<p>An acetabular trial system [10] comprises a first reamer [42], a second reamer [12] and a liner [14]. The first reamer [42] has a first diameter [50] and is configured to ream an acetabulum. The second reamer [12] has a second diameter [30] larger than the first diameter [50] and is configured to ream the acetabulum. The liner [14] is configured to mate to the second reamer [12] such that when an acetabulum is reamed by the first reamer [42], the second reamer [12] is sized as a trial shell component. The second reamer [12] is capable of impaction into the acetabulum and reception of the liner [14] such that the liner [14] and the second reamer [12] are configured to trial the acetabulum for size and orientation relative to a femoral component of a hip prosthesis.</p> |
