Anterior Approach to Surgery by Dr. Matta

Hip Resurfacing at Surface Hippy Posted on by

 Note by Patricia Walter:  Sometimes hip resurfacing surgeons are not specific when they are talking about the “anterior approach to surgery” since this can include the Direct Anterior Approach, the Anterolateral Approach and other variations.  The surgeons using the posterior approach often refer to the “anterior approach” incorrectly to include all types of anterior approaches. Dr. Matta has written a comprehensive explanation of the Anterior Approach to explain the misinformation often presented.

The postings on your web site by some hip resurfacing surgeons is unfortunately giving false information about the Posterior vs Anterior approach. They are referring to the Anterior Approach in relation to what is now termed lateral approach through which the abductor tendons (gluteus medius and gluteus minimus muscles) are partially severed

Computer Navigation Discussion by Dr. Brooks

Hip Resurfacing at Surface Hippy Posted on by

Hi Pat,

Computerized navigation has been around for a long time, in
total hips, total knees, and now hip resurfacing. A lot of
surgeons, including me, have tried it out and not seen an
advantage in all but very exceptional cases. Yet other
surgeons use it on every case.

This is what I think about computerized navigation: It is a
tool which can narrow the “bell-curve” of component
position, but the curve still has some spread. That helps a
surgeon avoid “outliers”, or badly misplaced components.
Navigation does not make component position the exact same
every time, but it helps avoid those outliers. (If it was
the exact same every time there would be no bell-curve at
all.)

So, if a surgeon has no outliers,

Background: Recently, metal-on-metal hip resurfacing has
enjoyed a resurgence as an alternative to hip
arthroplasty in properly selected patients. The
purpose of the present study was to report the
early results of hip resurfacing through an anterolateral
approach and to describe the technique with
modifications that have been made as experience
with the procedure has increased…

…Conclusions: The early results associated with a
new generation of hip resurfacing devices are
promising. The anterolateral approach affords the
surgeon excellent exposure with the advantage of
increased hip stability and potentially improved … Read the rest

Neck Capsule Preservation NCP Approach in Hip Resurfacing by Dr. Su and Dr. Bose

Hip Resurfacing at Surface Hippy Posted on by
Obtained by Freelance Patient Advocate Volunteer Vicky Marlow 8/22/08

Dr. Su’s Article

The NCP approach, at least the way that we mean it, is a different
way to incise the capsule in order to gain access to the hip joint.
Usually with THR, the capsule is detached from the femoral neck and
flipped back. It is usually preserved and repaired in order to avoid
dislocation.

With the NCP approach in hip resurfacing, we cut the capsule along the femoral head, so
the capsule along the neck is not disturbed. This preservation of the
neck capsule should help preserve important blood vessels along the
femoral neck, which may in turn preserve blood supply for the femoral
head. This will hopefully improve longevity of the resurfacing.

Surgical Approach by Joint Replacement Institute of Los Angeles, CA

Hip Resurfacing at Surface Hippy Posted on by

What are the differences between the posterior and anterior surgical approaches?

Recovery is quicker with the posterior approach because no
important muscle groups are sectioned. The posterior
approach is also well-suited for patients who are large,
well muscled or who require special techniques to implant
the hip resurfacing socket.

To improve stability and reduce the incidence of dislocation
after THR, some surgeons changed from the posterior to the
anterior approach. Even a hip resurfacing procedure
technically can be performed in most individuals using an
anterior approach but this requires removal of 33% to 50% of
the abductor muscles. Even though the muscle group is
reattached, the muscles are strong and, therefore, the
reattachment may pull loose even if activities are
restricted for a prolonged period.

Minimally Invasive Approach to Hip Resurfacing Surgery Dr. Bose 2008

Hip Resurfacing at Surface Hippy Posted on by

5/1/08

Yes, it is true that minimally invasive approach has been proven not to have great benefits over a conventional incision in terms of blood loss, pain , or speed of recovery in the same surgeons hands. It is only of cosmetic value.

All studies to investigate this have been done on two groups of patients in which a single surgeon employs the two approaches in the diff groups. When a surgeon who is capable of doing a minimally invasive approach does a conventional approach it is logical that the conventional technique will be only marginally bigger and therefore advantages do not show up in studies. However, if a minimally invasive approach of a surgeon is compared with a conventional approach of another surgeon who

Will My Neck Capsule Be Preserved?

Hip Resurfacing at Surface Hippy Posted on by

Dr. Bose

The NCP (Neck Capsule Preserving) Approach which is increasingly being adopted by surgeons world wide was developed at ARCH by Dr. Bose. This facilitates a faster recovery due to the repair of the capsule.  The vascularity of the critical regions of the head and neck is also preserved in the NCP Approach.

Dr. De Smet

Do you preserve the hip capsule during your hip resurfacing surgeries?

[Koen De Smet ANSWER/]  YES AND I THINK YOU SHOULD

Dr. Rubinstein

Saving the capsule is good with a THR because it may decrease the rate of dislocation. In regular THR it can go either way saving or not. Due to the technical needs of the resurf procedure the
capsule must be fully opened and partially removed. … Read the rest

Approaches in hip resurfacing by Dr. Gross

The path that surgeons choose to arrive at the hip joint is called the
“approach”. There are many different basic approaches used for hip resurfacing.
None has been proven to be superior to others based on valid scientific
research. Basically, I recommend that a surgeon use the method that he/she is
already most comfortable with when performing standard total hip replacement and
modify it as needed for the more complex hip resurfacing operation. My preferred
approach is the posterior. This is used in at least 70% of hip resurfacings done
worldwide. The next most common approach is the lateral (two versions:
anterior-lateral and direct-lateral). Finally the direct anterior and the Ganz
(or trochanteric, or internal dislocation) approach are … Read the rest

Posterior Approach by Dr. Bose

Hip Resurfacing at Surface Hippy Posted on by
The post approach which I employ is traditionally known as the muscle sparing approach and the anterior and anterolateral approaches which is very popular in the U.S and some parts of Europe are the muscle compromising approaches. The muscle here refers to the Abductor group or the muscles which lift your leg sideways and is the most important muscle of the hip. The post approach spares this completely.However some muscle have to be cut in any approach to get access to the hip and in the post approach, one cuts the short ext rotators which are flimsy , small muscles in the back of the hip. These  are stitched back. These muscles are relatively unimportant as the main ext rotator is the gluteus maximus which

Anterolateral Approach to Surgery by Dr. Mont

Hip Resurfacing at Surface Hippy Posted on by

The choice of approach to use for resurfacing has received much attention and I believe extra “hype.” In multiple studies now published, there are no reported clinical differences in the short term and up to ten years of follow-up between anterior and posterior approaches. I believe that any approach can be used and the surgeon should use what they feel most comfortable.

Short-term differences that patients may report with either approach have to do with other factors in my opinion. I use the antero-lateral approach because it affords me easy exposure, lower dislocation risk, less chance to disrupt the blood supply of the femoral head
– among other reasons. However, I have no problem with posterior approaches and am currently working on an even more … Read the rest

Computer Navigation Discussion by Dr. Schmalzried

Hip Resurfacing at Surface Hippy Posted on by

Dear Pat,

There is some data indicating that navigation can improve
the accuracy of femoral component placement in hip
resurfacing.  The real issue is “compared to what?”  For an
inexperienced surgeon, navigation may help him avoid
component positioning problems that have been associated
with “the learning curve”.  However, for an experienced
surgeon, who has an established mechanical alignment system
with a high success rate – it is difficult to demonstrate an
advantage to him with a navigation system.  Further, the
registration process takes a little time – so the
cost-to-benefit ratio for the experienced surgeon in a busy O.R. is questionable.  The navigation systems are not hard
to learn to use, even for old guys like me!

A bigger challenge is acetabular component positioning.

Surgical Approaches for Hip Resurfacing by Dr. Su

What Surgical Approach do you Use?

I like the posterior approach for the excellent exposure that it provides (which is critical for the positioning of the implants) and the ease of recovery for the patient. There are some who believe a trochanteric flip (Ganz osteotomy) or anterolateral approach are better for the blood supply, but we saw from Mr. Treacy’s data that there wasn’t any difference in outcomes between the posterior and anterolateral approaches. Also, the recovery from the anterolateral and trochanteric flip tend to be more difficult, with protected weight bearing and avoidance of certain movements. Finally, if the muscles that were detached during the anterolateral approach don’t heal back to the bone, then this can be a serious problem. I don’t have much

Computer Navigation Discussion By Dr. Gross

Hip Resurfacing at Surface Hippy Posted on by

Dear Pat,

Thank you for the work you do, it helps so many.

Computer aided navigation is an
interesting concept. However, there is no evidence that it
leads to better clinical outcomes and fewer failures. On the
other hand, there is ample evidence that surgeon experience
has a dramatic effect on outcomes and complications.

One way to conceptulize this is that the experienced
surgeon’s brain is a computer with much more sophisticated
“software” than a navigation computer. When a computer is
programmed, an algorithm must be created which has certain
inherent limitations. Furthermore additional significant
sources of errors are introduced by the registration of
anatomic points for the navigation computer in surgery.

My personal opinion is that navigation that is based on a
pre-operative CT

DEAR PAT

WHAT ABOUT NAVIGATION

Today navigation is still a tool that is not easy to use and
that needs a certain learning curve as resurfacing itself
also has.

So it is not a useful tool today for resurfacing beginners,
where it should be! It would be nice if it would be a help
at the start of the learning curve.

So can somebody with experience use it or should they use
it?

It is like doing a certain approach and having experience
with it, so it feels better and confident.

Most of the experienced surgeons do feel they do not need
it. MAYBE it could help.

BUT there are some things that have to be cleared out still
today:
