Pediatric nontraumatic limp - differentiating transient synovitis from acute bacterial osteoarticular infection (septic arthritis, osteomyelitis) * Age and fever dictate differential for nontraumatic pediatric limp Causes of non-traumatic limp by age/presence of fever * Workup to consider: * Xrays * CBCD, CRP, blood culture if infection/inflammatory cause suspected to help distinguish between transient synovitis and osteoarticular infection * US (for effusion, soft tissues) if significant fever and/or elevation of inflammatory markers and/or severe pain * MRI with gadolinium is the most accurate noninvasive test for osteoarticular infection and should be considered for patients with persistent pain/fever Differentiating transient synovitis and acute bacterial osteoarticular infection * Volume of blood matters when obtaining blood for culture and sensitivity which is essential, as hematogenous spread is common in children with osteoarticular infections Expand to view reference list * https://www.cps.ca/documents/position/osteoarticular-infections-in-children * Peltola H. and Paakkonen M.
