摘　　要：股骨转子间骨折是老年人常见的骨折类型之一,随着医疗水平及生活水平的普遍提高,高龄人群越来越多,同时骨质疏松问题也变得相对突出,因此通常低暴力即可造成老年人股骨转子间骨折,给老年患者生活质量造成了极大的消极影响。随着医疗水平及内固定材料的进一步发展,股骨近端防旋髓内钉(PFNA)的出现极大改善了老年患者股骨转子间骨折的治疗效果,但随着治疗患者量的不断增多,内固定失败也被不断报道。近年来股骨近端仿生髓内钉(PFBN)被报道具有良好的临床疗效。本文将主要阐述PFBN的设计理论依据、特点、生物力学及临床疗效研究,为今后老年患者股骨转子间骨折的临床治疗提供更多的参考。Femoral intertrochanteric fracture is one of the common types of fractures in the elderly.With the general improvement of medical and living standards,the number of elderly people is increasing,and the problem of osteoporosis has also become relatively prominent.Therefore,low violence can usually cause fractures in this area of the elderly,which has a significant negative impact on the quality of life of elderly patients.With the further development of medical technology and internal fixation materials,the emergence of proximal femoral nail antirotation(PFNA)has greatly improved the treatment effect of femoral intertrochanteric fractures in elderly patients.However,with the increasing number of patients treated,internal fixation failures have gradually been reported.In recent years,proximal femoral biomimetic intramedullary nail(PFBN)has been reported to have good clinical efficacy.Therefore,this article mainly elaborates on the theoretical basis,design characteristics,biomechanics,and clinical efficacy research of PFBN,providing more reference for the clinical treatment of femoral intertrochanteric fractures in elderly patients in the future.
