Expert’s comment concerning Grand Rounds case entitled “Floating lumbar spine: proposed mechanism with review of literature” (K. Das et al., Eur Spine J. doi:10.1007/s00586-016-4690-2)

[摘要] The paper describes a curious relatively low-energy injury that resulted in a traumatic L5/S1 spondyloptosis associated with multilevel pedicle avulsion fractures up to L2 [1]. The case serves to reaffirm a number of issues in the management of spinal trauma: the variation in presentation, the challenges to the current classification algorithms, the importance of understanding the injury mechanism, and the challenges in reduction, and stabilisation are just some to mention.
