Preoperative images of the right diaphyseal Winquist and Hansen type II femur fracture. Note the lateral butterfly fragment, and the relatively transverse fracture through the medial cortex.

The fracture had a small lateral butterfly fragment, with otherwise a simple transverse fracture through the medial cortex, Winquist and Hansen Type II fracture (Figure 1).
Anteroposterior CT scout image of the right femur. The cortical widths of the medial proximal and distal fragments appear to be equal.

On the antero-posterior scout CT image the cortical widths of the medial proximal and distal fragments were equal (Figure 2).
Axial cuts through femoral neck and condyles. Modified Jeanmart technique revealed 15  of external rotation of the right femur relative to the unaffected left femur.

However, applying the technique described by Jeanmart et al. to the axial cuts of the same CT scan, we measured a rotational deformity of 15  external rotation for the right femur (Figure 3).

In the axial plane, the distal Steinmann pin was inserted in 15  of external rotation relative to the proximal one (Figure 4).

He made an uncomplicated recovery thereafter (Figure 5).
