A case of posterior HIP dislocation with intertrochanteric fracture: Beware of the sharp calcar spike

AbstractPosterior dislocation of hip is commonly associated with acetabular lip fractures. Involvement of neck, trochanter or intertrochanteric region is uncommon. Very few cases of posterior hip dislocation with ipsilateral intertrochanteric fracture in the absence of head or acetabular fracture ha...

Description
Summary:AbstractPosterior dislocation of hip is commonly associated with acetabular lip fractures. Involvement of neck, trochanter or intertrochanteric region is uncommon. Very few cases of posterior hip dislocation with ipsilateral intertrochanteric fracture in the absence of head or acetabular fracture have been reported in the literature. We report such a case in a 19yr male treated with open reduction and internal fixation with sliding hip screw with good functional and radiological outcome at 1 year. Being an extremely rare form of injury, such an injury pattern does not exist in present classification systems. There is a need to revise the existing classification systems and formulate a protocol for the management of the same. Such fractures may also be associated with a sharp calcar spike of the proximal fragment impinging femoral vessels and branches. Attempt at closed reduction without adequate anatomical orientation of the spike can lead to hazardous vascular consequences.
