Patent ID: 7582090

Claim:
A method for performing hip surgery, comprising the steps of: providing a prosthesis to be implanted, accessing the intramedullary canal of a femur, said intramedullary canal containing native and existing cancellous bone; providing a first tamp, said tamp having a shape substantially similar to that of the prosthesis to be implanted; impacting said first tamp into said native and existing cancellous bone of said intramedullary canal; removing said first tamp, thereby forming a first cavity having a shape substantially similar to that of the prosthesis to be implanted in said cancellous bone of said intramedullary canal, and repeating the providing a first tamp, impacting and removing steps with a series of at least two progressively larger tamps, each said tamp having a shape substantially similar to that of the prosthesis, said series including a final tamp, said final tamp having a size substantially similar to that of the prosthesis to be implanted in said intramedullary canal; such that when said final tamp is removed a final cavity having a size and shape substantially similar to that of the prosthesis to be implanted is formed in said native and existing cancellous bone for receipt of said prosthesis, each said tamp having a bore for receipt of an adjustment rod, wherein each said tamp has a transverse axis and said bore is at an acute angle with respect to said transverse axis to thereby position the adjustment rod for use in verifying anteversion via the adjustment rod in the bore, said bore formed through a side of said tamp adjacent a proximal end of said tamp, using said bore for said adjustment rod for determining the position of said tamp by fluoroscopy, and implanting the prosthesis into said final cavity without using bone cement.
