The hip cold heals spontaneously. There is therefore no cure for this condition.
The child may be given symptomatic treatment for pain, and may prescribe rest ... as much as possible. After a few days, generally, everything comes back in order, and the child will have no sequel.
In rare cases, the pain persists for several days, requiring additional tests: an ultrasound of the hips, x-rays (which may reveal a lesion), and possibly a blood test.
In severe hip cold, bedding may be necessary. Treatment can be supplemented by equipment to pull on the diseased leg. A short hospitalization is then indicated. A few weeks later, a control x-ray may be performed.
It should be noted that relapses are possible in limited numbers. After varying delays, two to three relapses can occur on the same hip or contralateral hip. Some doctors offer a three-month imaging check in a systematic way. This precaution makes it possible not to miss an oste'ochondrite of the hip (more serious affection), revealed by an articular effusion.
The prognosis for a hip cold is therefore excellent overall, with no sequelae and progression to adulthood.
