Triple pelvic osteotomy is an accepted technique to correct acetabular dysplasia and degenerative labral pathology in young adults. Few papers mentioned the rate of nonunion at site of osteotomy of pubic bone and ischeal bone. No report about nonunion at site of osteotomy of iliac bone (up to the author's knowledge). Here the author reported a case of triple pelvic osteotomy which is complicated by painless nonunion at site of osteotomy of iliac bone which required excision of pseudarthrosis and autologous bone grafting. Healing was achieved after three months.
