The effect of clodronate on healing of the fracture of osteopenic bone was studied in rats. A total of 165 female rats (14 +/- 1 weeks, 216 +/- 2 g) were divided into five fracture groups (n = 30), and a neurectomized group (n = 15). Osteopenia (op) was induced by right sciatic neurectomy 4 weeks before the fracture. ⋯ Clodronate did not affect normal bone strength. In conclusion, clodronate did not affect the bending strength of op fracture nor the strength of the control bones. The remodeling of the fracture was delayed with clodronate.
