Abstract

This study examines the ability of osteoprotegerin (OPG) to prevent the local bone resorption caused by sciatic nerve damage. Sixty‐five 18‐week‐old male mice were assigned to one of six groups (n = 10–11/group). A baseline control group was sacrificed on day zero of the 10‐day study. The remaining groups were placebo sham operated, placebo nerve crush (Plac NC) operated, 0.1 mg/kg/day OPG + nerve crush (LOW), 0.3 mg/kg/day OPG + nerve crush (MED), and 1.0 mg/kg/day OPG + nerve crush (HI). Nerve crush or sham operations were performed on the right leg. The left leg served as a contralateral control to the nerve crushed (ipsilateral) leg. The difference in mass between the right and left femur and tibia was examined. Additionally, quantitative histomorphometry was performed on the right and left femur and tibia diaphyses. Nerve crush resulted in a significant loss of bone mass in the ipsilateral side compared to the contralateral side. Bone mass for the ipsilateral bones of the Plac NC group were significantly reduced by 3.8% in the femur and 3.5% in the tibia compared to the contralateral limb. The percent diminution was reduced for OPG treated mice compared to the Plac NC group for both the femur and tibia. In the femur, the percent reduction of ipsilateral bone mass was reduced to 1.0% (LOW), 1.3% (MED) and 1.6% (HI) compared to the contralateral limb. In the tibia, loss of bone mass in the ipsilateral limb was reduced to 1.4% (LOW), 1.4% (MED), and 2.4% (HI) compared to the contralateral. OPG also decreased the amount of tibial endocortical resorption compared to the Plac NC group. In summary, OPG mitigated bone loss caused by damage to the sciatic nerve. © 2001 Orthopaedic Research Society. Published by Elsevier Science Ltd. All rights reserved.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
