Topic:Septic Arthritis
Septic arthritis in horses is a condition characterized by the inflammation of a joint due to bacterial infection. It typically involves the synovial membrane and joint capsule, leading to pain, swelling, and lameness. The condition can result from direct penetration of the joint by bacteria, such as through a wound, or via hematogenous spread from a systemic infection. Diagnosis often involves clinical examination, synovial fluid analysis, and imaging techniques. Treatment generally includes antimicrobial therapy and joint lavage to remove infectious agents and inflammatory debris. This page aggregates peer-reviewed research studies and scholarly articles that explore the pathophysiology, diagnostic methods, and treatment options for septic arthritis in equine patients.
A retrospective study of 192 horses affected with septic arthritis/tenosynovitis. The medical records of 192 horses with septic arthritis/tenosynovitis 1979-1989 were reviewed. Forty-three horses developed infection after an intra-articular injection, 46 following a penetrating wound, 25 following surgery, 66 were foals less than 6 months old, and 12 were adult horses without a known aetiology. Haematogenous infection of a joint occurs in adult horses and should be considered as a differential diagnosis in horses with an acute onset of severe lameness. The aetiology of the infection had a significant effect on the type of bacteria identified by culture. Staphylococcus was c...
Septic arthritis of the distal interphalangeal joint in 12 horses. The medical records of 12 horses with septic arthritis of a distal interphalangeal joint were reviewed to determine clinical features and response to treatment. Sepsis was caused by trauma or an injection that resulted in an open or contaminated distal interphalangeal joint. All horses were severely lame. Treatment included broad-spectrum parenterally administered antimicrobial drugs (ten horses), percutaneous through-and-through joint lavage (eight horses), indwelling drains (three horses), immobilization of the limb in a cast (three horses), intraarticular injection of sodium hyaluronate (on...
Evaluation of sodium hyaluronate therapy in induced septic arthritis in the horse. This study was conducted to determine the efficacy of sodium hyaluronate (SH) with antibiotic therapy and joint lavage for reducing acute inflammatory and degenerative changes induced by septic arthritis. Septic arthritis was induced in six adult horses by inoculating the tarsocrural joints with 1 x 10(4) colony-forming units of Staphylococcus aureus. When clinical signs appeared, trimethoprim-sulphamethoxazole (30 mg/kg bodyweight [bwt] daily) and phenylbutazone (4.4 mg/kg bwt sid) were administered and continued until termination of the study (Treatment Day 18). Twenty-four hours post inocul...
Review of pathogenesis and treatment of degenerative joint disease. Treatment of degenerative joint disease (osteoarthritis) is discussed in relationship to pathogenesis of five clinical entities, defined to facilitate discussion:-1) occurring in high motion joints and associated with synovitis; 2) associated with low motion joints; 3) "non-progressive" articular cartilage erosion; 4) secondary to other identified problems (intra-articular fractures, ligamentous damage, wounds, septic arthritis, osteochondrosis); and 5) chondromalacia of the patella. In addition to direct damage to articular cartilage, synovitis and capsulitis and depletion of matrical glycosa...
Shoulder lameness in horses: an analysis of 58 suspected cases. The results of a detailed investigation of 58 horses with suspected shoulder lameness are described. Lameness was found to originate distal to the shoulder region in 22 horses. No diagnosis was reached in five horses. Genuine shoulder problems occurred in 29 horses. The clinical signs of shoulder lameness are described and contrasted with lower limb lameness. The limitations of currently available diagnostic techniques are discussed. Problems identified in the shoulder region included osteochondritis dissecans, subchondral bone cysts, arthrosis, fracture, luxation, septic arthritis and soft ti...
The diagnosis and treatment of arthritis in horses. In this paper on the diagnosis and treatment of arthritis in horses, both degenerative arthritis and septic arthritis are considered. Diagnosis should be made on the combination of clinical examination together with the use of diagnostic aids such as radiology, intra-articular local anaesthesia and synovial fluid analysis. Intra-articular therapy appears to be the most effective in the treatment of degenerative arthritis. Excellent responses to therapy have been reported with corticosteroids, sodium hyaluronate, orgotein and synovial fluid transfer, where joints showed an absence of degenerati...
