Trochanteric fracture
Updates to Article Attributes
Trochanteric fracture is a fracture involving the greater and/or lesser trochanters of the femur.
Classification
Fractures in these regionregions can be classified as:
- intertrochanteric
- pertrochanteric: intertrochanteric, involving both trochanters
- subtrochanteric
- greater trochanteric avulsion fracture
- lesser trochanteric avulsion fracture
Intertrochanteric fracture
They are subdivided according to the number of fragments, as follows:
- two-part linear intertrochanteric fracture stable
- three-part with comminution of lesser trochanter or greater trochanter
- four-part with comminution of both trochanters
- multi-part with comminution of both trochanters and intertrochanteric region
The Boyd and Griffin classification is based on the involvement of subtrochanteric region:
- type I linear intertrochanteric
- type II with comminution of trochanteric region
- type III with comminution associated with the subtrochanteric component
- type IV oblique fracture of the shaft with extension into the subtrochanteric region
SubtrochontericSubtrochanteric fracture
The Fielding classification of subtrochanteric fractures is based on the level of the subtrochanteric region through which the fracture extends:
- type I: at the level of the lesser trochanter (most common)
- type II: within the region 2.5 cm below the lesser trochanter
- type III: within the region 2.5 cm to 5 cm below the lesser trochanter (least common)
The Zickel classification (modified from Fielding) of subtrochanteric fractures takes into consideration the level and obliquity of the fracture line as well as the presence or absence of comminution.
- type I short oblique
- linear
- comminuted
- type II long oblique
- linear
- comminuted
- type III transverse
- high level
- low level
Treatment and prognosis
Subtrochanteric fractures generally have a good prognosis due to the good supply of blood and adequate collateral circulation to this region of the femur with a low incidence of avascular necrosis and non-union. Postoperative infection, however, is a potentially serious compilation.
