Abstract:
Objective To evaluate the long-term clinical efficacy of iliac bone block allograft in anterior reconstruction of thoracolumbar fractures.Methods A follow-up study was carried out on 93 patients with thoracolumbar fractures treated by anterior decompression and interbody fusion with iliac bone block allograft from February 2004 to March 2007.The radiographic and clinical outcomes were retrospectively assessed.Results Sixty-six patients were followed up for 60-97 months (mean,78 months).The effective interbody fusion rate was 100％,with the fusion time of 6-12 months (mean,10 months).The Cobb' s angle corrected from pre-operative (21.6 ± 8.3)° to post-operative (5.8 ±5.2)°,but when the infusion became effective,the angle showed average loss of 2.4°.All the 66 patients were associated with various degrees of neurological deficiency,but the patients with incomplete nerve dysfunction obtained different degree of recovery.Conclusions Iliac bone block allograft is effective in reconstruction of spinal anterior-middle column stability with the aid of internal fixation instruments.Thereby,it may be a potential alternative to autograft in the treatment of thoracolumbar fractures and can attain early and late stage persistent spinal stability.
