Laboratory result and imaging was consistent with hypophosphataemic osteomalacia. He had bilateral femoral neck non-union and presented with a new left side subtrochanteric femoral fracture. Corrective osteotomy and cephalomedullary fixation was performed. The fractures healed in 6 months after correction of the hypophosphataemia.
