FEMORAL COMPONENT FOR A HIP PROSTHESIS |
摘要 |
A femoral component for a hip prosthesis has a proximal end for disposition at a superior position in a femur and a distal end opposite the proximal end. The femoral component has opposite medial and lateral sides and opposite anterior and posterior faces extending between the medial and lateral sides. At least a proximal part of the femoral component has a first superior-to-inferior taper so that a medial to lateral dimension decreases gradually from the proximal end toward the distal end, a second superior-to-inferior taper so that an anterior to posterior dimension of the femoral component decreases gradually from the proximal end toward the distal end and a lateral-to-medial taper so that an anterior to posterior dimension of the femoral component decreases gradually from the lateral side toward the medial side. |

1. A femoral component for a hip prosthesis having a proximal end for disposition at a superior position in a femur and a distal end opposite the proximal end, the femoral component having opposite medial and lateral sides, an anterior face and a posterior face substantially opposite one another and extending between the medial and lateral sides, at least a proximal part of the femoral component having a first superior-to-inferior taper so that a medial to lateral dimension of the femoral component decreases gradually from the proximal end toward the distal end, a second superior-to-inferior taper so that an anterior to posterior dimension of the femoral component decreases gradually from the proximal end toward the distal end and a lateral-to-medial taper so that an anterior to posterior dimension of the femoral component decreases gradually from the lateral side toward the medial side. |
