The Airlock® Ø3.0mm and Ø3.5mm locking and non-locking screws may be used in all Airlock plate fixation holes; however, the compression holes only accommodate Ø3.0mm non-locking screws. A Nexis Ø4.0mm headless compression screw of appropriate length may be used for additional plantar compression. All instrumentation is conveniently organized and color coded (see below).
