Proximal femoral nail anti\u2010rotation (PFNA) and InterTan are the preferred internal fixation devices for intertrochanteric femur fractures in elderly individuals due to their advantages, such as a short lever arm, minimal stress shielding, and resistance to rotation. However, PFNA is associated with complications such as nail back\u2010out and helical blade cut\u2010out due to stress concentration. As a new internal fixation device for intertrochanteric femur fractures, the proximal femoral biodegradable nail (PFBN) addresses the issue of nail back\u2010out and offers more stable fracture fixation, a shorter lever arm, and stress distribution compared to PFNA and InterTan. Clinical studies have shown that compared to PFNA, PFBNs lead to faster recovery of hip joint function, shorter non\u2010weight\u2010bearing time, and faster fracture healing. This article provides a literature review of the structural characteristics, biomechanical analysis, and clinical studies of PFBNs, aiming to provide a theoretical basis for the selection of internal fixation devices for the treatment of intertrochanteric femur fractures in elderly patients and to improve the quality of life of patients during the postoperative period.<\/jats:p>","DOI":"10.1111\/os.14134","type":"journal-article","created":{"date-parts":[[2024,7,10]],"date-time":"2024-07-10T03:50:42Z","timestamp":1720583442000},"page":"2303-2310","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Research Progress on the Treatment of Geriatric Intertrochanteric Femur Fractures with Proximal Femur Bionic Nails (<scp>PFBNs<\/scp>)"],"prefix":"10.1111","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-3461-1201","authenticated-orcid":false,"given":"Wenyu","family":"Duan","sequence":"first","affiliation":[{"name":"Baotou Medical College  Baotou China"},{"name":"Department of Traumatic Surgery, The First Affiliated Hospital of Baotou Medical College  Baotou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-3166-3032","authenticated-orcid":false,"given":"Hao","family":"Liang","sequence":"additional","affiliation":[{"name":"Baotou Medical College  Baotou China"},{"name":"Department of Traumatic Surgery, The First Affiliated Hospital of Baotou Medical College  Baotou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaolong","family":"Fan","sequence":"additional","affiliation":[{"name":"Department of Traumatic Surgery, The First Affiliated Hospital of Baotou Medical College  Baotou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongming","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Traumatic Surgery, The First Affiliated Hospital of Baotou Medical College  Baotou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yulu","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Traumatic Surgery, The First Affiliated Hospital of Baotou Medical College  Baotou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haidong","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Traumatic Surgery, The First Affiliated Hospital of Baotou Medical College  Baotou China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,7,9]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ocl.2019.11.011"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11657-022-01082-0"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1186\/s13018-021-02874-9"},{"issue":"2","key":"e_1_2_10_5_1","first-page":"93","article-title":"Clinical practice guidelines for elderly intertrochanteric fractures","volume":"22","author":"Chinese Fragility Fracture Alliance","year":"2020","journal-title":"Chin J Traumatol Orthop"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12889-023-16776-4"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.105B11.BJJ-2023-0139.R1"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00402-022-04676-y"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.medengphy.2021.10.001"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.heliyon.2024.e29671"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.3389\/fbioe.2023.1297507"},{"issue":"5","key":"e_1_2_10_12_1","first-page":"257","article-title":"Design philosophy of the N\u2010triangular theory of the proximal femur and the proximal femoral biomimetic intramedullary nail (PFBN)","volume":"07","author":"Zhu YB","year":"2021","journal-title":"Chin J Geriatric Orthop Rehabil"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10654-010-9491-z"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.4103\/jpgm.JPGM_104_21"},{"key":"e_1_2_10_15_1","unstructured":"ZhangDY WangYH ZhangXM MaF ZhangYY QiP et al.Inventors: femoral intramedullary nail fixation system.
