摘要

In this case,a male patient presented with a clinically and radiographically unstable slipped capital femoral epiphysis (SCFE) as well as slipped calcaneal epiphysis at the age of 23 years.Subsequent thorough work-up revealed that he had some features of rickets and laboratory test demonstrated he had hypophosphatemia (2.3mg/dl),normocalcemia,normal vitamin D metabolite levels,and secondary hyperparathyroidism.His family history,physical characteristics,along with confirmatory laboratory values indicated that the patient suffered from sporadic hypophosphatemic rickets.He was treated with oral phosphate (20～35mg elemental phosphorus/kg/d) and calcitriol (20～30ng/kg/d)with resultant dramatic clinical,biochemical,and histomorphologic improvement.This article describes the presentation,diagnostic work-up and treatment of our patient with a delayed-onset SCFE in the setting of hypophosphatemic rickets.We believe this is the first report of chronic SCFE and slipped calcaneal epiphysis that caused by hypophosphatemic rickets.
