Total Hip Arthroplasty in Patients With Post-Traumatic Bone Defects and Acetabular Deformities

Backround. Total hip replacement in cases of traumatic changes the acetabulum refers to difficult primary arthroplasty and requires detailed preoperative planning accurate restoration anatomical relationships operated joint.
 The aim study was evaluate structure pathological patients with posttraumatic arthrosis, develop a method for their description determine tactics choosing type implant.
 Methods. results treatment 194 consequences fractures who underwent total period from 2014 2022 were analyzed. conducted two stages, at first stage, changes, such as defect, deformation, center rotation offset (relatively healthy contralateral joint), A developed implantation component, based on defect deformation acetabulum. second stage analyzed whom surgical carried out 2020 using proposed method.
 Results. During study, it revealed that magnitude change indicators displacement by more than 8 mm. statistically significantly increases likelihood complications 17.9%. reduces number 22.3%. makes possible reliably restore joint reduce 10%.
 Conclusion. allows us qualitatively quantitatively describe bone tissue Depending degree rotation, walls nature supporting tissue, surgeon can treatment.
