From 1987 to 1993, we performed spinal osteotomy with posterior closing-wedge using a single-operation technique in 20 patients with kyphosis. Spinal deformity resulted from mal union after spinal injury in 13 patients and from ankylosing spondylarthritis in 7. Mean duration of the procedure was 4 h 15 min (range 2 h 30 min to 7 h) for mal union and 3 hours (2 h 30 to 4 h) for ankylosing spondylarthritis. ⋯ There were no fatal complications nor neurological or vascular complications among the 20 patients. There were 4 complications in patients with an abnormal callus including 3 mechanical complications and one deep infection. For spondylarthritis, there were no complications at maximum follow-up.
