Marcel, No experience here, but it seems logical to repair a pressure ridge the same way one would repair a crack. Cut away the damaged wood and fill with either a spruce shim or thickened epoxy. Like crack repair, this would be mostly cosmetic, although you might expect this action to prevent the rib separation that sometimes follows cracking.
