Surface deformation relief (SDR) of the contact areas of a hip joint endoprosthesis subjected to wear was studied at different structural levels using laser scanning microscopy. Quantitative ...comparative 3D analysis of the SDR parameters characterizing postimplantation changes in components of the implant was performed. It was found that wear of the kinematic unit was eccentric and heterogeneous. Deep local surface changes were mainly observed at the upper pole of the head and the insert. The bottom segments of the insert remained intact even after long-term use of the tribological pair. The SDR of these segments remained intact.
The hip arthroplasty in case of destructive - dystrophic affection is considered as the most effective method, which provided social and home reintegration. A modern science development facilitates ...to this technique. However, specialists noted that the rate of endoprosthesis complication increased in the patients after osteosynthesis of proximal femur. The authors compared the results of patient’s treatment that applied hip arthroplasty methods after osteosynthesis of proximal femur. The main group consisted of 38 patients who underwent hip arthroplasty after osteosynthesis of proximal femur. The control group had 43 patients with hip idiopathic osteoarthrosis, who underwent primary arthroplasty. The endoprothesis replacement was associated with increase of the rate of intraoperative and postoperative complications in the main group of patients. According to the results, given group of patients requires a special approach to diagnostics and treatment.
Surgical treatment of destructive and degenerative diseases of the hip arthroplasty technology with the modern development of science, technology and medicine is considered the most effective method ...of providing social and personal reintegration. However, the opinion of experts, arthroplasty increases the complication rate in patients after osteosynthesis and osteotomy of the proximal femur. The purpose of research - to compare patient outcomes Technology hip arthroplasty after-reducing reconstructive interventions at the proximal femur. Material and Methods: The study group comprised 42 patients who underwent hip arthroplasty after-reducing reconstructive interventions at the proximal femur. The control group consisted of 43 patients with idiopathic hip osteoarthritis who underwent primary arthroplasty. Results: conducting joint replacement in patients of the main group was accompanied by an increase in the frequency of intraoperative and postoperative complications. Therefore, this group of patients requires a special approach to diagnosis and treatment.
