Hip Recalls

As I’m sure many of you are aware, there have been a number of recalls of hip replacements, recently. The Zimmer Durom cup and the Stryker Trident ceramic system have both come under suspicion of causing problems. A number of my patients have been calling with concern about the hips that they have in place or are getting. I’ve been very fortunate in that I’ve never used either of these components. While it’s impossible to predict the future, I try very hard to use proven technology that has a long track record. Patients depend on us, as surgeons, to pick an implant that works the best for them, but will also last a long time. I take this issue very seriously and my philosophy is always to use the best implant available at any given time. I am always open to discussion about the actual parts being used. If something is going to be part of a patient’s body, they should be very well informed about it beforehand.

Birmingham Update

We’ve been using the Birmingham hip resurfacing for about a year now. I think that overall, it’s been a great success. The patients are very happy with their quick recovery and we’ve have very few problems. I believe that the most important key to success is picking the correct patients for the surgery. The ideal patients are younger, active, and have arthritis without a lot of deformity. It’s also important to examine the bone for cysts and other problems that might lead to early failure. For younger patients who don’t fit these criteria, they do extremely well with metal-on-metal total hip replacement.
I’m going to be attending a meeting in August that will focus on some future possibilities with resurfacing. Hopefully, I’ll be able to post a new update then.

Pain Control After Surgery

Controlling pain is one of the most important areas of postoperative care. It is usually the aspect of surgery that scares patients the most and is most ignored by doctors. We have tried to take a more comprehensive approach. The most important principle is to treat the pain with different modalities so that we have to use the least amount of narcotics. Narcotics are the drugs that make patients sleepy, constipated and unable to cooperate well with their physical therapy.
We use local blocks, spinal anesthesia and injections around the incision to help control pain. By combining these methods with nonsedating drugs, we are able to keep patients very comfortable and use very little sedation after surgery. The nurses who take care of our patients after surgery have seen a dramatic difference in the amount of pain that patients report to them after surgery. I see this as one of the most important aspects of our care and does more to ensure rapid recovery than any other method we employ. If you have any specific questions about the exact methods we use, please email me any time.

Tapered Titanium Stems

We've been using tapered titanium stems for total hip replacements for many years now. They fit into the thigh bone and require no cement. The bone grows into the roughened surface plasma sprayed onto the titanium to make the new part literally part of the natural bone. I recently wrote a short monograph, along with some other well know physicians, that was published in one of the orthopaedic trade journals. If you would like some more information, here is the link. My article is on pages 7-8.

Anterior Hip Replacement

Our anterior hip project continues to progress well. We are able to perform the hip replacement without using special tables or x-ray machines, which makes it quicker and easier to set up. There is also less uncertainty about the placement of the components when I can see them directly. Patients appear to have little to no pain, although, I'll have to collect more data to know for sure. Certainly, they are recovering their function and ability to walk very rapidly.

Birmingham Hip Resurfacing

We are now approved to do the Birmingham hip resurfacing at the Rubin Institute. I've done a lot of very similar surgery in the past, so this new prosthesis isn't much of a change. I had to go through training with the designer, Mr. Derek McMinn, from Birmingham, England, before we could get the prosthesis at our hospital. The big difference is that the Birmingham hip is FDA approved. The other hip resurfacings in the US are still being investigated and haven't been approved, mostly due to the lack of good long term data. We are very excited to have the ability to offer this option to our younger patients. If you want some more in depth information on hip resurfacing, take a look at SurfaceHippy, an independent site which had collected a lot of excellent information on hip resurfacing.
