Claim Text:
1. A femoral hip prosthesis configured to be implanted into a resected proximal end of a femoral bone and configured to receive a femoral head, comprising: a stem including a center longitudinal axis and a proximal end; a superior surface extending transversely relative to the center longitudinal axis from the proximal end of the stem; a neck defining a neck axis, the neck extending proximally from the superior surface such that the superior surface blends the stem and a base of the neck together, the neck extending proximally to a head connecting feature having a center point, the head connecting feature consisting essentially of structure for receiving the femoral head, the center point located within the structure for receiving the femoral head, the neck having a first length oriented along the neck axis to define a lateral extent, the neck extending relative to the stem to define a lateral offset distance, the lateral offset distance defined laterally between the center longitudinal axis of the stem and the center point of the head connecting feature; and an exterior bone-ingrowth portion having a proximal boundary extending adjacently parallel along the superior surface and extending distally over a portion of the stem, the proximal boundary extending distally at an angle to define an angled proximal boundary to cover the base of the neck, the first length of the lateral extent defined from the angled proximal boundary of the exterior bone-ingrowth portion to the center point of the head connecting feature; wherein the first length of the lateral extent ranges from 20% to about 50% of the lateral offset distance.
