INTRODUCTION

• Stress fractures are an overuse injury of bone
  due to repetitive microtrauma.
• Fatigue fracture abnormal stress on normal bone.
• Insufficiency fracture normal stress on abnormal
  bone.
• The first stress fracture was described by
  Briefhaupt in 1855.4
• Acetabular stress fractures are exceedingly rare.
• Although the exact incidence is unknown, pelvic
  stress fractures account for 1-2 of all stress
  fractures.2
• Acetabular fracture from any cause (usually high
  velocity trauma) is also rare, incidence of
  0.5-7.5.3
• Stress Fractures in any location are twice as
  common in women than men.4
• Extrinsic risk factors for stress fractures
• Overuse
• lack of conditioning
• poor technique
• inappropriate footwear
• nonabsorbent training surface
• Intrinsic risk factors for stress fractures
• muscle imbalance
• Malalignment
