Cemented- The cemented hip implant is designed to be implanted using bone cement (a group that helps position the implant within the bone). Bone cement is injected into the prepared femoral canal. The surgeon then positions the implant within the canal and the grout helps to hold it in the desired position.
Uncemented- The porous hip implant is inserted into the prepared femoral canal without the use of bone cement. Initially, the femoral canal is prepared so that the implant fits tightly within it. The porous surfaces on the hip implant are designed to engage the bone within the canal and permit ingrowth into the porous surface. Eventually, this growth can provide additional fixation to hold the implant in the desired position.
