Abstract

Every year in the world they perform about 1 million of total hip replacements (THR). In 6–10 % of patients with pathology of this joint they observe significant violations of configuration of the articular surface in the form of deformities and defects. Destructive changes in the hip joint (HJ) are also associated with proximal femoral corrective osteotomies (PFCO) and require THR. During reconstructive surgery it is necessary to restore normal anatomic relationships between the bone structures that form the HJ. This is due to physiological biomechanics of movement in the HJ which is possible just upon condition of restoration of its anatomical shape. In this paper we assessed the impact of PFCO in adults to possible further implantation of the endoprosthesis taking into account some technical features of surgery. It was established that PFCO in adults cause significant changes in the anatomical shape of the proximal femur manifesting with polygonal deformations of metaepiphysis and medullary canal. Pathological restructuring of bone structures associated with overgrowth medullary canal at the level of osteotomy and the formation of zones of local osteoporosis or cavities in the proximal metaepiphysis. These factors contribute to adverse outcomes for individual THR which is displayed in a large number of early postoperative complications due to the instability of the endoprosthesis' components. However one should note that in the last decade possibilities of diagnostic equipment significantly increased which creates prerequisites for early diagnosis of degenerative joint diseases at a new level. In this regard renaissance of reconstructive surgeries on the HJ is quite possible.
