Detect short term results of pediatric septic hip arthritis and its risk factors

Septic arthritis of the hip is a true orthopedic emergency(1). In developed countries, the incidence of acute bacterial septic arthritis is estimated to be 4 to 10 per 100,000 children (2).It is caused by many microorganisms. Staph aureus is most common in children over 2 years of age . Staph aureus is gram-positive cocci in clusters and most common in nosocomial infections of neonates(3-4).Group B streptococcus is most common in neonates with community-acquired infection and exposed during transvaginal delivery(5).Neisseria gonorrhoeae is gram-negative diplococci and most common in adolescents.when the causative Organism is Neisseria gonorrhoeae ,patients usually have a preceding migratory polyarthralgia,multiple joint involvement and small red papules(6-7).Group A beta-hemolytic streptococcus is most common organism following varicella infection.HACEK organisms (Haeophilus,Actinobacillus,Cardiobacterium,Eikenella,and Kingella fastidious) are less common causative organisms(8-9).Early diagnosis and accurate treatment is key in avoiding complications such as joint destruction,joint dislocation , ankylosis, growth arrest or spread of infection leading to osteomyelitis , pelvic abscess or nerve lesions.. Treatment is started without delay after synovial fluid and blood samples have been obtained. The classical presentation of septic hip arthritis in children is a combination of a painful hip joint with limited range of motion, fever, malaise and inability to bear weight on the affected limb. Misdiagnosis or inappropriate treatment of acute septic arthritis of the hip in children can result in devastating damage of the joint and possible lifelong disability. Open arthrotomy , drainage and thorough irrigation of the joint is considered the standard treatment for septic arthritis of the hip.Empiric antibiotic treatment primarily targets S. aureus and takes into account its resistance to antibiotics(10-11).
