A method for repairing bone in a bone cavity delimited by healthy bone faces, and from which traumatized bone has been excised, comprises adjusting a flexible, biocompatible mesh fabric tube to fit the bone cavity and contact the healthy bone faces and filling the mesh tube with a bone graft. A bioresorbable coating is applied to the tube to rigidify the tube having been adjusted in shape to fit the bone cavity. The coating seals the mesh against graft movement through the mesh of the tube until the bioresorbable coating has been resorbed. The tube is inserted within the bone cavity and the coating is resorbed to allow the graft to pass from the interior of the tube, through the mesh, to the healthy bone faces.
