Study Design. In vitro biomechanical study. Objective. This study aimed to investigate the
biomechanical effects of facet joint violation (FV) on mobility and optically tracked intervertebral …

OBJECTIVE S2 alar-iliac (S2AI) screw fixation effectively enhances stability in long-segment
constructs. Although S2AI fixation provides a single transarticular sacroiliac joint fixation (…

Purpose Due to brain shift during bilateral deep brain stimulation (DBS) surgery, placement
of the second electrode may be subjected to more error than that of the first electrode. The …

Purpose: A challenging aspect of glioma surgery is to distinguish tumour tissue from surrounding
eloquent structures and perform resection with accuracy. Various technologies have …

Study Design. Biomechanical study of range of motion (ROM) at the vertebral levels
adjacent to the construct of posterior pedicle screw-rod fixation with different types of lumbar …

Objective The high mechanical stress zone at the sudden transition from a rigid to flexible
region is involved in proximal junctional kyphosis (PJK) physiopathology. We evaluated the …

BACKGROUND CONTEXT Previous studies have concluded that LLIF, TLIF, and PLIF with
posterior pedicle screw-rod fixation (PSR) provide equivalent stability in cadaveric …

Background Although intraoperative magnetic resonance imaging (iMRI) has an established
role in guiding intraoperative extent of resection (EOR) in cranial tumor surgery, the details …

BACKGROUND CONTEXT The lumbar level above the fusion segment is the most common
level for the development of adjacent level instability. The posterior ligamentous complex (…

Background During brain surgery, the neurosurgeon must be able to identify and avoid injury
to the Rolandic cortex. However, when only a small part of the cortex is exposed, it may be …
