Factor analysis of biochemical and clinical indicators of aseptic necrosis of the femoral head

Introduction The study of pathogenesis and improving the diagnosis of aseptic necrosis of the femoral head (ANFH) is one of the challenging problems of regenerative orthopedics. ANFH is a polyetiologic disease characterized by a local increase in the resorption activity of osteoclasts along with inhibition of activity of mesenchymal cells and osteoblasts, which lead to a significant loss of bone tissue. In this connection, it seems to us relevant to study biochemical and clinical markers of bone resorption and remodeling as diagnostic criteria for ANFH. The purpose of the study was to identify the relationship of some biochemical markers of bone tissue metabolism that reflect the balance between resorption and remodeling with clinical ones (gender, age, T- and Z-criteria), evaluate specifically the deficit of vitamin D in patients with ANFH. Materials and methods Clinical and biochemical study included 195 people with a verified diagnosis of aseptic necrosis of the femoral head who had not previously received vitamin D preparations...
