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

摘要

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.
