A potential complication in critically ill patients is the formation of bone in soft tissues, termed heterotopic ossification. The exact pathogenetic mechanisms are still undetermined. Bone morphogenetic proteins induce bone formation, while signalling through the receptor activator of nuclear factor kappa-Β (RANK) and its ligand (RANKL), regulates osteoclast formation, activation, and survival in normal bone modelling and remodelling. Osteoprotegerin protects bone from excessive bone loss by blocking RANKL from binding to RANK.
