Purpose: We evaluated the outcomes of surgical reconstructions using recycled autograft augmented with VFG for bone defects caused by tumor resections.
Materials and Methods : Ten patients with a malignant or locally aggressive bone tumor who were managed with recycled autograft augmented with VFG and followed up minimum 1 year were evaluated for bone union, functional result and complications. The influence of various factors on bone union and functional outcomes were also analyzed.
Results: Bone unions were obtained at 13 of 20 junctions. Average union time was 3.7 months at metaphyseal junctions and 8 months at diaphyseal junctions (P<0.05). At diaphyseal junctions, younger aged group and intramedullary location group showed earlier bone union (P<0.05). The mean functional score was 81%. There were 3 nonunions, 4 delayed unions and 2 recycled bone resorption combined with fractures.
Conclusion: To obtain excellent results, proper microvascular technique, sufficient length of VFG bridging both junctions, stable internal fixation and protection of reconstructed bone until union are necessary.
