Howmedica's Locking Nail Systems consist of different styles of femoral, tibial and humeral nails. This line extension is to add a new type of cross-locking screw to be used with the currently marketed Grosse & Kempt® nails, Gamma® nails and Seidel™ nails cleared under various 510(k) notifications plus any future styles of stainless steel IM rods or nails. The new screw is 4.6 mm in diameter and is available in various lengths. It has a cortical buttress thread design for transverse cross-locking of IM nails. The screws are manufactured from medical grade stainless steel.
The Howmedica® Fully Threaded Screws are intended to be used for cross-locking of femoral, tibial and humeral locking nails and IM rods.
The substantial equivalence of these components is based on an equivalence in intended use, materials, design, and operational principles to Zimmer's Buttress Thread Screws and Zimmer's ZMS Recon Nail Cross-Locking Screw.
