Résistance des réparations microchirurgicales des sections des nerfs collatéraux à la mobilisation digitale – étude anatomique

The aim of this study was to test resistance to mobilisation of microsurgical repair of collateral nerves. Thirty-nine collateral digital nerves of fresh forearms cadavers were transected then sutured using 10 0 nylon. After skin closure, each finger was mobilised forcefully in flexion extension ten times around. Two nerves were elongated and 4 were ruptured, this amount to a 15.38% complication rate. In conclusion, we recommend immobilisation of nerve repairs, in contradiction with most recent studies.
