[Reconstruction of tumor-induced bone defects with vascularized fibula graft].

OBJECTIVE
To study the methods and effects of the reconstruction of tumor-induced bone defects with vascularized fibula graft.


METHODS
From Oct. 1996 to Jan. 2005, 89 patients with bone defects were treated with fibula graft using different methods. Among the patients, 48 patients were male and 41 patients were female, ranging in age from 12 to 67 years, with an average of 35 years. Thirty-five patients were treated with inlay bone grafting after excision of focus, 15 patients were treated with single or double-strut fibula graft after tumor resection, 16 patients were treated with fibular head graft for juxta articular tumor resection, and 23 patients were treated with double-strut fibula combined with iliac graft after marginally resection.


RESULTS
Enneking evaluation system was used to evaluate therapeutic effects. Among 35 patients treated with inlay bone graft after excision, 29 patients were followed up, and 26 patients got an excellent result, 1 good and 2 poor. Among 15 patients treated with single or double-strut fibula graft after tumor resection, 12 patients were followed up, and 8 patients got an excellent result, 1 good, 1 poor and 2 bad. Among 16 patients treated with fibular head graft for juxta articular tumor resection, 12 patients were followed up, and 7 patients got an excellent result, 3 good,1 poor and 1 bad. Among 23 patients treated with double-strut fibula combined with iliac graft after marginally resection, 17 patients were followed up, and 11 got an excellent result, 3 good, 1 fair and 2 bad.


CONCLUSION
These treatment methods can greatly enrich the treatment methods for bone tumor, and satisfy the reconstruction after bone tumor excision in different position of the four limbs. These methods are reliable and can be chosen according to disease types.
