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%
