Article: Incidence and risk factors of adjacent segment degeneration in lumbosacral or lumbo-iliac fusion with L2 as the uppermost instrumented vertebra.

Authors (excerpt): Chun-Po Yen, Brian J Park, David Ben-Israel, Rakesh Kumar, Hong Joo Moon

Overview: OBJECTIVE: Lumbosacral or lumbo-iliac fusion may be warranted in patients with symptomatic diffuse lumbar spondylosis or mild to moderate lumbar spinal deformity. Depending on the extent of pathology, the L2 vertebra may be chosen as the uppermost instrumented vertebra (UIV) to avoid fusion crossing the thoracolumbar junction. However, the incidence of adjacent segment degeneration (ASD) following L2 to sacrum or ilium fusion has not been well studied. The authors aimed to determine the incidence of ASD following instrumented fusion in adult patients undergoing L2 to sacrum or ilium fusion and to identify the risk factors for this complication. METHODS: The medical records of adult patients who underwent decompression and lumbosacral or lumbo-iliac instrumented fusion for diffuse lumbar spondylosis, degenerative scoliosis, or sagittal malalignment with L2 as the UIV between January 2016 and December 2023 were retrospectively…
