In a human cadaveric burst fracture model with and without longitudinal ligament damage, the amount of anterior and posterior bone displacement (ABD, PBD) during balloon vertebroplasty after pedicle-screw instrumentation was investigated quantitatively. ⋯ It is suggested that balloon vertebroplasty after pedicle-screw instrumentation may safely be used, in terms of bone displacement and cement leakage, in fracture types where damage to longitudinal ligaments is to be expected.
-
Study of interrater reliability. ⋯ This study shows that multiple raters, with training and guidelines, can reliably score pain drawings, and high consistency in the subsequent classification of cases of widespread pain can be obtained from such data.

A reliability study of the Modic classification. ⋯ We have shown that the classification is both reliable and reproducible. It is simple and easy to apply for observers of varying clinical experience. We therefore recommend its use in clinical research and practice.

A prospective case control study design was conducted. ⋯ While performing percutaneous vertebroplasty, the surgeon is exposed to a significant amount of radiation. Proper surgical technique and shielding devices to decrease potentially high morbidity are mandatory. Training in radiation protection should be an integral part of the education for all surgeons using minimally invasive radiologic-guided interventional techniques.

An unusual case report of cervical stenosis presenting with the Brown-Séquard syndrome. Technical considerations and a literature review are discussed. ⋯ Multilevel chronic cervical stenosis can present with an acute Brown-Séquard syndrome. Cervical laminectomy and decompression are effective treatments for cervical stenosis with an acute Brown-Séquard syndrome.
