Elucidate whether it is preferable to use the reference frame (RF) middle attachment (RFMA) method over the edge of the planned pedicle screw (PS) insertion area for RF placement in the surgery for adolescent idiopathic scoliosis (AIS) with intraoperative computed tomography (CT) navigation. ⋯ The RFMA method in thoracic scoliosis surgery for AIS with intraoperative CT navigation could significantly decrease the number of CT scans and blood loss while maintaining a comparable PS perforation rate to RF placement at the distal end of the planned PS insertion range.

Review Meta Analysis
Transforaminal lumbar interbody fusion using banana-shaped and straight cages: meta-analysis of clinical and radiological outcomes.
Transforaminal lumbar interbody fusion (TLIF) surgery rate increased over the last decade. There is no consensus about the better shape of cage to use in TLIF. This meta-analysis was conducted to compare the shape focusing on bony union, lordosis restoration as well as perioperative complications. ⋯ Straight-shaped cages had a better restoration of lumbar lordosis, disc height, and a lower subsidence rate when compared to banana-shaped cages. This may be explained by the absence of the optimal placement of the curved cages, which is at the most anterior part of the disc space. Better conducted randomized controlled trial could strengthen these findings.

Patients with spinal deformities undergoing corrective surgery are at risk for iatrogenic spinal cord injury (SCI) and subsequent neurological deficit. Intraoperative neurophysiological monitoring (IONM) allows early detection of SCI which enables early intervention resulting in a better prognosis. The primary aim of this literature review was to search if there are threshold values of TcMEP and SSEP in the literature that are widely accepted as alert during IONM. The secondary aim was to update knowledge concerning IONM during scoliosis surgery. ⋯ Concerning SSEP, a loss of 50% in amplitude and/or an increase of 10% of latency is widely accepted as an alert. For TcMEP, it seems that the use of highest threshold values can avoid unnecessary surgical procedure for the patient without increasing risk of neurological deficit.

Orthopaedic patient education materials (PEMs) have repeatedly been shown to be well above the recommended reading level by the National Institute of Health and American Medical Association. The purpose of this study is to create a standardized method to improve the readability of PEMs describing spine-related conditions and injuries. It is hypothesized that reducing the usage of complex words (≥ 3 syllables) and reducing sentence length to < 15 words per sentence improves readability of PEMs as measured by all seven readability formulas used. ⋯ The current study shows that using this standardized method significantly improves the readability of spine-related PEMs and significantly increased the likelihood that PEMs will meet recommendations for being at or below the sixth-grade reading level.

Studies from developed countries suggest a dramatic increase in the utilization of spine surgery in recent decades, however less is known about spine surgery rates in the developing world. The aim of this study was to investigate ten-year trends in the incidence of spine surgery within South Africa's largest open medical scheme. ⋯ Spine surgery in the South African private healthcare sector bears some similarity to developed countries in that it is dominated by elective procedures for degenerative pathology. However, the findings did not reflect the marked increases in the utilization of spine surgery reported elsewhere. It is hypothesized that this may be partly related to differences in the supply of spinal surgery.
