ABSTRACT
Background: Accidents are the major reasons causing hip bone fractures. These are due to reduced bone density due to aging effect which may cause fractures typically in proximal part of the femur bone. Objectives: The purpose of this work is to concentrate on preoperative planning by using a 3D model developed with a virtual operation using a dynamic hip screw (DHS). Materials and Methods: DHS is generally preferred for the stabilization of stable fractures. The virtual operation was performed on the proximal femoral fracture site, typically for stable fractures. Finite element analysis (FEA) of operated bone was performed to estimate Von Misses stress distribution on the implant post-operatively, resulting in less stress on the fracture site. Results: FEA indicates a transfer of stress of the fracture site (35–62%) on the implant, resulting in the operation’s success. Such work will assist orthopedic surgeons in determining load-bearing capacities after the mobilization of the patient. Conclusion: Virtual surgery helps the surgeon to identify fracture geometry, the success of the operation, and proper fixation of the implant to avoid post-surgery complications. This aids in the quick recovery of patients, resulting in early rehabilitation.
