Abstract
An orthopaedic surgical instrument and method for positioning an acetabular prosthetic component in a patient's surgically-prepared acetabulum is disclosed. The orthopaedic surgical instrument has a base configured to engage the patient's pelvis, a first linkage pivotally coupled to the base, a locking mechanism operable to lock the first linkage in position relative to the base, and a second linkage removably coupled to the first linkage. The second linkage has an alignment axis corresponding to a desired abduction angle and a desired anteversion angle of the acetabular axis of the acetabular prosthetic component.
Claims1
An orthopaedic surgical instrument for positioning an acetabular prosthetic component in a patient's surgically-prepared acetabulum, the instrument comprising:
- a base including a plurality of mounting legs configured to engage the patient's pelvis,
- a first linkage pivotally coupled to the base,
- a locking mechanism operable to lock the first linkage in position relative to the base, and
- wherein the first linkage includes an indicator operable to provide a visual indication of a position of the instrument, and the instrument further comprises a second linkage removably coupled to the first linkage, the second linkage having an alignment axis corresponding to a desired abduction angle and a desired anteversion angle of the acetabular axis of the acetabular prosthetic component.
