The effect of heparin and the LMWH, Tinzaparin, on osteoclast surface and erosion depth. Rats were injected with increasing concentrations of either unfractionated heparin or LMWH and the percentage of cancellous bone surface covered with osteoclasts (A) and/or erosion depth (B) determined. Data are expressed as mean ± SEM. aP < .005 when compared with either baseline or control values. bP < .01 when compared with values obtained from LMWH-treated animals.
