[Internal fixation of meta- and diaphyseal intercalary bone defects after tumour resection with intramedullary nailing and porous polymethylmetacrylate (PMMA) spacer].

Abstract

Radical resection of bone tumours localized in the meta- or diaphysis of long bones frequently results in segmental defects. Several stabilization techniques with preservation of the adjacent joint have been published, but the failure rate appears to be considerable. The objective of this study is the experimental and clinical testing of a new technique which combines unreamed nailing with support of the defect by a porous polymethylmetacrylate (PMMA) spacer.
