title: [The value of homologous spongiosa in en-bloc resection of juvenile bone cysts of the upper arm].
abstract: The recurrence rate after excochleation and homogeneous bone grafting of juvenile and aneurysmal bone cysts is high. One of the reasons is the poor vascularisation of the wall of the cyst. En-bloc resection is recommended in cases of recurrence after curettage and bone grafting and in cases of prior conservative treatment after pathological fracture followed by a rapid growth of the cyst. Excellent results of en-bloc resection in 8 cases of humerus bone cyst are reported. Good vascularisation of the juvenile periosteum and the surrounding soft tissue is most important for new bone formation after homogeneous bone grafting.
