Introduction: The autologous bone graft harvested from the posterior iliac crest for spinal fusion presents osteogenic, osteoinductive and osteoconductive advantages; however, its disadvantages include a limited amount of available material and an incidence of donor site complications ranging from 8% to 39%, including donor site pain, neurovascular injury and pelvic fractures. Objectives: To compare the posterior iliac crest corticoancellous harvest using a chisel-gouge approach versus a curette approach; to evaluate intra-operative and post-operative complications; to quantify the harvested bone; to grade donor site pain. Materials and Methods: Prospective randomized study in 34 consecutive patients for posterolateral fusion of the thoracic and lumbosacral spine; 26 women and 8 men, between 15 and 79 years of age. Subjects were divided into two groups. Group 1: curette approach; and Group 2: chiselgouge approach. The evaluation included: the amount of bone harvested, the time required and complications. Results: Group 1: 19 patients, 14 women and 5 men. The procedure lasted an average of 9.94 min, and the harvested material averaged 9.26 g. Denis Pain Scale scores at the first follow-up survey: 13 patients scored 1; 5 scored 2; 1 scored 3. Denis Pain Scale scores at the third follow-up survey: 15 patients scored 1; 2 scored 2; 1 scored 3. Group 2: 15 patients, 12 women and 3 men. The procedure lasted an average of 8.6 min, and the harvested material averaged 9.26 g. Denis Pain Scale scores at their first follow-up: 10 patients scored 1; 2 scored 2; 3 scored 3. At the third follow-up, all patients scored 1. Conclusions: We observed that the posterior iliac crest graft harvested using the chisel-gouge approach is faster, provides more graft and results in less pain at 60 days.
