Background: The purpose of this study was to evaluate the risk peri-prosthetic fracture constructs made with cephalomedullary (CM) long and short nails. nails were titanium alloy (Ti-6Al-4V) stainless steel (SS 316L). Methods: Biomechanical evaluation CM nail carried out regard post-primary healing determine peri-implant/peri-prosthetic fractures. Therefore, research comprised of, non-fractured...
