Synovial fluid from a knee with septic arthritis. In the joint fluid, the typical white blood cell count in septic arthritis is over 50,000–100,000 cells per 10 −6 /l (50,000–100,000 cell/mm 3); [26] where more than 90% are neutrophils is suggestive of septic arthritis. [2]
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]
This is a shortened version of the thirteenth chapter of the ICD-9: Diseases of the Musculoskeletal System and Connective Tissue. It covers ICD codes 710 to 739. The full chapter can be found on pages 395 to 415 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
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 ...
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 ...
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 ...
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. [1]
[17] [18] If septic arthritis needs to be ruled out, needle aspiration of the fluid can be performed under ultrasound guidance. [19] In transient synovitis, the joint fluid will be clear. [5] In septic arthritis, there will be pus in the joint, which can be sent for bacterial culture and antibiotic sensitivity testing.
