[Stimulation of bone healing with growth factors in orthopedic surgery].

Growth factors with specific effects on bone cells have been known of for more than a decade. Clinical usage of growth factors has recently become possible due to recombinant gene technology. In vivo studies over the last five years have demonstrated that growth factors can stimulate bone formation and bone healing and these results have made growth factors candidates for future clinical use in orthopaedic surgery. Growth factors for clinical use will become commercially available in the near future. The aim of this review paper is to describe the most important growth factors with effect on bone tissue and to give an updated review on experimental and clinical data on growth factor mediated bone healing in situations related to orthopaedic surgery. Possible areas for future clinical usage of growth factors are also discussed.
