Assessment of the effectiveness of the replacement of hip joints in patients with spondyloarthritis

The lesion of the hip joint with ankylosing spondylitis (AS) is an unfavorable prognostic sign and can lead to the endoprosthetics (EP) of the joint. Objective. to evaluate the results of the EP of the hip joints in patients with AS with joint dynamic observation by a rheumatologist and orthopedist during the first year after surgery. Materials and methods. The results of the EP of the hip joint of 120 patients in three groups of one central study were analyzed. The 1st and 2nd groups consisted of patients with ankylosing spondylarthrosis after endoprosthetics of the hip joint, but with various options for maintenance in terms of basic therapy, and the 3rd group with coxsartrosis after planned replacement of the joint. Dynamic observation by the rheumatologist and orthopedist was carried out before the operation, after the operation, after 6 and 12 months. Results. The effectiveness of arthroplasty of large joints with a reliable (p <0.05) decrease in pain (VAS) in the first month after EP, improving functional capacity (BASFI) and a decrease in ASDAS (ASDAS) after 6 and 12 months after EP. There were no complications after the operation. A clinical example of a patient with a severe course of ankylosing spondylitis and the effectiveness of arthroplasty is presented. Conclusion. EP of the hip joints in patients with spondiloarthritis is effective not only in terms of improving the functional ability and removing pain, but also to reduce the activity of the disease as a whole
