Enhanced bone healing and decreased pain in sacral insufficiency fractures after teriparatide treatment: retrospective clinical-based observational study.

The purpose of this retrospective clinical-based observational study was to evaluate the effects of teriparatide (TPTD) on clinical outcomes and radiologic findings of sacral insufficiency fractures (SIFs). Seven elderly women with SIFs received TPTD for at least 6 months. We evaluated the symptoms, pain, and radiological findings. At their initial clinic visit, 86% patients could not walk or sit. Computed tomography (CT) images revealed sacral wing fracture in 6 patients, and bone scintigram showed H-shaped uptake over the bilateral sacral wings in 1 patient. After the treatment, 5 patients could walk. Mean visual analog scale score was significantly lower after (12.9 mm) than before (87.4 mm) TPTD treatment (p < 0.0001). CT images revealed bone union (four patients) and sclerotic changes (three patients) at the fracture sites. Seven elderly women with SIFs had significant improvement in pain and demonstrated bone union or sclerotic changes at fracture sites by TPTD.
