Pitfalls

Common pitfallsMissed diagnosis
Failure to recognise previous limping issues suggestive of chronic rather than acute disease.Developmental dysplasia of the hip, Perthes and juvenile idiopathic arthritis.
Not correctly localising the joint causing pain, for example, incorrectly diagnosing knee pain rather than hip pain.Slipped upper femoral epiphysis. 
Giving antibiotics before obtaining samples for culture in suspected septic arthritis/osteomyelitis.Potential failure to confirm diagnosis/identify organism.
Not identifying bone (as opposed to joint) as the source of pain and tenderness.Malignancy (haematological or primary bone tumour).
Not examining the abdomen and missing an intra-abdominal cause of ‘hip pain’.Appendicitis.
Not examining the testicles in boys.Testicular torsion.
Not checking for lymphadenopathy, hepatosplenomegaly and pallor.Haematological malignancy.
