Tamp for concave resurfacing prosthesis

Abstract

A tamp for use in forming grafting material into a cavity in the glenoid vault to prepare the vault for a glenoid component for performing shoulder arthroplasty is provided. The tamp includes a body and a forming portion. The forming portion extends in a first direction from the body. The forming portion including a surface thereof shaped to receive the glenoid component.

1 . A tamp for use in forming grafting material into a cavity in a glenoid vault to prepare the vault for a glenoid component for performing shoulder arthroplasty, said tamp comprising: 
 a body; and    a forming portion extending in a first direction from said body, said forming portion including a surface thereof shaped to receive the glenoid component.    
   
   
       2 . The tamp of  claim 1 , wherein the surface of said forming portion has a shape substantially similar to a surface of the glenoid component.  
   
   
       3 . The tamp of  claim 2 , wherein said body has a generally cylindrical elongated shape.  
   
   
       4 . The tamp of  claim 2 , further comprising a handle extending from said body in a second direction opposed to the first direction.  
   
   
       5 . The tamp of  claim 4 , wherein said handle further includes a striking surface for striking the tamp, the striking surface being perpendicular to a longitudinal axis of said handle.  
   
   
       6 . The tamp of  claim 2 , wherein the surface of said forming portion has an oval shape.  
   
   
       7 . The tamp of  claim 2 , wherein said body and said forming portion are integral with each other.  
   
   
       8 . A tamp for use in forming grafting material into a cavity in a glenoid vault to prepare the vault for a glenoid component for performing shoulder arthroplasty, said tamp comprising: 
 a body;    a forming portion extending in a first direction from said body, said forming portion including a surface thereof shaped to assist in tamping the graft material into a shape to matingly receive the glenoid component; and    a handle extending from said body in a second direction opposed to the first direction.    
   
   
       9 . The tamp of  claim 1 , wherein said body, said forming portion, and said handle are integral with each other.  
   
   
       10 . The tamp of  claim 1 , wherein the surface of said forming portion has a shape substantially similar to a surface of the glenoid component.  
   
   
       11 . The tamp of  claim 1 , wherein said body has a generally cylindrical elongated shape.  
   
   
       12 . The tamp of  claim 4 , wherein said handle further includes a striking surface for striking the tamp, the striking surface being perpendicular to a longitudinal axis of said handle.  
   
   
       13 . The tamp of  claim 1 , wherein the surface of said forming portion has an oval shape.  
   
   
       14 . A tamp for use in forming grafting material into a cavity in a glenoid vault to prepare the vault for a glenoid component for performing shoulder arthroplasty, said tamp comprising: 
 a body;    a forming portion extending in a first direction from said body, said forming portion including a surface thereof having a shape matching the glenoid component; and    a handle extending from said body in a second direction opposed to the first direction.    
   
   
       15 . The tamp of  claim 14 , wherein said forming portion has a generally inverted dome shape including a generally oval cross-section.  
   
   
       16 . The tamp of  claim 14 , wherein said forming portion has a continuously decreasing width in a direction opposed to said handle.  
   
   
       17 . The tamp of  claim 14 , wherein said body has a generally cylindrical elongated shape.  
   
   
       18 . The tamp of  claim 14 , wherein said handle further includes a striking surface for striking the tamp, the striking surface being perpendicular to a longitudinal axis of said handle.  
   
   
       19 . The tamp of  claim 14 , wherein the surface of said forming portion has an oval shape.  
   
   
       20 . The tamp of  claim 14 , wherein said body, said forming portion, and said handle are made of a material selected from the group including a titanium alloy, a cobalt chromium alloy, and a stainless steel alloy.
