[Warning: long post]
Much has happened since my last post! Tuesday by chance we got to meet
Terri, another of Dr. Mayo's PAO patients who has been super helpful. She was in for her pre-op appointment before having a PAO on her other hip--four months after a PAO on her other hip! She had the ideal recovery from her first PAO, the best recovery story I've read. She's recovering from PAO #2 as I write this, and so far it sounds like it's going as well as #1.

But I'm getting ahead of myself. An update on the last three weeks: relatively uneventful. My hip has felt solid the last few weeks, like the bone has fused enough for it not to flex when I move this way or that. I can roll onto my non-operated side in bed and lie on it for some time without too much discomfort. I can do just about everything myself, including getting in and out of the shower, getting all my clothes on (except for my right sock if it's tight). My right gluteus maximus is on vacation--it's just flat. My incisions have healed well; to the right is a picture from about a week ago. The pressure sores on my heels are basically healed.
Tuesday Krista drove me in for my eight-week follow-up appointment--eight weeks from my SDH, seven weeks from my PAO. It was good to see everyone in the office again.
First they sent me off to get a bunch of x-rays next door. One x-ray required me to spread my legs a bit and turn my toes inward, to rotate my femur inward as much as possible, but I wasn't able to rotate it at all. I was hoping that was just due to muscle atrophy, since I've been very careful to observe Dr. Mayo's restrictions.
Then back to the office. Sara came in with the x-rays and slapped them up on the light box for us to look at. All those bone cuts have healed well. There remains a little gap where the top cut above the acetabulum was made but it will close up. The trochanter cut for the SDH seems to have healed perfectly. Nine screws of varying lengths and seven suture anchors are visible on the x-ray. (I'd put up pictures but for some inexplicable reason the IT department didn't allow an orthopedic surgeon's office to run DICOM software which would allow them to view the x-rays!)
Dr. Mayo also patiently answered a bunch of questions about the repairs he made. If I understand correctly, the labrum was torn pretty much all along the front of the acetabulum, which is why seven suture anchors were required to sew it back. He's confident that it has/will reattach itself to the acetabulum. I'm guessing this was caused by the thickened neck of the femur impinging on the retroverted acetabulum. He also trimmed down the neck of the femur to minimize impingement (see the illustration at the beginning of
this post).
There was also an apparent lesion near the top of the femoral head. One doctor diagnosed it as
osteochondritis dissecans. It looked like it might be a little divot. But what Dr. Mayo found was a small bump on the femoral head that also scored the surface of the acetabulum. He performed an
OATS procedure, removing a 10 mm plug of bone and cartilage where the bump was, and transplanting a plug of bone and cartilage from the edge of the femoral head, where the cartilage is less crucial. The plug is press-fitted and the bone should fuse with the surrounding bone. That should stop the damage to the cartilage in the acetabulum.
Dr. Mayo expects my hip should last at least 10 years, maybe more, but he thinks I'll probably need a hip replacement someday. I would be very grateful for 10 more years; it would definitely be worth it.
But the x-ray showed some bad news too:
ectopic bone has formed in front of my hip socket, where I was opened up, enough to severely limit my range of motion--Dr. Mayo estimates I have a range of motion of about 20˚ before the ectopic bone starts impeding movement. As I understand it the bone is not what we normally think of--like a solid chunk--but is rather bone cells interwoven with the muscles. Evidently when these cells are traumatized by something like surgery they can differentiate either into scar tissue or fibroblasts, or they can differentiate into bone.
The treatment is another two or three hour surgery. The approach would be the same as for the PAO, and would require detaching a couple of muscles again. Dr. Mayo would hack out (he prefers the term "morselize," borrowed from spinal docs) the ectopic bone from the surrounding tissues. Recovery would be much easier, since I would still be able to bear full weight, but I would again be restricted from lifting my leg straight up while those muscles re-anchor. While he's in there, Dr. Mayo would remove most of the screws. By my count four would stay: two to reattach one of the muscles he detaches by chiseling off a chunk of bone (because bone-to-bone heals better than muscle-to-bone); and the two in the trochanter, since those would not be accessible through the PAO incision.
Shortly before surgery I'd get a single dose of targeted radiation to the area, to preemptively inhibit the cells that would want to turn to bone after this surgery. Evidently I'd need another CT scan before then to help the radiology/oncology guys do their targeting.
Surgery would happen sometime after the four month mark. The bone needs that much time to mature in order to be able to differentiate it from the surrounding tissues. In the meantime, I'll stay busy with PT, limited by my range of motion. Dr. Mayo said there's no point in trying to force it; I'd just make it "angry."
Before these surgeries Dr. Mayo told me that the likelihood of this happening was increased because we were doing two surgeries close together, so it wasn't a total surprise. Had we known how everything was going to turn out we might have done the two surgeries six months apart, but then I would have had two long recoveries rather than one.
But all this ectopic bone is just a speed bump (no pun intended). The important part is that the repair appears to have been successful.
So now I'm trying out my new hip. I'm limping around the house with one crutch reasonably well, better the more weight I put on the crutch. Without the crutch all I can do is lurch around, almost hopping on my good leg. I have PT orders so I'll need to find a physical therapist and get busy.
I'm very grateful to God for how he's working in all this. And I couldn't be happier with the care Dr. Mayo and Sara give.
