1. A component configured for implantation during a total hip replacement procedure being performed on a patient, the patient having an anterior and posterior and defining a sagittal plane, a transverse plane and a coronal plane, the component comprising:
a stem configured for intraosseous femoral implantation, the stem having a distal end configured for femoral insertion and a proximal end opposite the distal end; a neck-stem junction platform comprising a neck portion and a stem portion opposite the neck portion, the stem portion connected with the proximal end of the stem at a stem connection point, the neck-stem junction platform configured for extraosseous femoral implantation without any intraosseous implantation, wherein the neck portion and the stem portion form an L-shaped platform; a neck attached to the stem by the neck-stem junction platform, the neck having a proximal end connected with the neck portion of the neck-stem junction platform at a neck connection point and a distal end opposite the proximal end, the neck configured for extraosseous femoral implantation; wherein the stem portion of the neck-stem junction platform defines a lateral-medial axis through the stem connection point and the neck portion of the neck-stem junction platform defines a posterior-anterior axis through the neck connection point, the lateral medial axis and the posterior-anterior axis intersecting at an intersection point and being substantially perpendicular to each other; wherein the stem connection point is a lateral-medial distance parallel to the lateral-medial axis from the intersection point; and wherein the stem connection point is a posterior-anterior distance parallel to the posterior-anterior axis from the intersection point; and a head attached to the neck proximate the distal end of the neck, the head configured for coupling with a socket implanted in an acetabulum of a pelvis of the patient during the procedure, thereby forming a total hip replacement. |
