This is a case of a 24 year old man who had met with a vehicular accident and fractured his hip. The hip is a ball (femoral head) and socket (acetabulum) type joint and in this case, the acetabulum was fractured into 4 pieces. The reduction of this fracture was difficult because it was located on the posterior side and also one of the smallest fractured piece had been grossly dislocated and hence was obstructing the normal process.

The 3D CT scan did show this small piece but it could not delineate the origin of this piece. The model enabled to locate the origin of this piece. A few pre-operative trials were done on the model to arrive at its proper orientation. This reduced the surgery time and possibly avoided additional surgeries as well.
