Kwire Depth Gauge The Impact PEEK Union Nail System is indicated for maintenance of alignment and fixation of bone fractures, osteotomies, arthrodeses or bone grafts in the presence of appropriate additional immobilization (e.g. rigid fixation implants, cast, brace). The Impact PEEK Union Nail System contains 3.0mm - 4.5mm diameter, 50mm long pins manufactured from HA Enhanced PEEK (ASTM F2026). The implants are designed with strategically placed ridges to improve initial stability and cannulated structure to simplify insertion over a k-wire. Additionally, it was designed to include tantalum pins to ensure optimal imaging visibility for device placement accuracy.
A surgical instrument designed to measure the depth of a recess, usually to measure the depth of holes being drilled in bone so that the surgeon can determine the length of the bone screw to be used. It may take two forms: 1) a device with a moveable (sliding) centrepiece (a prong), the tip of which is inserted into the recess to read from a scale; 2) a circular disc with a central hole which is clipped to a drill bit so that the device slides up as the drill bit is advanced. This is a reusable device intended to be sterilized prior to use.
