Prevalence and clinical outcomes of hip fractures and subchondral insufficiency fractures of the femoral head in patients with tumour-induced osteomalacia

Purpose Tumour-induced osteomalacia (TIO) is a rare paraneoplastic syndrome usually caused by phosphaturic mesenchymal tumours, leading to great distress due to bone pain and affecting quality of life (QoL). This study aimed to investigate the prevalence and clinical outcomes of hip fractures and subchondral insufficiency fractures (SIF) of the femoral head.
