Hi, nanceyellen,
I'm sorry you are confused. Yes, a femur ball "replacement" is the
same as a total hip replacement. A hip replacement is surgery to
repair the diseased hip joint. The hip joint is a ball and socket
joint. Therefore, the "ball" at the head of the femur (thigh) is
replaced with an artificial "ball" in a hip replacement.
*** Unless you have had a procedure called "Hip resurfacing" which
covers the diseased "ball" with a metal shell, you are likely talking
about total hip replacement.***
You say you still have your own "hip bones." In a total hip
replacement, the only bone that is replaced is the actual ball. Your
pelvis and femoral (or thigh) shaft are still your own.
Refer to "What Is Hip Replacement?" Your Medical Source.
http://www.yourmedicalsource.com/library/totalhipreplacement/THR_whatis.html
This page will show you a diagram of what is removed and replaced in a
hip replacement. As you can see, although the "ball" is removed, the
artificial "ball" that fits into the socket of the pelvis is attached
to an artificial shaft that extends down into the femur.
The hip is a ball-and-socket joint comprised of the following
structures:
Head of the femur
Acetabulum of the pelvis
Ligaments of the hip joint
The head of the femur or "ball" of the hip joint articulates or moves
within the cup-like "socket" called the acetabulum of the pelvic bone.
Together, these structures are referred to as a "ball and socket"
joint. The femoral head and acetabulum are covered by a specialized
surface called articular cartilage. This allows smooth and painless
motion of the hip joint.

Also see "TOTAL HIP REPLACEMENT."
http://www.medfacts.com/d_tohip.htm
"A total hip replacement is a surgical procedure whereby the diseased
cartilage and bone of the hip joint is surgically replaced with
artificial materials. The normal hipjoint is a ball and socket joint.
The socket is a "cup-shaped" bone of the pelvis called the acetabulum.
*The ball is the head of the thigh bone (femur).
*Total hip joint replacement involves surgical removal of the diseased
ball and socket, and replacing them with a *** metal ball and stem ***
inserted into the femur bone and an artificial plastic cup socket.
*The metallic artificial ball and stem are referred to as the
"prosthesis."*
Upon inserting the prosthesis into the central core of the femur, it
is fixed with a bony cement called methylmethacrylate. Alternatively,
a"cementless" prosthesis is used which has microscopic pores that
allow bony in growth from the normal femur into the prosthesis stem.
This "cementless" hip is felt to have a longer duration and is
considered especially for younger patients."

If you did, in fact, have a "Hip resurfacing" then it is merely a
matter of miscommunication of surgical terms.
Please see the following reference and let me know if Hip resurfacing
is actually the surgery you are discussing!
http://www.joint-replacements.com/hip%20replacement.html
Hip resurfacing (Birmingham hip resurfacing; BHR)
"A relatively new kind of hip replacement in which the ball of the
femur is "resurfaced" with a metal shell rather than being removed and
replaced. This preserves more of the patient's own bone and produces
a more anatomical load bearing on the femur. (see X-Ray of the
Birmingham hip replacement in situ.) The socket is replaced as in a
traditional hip replacement procedure, without cement."

I hope this additional information helps. After you have reviewed the
diagrams concerning hip replacement, please let me know if it explains
your surgery more clearly. Did you actually have hip resurfacing? I am
curious to know!
