Особенности предоперационного планирования эндопротезирования тазобедренного сустава

Abstract

Relevance. Preoperative planning is an integral stage of hip replacement surgery, which reduces the number of complications and improves the accuracy of the installation of endoprosthesis components. Goal. Assess the accuracy of digital preoperative planning using mediCAD® v.6. Material and methods. The study included data from 276 patients with idiopathic coxarthrosis who were treated at the orthopedic department of the Center of Traumatology and Orthopedics of the Main Military Clinical Hospital named after N.N. Burdenko in the period from 2018 to 2020.The patients had X-rays of the pelvis and hip joint in two projections. All patients underwent total hip arthroplasty with cementless endoprostheses. Before surgery, all patients underwent preoperative planning using the mediCAD® v.6 software. After the operation, a control X-ray was performed, followed by an assessment of the obtained images in the same software. The planning accuracy was evaluated by comparing the parameters that were calculated in the program before the operation with the parameters of the installed implants. The results. The conducted study demonstrated the high accuracy of digital preoperative planning. The coincidence of the planned sizes of the acetabular component of the endoprosthesis and a deviation within +/- one size was observed in 93% of patients, femoral — in 84% of patients. Conclusion. Preoperative planning is an integral stage of hip replacement surgery, which allows you to perform the necessary preparation for the intervention. Digital planning allows you to simplify and speed up the process of preparing for an operation and improve the quality of its execution.
