Nonsurgical Corrective Union of Osteoporotic Vertebral Fracture with Once-Weekly Teriparatide

Abstract EN

Osteoporotic vertebral fractures usually heal with kyphotic deformities with subsidence of the vertebral body when treated conservatively.

Corrective vertebral union using only antiosteoporotic pharmacotherapy without surgical intervention has not been reported previously.

An 81-year-old female with osteoporosis presented with symptomatic fresh L1 vertebral fracture with intravertebral cleft.

Segmental vertebral kyphosis angle (VKA) at L1 was 20° at diagnosis.

Once-weekly teriparatide administration, hospitalized rest, and application of a thoracolumbosacral orthosis alleviated symptoms within 2 months.

Corrective union of the affected vertebra was obtained with these treatments.

VKA at 2 months after injury was 8° (correction, 12°) and was maintained as of the latest follow-up at 7 months.

Teriparatide has potent bone-forming effects and has thus been expected to enhance fracture healing.

Based on the clinical experience of this case, teriparatide may have the potential to allow correction of unstable vertebral fractures without surgical intervention.
