INTERFACE™ NP (No Point) Fixation Half-pins,
Standard (cortical) Thread Profile
INTERFACE™ NP fixation half-pins lack the trocar point found on standard INTERFACE™ pins. Pre-drilling is required for pin placement. As with application of any ESF pin, attention should be given to proper pin alignment with the pre-drilled hole. Use of the SK™ ESF clamp’s secondary bolt will keep the clamp and drill hole oriented. In addition, liberal soft tissue release and retraction will simplify pin placement by allowing visualization. Absence of a trocar reduces opportunity for morbidity created by a trocar point remaining in soft tissue. This trocar-free pin is also safer for the operating surgeon. The lack of a trocar point makes this pin less expensive than trocar pointed INTERFACE™ pins. Lengths, diameters, and recommended drill bits are common with standard INTERFACE™ pins. IMEX™ pin and drill charts can be used for trocar and no point (NP) versions.
All INTERFACE™ fixation half-pins are produced from the highest quality, implant grade 316LVM stainless steel.
All can be utilized with acrylic or epoxy frames.
All sizes can be accommodated with the SK™ ESF System.
15020NP (2.0mm shank) is the largest pin recommended for the Mini SK™ ESF clamp, and is particularly advantageous with European fixator systems that utilize 2.0mm fixation pins.
