In brief: Femur and bearing

A hip resurfacing and total hip both involve relining the inside of the socket.
A resurfacing does not remove the entire head, but rather caps the head with a cemented metal piece. A total hip does replace the entire head, and the head is attached to a piece of metal that goes down inside the femur 5 - 6". A critical difference is that a resurfacing requires a metal on-metal bearing (bad idea).

In brief: Placement of a stem

The "main difference" is that with a total hip arthroplasty a cut of the femur is made (osteotomy) and a stem is placed inside the femoral canal.
The hip ball is connected to this stem. With hip resurfacing the diseased femoral head (ball) is capped with a metal implant and the femoral neck is not cut.

In brief: The femoral implant

In hip replacement the part in the tight bone (femoral) fits inside the shaft of the bone.
In resurfacing, it covers the ball (femoral head), preserving more bone.
