Joseph M. Schwab (00:05):
On today's episode of the AHF podcast, we
have Dr.
Charles Lawrie, an orthopedicsurgeon at Baptist Health in
South Florida, and, thankfullyfor me, the vice president of
the Anterior Hip Foundation andan excellent partner in helping
run the AHF.

(00:25):
Charles, welcome.

Charles M. Lawrie (00:27):
Thanks, Joe.
Thanks for having me.
Good to see you this morning.

Joseph M. Schwab (00:29):
First of all, give me a little bit of
background about your, educationand training.
I think you did your fellowshipat Wash U, is that right?

Charles M. Lawrie (00:37):
Yeah that's right.
I'm originally from Houston,Texas.
I did my medical school there atBaylor college of medicine.
I did residency in Miami,Florida, university of Miami,
and then ended up in the Midwestat Washington university in St.
Louis, for fellowship.
had a fantastic year of trainingthere, where I really got my
bulk of my initial exposure toanterior approach.

(01:01):
and then I was lucky enough tobe invited to stay on as
faculty, which I did for a fewyears.
my wife and I couldn't toleratethe Midwest weather much longer.
after a couple of years there,we, headed back down to Miami,
Florida, which is where I'mcurrently in practice.

Joseph M. Schwab (01:16):
So tell me a little bit about your exposure
to answer your approach at WashU, because was it mostly with
Clohisy or who is it with?
And tell me a little bit aboutthat.

Charles M. Lawrie (01:26):
Yes, I guess I should back up a little bit.
I did get a little bit ofexposure, in residency at
University of Miami, with,Michaela Schneiderbauer, as well
as, Victor Hernandez, both ofwhom were doing predominantly
off table anterior approach hipson a standard OR table.
but the exposure is prettylimited, as a resident, you're
more seeing than doing, youdon't really get a flavor for

(01:49):
the real procedure in detail.
so in fellowship, like I said,it was when I really got my,
bulk of my initial exposure, andthat was through John Clohisy
and he does the procedure, on asplit pegboard and a lateral
position, similar to like howsomeone would do a Watson Jones,
ABMS type procedure.
but actually utilizing the, themodified Smith Peterson interval

(02:12):
that we use for direct anteriorapproach.
so that's how I came out offellowship training and started
doing them in my practice.
and I realized, although it was,a very good procedure, it was
very efficient to do it thatway.
I think I was feeling I wasmissing out on some of the
benefits of interior approach,which, in my opinion, are supine

(02:34):
positioning of the patient,reliable pelvic positioning in
that supine position.
Also, the supine positioning,allowing the use of fluoroscopy,
and all the wonderful tools thatlets us use.
and then, furthermore, the,traction table, of course, which
we all love.
so I started exploring ways to,transition out of that lateral

(02:55):
position into, the moremainstream, interior approach.
I tell people in trainingcourses that I teach at, I've
literally done anteriorapproach.
I think every single way you cando it.
I started in the lateralposition.
I started doing it off tablewith, without a hook.
I started doing it off tablewith one of those.
hooks you put on the table.

(03:15):
And then finally, I went to gosee someone do it on a Hana
table.
and it was just like, everythingclicked all of a sudden.
And I said, this is the way I'vegot to do it.
I convinced the hospital to buya table.

Joseph M. Schwab (03:26):
When you finally, obviously probably the
evolution of your, performinganterior approach hip
replacement is not done, right?
But when you went that dramaticchange from the lateral position
to the supine position, whatwould you say was the biggest
challenge that you encountered?
And what was the biggestadvantage that you encountered?

Charles M. Lawrie (03:47):
You know, the lateral position has its own
struggles and own benefits justlike doing any surgical
procedure.
In particular, the lateralposition was great for femoral
exposure because you can reallyget a great angle especially if
do a little bit of thehyperextension of the bed.
and it was like that on steroidswhen you were in the lateral

(04:08):
position.
Cause you could, you couldadduct the operative leg way
behind the other leg and thefemur would just pop right up.
Like I remember I'd go tomeetings and hear people talk
about, Oh, anterior approach,the femurs, the problem, the
femoral exposure is so hard.
I was thinking to myself, whatthe heck are these people
talking about?
like the femur is so easy froman anterior approach, but I

(04:28):
didn't really get it until Istarted doing the procedure, on
supine position on a regulartable or Hana table where I was
like, okay, you got to work justa little bit more to get that
exposure that I was used to.
the downside of that was it.
Because you're adducting it sohard.
I felt like the tensor maybetook a little bit more of a
beating, because you were reallyretracting hard on that muscle

(04:49):
belly.
so I did notice that when Iswitched to a supine position,
the tensor usually looked alittle bit prettier, more
pristine at the end of theapproach,

Joseph M. Schwab (04:57):
And do you think the way you approached it
from a supine position wasaffected by what you learned
while, while doing it in thelateral position?

Charles M. Lawrie (05:06):
just learning the anatomy.
the basics of the approach, howto actually get down to the hip,
anatomy of capsule releases.
all of that foundation wasinstilled in me by Dr.
Clohisy during my training.
So I was able to take that andtranslate it, into that more
traditional way we do things.
Now.
I just had to turn my headsideways for a couple of months

(05:28):
while I was looking at things.

Joseph M. Schwab (05:29):
I'm sure that was, had its own brand of
disorientation to it.
So now you're down in Miami,you're doing a primarily a total
joints practice down there.
Is that correct?
Hips and knees.
Yes.

Charles M. Lawrie (05:40):
Yeah.
I'm about 50, 50, total hip,total

Joseph M. Schwab (05:43):
Okay.
And primary and revision or,mostly sticking to primaries.
How does that shake out in yourpractice?

Charles M. Lawrie (05:50):
I'm about a 15 percent revision.
that's mostly what I call itkind of bread and butter type
provisions, headliner exchangesfor wear loose cups.
occasionally a loose subsidedstem, we're really just not
seeing, massive, revisions likewe used to.
And I think that's been borneout in a couple of papers that

(06:10):
have been published recently aswell.

Joseph M. Schwab (06:12):
Yeah.
And so tell me how you got endedup getting connected with the
Anterior Hip Foundation orwhat's your journey there.

Charles M. Lawrie (06:19):
Sure.
I've been passionate aboutanterior approach, really since
I learned it.
the first time I saw it, therewas this aha moment at the end
of the procedure where, you takeall the retractors out and the
tensor muscle belly falls backwhere it should be.
And the skin closes togethernicely, and it just felt so much

(06:40):
more anatomic and so much lessinvasive as a surgeon, that a
posterior approach did.
So I knew that was going to bemy approach moving forward.
and then when I was at WashU inpractice, going through my
learning curve, once I was outof fellowship.
I was still doing a little bitof posterior approach, still
doing, some anterior approach.

(07:00):
And my nurse one day came up tome and said, Dr.
Lawrie why are you still doingposterior approach?
Those patients just don't do aswell.
So at that point I said, this isit, I have to do anterior
approach.
and I committed myself to it.
and once I, we're in theapproach, I was comfortable with
just some meetings, with theanterior hip foundation once, I

(07:21):
said, I think I want to be moreinvolved in this.
it's been such a gift to be inmy patients.
I really want to get back, andteach and train.
So lucky enough, I've been ableto do that through industry,
teaching some courses throughthem, which is where I met
Jonathan Yerasimides, who wedeveloped a, a close
relationship.
we teach at the coursestogether, hang out afterwards.

(07:41):
And I know he was very involvedin Anterior Hip Foundation
president last year.
so I was lucky enough that heinvited me to get involved,
through his involvement in theorganization.

Joseph M. Schwab (07:50):
And so this year you've got the role of vice
president and tell me a littlebit about what that includes and
what projects you're working on.
And what areas you focus on.

Charles M. Lawrie (07:59):
Sure.
So the vice president role, Iguess I should back up, this is
the, first year, and I want tothank you for doing this and we
have, more official officertitles.
I think in the past, it's been alittle bit more of a, smaller
group.
I don't want to call it rag tag,a smaller group of, of misfits

(08:23):
perhaps.
that, all had their individualroles and responsibilities,
maybe that were, not clearlydelineated, self understood, but
now, thanks to you, we'reshaping up to be more of a big
organization, which isappropriate as we've grown so
much.
so the vice president role,really spun out of being, the,

(08:45):
lab chief for the manager of thelab, which Tania Ferguson was
last year.
So my primary role in theorganization is organizing and
coordinating the cadaver labcomponent of the annual meeting,
which, of course, we know howimportant hands on training is
when you're learning a surgicalapproach.

(09:05):
But in addition to that, I seemyself as well as the education
chief.
coordinating the educationalprogram with you developing an
educational curriculum, thatwe're going to have the lab
attendees do before the meeting,and taking that 1 step further
and hopefully developing.
some great online contentaccessible to all surgeons that

(09:29):
they can use either to learnanterior approach, or to hone
their skills on more advancedtopics that we choose to cover.

Joseph M. Schwab (09:36):
And so the lab portion of the AHF, which has
been around for a few years,primarily focuses on, early
learners, right?
Residents and fellows.
tell me a little bit about howthat makes, the AHF lab, maybe
different than what you've seenelsewhere or, how that adds

(09:59):
value from your perspective.

Charles M. Lawrie (10:01):
So a lot of labs that you go to, training
courses, conferences.
They just lump everyone togetherwhen they go to the cadaver lab,
you have everyone from, secondyear residents all the way
through surgeons who are end ofcareer trying to learn something
new.
and I think the learning needsfor each of those different
groups are completely different,right?

(10:22):
someone who is a veryexperienced surgeon, maybe even
has some experience workingaround the hip and the pelvis.
learning anterior approach isgoing to need a little bit
different handholding throughthe lab than someone who's in
training and has been exposed toa lot of anterior approach but
hasn't really gotten the handson practice.
So I think segregating thosegroups out when we're actually

(10:46):
going to the lab and teaching,is important and it really helps
us as the faculty do a betterjob of shaping the lab to meet
the needs of each of thosegroups.
if you look at Anterior HipFoundation lab, we've chosen to
have a Thursday lab, which ispre course, pre main didactic

(11:06):
program that's only available toresidents and fellows.
and what that allows us to doagain is really shape that
content, shape the curriculumfor the lab, as well as the
experience toward thoselearners.
on top of that, I think, assurgeons, we all learn from each
other, and that starts early onand residency and fellowship.

(11:28):
So it was really rewarding.
last year, I remember.
You walk into the lab, we had aton of AHF faculty in there, but
the real teaching and learningwas happening from, chief
resident to third or fourth yearresident or fellow from one
program telling a fellow fromanother program, Hey, we do it
this way.
Try that.
so it was really just nice tosee that cross pollination of

(11:50):
ideas already happening.
At that level, I think in a waythat you wouldn't see if you
had, second year residents atthe same table as a, guy in the
60s, who's been doing this for20 years, trying to learn a new
approach.

Joseph M. Schwab (12:05):
and tell me a little bit about how, how that
lab works with industry toprovide a good experience.

Charles M. Lawrie (12:15):
So we truly couldn't do it without our
industry partners.
so this past year, we were luckyenough to have Zimmer Biomet as
our Thursday lab sponsor.
and we call them the Thursdaylab sponsor, but they're really
so much more than that to us.
they sponsor the travel, theysponsor the registration fee.
They basically sponsor,attendance at the whole meeting

(12:37):
for the residents and fellowsthat are going to attend that
Thursday lab.
and beyond that, they reallyallow us to have the freedom to
shape that lab, to be what wewant.
you go to most industry courses,the industry is in charge of
curriculum..
some of those labs can come off,a little bit more sales forward,

(12:58):
trying to get you to use theirproduct, of course, which is
appropriate in that settingbecause they're putting the lab
on.
at Anterior Hip Foundation theyunderstand our goal is truly
education.
So they sponsor, the travel,they sponsor the meeting
attendance.
They bring all their implantsand instruments, and they really
just take a step back and say,Hey, you guys go have fun in the
lab.

(13:19):
we're going to let you do yourthing, and we're just going to
be here to help you out, whichhas been wonderful.

Joseph M. Schwab (13:24):
If you had a wish list for the AHF over the
next couple of years, two,three, five years, what would be
on that list?
Give me a couple of things.
Okay.

Charles M. Lawrie (13:35):
I think number one would be, truly
becoming the F of AHF, right?
right now, Anterior HipFoundation.
To the outside world isbasically a meeting that we put
on once a year, right?
I would love to see that growinto more of a year round
organization, similar to Academyor AAHKS where we have

(14:01):
membership in the organization,that would create a real sense
of community around anteriorapproach surgery, not just at
this meeting.
it would allow us to developthat online educational content
that people would have accessto.
potentially webinars and thingsthroughout the year.
that would be number one on mylist is becoming, the Anterior

(14:22):
Hip Foundation as a true yearround organization that people
could interact with, and havemultiple events throughout the
year.
the second one, selfishly, Iknow you're, based over in
Switzerland now.
So it would be wonderful for usto develop a little bit more of
a international presence.
and I think it'd be great to dothat through having, meetings,

(14:44):
maybe in Europe every otheryear, whether that would be an
augment to, or in place of theAnterior Hip Foundation meeting
in the U S, to be determined.
But, I would love to come overto Switzerland and have more of
a European influence because,seeing, European surgeons do
anterior approach is totallydifferent than surgeons in the U
S I know you guys are more offtable, you're less, fluoroscopy

(15:08):
based, but, certain aspects ofthe approach are different.
Some of the implants aredifferent.
So really having the twodifferent ideological camps
meeting together in one place.
I think it would be really coolto see, and I guess number
three, no one's discussed the,the organizational structure,
and how, succession plans go.

(15:30):
But of course, being vicepresident.
two year term here.
I'm hoping that, two years fromnow I get the promotion to be
the big president, we'll see

Joseph M. Schwab (15:41):
Charles, this has been great.
I really appreciate theopportunity to talk with you and
have you, Share some of yourthoughts with us, especially
about, your involvement with theAnterior Hip Foundation, where
you'd like to see it go and,what we can expect for 2025.
This has been great.
Thanks for joining me.

Charles M. Lawrie (15:59):
Yeah.
Thanks Joe.
Really exciting to see, what'scoming in 2025.
I hope to see everyone at thebig meeting this year.

Joseph M. Schwab (16:06):
thank you for joining me for another episode
