Interface Fixation Half-pin, No-Point, Standard Threads, End Threaded

Interface Fixation Half-Pin, Standard Threads, No-Point

 

Interface NP (No-point) fixation half-pins lack the sharp trocar point found on standard Interface pins. Predrilling is required for pin placement.

Available in standard and extended length. Standard length pins are used in the majority of applications while extended length pins are occasionally used when additional thread length is needed to span areas of larger bone diameter. Part numbers ending with "L" indicate extended length pins.

Implant quality 316LVM, stainless steel

Additional Product Information

As with application of any ESF pin, attention should be given to proper pin alignment with the predrilled 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.The blunt trocar reduces the opportunity for morbidity created by a sharp point remaining in soft tissue. This truncated trocar pin is also safer for the operating surgeon. The lack of a sharp point makes this pin less expensive than a full trocar pointed Interface pin.

FAQs

  • Is there a sequence and technique for placement of subsequent pins?

    Typically, the third and fourth pins placed into an ESF frame are the two pins on each side and closest to the fracture. This is not mandatory; however, it is easier to verify accuracy of reduction and ensures good pin placement. These pins are placed via liberal release incisions and through pre-drilled holes. Placing the SK clamp over the area of soft tissue release, and using the secondary bolt to secure it in perfect alignment for the desired drill hole and pin position ensures correct targeting and pin placement. Next, the appropriate drill sleeve is passed through the primary pin-gripping bolt to protect the soft tissue as the bone is pre-drilled. One must be careful not to crush the thin-walled drill sleeve by tightening the primary pin-gripping bolt more than just enough to hold the sleeve in position. Pre-drilling is performed through the drill sleeve while exercising care not to exert undue pressure on the drill bit. Excess pressure results in drill bit flexing and a sudden “push through” of the drill bit into the opposite soft tissues as it breaks through the bone. The drill sleeve is then removed and low-speed insertion of the fixator pin is performed. After placing pins three and four, recheck reduction and alignment before placing additional pins. Repeat this procedure for as many additional pins as desired.
