Abstract:
BackhroundsIt has remained controversial whether total hip arthroplasty (THA) can affect thesagittal spinopelvic alignment. In current study, the changes in sagittal spinopelvicparameters was investigated in patients with end-stage hip osteoarthrtitis and lowback pain (LBP) following THA.MethodsThere were 27 patients underwent THA enrolled in current study. Before and afterthe operation, lateral standing spinopelvic x-rays (from cervical spine to pelvis) weretaken. The measured variables included: pelvic incidence (PI), sacral slope (SS), pelvictilt (PT), lumbar lordosis (LL), lumbar scoliosis, sagittal balance and range of hipsagittal motion. In addition, Ostwestry disability index (ODI) was completed before and after surgery. Patients were followed at least for 6 months.ResultsNone of the radiographic spinopelvic parameters changed significantly after theoperation. Range of motion increased significantly (12.7±84.6 degrees Vs 16.3±118.1degrees, p<0.001). Furthermore, ODI did not changed significantly after the operation(6.6±27.5 Vs 4.7±24.3, p=0.382).ConclusionsTHA did not affect the sagittal spinopelvic parameters measured in standing staticx-rays. Since ODI was the same before and after the operation, the authors suggestto address LBP before THA in patients in whom LBP comorbid the hip osteoarthritis.
