DYNAMICS OF CHANGES IN SAGITTAL SPINAL-PELVIC ALIGNMENT DURING STAGED SURGICAL TREATMENT OF PATIENTS WITH CONCOMITANT DEGENERATIVE-DYSTROPHIC LESIONS TO THE HIP AND SPINE

The paper presents results of staged surgical treatment of patients with concomitant degenerative-dystrophic diseases of the hip and spine. The analysis of clinical observation suggests the possibility of decompensation of degenerative-dystrophic disease of the lumbosacral spine accompanied by spinal canal stenosis and instability of spinal motion segments after total hip arthroplasty. Decompression surgery eliminating spinal canal stenosis allows to restore lumbar lordosis and manage the pain syndrome. Surgical decompression combined with correction and fixation of the lower lumbar motion segments allows to normalize sagittal spinal-pelvic relationship by restoring both lumbar lordosis and anatomic pelvic anteversion.
