Traumatic Spondyloptosis of L4
Overview
Affiliations
Study Design: Case report of 2 patients with traumatic L4-L5 spondyloptosis.
Objective: To report the diagnosis and treatment of the traumatic L4-L5 spondyloptosis.
Summary Of Background Data: Traumatic L4-L5 spondylolisthesis is even rarer than traumatic L5-S1 spondylolisthesis. No case of traumatic L4-L5 spondyloptosis (anterolisthesis of Grade V) has been reported. The injury mechanism and surgery management merit more studies.
Methods: Through the posterior approach, both of the 2 patients underwent the decompression and reduction with pedicle screws. One had the posterolateral fusion and the interbody fusion from L4-L5 whereas the other had the posterolateral fusion from L4-S1.
Results: Complete reduction and fusion were achieved. The neurologic symptoms improved after the surgery. At follow-ups of 1 year and 6.5 years, there was no further slippage of the vertebrae. They were satisfied with the treatment outcomes.
Conclusion: Posterior decompression, reduction, internal fixation, and fusion is effective and dependable for traumatic L4-L5 spondyloptosis.
