Of the 224 patients who were randomized, 171 (86 teriparatide, 85 risedronate) were included in the analysis. The teriparatide group completed the TUG test in a shorter time at 6, 12, 18, and 26 weeks.
They also reported less pain on a visual analog scale immediately after the TUG test at 12 and 18 weeks. Radiographic healing at 6, 12, and 26 weeks, mechanical failure of the implant (teriparatide, 7; risedronate, 8), loss of reduction (teriparatide, 2; risedronate, 4), and nonunion (0 cases) were not significantly different.
