This study presented to compare the stiffness, fatigue testing, and compressive strength between stable (AO31-A2.1) and unstable (AO31-A3.3) intertrochanteric fractures treated by cement augmented PFNA of the cadaveric femoral. Biphasic calcium phosphate cement was injected to align and compatible with PFNA and the reconstructive procedure was monitored the cement placement using x-ray imaging during operation. The testing demonstrated that the cement could be injected through a small needle (13 G, 16 cm length, 1.8 mm inner diameter) within a suitable operating time. The feasibility study of the biomechanical testing was divided into three tests: stiffness test, fatigue cyclic load, and compression test. The results showed that the cement-augmented specimens exhibited higher stiffness than the control specimens without cement. The cement-augmented specimens also showed lower strain energy during the fatigue test, resulting in higher compressive strength (4730.7 N) compared to the control specimens (3857.4 N). There is a correlation between BMD and fracture load and the increase in compression load of the cement-augmented femoral compared to the controls as well as an increase in strain energy of fatigue cyclic testing was found. Biphasic calcium phosphate cement-augmented of the PFNA biomechanically enhanced the cut-out resistance in intertrochanteric fracture. This procedure is especially efficient for unstable intertrochanteric fracture suggesting the potential benefits of using biphasic calcium phosphate cement in medical applications.<\/jats:p>","DOI":"10.1088\/2057-1976\/ad4e3c","type":"journal-article","created":{"date-parts":[[2024,5,21]],"date-time":"2024-05-21T22:20:41Z","timestamp":1716330041000},"page":"045043","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Feasibility biomechanical study of injectable Biphasic Calcium Phosphate bone cement augmentation of the proximal femoral nail antirotation (PFNA) for the treatment of two intertrochanteric fractures using cadaveric femur"],"prefix":"10.1088","volume":"10","author":[{"given":"Ponthep","family":"Tangkanjanavelukul","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paritat","family":"Thaitalay","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sawitri","family":"Srisuwan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pongpayap","family":"Petchwisai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pornsak","family":"Thasanaraphan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yotakarn","family":"Saramas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kittiphong","family":"Nimarkorn","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Woranat","family":"Warojananulak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7643-8469","authenticated-orcid":true,"given":"Chaosuan","family":"Kanchanomai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5241-7893","authenticated-orcid":true,"given":"Sirirat Tubsungnoen","family":"Rattanachan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","published-online":{"date-parts":[[2024,6,13]]},"reference":[{"key":"bpexad4e3cbib1","doi-asserted-by":"publisher","first-page":"95","DOI":"10.1016\/j.otsr.2019.04.027","article-title":"Comparative finite element analysis of three implants fixing stable and unstable subtrochanteric femoral fractures: proximal femoral nail antirotation (PFNA), proximal femoral locking plate (PFLP), and reverse less invasive stabilization system (LISS)","volume":"106","author":"Wang","year":"2020","journal-title":"Orthop Traumatol Surg Res."},{"key":"bpexad4e3cbib2","first-page":"6","article-title":"Efficacy of femoral nail anti-rotation of helical blade in unstable intertrochanteric fracture","volume":"21","author":"Guo","year":"2017","journal-title":"Eur.
