12个月内股骨颈短缩的发生率及演变曲线 。 2.分析患者自身因素(如体重/BMI、骨密度)、骨折类型、内固定类型及固定方式对短缩速度和总量的影响 。  

Objectives of Study:

This study aims to prospectively investigate the occurrence patterns and main influencing factors of femoral neck shortening (FNS) following internal fixation of femoral neck fractures. The specific objectives are: 1.To describe the incidence and evolutionary curve of femoral neck shortening within 12 months postoperatively. 2.To analyze the effects of patient-specific factors (such as weight/BMI and bone mineral density), fracture types, internal fixation types, and fixation configurations on the rate and total amount of shortening.

本研究制定了标准化的电子病例记录表(eCRF)以收集受试者的基线、骨折特征、动态影像及随访预后数据。数据采集与管理依托基于 Lovable 定制开发的云端电子数据采集系统(EDC)。各协作分中心研究人员通过独立账号登录,实现多中心实时数据录入与影像资料上传。所有受试者数据均采用去隐私化编码录入并加密存储,由牵头总中心定期进行集中盲法核查与质量监控。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

This study utilizes a standardized electronic Case Report Form (eCRF) to collect baseline, fracture characteristics, dynamic radiological, and follow-up data. Data capture and management are conducted using a custom cloud-based Electronic Data Capture (EDC) system built with Lovable. Researchers from participating centers log into the system with dedicated accounts for real-time multicenter data entry and image uploading. All participant data are de-identified, encrypted, and subjected to regular centralized blinded verification and quality control by the coordinating center.
