A 6-year-old child presents with a painful limp and radiographs show slipped capital femoral epiphysis with posterior slip. What is the most appropriate next step in management?

• A. MRI
• B. Protective weight bearing + bracing
• C. Start Bisphosphonate
• D. TSH

Answer: (D)

Slipped capital femoral epiphysis is a surgical emergency—the priority is to prevent further displacement and avoid complications like avascular necrosis. The best next step is urgent stabilization of the slip with in situ fixation (typically a single cannulated screw) to lock the growth plate in place and halt progression. This should be done promptly after diagnosis.

Delaying for additional imaging (like MRI) or opting for only protective weight bearing would not address the instability and could allow the slip to worsen. Bisphosphonates don’t treat SCFE, and while endocrine evaluation (including thyroid function) is important, especially in very young patients or bilateral slips, it is part of a broader workup rather than the immediate management of the current slip.
