Alternatives for hip resurfacing

The era of the Biomet Recap/Magnum has come to an end. Zimmer has stopped manufacturing this implant. After nearly 20 years of using this implant for hip resurfacing and posting the best long-term durability outcomes for any type of hip surgery, I will have to change. To continue performing hip resurfacing for all patients is becoming more challenging because of Zimmer's unfortunate decision.

I will offer the BHR (Birmingham hip resurfacing) to men with good bone. Shorter men have a higher chance of needing a smaller implant (not available) and will sometimes get a backup total hip replacement (THR). Women and shorter men can choose to enroll in the Polymotion Hip Resurfacing study and receive this implant.

Certain patients with poor bone quality will no longer be candidates for hip resurfacing because both of the currently available implants feature cemented femoral components which have an excellent track record with good bone, but a higher failure rate in patients with osteoporosis or bone defects.

Other implants are in the development pipeline, but only limited options are currently available.

BHR versus Recap/Magnum In Metal-on-Metal Hip Resurfacing

4/4/2023

A recent serious supply chain problem has forced me to rethink my exclusive use of Zimmer-Biomet Recap/Magnum hip resurfacing implants. There are currently only three implants available in the US. Ceramic-ceramic trials are underway in Europe and Metal/polyethylene designs are on the drawing boards of several companies. These will likely take years to come to market.

Available implants:

  1. Zimmer-Biomet ReCap/Magnum (RM) metal-on-metal (MoM). FDA-approved implants used in an off-label fashion by me and others for hip resurfacing. Both components are porous for bone in growth. All sizes are available. No restrictions for women. Most data available is my personal data. A few other surgeons in the US use these occasionally. It is not available outside the US. I designed these but no longer receive royalties. I have been using this since 2007 and my data is published on my website as well as in peer-reviewed scientific journals.
  2. Smith-Nephew Birmingham Hip Resurfacing (BHR) MoM. FDA approved for the indication of hip resurfacing. Available worldwide. The femoral component is cemented, and the acetabular is porous for bone ingrowth. Most used resurfacing implant by far with extensive data from many centers supporting its use. Smaller sizes below 48mm have been withdrawn from the market. The label has been amended to exclude women.
  3. Synovo Preserve ceramicized metal/polyethylene boutique implant is only available to Jim Pritchett. Both components are porous for bone ingrowth. FDA status is not known to me. All sizes are available. No restrictions in women. All data is by Jim Pritchett
