Hip Replacement
Dual Pivot Hip
Jan,13,2012 16:39
I’ve mentioned metal on metal hips a few times in past posts, and as many people are aware, there has been a great deal of concern about the long term effects of this type of hip. While I am convinced that only a few of these designs are a problem, it’s important to understand the benefits and if there are any other ways to achieve the same results. Recently, we have had great success using a dual pivot design for hip replacement. This design provides all the benefits of metal on metal - the large head and wear resistance - without an actual metal on metal surface. The dual pivot design employs a smaller ceramic head, embedded into a large plastic head that is placed into the same socket we used for metal on metal. The plastic is very thick and wear resistant and the dual pivoting surfaces should result in less wear over time.
For younger patients who have concerns about metal on metal and need the range of motion and durability, I think this represents a great option.

Corin Minihip

The anterior approach can have advantages for early recovery. Many patients are able to go home in one to two days. However, it often requires a complex table or forceful manipulation of the leg during surgery. The Corin Minihip allows us to preserve bone and perform anterior surgery much more easily due to it’s shape and small size. it has been an excellent alternative to resurfacing in patients who want to preserve bone, have a mini incision, and have a full active lifestyle.

Trip to Italy
Jun,28,2010 20:45
I recently had the incredible opportunity to travel to Italy and operate with a number of surgeons who perform hip revision surgery. I was helping DJO Surgical evaluate a revision hip made by Lima - an italian company that has created some very impressive technology to deal with difficult revision surgery. I learned a lot of interesting techniques and got to eat some incredible food. Hopefully, we will be able to import some of these innovative implants to help patients here in the states.

German Surgeon Visit

We often have visitiors from around the world at the Rubin Institure. Recently, I had a group visit from Germany to observe hip and knee replacement. They were very interested in minimally invasive surgery and pain management techniques. They also got to see a minimally invasive hip replacement, revision knee replacement and a hip resurfacing. I always have a great time showing off what we are able to accomplish at the Rubin Institure, but I also get to learn a lot myself. Out visitors never fail to teach me some technique I wasn't aware of or propose some improvement we can make. it's this kind of interaction that forces me to always try to stay ahead of our very knowledgable and experienced visitors.
Hip Recalls
Sep,25,2008 08:21
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.
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.
