Biomechanical aspects of spine sagittal balance in patients with coxarthrosis in total hip replacement (preliminary study)

The purpose of the study was to evaluate specific features of spine sagittal balance in patients with coxarthrosis of different etiology before and after total hip replacement (THR). Materials and methods Clinical and radiographic evaluation was performed for 46 patients admitted for primary THR. The patients were diagnosed with dysplastic (n = 14), degenerative (n = 26) and posttraumatic (n = 6) coxarthrosis and evaluated preoperatively, on the 7th day postsurgery and at a long-term follow-up. Spinopelvic parameters of sagittal balance, stages of osteoarthritis and cranial displacement of femoral heads according to Crowe were assessed. Clinical evaluation included physical examination, hip function with the Harris Hip Score (HHS), range of motion in the involved hip, relative limb shortening, neurological status, Oswestry questionnaire (ODI) and spinal pain syndrome using the Wong-Baker Faces Pain Rating Scale (2011). A statistical software package of Microsoft Office Excel 2016 was applied for data analysis...
