Fracture of the Lesser and Greater Trochanter Wheeless

Description: - Lesser Trochanteric Fracture:
- isolated fracture of the lesser trochanter is quite rare but may develop as a result of the avulsion force if the iliopsoas muscle;
- it occurs commonly as a component of intertrochanteric fracture;
- fracture of the lesser trochanter along with a subtrochanteric or intertrochanteric fracture is by definition unstable;
- Greater Trochanteric Fracture:
- isolated fracture of the greater trochanter may be caused by direct injury or may occur indirectly as a result of the activity of gluteus medius and gluteus minimus muscles
