Bilateral hip heterotopic ossification with sciatic nerve compression on a paediatric patient–An individualized surgical approach: A case report

Figure 1 Antero-posterior pelvic radiograph showing extensive bilateral heterotopic ossification.

Figure 2 Computed tomography showing a bilateral bony bridge between the ischium and postero-medial proximal femur that limits hip range of motion.

Figure 3 Computed tomography and axial view. A: A proximal section showing ossification of the gluteal and posterior thigh musculature; B: A distal section showing ossification around the sciatic nerve.

Figure 4 Intraoperative views. A: Lazy “S” incision in the gluteal region; B: Resection of ossified lesions; C: Release of the sciatic nerve path.

Figure 5 Radiograph. A: Radiograph obtained immediately after left hip resection, note the regrowth of ossification on the right hip, which was treated first; B: Radiograph at 1 yr after surgery shows limited regrowth of heterotypic ossification on the right hip with signs of cortical maturation.
