Artikel 10

1. Injured workmen shall be entitled to the supply and normal renewal, by the employer or insurer, of such artificial limbs and surgical appliances as are recognised to be necessary: provided that national laws or regulations may allow in exceptional circumstances the supply and renewal of such artificial limbs and appliances to be replaced by the award to the injured workman of a sum representing the probable cost of the supply and renewal of such appliances, this sum to be decided at the time when the amount of compensation is settled or revised.
2. National laws or regulations shall provide for such supervisory measures as are necessary, either to prevent abuses in connection with the renewal of appliances, or to ensure that the additional compensation is utilised for this purpose.
