Hi there tharsheblows!
Someone told me abotu your thread so I searched for it - hope you see it!
My dd2, who is 4 and a half, has also just ben diagnosed with Perthes. She already has obvious degeneration and fracture of her femoral head and total involvement, which is most common in girls, I hear. I feel crap as I have spend 3 months telling her to get a move on and stop moaning, and now I find that she is really unwell.
The consultant said we are looking at 18 months of restriction of activity like NO running, jumping and limited walking (we have an OT referral to hopefully get a maxi buggy and possibly a trike for her) though she can swim as much as posssible (he said 3-4 swimming sessions a week) and ride her bike when we can. She will have to be on restriction of activity when she starts school - no PE and either supervision or staying in at lunch/breaks come August.
He said that the latest theory is that Perthes is caused by delayed bone age, which for us fits with dd2 being smaller in every way than her older siblings. They are researching this at Yorkhill in Glasgow (our hospital, which is pretty much the UK centre for Perthes as it is more common in Scotland for some reason) and will be following her up for this until she is 18.
The hardest thing for me is that dd2 is in a lot of pain on a regular basis but they said at the hospital that painkillers are counerproductive as they encourage movement when the joint needs to rest. Pain is a warning - and when it hurts, out consultant recommends rest rather that painkillers, except at night. SO I had a weeping, hurting, crying dd today, that I wasnt supposed to give any treatmetn to (and an hour of nintendo ds connecting with very-bad-at-any-Mario-game dod seemto help!) The main issue for her is that we live in a lovely quiet cul-de-sac with many kids and she is used to running about with them, and now cant.
It woudl be good to hear from you. I know your ds is a lot older but it is nice to be in touch with others inthe same situation, even though at 10 it is a different management issue.
Take care of yourself - I already realise it is taking its toll on me, mentally, though its bothing to do with me, not my fault!
