Patient examination

In case of comminution, the assessment of rotation is exceedingly more difficult.

Limb length can be established by preoperative measurement of the contralateral limb.

Rotation can be assessed with a physical examination of the contralateral extremity and radiographs of the femur and hip to create a preoperative template.

One method of preoperative radiographic templating is to obtain a direct lateral radiograph of the knee and a radiograph in the AP plane of the hip at 90° orthogonal to the first knee x-ray.

The profile of the lesser trochanter should be radiographically similar once reduction is complete.
