文题释义:
股骨头坏死塌陷:一旦股骨头发生塌陷将导致负重区软骨不可逆损害,骨性关节炎不可避免,最终不得不行人工髋关节置换。塌陷是股骨头坏死的分水岭,所以理解塌陷的机制至关重要。股骨头坏死塌陷率为44%-79%,约50%患者从诊断至塌陷时间低于2年。股骨头坏死自然病史表明,并非所有的坏死股骨头都会塌陷。对塌陷风险较小的病例,可采取非手术治疗和临床随访,避免过度治疗;对塌陷风险较高的病例,在塌陷前期及时采取有效的保髋治疗,疗效明显较优。
保存自身髋关节:简称保髋,是相对于人工关节置换而言的概念。保髋是公认的治疗目标,并且诸多学者提出过诸多的实践方法,但保髋治疗有较高的失败率,主要的原因是目前临床中缺乏塌陷机制的认识,缺乏有效预测塌陷风险和防治塌陷的方法。
股骨头坏死“三部失效”塌陷机制假说:坏死区骨小梁的疲劳骨折、软骨下皮质骨壳的皱褶剥离和修复反应带的吸收沉降。基于“三部失效”塌陷机制学说的保髋新术式不但能够重建股骨头前外侧柱的形态,还能够重建有效的载荷传递通道并具有全程生物力学稳定性。
摘要
背景:
股骨头坏死的临床保髋疗效仍不尽如人意。
目的:分析股骨头坏死塌陷的机制,指出其改进的方向。
方法:根据作者所在团队近5年的系列研究,率先提出了股骨头坏死“三部失效”塌陷机制假说,并从生物力学、病理学和临床应用3方面进行验证。
结果与结论:提出了维稳修复的保存自身髋关节新理念和旨在重建股骨头前外侧柱的保髋新术式,短期疗效优良,显示其中远期临床疗效和作用机制值得期待和深入研究。

Abstract:

BACKGROUND: Unsatisfactory clinical efficacy of hip-preserving treatment after osteonecrosis of the femoral head is unavoidable.
OBJECTIVE: To reveal the collapse mechanism of osteonecrosis of the femoral head, and then point out the direction for improvement.
METHODS: We put up with three-part failure collapse mechanism hypothesis of osteonecrosis of the femoral head for the first time according to a series of studies by our research team in recent 5 years, paralleling with preliminary verification from three aspects of biomechanics, pathology and clinical application.
RESULTS AND CONCLUSION: New concept of maintaining stability and promoting repair for hip preservation and new surgical procedures aiming at the reconstruction of femoral head anterior lateral columns are well presented, and good short-term effects have been achieved. These results show that the mid-long-term clinical curative effect and mechanism of action are worthy of further study.
