PURULENT-NECROTIC COMPLICATIONS AFTER SURGICAL INTERVENTIONS IN THE HIP JOINT

Purulent necrotic complications after surgical interventions on the hip joint remain one of the most severe problems in orthopedic practice due to their rapid progression, diagnostic complexity, and high risk of unfavorable functional outcomes. This study analyzes clinical, laboratory, and radiological features of purulent necrotic processes developing in the early and late postoperative periods after hip joint surgery. Special attention is given to the importance of early diagnosis based on a comprehensive assessment that includes clinical symptoms, biochemical and bacteriological indicators, immunological data, and modern imaging techniques. In the early postoperative stage, purulent complications are characterized by fever, general intoxication, pain, soft tissue swelling, and limited joint mobility, while radiological signs may be absent. Delayed diagnosis often leads to deep soft tissue suppuration, diffuse osteoporosis, narrowing of the joint space, femoral head damage, instability of the joint, and complications related to implanted metal structures. The study also considers pathogenetic mechanisms of dystrophic changes in the femoral head associated with hip dysplasia, emphasizing the role of impaired blood supply, mechanical instability, and prolonged non physiological positioning of the joint. Diagnostic differentiation between hip arthritis, osteomyelitis of the proximal femur, and soft tissue infections is highlighted as a key factor in choosing appropriate treatment tactics. The results confirm that timely detection and adequate surgical management significantly improve functional outcomes and reduce the risk of severe destructive changes. Along with radiography, contrast studies, and histological analysis, radionuclide and infrared diagnostic methods are proposed as valuable tools for early identification of acute purulent processes in the hip joint.
