Introduction: Bone defects too long to be bridged by cancellous bone graft require complex reconstruction. Distraction osteogenesis requires long duration and has pin-site complications and nonunions. Patients and
Methods: We evaluated 25 patients who underwent structural Allograft replacement of bone defects were assessed from 2008 to 2012 with mean followup of 18 months (6 months – 3 yrs). The age of patients ranged from 16 to 67 yrs with mean age being 37.5 yrs. Five patients had bone loss following tumour resection, 17 patients had large segmental bone loss of supracondylar femur, 3 patients had segmental metaphyseal bone defect. Three patients with tibial bone loss and 9 patients with supracondylar bone defects underwent reconstruction with fibula allograft, Three patients underwent allograft femur with intramedullary free vascularised fibula transfer and Three patients had undergone allograft femur with autografts.
Results: 15 Patients with Supracondylar femur bone loss had good incorporation of allograft, one patient went on to have non union of shaft and fibula junction however didn’t undergo secondary procedure. Two patients had post operative deep surgical site infections which settled after debridement and antibiotics. The range of movements of the knee joint are, however restricted to 50 to 100 degrees of flexion. Five patients with tumour resection had good incorporation of allografts and no recurrence found till now. The average time of incorporation of allograft is about 8 months.
Conclusion: Single stage reconstruction of bone defects by structural allografts gives good results when compared with other methods and it is applicable to patients with bone loss of epiphyseal, metaphyseal, or diaphyseal origin.
