[Extracorporeal shockwave therapy for osteonecrosis of femoral head: traps and challenges].

Extracorporeal shock wave (ESW), as a noninvasive, safe, and effective treatment, was applied to the treatment in osteonecrosis of femoral head (ONFH) since the end of last century. Although this therapy is more and more widely used, there are many traps and challenges. We recommend using the high-energy focus ESW to treat ONFH, rather than using the low energy radial pressure wave. Furthermore, for different types ONFH, scientific personalized treatment planning should be made first. There are demands of multicenter united researches for this unknown field of ONFH treated with ESW, and so to provide high-level evidence-based medicine evidence. 体外震波（extracorporeal shock wave，ESW）又称体外冲击波，作为一种非侵入性、安全有效的非手术治疗手段，从上世纪末开始应用到股骨头坏死（osteonecrosis of femoral head，ONFH）治疗中。在此技术被越来越广泛应用的同时，仍存在很多误区和挑战。建议使用聚焦式、高能量 ESW 治疗 ONFH，而非低能量发散式压力波；对不同类型的 ONFH 制定个体化科学的治疗方案；建议对 ESW 治疗 ONFH 进行多中心联合研究，共同探索其未知领域，并提供高水平的临床循证医学研究证据。.
