Chronic pain syndrome after total hip arthroplasty.

Abstract

Introduction. One of the total hip arthroplasty complications is a chronic pain syndrome at different time period. Pain occurs inapproximately 27% ofpatients asdiscomfort and 6% - as persistent pain. Material and methods. We analyzed the results of total hip arthroplasty in140 patients with chronic pain syndrome (85 women and 55 men, mean age 53.4±0.5 years), operated in 2013-2016. As a basic diagnostic causes’s criteria we used hip joint X-ray, methods of ultrasound, magnetic resonance imaging and electroneuromyography. All established pathological processes that trigger the pain were divided into X-ray positiveandX-ray negative. Results. The influence of the following trigger factors ofpain was observed: body weight, age and musculoskeletal system state. Thus, the greatest number of complications and development of pain was seen in patients with excessive body weight or obesity. Spinal column pathology in lumbosacral section led to the reduction in the quality of patient life after total hip arthroplasty. Age up to 50 years and active life style promoted various reactions of bone remodeling in the area of implant pressure. Conclusion. The frequency of complications after surgery leading to chronic pain in our study was consistent with global indexes, and in some cases, was lower.
