[The surgeon's procedure in dystrophic bone cysts in children]

The authors set apart childhood dystrophic cyst as a separate nosological unit. The underlying factor of the development of a bone cyst is dysplasia of vessels filling the bone-marrow canal and a concomitant dystrophic process in the surrounding bone tissue. The nonneoplastic nature of the cysts led to the search for sparing methods of treatment, namely, the puncture method. The administration of demineralized bone shavings during therapeutic puncture (after osteoperforation of the wall, scraping off the fibrous membrane) produces good results. The clinical material consists of 46 cases. There were 8 cases of aneurysmal bone cyst, 23 with active and 15 with passive bone cysts. In 44 cases treatment by two or three punctures led to recovery in 2-4 months. In 2 patients with aneurysmal bone cysts three punctures proved ineffective and an operative intervention was undertaken. It is concluded that treatment by puncture is indicated in dystrophic bone cysts. Operation is indicated in poor outcomes of puncture treatment in patients with aneurysmal bone cysts.
