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. |

纳入标准: |
1.年龄与诊断: 年龄在 18 至 75 周岁之间,且明确诊断为股骨颈骨折的患者。 2.治疗方案: 接受内固定手术治疗(如普通空心钉 CCS、股骨颈系统 FNS、动力髋螺钉 DHS 等)的患者。 3.随访配合: 同意接受术后至 12 个月的规范化影像学及功能随访的患者。 4.知情同意: 完全出于自愿参加本研究,并签署知情同意书的患者。 |
||||||||||||||||||||||
|
Inclusion criteria |
1.Age and Diagnosis: Patients aged between 18 and 75 years with a clear diagnosis of femoral neck fracture. 2.Treatment Plan: Patients who undergo internal fixation surgery (e.g., conventional cannulated screws (CCS), Femoral Neck System (FNS), Dynamic Hip Screw (DHS), etc.). 3.Follow-up Compliance: Patients who agree to undergo standardized imaging and functional follow-up from post-operation up to 12 months. 4.Informed Consent: Patients who participate in this study completely voluntarily and have signed the informed consent form. |
||||||||||||||||||||||
|
排除标准: |
1.年龄不符: 年龄小于 18 岁或大于 75 岁的患者。 2.治疗方式不符: 接受非手术保守治疗,或直接行人工髋关节置换手术的股骨颈骨折患者。 3.依从性差: 因身体、精神或其他客观原因,无法配合完成术后密集动态随访(如术后 1、2、3、6、12 个月)的患者。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1.Age Mismatch: Patients younger than 18 years or older than 75 years. 2.Treatment Mismatch: Patients with femoral neck fractures who receive non-surgical conservative treatment or undergo primary total hip arthroplasty. 3.Poor Compliance: Patients who are unable to comply with the intensive dynamic postoperative follow-up (e.g., at 1, 2, 3, 6, and 12 months postoperatively) due to physical, mental, or other objective reasons. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
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. |
