Analysis of intertrochanteric femoral fracture with damaged lateral wall osteosynthesis

Objective: Investigate the peculiarities of osteosynthesis with intramedulary nails and locking plates of femur fractures with damaged lateral wall using 3D virtual surgery planning method. Tasks: Compare osteosynthesis with different design intramedullary nails and locking plate of patients that have 31-A3 (AO/OTA) fracture with type II and III (Cho JW et al., 2017) femoral lateral wall destruction. Methodology: Using 3D virtual surgery planning method proximal part of femur, intramdullary nails with different design A with one support screw that is 11mm diameter and B with two smaller 5.3 mm diameter support screws, locking plate PF-LCP were formed and virtual osteosynthesis was carried out. Randomly 35 patients of LUHS were chosen that had pelvis CT scan done in the past in LUHS. Results: Using PF – LCP with one support screw for 31-A3 (AO/OTA) Type II fracture osteosynthesis resulted in 57% successful fixation. Using 3 screws with the same PF – LCP in type III fracture resulted in 97% successful fixation. There was a greater successfull implantation of both design nails in women group compared to male group (p
