1. A resilient orthopedic implant comprising:
a. a first wall configured to engage an articulating end of an acetabulum of a pelvic bone;
b. a second wall configured to conform around a portion of a femoral head, the second wall having one or more appendages configured to secure the second wall to the femoral head;
c. a side wall extending between the first wall and the second wall and configured to facilitate relative motion between the first and second walls; and
d. an interior portion configured to be directly enclosed by the first wall the side wall, and a proximal end of the femoral head;
wherein some length of the first wall overlaps some length of the second wall creating a fold in the implant such that some length of an exterior surface of the side wall has a concave shape at the fold; and
wherein the implant is configured for deployment between the femoral head and the acetabulum of the pelvic bone when neither the femoral head nor the pelvic bone is resected.
