A Novel Internal Fixation Design for the Treatment of AO/OTA‐31A3.3 Intertrochanteric Fractures: Finite Element Analysis

Orthopaedic Surgery, Volume 16, Issue 7, Page 1684-1694, July 2024.
Guided by “lever‐reconstruction‐balance” hypothesis, we have engineered proximal femoral totally bionic screw (PFTBN) aimed at reconstructing the mechanical role and functionality of the lateral wall. Using the finite element analysis method, PFTBN outperforms proximal femoral nail antirotation (PFNA) and proximal femoral bionic nail (PFBN) concerning ...

Torsional stability of fixation methods in basicervical femoral neck fractures: a biomechanical study

Journal of Orthopaedic Surgery and Research
Background Basicervical femoral neck fracture is a rare proximal femur fracture with a high implant failure rate. Biomechanical comparisons between cephalomedullary nails (CMNs) and dynamic hip screws (DHSs) under torsion loading are lacking.

Indications for implant removal after fracture healing: a review of the literature [PDF]

, 2013
Introduction: The aim of this review was to collect and summarize published data on the indications for implant removal after fracture healing, since these are not well defined and guidelines hardly exist.

Finite Element Analysis of Six Internal Fixations in the Treatment of Pauwels Type III Femoral Neck Fracture

Orthopaedic Surgery, Volume 16, Issue 7, Page 1695-1709, July 2024.
In this study, the three CCS + MBP showed the best biomechanical stability compared with the other five internal fixation models. The biomechanical stability of DHS + DS was second only to that of the three CCS + MBP, and both could be considered as a treatment for Pauwels III femoral neck fracture based on biomechanical stability alone. However, after

Comparison between proximal femoral nail and dynamic hip screw in non-displaced or minimally displaced intertrochanteric fractures of the femur: a prospective study

Travmatologiâ i Ortopediâ Rossii
Background. Proximal femoral nail (PFN) and dynamic hip screw (DHS) are widely used for the management of intertrochanteric femur fractures (ITFs). Proximal femoral nailing offers biomechanical advantages but may cause iatrogenic displacement during the ...
