Severe flexion deformity of spine may produce considerable functional disability. Correction of the deformity by osteotomy of the spine has been associated with severe complications (Goel 1968, Law 1962, Mc Master 1962, Salter 1961, Smith Peterson et al. 1945). In a single case report Wilson and Levine (1969) reported successful correction of the deformity (due to ankylosing spondylitis), by one stage bilateral iliac osteotomy with Harrington instrumentation. We are reporting bilateral pelvic osteotomy procedure in a case of severe flexion deformity of the spine due to ankylosing spondylitis.
