Radiographic evaluation of sagittal spinopelvic relations in patients with arthrosis deformans of the hip

Purpose. To reveal the details of forming compensatory changes in lumbar lordosis in patients with arthrosis deformans of the hip based on the complex analysis of sagittal radiologic parameters of the lumbar spine and pelvis. Material and Methods. The results of standardized radiologic examination analyzed in 90 patients with uniand bilateral Stage III coxarthrosis combined with chronic lumbalgia. Three pelvic and six spinal sagittal parameters measured, the obtained data processed statistically, correlations established between the studied parameters. Results. The applied clinical-and-radiological study allowed exploring the features of forming compensatory lumbar lordosis in the sagittal plane in patients with coxarthrosis, determining correlations between sagittal pelvic and spinal parameters, as well as identifying the distribution of patients by lumbar lordosis type. Conclusion. The studied details of spinopelvic relations in patients with arthrosis deformans of the hips confirm the presence of significant compensatory changes in the sagittal spine in patients of the category considered, the relations described between the main pelvic and lumbar spinal radiologic parameters.
