Cement Punch

Traditional cement techniques are problematic in getting reliable cement penetration into bone. Cancellous bone such as of the proximal tibia is variable with respect to its porosity. The bone near the surface and edges of the tibial is less porous and more dense than deeper bone such as the bone near the keel of the implant. Therefore, with traditional cement techniques of either applying the cement to the bone or implant and then compressing with impaction of the implant, there may be inadequate cement penetration at the critically important surface and edges of the tibia. In fact, most of the cement with these techniques gets expressed out the sides with minimal bone penetration. WHAT IS CEMENT PUNCH The Cement Punch was specifically designed to get a uniform 5 mm of cement penetration regardless of bone density. The patented pattern of cells in the Cement Punch compartmentalize the cement and force it to be injected into the bone without allowing it to flow to areas of less porosity. The Cement Punch allows for a customized amount of injection pressure on the cement in each cell to allow for uniform penetration in either dense or porous bone.
