AbstractIn this study, we tested the effect of Teriparatide (PTH) in combination with β-tricalcium phosphate (β-TCP) as a bone void filler in an ovariectomised rat distal femoral metaphysis model.β-TCP is a completely resorbable synthetic calcium phosphate and the Teriparatide is a drug that can promote bone formation in the condition of osteoporosis. A critical size defect of 3mm in diameter, a through-hole bone defect, was drilled into each distal femur of the ovariectomised rats. The hole was filled with β-TCP and the rat was injected PTH Teriparatide (30μg/kg) in peritoneum 5 times per week. After 4and 8 weeks the animals were killed and the degree of bone healing analysed. In total, 60 animals were investigated. When the β-TCP and PTH were used, histological, biochemistry and histomor-phometric evaluations revealed significantly better bone healing in terms of quantity and quality of the newly formed bone. The Ovariectomised rats which suffer from femur metaphysis defect are cured by embedding β-tricalcuim phosphate and intermittently cured by parathyroid hormone (PTH). Copyright © 2015 Elsevier Ltd.
