Item Metadata only Comparative biomechanical performance of two configurations of screw constructs and types used to stabilize different sites of unstable Pauwels type II femoral neck fractures: A finite element analysis(2022-09-01) Chantarapanich N.; Jitprapaikulsarn S.; Mahaisavariya B.; Mahaisavariya C.; Mahidol Universityin stabilizing Pauwels type II femoral neck fracture sub-capital, mid-cervical, and basilar regions using Finite Element (FE) method. Methods: A 3D femur model was created for Pauwels type II femoral neck fractures. The fracture sites were in the mid-cervicalItem Metadata only Torsional Stability of the Femoral Neck System for Pauwels Type III Femoral Neck Fracture Fixation: A Finite-element Analysis(2026-05-01) Chantarapanich N.; Jitprapaikulsarn S.; Mahaisavariya B.; Mahaisavariya C.; Chantarapanich N.; Mahidol Universityload sharing than multiple screw fixation; however, it has a lower load-to-failure than plate systems. We evaluated the torsional stability of the FNS using finite-element analysis. METHODS: We analyzed a transcervical Pauwels type III femoral neck... fracture without a fracture gap, fixed with one of three constructs: multiple screw fixation, a dynamic hip screw (DHS) with an antirotation screw, or an FNS. Finite-element simulations incorporated muscle forces during the leg-swing phase, with constraintsItem Metadata only Dual plating for fixation failure of the distal femur: Finite element analysis and a clinical series(2023-01-01) Jitprapaikulsarn S.; Chantarapanich N.; Gromprasit A.; Mahaisavariya C.; Sukha K.; Chiawchan S.; Mahidol Universityelement (FE) analysis and retrospectively described the clinical outcomes of the present technique in such difficult circumstances. Methods:: Biomechanical study setting included FE models of the distal femur with remaining holes from previous distal femur...Background:: The optimal technique for managing distal femur fixation failure remains inconclusive. The author studied the efficacy of a combined proximal humerus locking compression plate (LCP-PH) and 3.5 mm reconstruction plate (LCP-RP) by finiteItem Metadata only Roles of a nonvascularized fibular graft with and without fixation in the treatment of segmental tibial bone loss: A finite element analysis(2025-11-01) Jitprapaikulsarn S.; Chantarapanich N.; Apivatthakakul T.; Ruchawapol C.; Gromprasit A.; Sengpanich P.; Mahaisavariya C.; Sukhan R.; Jitprapaikulsarn S.; Mahidol Universityof the present study were to mechanically test the influences of various NVFG fixation techniques on the overall stability of the fixation construct by use of finite element analysis.
