It's been a very long week or two.
The boy I saw last week with hip pain turned out to have Slipped Capital Femoral Epiphysis. This is a diagnosis that is easy to miss .. and I didn't know that he had it when I saw him. The x-ray didn't show anything .. which was reassuring .. though his pain persisted .. which prompted a referral to orthopaedics.
The orthopod ordered more views of the hip .. one of which showed the SCFE .. prompting surgery.
