Teriparatide as nonoperative treatment for femoral shaft atrophic nonunion: A case report

BACKGROUND: Femoral shaft fractures are a common type of fracture among adults and have high union rates. However, clinical decisions are difficult to make because of the different types of nonunions. Atrophic nonunion usually requires revision surgery combined with bone grafting. Furthermore, no study of teriparatide administration for femoral atrophic nonunion have been previously reported. CASE SUMMARY: A 60-year-old woman had a right femoral shaft fracture due to a traffic accident, and she immediately underwent closed reduction and internal fixation surgery with an intramedullary nailing. However, after 6 mo of rehabilitation, the fracture site showed no signs of healing, and her condition was diagnosed as atrophic nonunion. Subsequently, teriparatide was administered for 6 mo. Complete union was observed at the fracture site 6 mo after teriparatide discontinued. CONCLUSION: The use of teriparatide can be a promising treatment to improve the healing of nonunion fractures.
