Abstract：Objective To explore the feasibility of limited long-segment fusion for the patients with degenerative lower lumbar scoliosis but no severe thoracolumbar kyphosis.Methods Thirty-six patients with degenerative lower lumbar scoliosis who underwent spinal surgery from June 2003 to September 2012 were included in this retrospective study. There were 10 males and 26 females, whose average age was 59.7 years old ( range: 55-73 years ). The apical vertebrae was from L3 to L4 and the end vertebrae was L2 or L3, with T10-L2 kyphosis <20°. They were divided into limited long-segment fusion group (n=16, upper end vertebrae L2 ) and long-segment fusion group (n=20, upper end vertebrae T9-11 ). The radiographic parameters and Oswestry disability index ( ODI ) scores were compared between the 2 groups preoperatively and in the latest follow-up.Results There were no statistically signiifcant differences between the 2 groups preoperatively and in the latest follow-up in lumbar Cobb’s angle, lumbar lordosis, pelvic tilt, sacral slope, T10-L2 kyphosis, proximal junctional kyphosis and ODI scores (P>0.05 ). No proximal junctional kyphosis was found in the limited long-segment fusion group.Conclusions The limited long-segment fusion is effective for the patients with degenerative lower lumbar scoliosis but no severe thoracolumbar kyphosis.
