Posterior dislocation of hip with ipsilateral subtrochanteric fracture of femur in a child: a very rare case report

Abstract

In children, traumatic hip dislocations although rare, but are more common than hip fractures. Trivial injuries may cause a hip dislocation in young children because of their immature pliable cartilage and lax ligament. Subtrochanteric femoral fractures occur below the lesser trochanter to 5 cm distally in the shaft of the femur. In young and healthy individuals, the injury usually results from high-energy trauma. Posterior dislocation of hip with subtrochanteric fracture is very rare and it usually results due to a significant injury. We report a case of nine year old child, presenting with posterior dislocation of hip with ipsilateral subtrochanteric fracture of left femur. Such types of injuries are not fitting into any present system of classifications.
