Transsacral transvertebral screw fixation and posterolateral fusion for spondyloptosis in an adolescent

Abstract

Spondyloptosis is a condition in which the L5 vertebral body dislocates completely from the sacrum anteriorly and descends into the pelvis. Surgical options include posterior and anterior fusion, single- or two-stage operation, and neural decompression. We performed a one-stage operation on an adolescent with spondyloptosis by using an L2–S1 ilium posterior fusion with pedicle screws, cement augmentation, transsacral transvertebral screw fixation (L5–S1), and sacropelvic fixation for an adolescent with spondyloptosis. The clinical result was satisfactory and demonstrated that transsacral transvertebral screw fixation provides a safe and reliable in situ fixation of spondyloptosis.
