研究目的:

1. 技术与产品研发目标 临床验证:验证“无接骨板内固定新技术”治疗踝关节骨折的近期总体功能(主要终点)非劣效于金标准“接骨板内固定技术”,同时评估并证实本系统在促进骨折快速愈合、降低术后疼痛、减少软组织并发症及内固定物二次取出率等次要终点方面的显著优效性与独特优势。 产品开发与迭代:依托本项目的临床研究与生物力学验证,完成“微创动态稳定应力刺激系统”核心组件的研发、优化与转化。具体包括开发应力响应式骨块钉以及温度响应式形状记忆合金促骨愈合钉和二次加压钉。 2. 智能评估与康复指导目标 依托RCT高质量的临床与影像数据,开发并验证一套基于人工智能深度学习的CT影像骨折愈合智能评估系统。提供客观、精准、可量化的骨折愈合评价新方法,为患者提供个性化的精准康复方案,填补“精准康复”领域的空白。  

Objectives of Study:

This project aims to clinically validate that the novel plate-free internal fixation technique for ankle fractures is non-inferior to the current gold-standard plate fixation technique in terms of short-term overall functional outcomes, while demonstrating significant superiority and distinctive advantages in accelerating fracture healing, reducing postoperative pain, minimizing soft-tissue complications, and lowering the rate of secondary implant removal. Based on the clinical investigation and biomechanical validation, the project will further advance the development, optimization, and translational application of the core components of a minimally invasive dynamic stabilization stress-stimulation system, including stress-responsive fracture fragment screws, temperature-responsive shape-memory alloy osteogenic healing screws, and secondary compression screws. In addition, by leveraging high-quality clinical and imaging data derived from a randomized controlled trial (RCT), the project seeks to develop and validate an artificial intelligence deep learning-based CT imaging system for intelligent assessment of fracture healing, thereby providing an objective, accurate, and quantifiable method for evaluating bone healing and enabling personalized, precision rehabilitation strategies for patients.
