Measurement of neck rotation is currently reliant on radiologic imaging. Given the radiation exposure for CT imaging and the additional inconvenience for the patients, an alternative assessment is needed. Goniometers are comfortably to use and easy to access, also for private consulting. The aim of this study was the assessment of whether a handheld goniometer can be used for accurately measuring the rotation of C1-C2. ⋯ The goniometer is exact to impartially determine the percentage contribution of C1-2 rotation to total neck rotation.

A unilateral vertical sacral fracture that exits medial or through the L5-S1 facet joint is considered to affect the lumbo-sacral integrity, and it is denoted as an indication for surgical fixation. However, no studies have analysed the outcomes after non-operative treatment of such injuries. ⋯ Our study indicates that 47% of Isler's fractures were mechanically stable and could be effectively treated non-operatively with good radiological and functional outcomes.

Anterior lumbar spine arthrodesis has been increasingly prescribed. In order to obtain better exposure of the intervertebral discs, it is necessary to identify vascular structures depending on the level to be approached. Systematic ligation of the iliolumbar vein has been suggested for access to the L4-L5 level, which may be technically challenging. The goal of the present study was to determine a safe limit for separating the iliolumbar vein safely without the need for its ligation. ⋯ Systematic ligature is not necessary for accessing the anterior route to the L4-L5 level, leading to a reduction in the time of surgery and avoiding serious vascular injuries that can occur.
