AbstractINTRODUCTION: Reconstruction and stabilization after total en bloc resection of spinal tumours often requires adjunct of allograft/bone substitutes. However, the efficacy of both graft substrates to obtain solid fusion remains unclear. This study assessed the role of autograft in comparison to allograft for spinal reconstruction following total en bloc spondylectomy in a rather large series of patients. METHODS: This study included fourteen spinal tumor patients (mean age: 28-years; range: 12-61 years) underwent total en bloc spondylectomy and reconstruction using autogenous bone graft (n=7 iliac crest (ICBG)); allograft bone alone (n=4) or a mixture of local bone and allograft bone (n=3). The minimum follow-up was 2 years (mean: 5 years; range: 2-13 years). Bony fusion was determined on X-ray or CT-scan. Spondylectomies involved one (57%), two (14.3%), three (14.3%), four (7.1%) and 5 levels (7.1%) from T1 to L5. RESULT: In patients with ICBG, all patients demonstrated solid fusion at final follow-up. Of the allograft alone patients), none achieved fusion. In patients with mixed autograft and allograft fusion was achieved in 66.7% cases with single level resections. Instrumentation failure was noted only in the allograft alone group (25% of allograft cases). 80% of the patients without solid fusion maintained normal daily activities. CONCLUSIONS: In this large series, our study noted that autogenous bone graft remains superior to allograft for spinal reconstruction following en bloc spondylectomy. When the use of allograft becomes inevitable in long reconstruction, the patients should be alerted of the possibility of delayed union, non-union and instrumentation failure.
