Two-dimensional finite element simulation of fracture and fatigue behaviours of alumina microstructures for hip prosthesis [PDF]
Proceedings of the Institution of Mechanical Engineers, Part H:
Journal of Engineering in Medicine 225, 12 (2011) 1158-1168, 2012 This paper describes a two-dimensional (2D) finite element simulation for fracture and fatigue behaviours of pure alumina microstructures such as those found at hip prostheses. Finite element models are developed using actual Al2O3 microstructures and a bilinear cohesive zone law. Simulation conditions are similar to those found at a slip zone in a dry

Hip & Pelvis, 2010 The incidence of the femoral neck fracture is increasing, and the mechanism of the injuries is quite different in the young and elderly groups (high energy injury and osteoporosis, respectively). In the young group, early anatomical reduction and rigid fixation by such measures as multiple cannulated screws are mandatory to decrease the complications ...

Effects of perampanel on bone health in adult patients with epilepsy
Epilepsia Open, EarlyView.Abstract Objective The objective was to assess the effects of perampanel (PER) on bone metabolism and bone mineral density (BMD) in adult patients with epilepsy. Methods This retrospective study included consecutive patients admitted to the Epilepsy Center of Sichuan Provincial People's Hospital from January 2023 to June 2024.

Orthopaedic Surgery, Volume 14, Issue 12, Page 3171-3177, December 2022., 2022 Percutaneous curettage and impaction of allogenic bone graft mixed with autogenic bone marrow aspirate can induce complete resolution of the primary ABCs without use of other adjuvants or any form of internal fixation. Objective Recurrence is the main hinderance in treatment of aneurysmal bone cysts (ABCs).

Orthopaedic Surgery, Volume 14, Issue 12, Page 3178-3186, December 2022., 2022 This study aimed to evaluate the outcomes of cemented stem THA with subtrochanteric femoral shortening and transverse derotational osteotomy in patients with Crowe IV DDH. The cemented femoral component showed promising mid‐term follow‐up results. Rather than leading to nonunion, cement leakage may negatively affect bone healing.

Orthopaedic Surgery, Volume 15, Issue 1, Page 62-69, January 2023., 2023 By exploring the impact of coronal configuration of the proximal femur on its mechanical properties, we provide validation for a new theoretical model and insight of the correlation between lower body force line and hip fracture occurrence. Objective This study aims to establish the coronal configuration of the proximal femur as an independent factor ...
