case_images: II Pipkin fracture following a motorcycle accident (Figure 1). In the emergency department, an emergent close reduction under fluoroscopy was performed, followed by definitive surgical treatment five days after the initial injury.
case_images: Intraoperative exposure of the femoral head through a surgical hip dislocation approach and intraoperative assessment of femoral head vascularization performed with K-wire perforation.

case_images: Regarding the Pipkin fracture, we chose to perform an anatomical reduction and internal fixation (Figure 2), using a surgical hip dislocation as described by Ganz et al.. We additionally verified the viability for the femoral head, performing perforations with a small K-wire as preconized in literature (Figure 2).

case_images: The osteosynthesis was achieved using three subchondral headless cannulated screws (Figure 3), the capsule was closed with Vicryl 2-0 sutures, and the greater trochanter stabilized using two 3.5 mm cortical screws (Figure 4).

case_images: Simple anteroposterior radiograph showing supratrochanteric heterotopic ossification at 3 years of follow-up, with a good active motion of the hip and painless hip flexion.

case_images: Five months later, the patient was able to walk without crutches and painless range of motion (Figure 5). Nonetheless, a Brooker grade II heterotopic ossification could be identified in the radiographs (Figure 5).
