Article Abstract
Objective: To explore the clinical effects of posterior short-segment pedicle screw internal fixation combined with vertebroplasty for the treatment of Kümmell disease with kyphosis.
Methods: Twenty-four patients with Kümmell disease complicated with kyphosis treated by posterior short-segment pedicle screw internal fixation combined with vertebroplasty from January 2016 to December 2018 were retrospectively analyzed, including 6 males and 18 females, aged 63 to 85 (73.1±6.5) years old. The clinical effect was evaluate by visual analogue scale (VAS), Oswestry Disability Index (ODI), the anterior height of injured vertebral body, and the sagittal Cobb angle of the affected segment beforeoperation, at 3 days and final follow up after operation. And the surgical complications were observed.
Results: All 24 patients were followed up from 12 to 24 months with an average of (15.5±3.2) months. The VAS score was decreased from 5.21±1.06 preoperatively to 2.38±0.58 at 3 days postoperatively and 1.71±0.75 at final follow-up;ODI was decreased from (50.4±13.5)% preoperatively to (20.9±8.0)% at 3 days postoperatively and (16.7±9.6)% at final follow-up;the anterior height of injured vertebral body was restored from (8.0±4.2) mm before surgery to (18.1±5.0) mm at 3 days after surgery and (16.8±5.1) mm at final follow up;the sagittal Cobb angle of affected segment was decreased from (19.5±6.3)° preoperatively to (7.6±2.1)° at 3 days after surgery and(8.4±1.7)° at final follow-up. VAS, ODI, anterior height of injured vertebral body, and sagittal Cobb angle of affected segment were significantly improved at 3 days after operation and at final follow-up (<0.05). Two patients had complications, including asymptomaticcement leakage in 1 patient and superficial wound infection in 1 patient.
Conclusion: Posterior short-segment pedicle screw internal fixation combined with vertebroplasty for the treatment of Kümmell disease with kyphosis has relatively small surgical trauma, excellent clinical results, good vertebral height recovery, satisfactory correction of kyphotic angle, and fewer complications, etc. It is a safe and effective surgical method to treat Kümmell disease with kyphosis.

Thoracic aortic injury as a complication of spinal surgery: A new case and systematic review (1991-2024).
J Vasc Surg Cases Innov Tech

Faculdade de Ciências Médicas de Alagoas, Vascular and Endovascular Surgery Division, Alagoas, Alagoas, Brazil.
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.
Comparative analysis of acute postoperative pain and opioid use between lateral transpsoas, anterior, and transforaminal lumbar interbody fusions.

Spine Institute of Connecticut at St. Francis Hospital, Hartford, CT, United States.
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.
Impact on the Intervertebral Foramen After Posterior Cervical Fixation Surgery Using Cervical Pedicle Screws.

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.

Objective: Reveal the changing rule of the positional relationship between the uncinate process of cervical spine and vertebral artery by measuring the relevant parameters between the uncinate process of cervical spine and vertebral artery in different age groups.
Methods: A retrospective study was conducted on 1240 cases of cervical spine imaging data from 2018 to 2021 in the Radiology Department of the Affiliated Hospital of Inner Mongolia Medical University. The distance between the uncinate process superior ridge and vertebral artery and the maximum of pedicle transverse angle, the minimum of pedicle transverse angle, the range of pedicle transverse angle and the pedicle width were measured according to age groups.
