Summary
The electrical behaviour of the exposed tibial surface of young rats has been studied in normal conditions, after fracture and during the repair process. Recordings of potentials were made after all the electrical artefacts (muscle injury potentials) had been neutralized. No significant potential difference was obtained on the exposed bony surface in all the specimens. The results suggest that the currents of the hypothetical “bone-generator” do not reach the tibial surface. The bioelectrical properties of bone cannot therefore be investigated by an external recording method.
Résumé
Les auteurs ont étudié le comportement électrique des surfaces osseuses tibiales exposées sur de jeunes rats, en condition normale, après fracture et pendant le processus de réparation. L'enregistrement des potentiels a été fait après neutralisation de tous les artefacts électriques (potentiels de lésion musculaire). Aucune différence de potentiel n'a été enregistrée au niveau des surfaces osseuses exposées, dans chacune des conditions.
Ces résultats indiquent que les courants de l'hypothétique »g'enérateur osseux« ne parviennent pas à la surface du tibia. Donc aucune méthode d'ènregistrement externe des propriétés bio-éléctriques de l'os n'est possible.
