Subcapital fracture
Updates to Article Attributes
Body
was changed:
Subcapital fracture is the commonest type of intracapularintracapsular fracture of the proximal femur. The fracture line extends through the junction of the head and neck of femur.
Classification
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.
Pre-reduction
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.
Types:
Type
-
type one is incomplete , stable and impacted
Type - type two is complete , stable and undisplaced
- type three is complete , unstable and partially displaced
- type four is complete , unstable and fully displaced
Post-reduction
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.
Types:
- < 30 degrees
- 30-70 degrees
- > 70 degrees
Complications
- avascular necrosis
- non-union
