Authors presented results in conservative treatment of 54 cases of hip joint with aseptic necrosis of thigh bone. In 22 hips, excluding the typical conservative treatment, EEP injections were given. However, in the remaining 32, different forms of relieve were used. The obtained results in the first group (A) confirm the purpose of enrichment in conservative treatment by adapting intra- articular injections of EEP especially in advanced stages of necrosis (III-IV period of illness) and also in those whose parents did not express their consent on surgery in the early stage of the illness.
