Cementless Femoral Neck Endoprosthesis Spiron in Men in Aspects of Clinical Status and Quality of Life in Average a 5-year Follow-up

Abstract Background: Hip arthroplasty is increasingly performed in young people actively playing sports, professionally active, or treated with steroid drugs in the course of autoimmune diseases. Significantly more often in this group of patients the cause of osteoarthritis is sterile femoral head necrosis. Femoral neck endoprosthesis can be an alternative to pituitary or classical cementlessarthroplastyin the surgical treatment of osteoarthritis.Material and methods: The study group consisted of 27 men aged 32 to 65 years (average 46 years) in whom femoral neck endoprosthesis was implanted (16 on the left side, 11 on the right side).The most common indications for surgical treatment were idiopathic osteoarthritis of the hip (19 patients) and arthrosis due to sterile femoral osteonecrosis (8 patients).Operational access according to Hardinge in the patient's position on the back by embedding a uncemented femoral neck endoprosthesis in ceramic articulation was applied.In the studied group of patients, clinical condition was assessed using the HHS, WOMAC-HIP classification. An assessment of the quality of life was also carried out on the SF-12 scale and pain assessment on the VAS scale.Analyzes were performed before surgery, while the control test was carried out on average over a 5-year observation period.Results: The clinical condition of the examined men on the HHS (49.81 vs 84.05) and WOMAC-HIP (40.59 vs 13.5) scale significantly improved (p <0.05) in relation to the value before surgery.Similar results were obtained in the assessment of quality of life on the SF-12 scale (9.89 points vs. 32 points); (p <0.05) and pain on the VAS scale (6.74 vs 0.58); (p <0.05) during follow-up.Conclusions: The use of femoral neck endoprosthesis in men with hip arthrosis in the mean follow-up of 5 years improved both the clinical condition and the quality of life of the operated patients while reducing the pain.
