Miniplate washers for improving lag screw fixation.
Increased efficiency in using the lag screw principle for rigid fixation of bone, particularly for fragile cortical or soft cancellous grafts, is facilitated by dispersion of screw head compression forces with a biocompatible metallic washer. Although none is commercially available, such washers may be quickly fashioned from the residua of any adaptation miniplate in quantities as required.
