[Selection of procedure in the management of recurrent juvenile and aneurismatic bone cysts].
Aneurysmal and juvenile bone cysts are characterized by frequent recurrence and pathological fractures caused by such bone cysts also recur frequently. Curettage of the cyst and spongiosaplasty is often unsuccessful. According to our experience, excochleation must be followed by drilling the cyst wall and fraising off the compact substance. Densely packed homologous spongiosa must then be implanted. In case of recurrence or if the cyst increases in size, radical en-bloc resection is indicated and the defect must be bridged by osteoplastic and osteosynthetic methods. We have treated four difficult cases successfully with this procedure. In one case, resection with limb shortening lead to full recovery.
