The test revealed abnormal uptake indicating inflammation at each Chopart joint, the left talar dome, the internal left knee, the right femoropatellar joint, and finally the upper left coxofemoral joint (Figure 1).
Pelvic X-ray, anteroposterior view. Basicervical fracture of the right femur.

Six months after partum, the patient's coxalgia had worsened, leading her to undergo new standard X-rays that demonstrated a fracture of the right femoral head complicated by a spontaneous basicervical fracture (Figure 2) treated with osteosynthesis.
Bone biopsy of the iliac wing with double tetracycline labelling. Active, highly intense resorption via very small osteoclasts, especially in the periosteal region.

It revealed trabecular and cortical osteoporosis with active, highly intense hyperabsorption, especially subperiosteally, by very small osteoclasts (Figure 3) and normal or accelerated formation indicating coupled hyperremodelling.
