Comparison of the Dynamic Cut-Out Failure Modes of Common Proximal Femoral Fixation Devices Using a Mesh-Free Computational Method. [PDF]
J Orthop ResMigration and cut‐out of DHS, Gamma3, PFNA‐II, and TFNA were compared under dynamic loading in a stable intertrochanteric fracture benchtop foam model and a mesh‐free simulation. No significant differences in force at cut‐out were observed, but simulation revealed that the volumes of damaged bone foam were 15%, 32%, and 25% higher for the Gamma3, PFNA,

Delayed Peri-Implant Trochanteric Femoral Fractures After Intramedullary Nailing: Surgical Challenges in an Aging Society: A Two-Case Report. [PDF]
Case Rep OrthopIntroduction Fractures, including peri‐implant femoral fractures, are increasing in aging populations. We present two trochanteric femoral fractures post–intramedullary nailing (IMN), highlighting preoperative planning for refracture risks and implant removal. These cases highlight potential surgical challenges in aging societies.
