From: The patterns of loss of correction after posterior wedge osteotomy in ankylosing spondylitis-related thoracolumbar kyphosis: a minimum of five-year follow-up

Fig. 4

29-year-old male (a) without fully ossified thoracolumbar structure (b)(c) underwent L2 PSO (d). Moderate loss of correction in GK and lumbar lordosis LL at the follow-up of 84 months were identified (e). The loss of correction mainly resulted from the increased KPNS and DIDW. (OVA: osteotomized vertebra angle; KPNS: kyphotic angle of proximal non-fused segments; DIDW: distal intervertebral disc wedging; GK: global kyphosis; LL: lumbar lordosis)
