We medicated teriparatide in three patients, who had a nonunion of the femur even after the initial surgical intervention. Teriparatide was administered for 3-9 months after a diagnosis of nonunion. A successful union was obtained in all three patients without further surgical intervention, and no adverse events related to the use of teriparatide were observed. Our report showed that teriparatide could be an alternative to surgical intervention in nonunion of the femur.
