Answer to the Letter to the Editor of Huilin Yang et al. concerning manuscript 'Percutaneous augmented instrumentation of unstable thoracolumbar burst fractures', Eur Spine J, 2011 Dec 8 [doi:10.1007/s00586-012-2278-z], by N. Rahamimov et al.

摘要

Controlling cement leakage is indeed an important technical consideration when performing any type of vertebral augmentation, even though the consequences of such leakage are often more radiographic than clinical [1]. We appreciate the important technical tips provided in this letter and are certain of their efficacy. Unfortunately, two-stage cementing is not a viable option when augmenting an intact vertebra to prevent screw pullout, and other measures are needed to address this issue.
