Subcapital fracture

Subcapital fracture is the commonest type of intracapsular fracture of the proximal femur. The fracture line extends through the junction of the head and neck of femur.


Although many classifications are proposed Garden classification and Pauwel classification are generally followed from a practical point of view as these two systems take into consideration stability of the fractures.


Garden classification is based on the pre-reduction displacement of the femoral head. Further the displacement is graded as per position of the principal (medial) compressive trabeculae.

  • type I: is incomplete, stable and impacted
  • type II: complete, stable and undisplaced
  • type III: complete, unstable and partially displaced 
  • type IV: complete, unstable and fully displaced

Pauwel classification is based on post-reduction angulation of fracture line to the horizontal evaluated on a AP radiograph.

Lesser the angulation more stable the fracture with a better a prognosis.

  • <30 degrees
  • 30-70 degrees
  • >70 degrees
