This is a transcript of a Live Chat in the Surface Hippy Chat Room with Dr. Rogerson on February 9, 2009
[Pat Walter Moderator] 8:07 pm: Hello Dr. Rogerson
[Dr. Rogerson] 8:08 pm: Hi Pat
[Pat Walter Moderator] 8:08
pm: Thanks for taking time to chat with us.
[hipster58] 8:09 pm: I’ve been told that SOCKET POSITION IS most
important, so I’m going to ask my Surgeon “how he will verify the position of
the socket”. So my question to you is, what is the correct method of
determining the precise optimal socket position?
[Dr. Rogerson] 8:10 pm: the best way is to know
the landmarks and use x-ray if any concerns
[gratefulgee] 8:10 pm: I have OA in both right knee and hip. All other things being
equal, any thoughts on which one knee or hip should be done first. I’m
thinking of resurfacing for hip.
[Dr. Rogerson] 8:11 pm: Hip first because a lot of knee pain can be
referred from the hip
 8:11 pm: Why are
there so many different recovery protocols between surgeons?
It can become confusing as we compare activities and
[Dr. Rogerson] 8:13 pm: Different
protocols based on different philosophies and degree of risk a surgeon is inclined
[obxpelican] 8:11 pm: How long do
your patients usually take heavy pain meds post-op?
[Dr. Rogerson] 8:12 pm: 2-3 days for narcotics and then Tylenol
after that usually
[Ted] 8:12 pm:
Regarding age limitations. I’m a very active OB-Gyn whose tennis has been
compromised by hip pain. Bones are excellent by Dexa. Great longevity in family.
We have a surgeon in Rochester who has performed > 200 and according to the rep
one of the best. would I be a candidate for this op and is this experience
[Dr. Rogerson] 8:13 pm: My oldest patient was 81 and he is still
playing high impact sports
I woke up from my
resurfacing procedure to find a 14″ scar, with an explanation that I was “very
muscular and tight, and they needed more room to move things out of the way in
order to do the procedure.”
[Dr. Rogerson] 8:14
pm: Better to make a longer scar and do the operation correctly than struggle
with tight muscles and get the position wrong
My recovery has been normal when compared to
most accounts I have read, i.e., off pain meds at about 2 ½ weeks, walking
without a cane at
 8:13 pm: hi doc.I’m 46 had back surgery
1990, played basketball all my life, even after my back surgery. Now my hip can’t
move. Had x-rays and MRI but I became an insulin dependent diabetic and have
retinopathy. would you still go ahead with the surgery?
[Dr. Rogerson] 8:15 pm: if bone density is
ok with diabetes and kidney function is excellent, one could proceed with
 8:16 pm: what about fatty liver
Rogerson] 8:21 pm: fatty liver would
be a concern
[Dr. Rogerson] 8:14 pm:
insurance will usually not pay
 8:14 pm: Why would such a large incision be used and what
affect would it have on rehab?
[Dr. Rogerson] 8:17
pm: One has to make the incision long enough to move the head anteriorly. In
heavy or very muscular patients it can sometimes take that much.
[Dr. Rogerson] 8:17 pm: De Smet uses a long incision on
[hipster58] 8:14 pm: Socket
Positioning. So it’s all experience, there are no Hi Tech devices for alignment?
[Dr. Rogerson] 8:18 pm: x-rays during
surgery are some times necessary. Computer navigation is just being
8:19 pm: Computer Navigation also requires pins into the pelvis which can cause pain and possible
[hipster58] 8:16 pm: For resurfacing, do you
prefer any specific manufacturer’s prosthesis?
[Dr. Rogerson] 8:20 pm: I use BHR but the Cormet has also been FDA
 8:18 pm: What other issues would result
in a patient requiring narcotic medication (oxicodone) for two weeks vs those
who only need it for 3 days post op?
[Dr. Rogerson] 8:20 pm:
I usually don’t find the length of the incision correlating with the pain that
closely but more the swelling and bruising after the operation
Rogerson] 8:22 pm: swelling and rehab
program and pain threshold
[Dr. Rogerson] 8:21 pm: would want to check the kidneys
[jimbo] 8:19 pm: How long post
surgery can one be relatively certain (or at least less fearful) of hip
dislocation due to immature healing of the muscles and tendons that were cut to
reach the resurfacing site.
[Dr. Rogerson] 8:22 pm:
one should be careful for the first 8-10 weeks on the position of the hip so as
not to dislocate
 8:21 pm: In recovering in the
weeks after surgery, what is typically the most difficult muscle and function to
return to normal? Is it more effective to improve ROM or strengthening to help
recovery? My lateral stability is what seems to be difficult to get back. Is the
capsule slow to heal, or certain muscles around it?
[Dr. Rogerson] 8:23 pm: hip flexion
lying down is the slowest
[Dr. Rogerson] 8:24 pm: lateral strength
usually comes back if the abductor is not injured
pm: Hey Dr Rogerson, Spencer in Tucson here. Just a testimonial on what’s
possible from this surgery which you performed 6/26-08. I am back to running and
lifting regularly. Just ran a 6:30 mile and squatted 215lbs. Just wanted to say
[Dr. Rogerson] 8:25 pm: Great
[hipster58] 8:24 pm: BHR I’m afraid not of hip pain
after surgery…but my lower back MR looks relatively good, but spine can
shift when I’m bending down w heavy loads and pulls my back out. I get
excruciating pain can’t move my lower extremities, and need to yoga out stretch
and breath to return to normal. During my first colon exam my back when out, and
took a day or two to recover.. I think it was the relaxing drugs they used that
made the spine slip……ie may you suggest a operation anasthesia
8:26 pm: often the strain on the back is relieved after resurfacing to a large
degree because the range of motion of the hip is so much
[Dr. Rogerson] 8:26 pm: would want complete muscle relaxation at the
time of surgery for the back
[dvander@wilsonchristian.,] 8:26 pm: I can
testify to that. My back strain is nearly gone!!!
pm: Are metal ion issues any way a greater concern for otherwise healthy females
in their early 50’s than males?
[Dr. Rogerson] 8:27 pm:
no difference vs male and female at 50
 8:26 pm:
what can one do if they are not candidate for BHR or THR, be it diabetic kidneys
and or fatty livers etc.
8:27 pm: would go with traditional hip metal on plastic if bad kidneys and
 8:28 pm: Can you do both hips at the same time or do you
recommend a time for rehab between when both need done?
[Dr. Rogerson] 8:29
pm: I put 2-3 months in between. One of the complications reported was femoral
neck fracture of the first hip when the socket for the second was impacted on the
 8:29 pm: In 20 years when my first BHR finally wears out, can I
expect medical advancements to allow me another? I’d like to play basketball in
the Octonarian League someday.
[Dr. Rogerson] 8:30 pm: yes Mr. McMinn is perfecting a “midhead”
which may allow continued high activity
[hipster58] 8:29 pm: So about back going out, then no
particular anesthesia may be better at preventing this?
[Dr. Rogerson] 8:31 pm: general with
complete muscle relaxation would be best for back
8:30 pm: I will be 11 weeks post surgery tomorrow and my operated hip still
feels weak if I try to go up stairs without using the handrail. Is this normal
or should I be bouncing up the stairs by now?
[Dr. Rogerson] 8:32 pm: a little slow on the stairs but if still
improving would just keep on being active and go back into PT for
8:30 pm: at 46 years old to have a THR and even a BHR, will I need to have a
second THR at some point in my life?
[Dr. Rogerson] 8:34 pm: no one can say for sure how long you will
get out of any type of joint, but there is more ease of reversibility with BHR
than regular total hip replacement
 8:31 pm: Does Smith & Nephew make a corresponding THR spike
and ball that could be used in a revision of a BHR that would be compatible with
an existing and otherwise solid BHR cup?
[Dr. Rogerson] 8:32 pm: Yes on the Smith & Nephew stem
 8:34 pm: I’m 8 weeks post-op
and walking up to 2 miles at a time. I still have a achy tightness right on top
of the hip that just doesn’t seem to be getting any better yet. How long can
I expect to go before that disappears, or does it ever disappear
[Dr. Rogerson] 8:35 pm: It will disappear, but
the time can vary. Keep massaging the area and get in the pool to loosen it
[bgletizia] 8:36 pm: I am 54
and have OA in my right hip. I have already had a THR on my left hip in 1996 and
want to go ahead with a hip resurfacing on my right hip (can’t take the pain any
more and the limited ROM). My question is that there seems to be some differing
views on cemented versus uncemented fixation of the femoral component used in
hip resurfacing. I know that the majority of devices out there use cemented
fixation. Do you think there is an advantage of one over the
[Dr. Rogerson] 8:39
pm: the issue of cement vs non cement is hot right now. In my experience there
are a lot of hips that would not do well without cement because of the deformity
and differing density of the head. Right now the only FDA approved hips are
cemented and the track record for the uncemented is very short
[obxpelican] 8:36 pm: How long before you
allow frog kicks in the pool?
[Dr. Rogerson] 8:39 pm: 8-12 weeks on vigorous frog
[hipster58] 8:37 pm:
when can I drive after my BHR
[Dr. Rogerson] 8:40 pm: if left hip, one can
drive in 1-2 weeks, for right when one can walk without the use of
 8:38 pm: How much
hip pain during these first weeks after surgery comes from scar tissue, and is
massage on the hip the most effective way to help this, or does massage just
promote blood flow to that area?
[Dr. Rogerson] 8:42 pm: massage loosens scar and promotes flow. Pain
in the first few weeks is usually mostly swelling and bruising then becomes
scar at about 2-3 weeks
 8:40 pm: Is there
any scientific evidence that donating blood regularly can help reduce metal ion
build up in your system?
[Dr. Rogerson] 8:44 pm: no scientific evidence that I know of but
does make some sense.
[B.I.L.L.] 8:42 pm: I had a right BHR 9-22-08, in
January of this year. They
deemed it a failure due to a cup angle of 65 degrees. At a little over 4 months
I have clicking and knocking followed by a burning pain in the thigh and a
numbness throughout the whole hip area. A revision is scheduled in march. Have
you done cup revisions and kept the re-surfacing ?
[Dr. Rogerson] 8:44 pm: I have not personally had to revise a cup in bad position
yet but if the bone of the pelvis is thick enough it should be
[hipster58] 8:45 pm: How long
before I can drive my kids to school after BHR?
[Dr. Rogerson] 8:46 pm: depends on which hip as above, but 1-2 weeks
for the left and when off crutches for the right (usually 2-4
[Bionic] 8:45 pm: Which muscles do you
generally cut during the typical surgery
[Dr. Rogerson] 8:48 pm: Split the gluteus fibers longitudinally and
release and repair the upper 1/2 of the tendon. Release and repair the piriformis tendon and the short external rotators
[Ted] 8:47 pm: Do
you prefer spinal or epidural anesthesia vs general? Does general enhance the
exposure or is it more dependent on body habitus?
[Dr. Rogerson] 8:48 pm: I prefer general because
one can get better muscle relaxation and control the blood pressure
[chillman] 8:48 pm: Do you feel there is a benefit to perusing arthroscopic surgery for bone spurs and torn
cartilage? I realize that
there may be issues that are not necessarily visible with x-ray/MRI that might
make one or the other a better choice if all of the variable were apparently
[Dr. Rogerson] 8:50 pm: if there is not too
much degenerative arthritis in the hip then arthroscopic is helpful, but if the arthritis is
moderately severe the results with scope have not been impressive and would just
proceed with resurfacing
[Pat Walter Moderator] 8:51 pm: Have you had
any firemen, policemen or service men get resurfacing and then return to full
[Dr. Rogerson] 8:52 pm: yes for fire and
policemen but have not operated on any servicemen yet
Rogerson] 8:54 pm: patients are getting
back to their previous recreations and occupations without
[Pat Walter Moderator] 8:53 pm: Have you done a lot of AVN
[Dr. Rogerson] 8:55 pm: No. Dr Mont has
probably done the most. They are the most unpredictable because hard to know how
much of the head is involved sometimes
[Dr. Rogerson] 8:56 pm: Mr. McMinn’s “Midhead” may be the best
solution for AVN in the future because it eliminates all the AVN
8:56 pm: Do you think that it’s reasonable for people to expect to be able to
run and jump on a resurfaced hip, or is that asking for too
[Dr. Rogerson] 8:57 pm: it is reasonable–run
,basketball ,tennis tetc.
[Pat Walter Moderator] 8:56 pm: Dr. Gross said he did a lot of
men with FAI – do you see a lot of that too?
Rogerson] 8:58 pm: yes for FAI.
have done several that have failed arthroscopic femoroplasty by
[Dr. Rogerson] 8:59 pm: Revised to
resurfacing for failed FAI scope
 8:59 pm: Somewhere out there in cyberspace (forgot where) there is a video of a BHR
patient jumping rope at just 2 weeks post-op. I find that not only foolish, but
potentially building up false expectations. Am I overreacting?
[Dr. Rogerson] 9:00 pm: I would agree with foolish
[Dr. Rogerson] 9:00 pm: taking quite of a risk for femoral neck
[B.I.L.L.] 8:59 pm: How do you position the cup ? Do you measure
it with instruments or is it “Eyeballed” ?
[Dr. Rogerson] 9:02 pm: Cup position is
positioned based on the anterior and posterior walls and the superior overhand
and cup positioner determined with pre-op x-ray templating
 9:00 pm: Certain PT ROM exercises create clunking in my hip 31
days post op. Should these exercises be stopped or are they potentially going to
cause problems with the clunking? (No pain)
[Dr. Rogerson] 9:04 pm: clunking can be from
various causes. A thump can be felt early on with the iliotibial band on the
outside of the trochanter and will fade. Also the psoas tendon can clunk deep
inside and usually stretches out but if the clunk occurs when the hip is flexed
and internally rotated that could mean subluxing and should be avoided. check
with your doc
[chillman] 9:02 pm: Do you feel that there are specific
tests that should be performed, in order for a patient or physician to determine if
the patient should pursue resurfacing vs. arthroscopic? I have been lucky that
I’ve not needed to see doctors with the exception of childbirth, so I’m not
shopping for drs. I’m looking for information so that I can make an informed
decision. I’ve seen 2 orthos, 1 chiropractor, and their opinions
[Dr. Rogerson] 9:06 pm: would definitely get a ct scan to evaluate
the impingement and the degree of arthritis and go from there
[Pat Walter Moderator] Thank You for participating in the
Chat. I know we have learned a great deal.
[Dr. Rogerson] 9:06 pm: My
[Pat Walter Moderator] 9:07 pm: You are welcome.
