How would you differentiat a septic arthritis from an osteomyelitis
SEPTIC - ACUTE, non weightbearing, refuses to use limb
Pain on movement AND AT REST

Fever
OSTEOMYELITIS - SUBACUTE, non weightbearing, refuses to use limb

soft tissue redness and swelling may NOT be present and /or occur late
+/- fever
How does transient synovitis present?
Minimally painful limp in a child 3-8 years old - usually preceded by an URTI
WELL CHILD
Limited hip ABDUCTION and internal rotation
(often no investigations needed) - NORMAL XRAY (can have effusion on u/s)
Should return to normal in one to two weeks
Discharge with safety netting - ED if develops high fever, red, tender, swollen joint, unable to weight bear
Arrange to review in one week - if it doesn’t subside need to think of perthes or malignancy
Kochners criteria for septic arthritis
