I can’t recall the last metatarsal phalangeal joint (mpj) replacement that I’ve done in the past 25 years, but as the winds of fate blew…I had two this week. One was for a likely Freiberg’s infraction of the 3rd mpj and the other was post traumatic degeneration of the 2nd mpj following surgery.
Does implant arthroplasty work well for these cases? I can’t say that I really know. I have such a limited case load to be able to draw from. The basic premise though is to preserve the weight bearing surface of the metatarsal while creating a pain free joint.
The Freiberg’s case was really in need of repair. Upon entering the joint, a large loose fragment of bone and cartilage came loose.
We’ll have to see how these folks do over time. At their first post-op visit, I was very impressed with the lack of pain that they had. X-ray findings were good in both cases.
I reckon you’ll just have to stay tuned…
