Method of implanting a glenoid assembly

Abstract

A method of implanting a glenoid assembly, includes forming a first bore in a glenoid region of a scapula and inserting a first peg of a glenoid component into the first bore. The method includes plastically deforming a first passageway within the first peg, while the first peg is inserted into the first bore, by inserting a first stiffening pin into the first passageway.

What is claimed is: 
     
         1 . A method of implanting a glenoid assembly, comprising:
 forming a first bore in a glenoid region of a scapula;   inserting a first peg of a glenoid component into the first bore; and   plastically deforming a first passageway within the first peg, while the first peg is inserted into the first bore, by inserting a first stiffening pin into the first passageway.   
     
     
         2 . The method of  claim 1 , further comprising:
 forming a second bore in the glenoid region of the scapula;   inserting a second peg of the glenoid component into the second bore; and   plastically deforming a second passageway within the second peg, while the second peg is inserted into the second bore, by inserting a second stiffening pin into the second passageway.   
     
     
         3 . The method of  claim 1 , further comprising:
 flexing the first peg in a direction toward a second peg to a flexed position, before inserting the first peg of the glenoid component into the first bore, wherein inserting the first peg of the glenoid component into the first bore comprises:   partially inserting the first peg of the glenoid component into the first bore while the first peg is in the flexed position.   
     
     
         4 . The method of  claim 3 , wherein inserting the first peg of the glenoid component into the first bore further comprises:
 releasing the first peg from the flexed position with the first peg partially within the first bore; and   fully inserting the first peg into the first bore after releasing the first peg from the flexed position.   
     
     
         5 . The method of  claim 4 , wherein:
 a shaft of the first peg defines a shaft diameter equal to FD and a shaft length equal to FL; and
   0.14<FD/FL<0.24. 
   
     
     
         6 . The method of  claim 5 , wherein 15.0 mm<FL<25.0 mm. 
     
     
         7 . The method of  claim 6 , wherein:
   19.0 mm<FL<21.0 mm;     0.16<FD/FL<0.22.   
     
     
         8 . The method of  claim 4 , wherein:
 the first passageway has a first minimum unbiased width (FUW); and
   0.6 mm<FUW<0.8 mm. 
   
     
     
         9 . The method of  claim 3 , wherein partially inserting the first peg of the glenoid component into the first bore while the first peg is in the flexed position comprises:
 inserting at least one fin of the first peg into the first bore.   
     
     
         10 . The method of  claim 3 , wherein flexing the first peg in a direction toward a second peg to a flexed position, before inserting the first peg of the glenoid component into the first bore, comprises:
 applying pressure to the first peg at a location between a fin of the first peg and a scapula-facing side of a base component of the glenoid component.   
     
     
         11 . The method of  claim 1 , wherein:
 the first passageway extends through of a base component of the glenoid component; and   inserting the first stiffening pin into the first passageway includes inserting the first pin through the base component and into the first passageway.
