1.8 mm VA Locking Buttress Pins

Douglas Campbell
The 1.8 mm variable angle (VA) locking buttress pins are used for fixation of complex intra- and extraarticular fractures and osteotomies of  the distal radius and other small bones. They are part of the VA-LCP distal radius system.
The VA locking head with T8 StarDrive recess allows the pin to lock up to 15 off-axis in any variable angle locking hole, or on-axis in any locking hole to provide angular stability at angles determined by the surgeon. The 1.8 mm diameter shaft is smooth and nonthreaded with a blunt, rounded tip which enables easy insertion and provides buttressing for the subchondral bone of complex and comminuted fractures. The rounded tip lowers tendon irritation when penetrating the far cortex. It also draws the surgeons attention to the principles of angular stability, where it is unnecessary for a locking screw or buttress pin to breach the far cortex at all. Leaving the tip of a locking screw or buttress pin just underneath the far cortex provides equal stability to engaging the far cortex with screw threads, particularly in osteopenic bone, thereby removing any risk of tendon irritation or injury. 4 mm of neck threads in the shaft aid in backing out the pin for easy removal.

The pins are available in titanium and stainless steel in lengths of 830 mm.
