cortical nuts

When threads strip or where bone density is poor, a stainless steel or UHMWPE cortical nut can be used to provide thread anchorage and salvage the situation. Stainless steel nuts are stronger, but UHMWPE is self-locking.

Occasionally tapped threads strip and a larger screw is appropriate. Lag screws are particularly vulnerable as only one cortex is available. A Cortical Nut manufactured from implant grade nylon gives the screw purchase allowing normal tightening. The thread form is designed to grip the screw to minimise ‘backing out’. Available in 2.0mm, 2.4mm, 2.7mm, 3.5mm and 4.5mm cortical thread forms. Supplied as a single sterile pack. The Cortical Nuts are also available in Stainless Steel.
