Most cases of septic arthritis involve only one organism; however, polymicrobial infections can occur, especially after large open injuries to the joint. [15] Septic arthritis is usually caused by bacteria, but may be caused by viral, [16] mycobacterial, and fungal pathogens as well. It can be broadly classified into three groups: non ...
Other local symptoms are also present, including erythema (redness of the joint), joint swelling, warmth of the joint, and loosening of the prosthetic joint. [2] A sinus tract, or a tract connecting the joint space to the external environment, is more common in chronic PJI, and is definitively diagnostic of PJI. [3]
[3] [4] Septic arthritis is an orthopedic emergency, which, if treatment is delayed, can lead to irreversible joint damage. Septic arthritis occurs more often in childhood than at any other time. [4] [5] Kocher criteria are a useful guide to the diagnosis of septic arthritis in children, especially in the hip, one of the most frequently ...
Protrusio acetabuli is an uncommon defect of the acetabulum, the socket that receives the femoral head to make the hip joint. The hip bone of the pelvic bone/girdle is composed of three bones, the ilium, the ischium and the pubis. In protrusio deformity, there is medial displacement of the femoral head in that the medial aspect of the femoral ...
Most septic arthritis cases caused by anaerobic bacteria are monomicrobial. The predominant anaerobic bacteria isolated are Peptostreptococcus spp. and Propionibacterium acnes (frequently found in prosthetic joint infection), B. fragilis and Fusobacterium spp. (frequently found in infections of hematogenic origin), and Clostridium spp ...
Arthrocentesis can be used to diagnose septic arthritis or crystal arthropathy. [2] In the case of a septic joint, arthrocentesis should preferably be performed prior to starting treatment with antibiotics, in order to ensure a proper sample of synovial fluid is obtained. [3]
Joint replacement is a procedure of orthopedic surgery known also as arthroplasty, in which an arthritic or dysfunctional joint surface is replaced with an orthopedic prosthesis. Joint replacement is considered as a treatment when severe joint pain or dysfunction is not alleviated by less-invasive therapies.
Arthritis caused by bacterial infection of the joint is termed septic arthritis and does not commonly affect multiple joints. It may notably be caused by gonococcus . Bacteria can also cause polyarthritis not by directly infecting the joints; instead, infection located elsewhere in the body can cause immune reaction , which becomes the direct ...
