In a human cadaveric burst fracture model, the amount of endplate fracture reduction after posterior instrumentation and balloon vertebroplasty was investigated quantitatively. ⋯ Reduction of endplate fractures, both in the center and at the periphery, seems feasible and safe with combined fracture reduction and balloon vertebroplasty. The endplate fracture reduction that was gained by inflation of the bone tamps could not be maintained after deflation.

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.
-
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 observational prospective cohort study in general practice. ⋯ The results found in this study indicate that besides clinical characteristics, psychological factors also predict the outcome of neck and shoulder symptoms.

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.
