The accuracy of pedicle screw insertion in pediatric scoliosis correction surgery using augmented reality technology in combination with a conventional navigation system was evaluated, and its usefulness was verified. A retrospective study of patients who underwent mixed reality technology-assisted posterior scoliosis correction and fixation was conducted. In total, 361 pedicle screws inserted with a mixed reality technology-assisted navigation system were analyzed; 25 pedicle screws (6.9%) showed Rao Classification Grade 1 deviation, whereas 0.83% showed Rao Classification Grade 2.3 deviation, which is a clinical deviation. In terms of the relationship between the rotation of the vertebral body and the deviation of the pedicle screw, the pedicle screw tended to deviate more easily when it was necessary to insert the pedicle screw in a more strongly oblique position due to the rotation of the vertebral body. The results suggest that the pedicle screw insertion accuracy with augmented reality technology may be superior to that with conventional navigation alone in scoliosis correction and fusion surgery for scoliosis in children. This system is expected to become a standard support tool for spine surgery and will contribute to improving the success rate of surgery and reducing the burden on the surgeon.

Posterior lumbar screw fixation is the most common surgical method for lumbar disc herniation, but patients often face multiple complications postoperatively. The occurrence of screw track loosening can lead to fusion failure and even life-threatening screw track extrusion. However, there is currently a lack of animal models specifically targeting changes in the screw track following lumbar screw fixation.

Background: Iatrogenic thoracic aortic injury (TAI) is a rare but well-recognized complication of spine surgery, lacking standardized treatment guidelines due to its rarity and variability of manifestations.
Methods: We present a new case of TAI successfully managed with endovascular repair and systematically reviewed 52 articles (1991-2024) reporting 64 cases, including demographics, surgical indications, injury patterns, and treatments.
Results: A 53-year-old man with a T7 fracture underwent posterior spinal instrumentation and developed chest pain due to a combination of impingement and screw penetration into the thoracic aorta and was treated with thoracic endovascular aortic repair (TEVAR) and removal of pedicle screws.

Background: The lateral transpsoas lumbar interbody fusion is associated with transient postoperative anterior thigh and inguinal dysesthesias and hip flexor weakness from manipulation of the psoas and interposed lumbar plexus. However, it remains unclear whether this translates to higher pain scores and opioid requirements.
Methods: Patients who had undergone one- or two-level extreme/direct (XLIF/DLIF), anterior (ALIF), or transforaminal lumbar interbody fusion (TLIF) between January 2018 and December 2023 for degenerative spinal pathology were included.

Purpose We aimed to compare postoperative changes in intervertebral foraminal areas and the mechanisms of foraminal stenosis following fixation surgery for cervical spondylotic myelopathy (CSM) with local kyphosis and instability, using three-dimensional computed tomography (3DCT). Methods We retrospectively analyzed 55 patients who underwent posterior cervical spinal fixation using pedicle screws. A total of 71 spinal levels (C2/3 to C7/T1) and 144 intervertebral foramina with anchor screws inserted in the upper and lower vertebrae were examined.

Background: Posterior lumbar fusion (PLF) has become one of the most common spinal surgery procedures. Early symptomatic loosening of the pedicle screw could be a critical complication, leading to pseudarthrosis. However, revision strategies for pedicle screw loosening are still under debate.
