Modern hip replacement

Ceramic hip resurfacing – bone-preserving and metal-free

With ceramic hip resurfacing (often called a cap prosthesis), only the worn surface of the femoral head is replaced rather than the entire head. The femoral head and neck are preserved. Unlike older metal resurfacing prostheses, the cap and socket are made entirely of ceramic. At our clinic at University Medicine Greifswald, we perform ceramic hip resurfacing through the anterior, muscle-sparing approach.

What is hip resurfacing?

With a conventional hip replacement, the femoral head is removed and a stem is inserted into the thigh bone. With hip resurfacing, the femoral head is shaped just enough for a cap to fit over it. A matching socket is placed in the pelvis. This largely preserves your own thigh bone.

Why ceramic?

The first resurfacing prostheses were made of metal. Wear could release metal ions, potentially causing problems in the tissue. With ceramic hip resurfacing, ceramic glides on ceramic. No metal ions are released from the bearing, and ceramic has very low wear.

Who is suitable for ceramic hip resurfacing?

Ceramic hip resurfacing is particularly suitable for active patients with hip osteoarthritis who want to preserve as much bone as possible and return to sporting activity. Smaller hips, for example in women, and many deformities of the hip joint, such as those following hip dysplasia, are no longer necessarily an obstacle.

The shape and bone quality of the femoral head are decisive. We assess your X-rays to determine whether resurfacing is possible for you. If it is not, we offer a bone-preserving short-stem prosthesis through the same gentle approach.

The advantages at a glance

  • Bone-preserving: the femoral head and neck are preserved
  • Metal-free bearing: ceramic on ceramic, with no metal ions from the joint
  • Natural biomechanics: your own head size and leg length are largely preserved
  • Large head, high stability: a low risk of joint dislocation
  • A good starting point for the future: if replacement is needed many years later, the full bone stock is still available

How the operation proceeds

We perform ceramic hip resurfacing through the anterior approach. We work through a natural gap between the muscles without detaching them. The operation takes approximately 60 to 90 minutes.

  • Hospital stay: 3 to 5 days
  • Standing up: usually on the day of the operation
  • Aftercare: we determine weight-bearing and movement permissions individually and discuss them with you before the operation

Frequently asked questions about ceramic hip resurfacing

What is the difference between hip resurfacing and a conventional hip replacement?
With a conventional hip replacement, the femoral head is removed and a stem is inserted into the thigh bone. With hip resurfacing, the femoral head is preserved and only its surface is replaced with a ceramic cap.
Is this the same as the earlier metal cap prosthesis?
No. Earlier cap prostheses were metal-on-metal. With ceramic hip resurfacing, the cap and socket are made of ceramic, and no metal ions are released from the joint.
Am I suitable as a petite woman?
Yes, in many cases. Smaller hips are no longer a general obstacle to ceramic hip resurfacing.
Is it possible after hip dysplasia?
Frequently, yes. Many deformities of the hip joint can be treated with resurfacing. We assess this using your X-rays.
Can I play sport again after hip resurfacing?
The aim is an active life. We discuss which sports and when you can resume them on an individual basis.
How long does the operation take?
Approximately 60 to 90 minutes.
How long will I be in hospital?
Usually 3 to 5 days.
Which approach is used?
The anterior approach. It passes through a natural gap between the muscles without detaching them.
What happens if hip resurfacing is not possible for me?
We offer you a bone-preserving short-stem prosthesis through the same anterior approach.
Which documents do I need for an assessment?
A current standing pelvic overview X-ray and an axial image of the hip. You are welcome to email me your images and findings in advance.
