Osteoporosis drug treatment after fracture

Abstract

The prevalence of osteoporosis, especially among the elderly, is increasing exponentially, leading to an increase in the number of fractures and disability. As a result, new requirements for anti-osteoporotic therapy appear, associated with its influence not only on the remodeling of healthy bone, but also on the acceleration of fracture consolidation. The article provides a brief overview of the effect of various anti-osteoporotic drugs on the healing of bone fractures. An assessment of the consolidating effect of antiresorptive drugs — bisphosphonates and denosumab, and anabolic drug — teriparatide, monoclonal antibodies blocking the protein sclerostin, strontium ranelate is given. The use of antiresorptive drugs did not affect, according to the literature, the slowing down of consolidation after fractures of various parts of the skeleton (hip, vertebrae, distal radius). The introduction of anabolic drugs, in particular teriparatide, is accompanied by faster healing of fractures in comparison with the timing of natural bone regeneration or the intake of bisphosphonates, causing an improvement in the formation of callus. The use of drugs that block sclerostin also increases bone formation and bone strength. Based on the available data, it can be concluded that fractures should not be considered as a contraindication to the use of these drugs and be the reason for the late initiation of drug treatment of osteoporosis.
