Hi dr zakia dimassi c est un arthrite septique
Aug 17, 2014
2nd opinion

Dr. Zakia Dimassi Pediatrics
Allow me to answer your question in English :)
Septic arthritis in neonates can occur as a sequel to neonatal sepsis. The most common germs causing it are staphylococcus aureus, and streptococcus (Group B streptococcus). The infection gets to the joint through the blood stream. Neonates usually only have subtle symptoms: they may not have fever, and the only noticeable sign is that they stop moving the affected joint.
The mainstay of treatment is antibiotics that targets the specific bacteria (this is determined by aspiration of the joint if feasible), and irrigation of the affected joint. Post operative physiotherapy is important to allow proper movement, and splinting is necessary to prevent contractures.
Of note that in neonates, the majority of cases of septic arthritis have coexisting osteoarthritis, because the joints and bones are not mature enough so the infection is not limited to the joint.
Possible long term sequel is joint deformity.
The joint needs to be thoroughly irrigated (washed) and appropriate antibiotic therapy started. Deep joints such as the hip are difficult to aspirate.
An open arthropods, whereby the joint is cut open, is recommended in most cases. Arthroscopic (accessing the joint with a scope) is also effective method of thoroughly rinsing out a joint.
After incision (making a cut) and exposing the joint, samples of pus swabs and fluid for culture. The joint is irrigated syringe and all pus is washed out.
After surgery, antibiotics are given in the blood (intravenously) until the temperature goes back to normal, followed by oral antibiotics.
Physiotherapy will be required in most cases rather than immobilisation.
Contractures are prevented by the application of splints.
