Slipped Capital Femoral Epiphysis
SCFE

  • Rare less than nine years of age  

  • Boys more than girls  

  • Plain of cartilage changes during adolescence to more a more oblique one predisposing to easier slipping  

  • Higher incidence of slip from June through September

  • Usually boys

    • Blacks more often

    • Ages 10 through 15

    • Usually heavier and or taller than others for their age  

  • Younger in girls 8 to 15 years of age  

  • About 20 to 25 percent are bilateral, an occurrence more frequent in girls.  

  • Imaging Findings 

    • Osteoporosis of head and neck on AP view early

    • Indistinct epiphysis-widened

    • Line along lateral edge of superior femoral neck on AP doesn't intersect epiphysis

    • Metaphysis displaced laterally so that it does not overlap posterior lip of acetabulum as normal

    • Late buttressing medial and posterior on neck  

  • Sequelae

  • Degenerative arthritis

  • Varus deformity

  • Avascular necrosis 6 to 15%
