legg calves perthes disease. can affect the hip joint in children usually presenting with relatively mild but persistent hip thigh or knee pain. initial treatment especially for younger children is observation and rest. the long-term prognosis is good especially when this occurs at a younger age as in this case. care should be managed by an orthopedist who after a period of rest and observation will probably be able to allow gradually more and more activities. most kids with lcp can ride bikes though he'll work up to that as his condition improves. i don't know of any diet changes or supplements that are likely to help. since he'll be relatively sedentary for at least a little while and spending more time indoors you will want to make sure he's getting enough calcium and vitamin d.
are there any supplements that can help improve my 5 year old's early-stage lcpd (legg calves perthes disease)?
