Avulsion of ischial tuberosity

I started to suffer to a pain in the upper hamstring where it connects to the buttock. My physio suspected a bursis(?) problem and referred me to a specialist. An X-ray revealed that I have an avulsion of the ischial tuberosity. Basically I am told it has been caused by a fragment of bone detaching itself from the pelvis at the time I pulled the hamstring. However I pulled my hamstring when I was 15 years old, and I am now 48!! Over this time the detached bone has calcified. The x-ray showed the deformity of the pelvis where this occured.
I have felt some pain in that area over the years but generally it cleared up. Now it hurts particularly after sitting down eg a long car journey. I was running up to 40 miles per week when it got so bad I had to rest. I have been resting for 9 weeks now and recently tried gentle jogging without reaction.
The specialist said there is no treatment available, but didn’t suggest I give up running.
Has anybody heard of this before, and what advise can you give? I have an ambition to run a marathon. Is this wise, will the damage get worse? Is there any strength training I can follow?

    Hmmm. I don’t known anything in particular about your problem that is happening with your hip, but it does also sound a lot like Oshgood Schlater’s disease and heel spurs. Both are caused by a tendon pulling away from where it connects to the bone and eventually results in calcification. People having these conditions tend to have recurrect tendonitis–infrapatellar tendonitis, “runner’s knee”, the the case of Oshgood Schlater’s disease and plantar fascitis in the case of heel spurs.

    It’s hard to say whether or not you should give up training for a marathon. I guess that if you have a lot of patience and are willing to put a lot of time into stretching your hamstrings and taking it slower than you would without the injury you’d be okay, as long as you don’t have any pain.

    I would also highly recommend that you start off doing a lot of pain-free brisk walking before you get into too much running. Doing this before running will hopefully help strenghten your hamstrings and such before you actually being running.

    I hope this helps!
