Sulci protectors are ideal for straightening, mending and shaping the side edges of the nail and for cushioning the nail against irritation or inflammation from the nail wall. They offer a distinct advantage over packing, especially for ingrown toenails. They can be left in place for up to eight weeks (must be re-fixed after four weeks). The splints do not just provide a cushion, they also have the effect of maintaining the normal width and shape of the nail at the free edge. That prevents changes to the nail bed, protrusion of the nail wall and the resulting deformities and growth disorders of the nail. Sulci protectors are available in three different sizes. Sulci protectors can be positioned using tweezers or a Sulci injector. GEWOHL Nail Compound is the ideal fixative for the protector.
