Article Synopsis
  • Surgical treatment for cancer patients with epidural spinal cord compression has evolved significantly, particularly with the rise of minimally invasive surgical (MIS) techniques and separation surgery over the past 17 years.
  • A study of 383 patients showed increasing numbers of surgeries performed and a notable reduction in blood loss and transfusion rates, with those treated more recently experiencing better neurological improvements and mobility.
  • Despite these advancements in surgical technique and patient outcomes, overall survival rates remained unchanged, highlighting the need for a multidisciplinary approach to patient management.

Study Design: Retrospective Exact Matched case-control study.

Objectives: Surgical treatment delay in AIS due to family preferences is common. This study aims to quantify the increase in risks as the Cobb angle increases and provide a Quantifiable Risk Reference Table that can be utilized for counseling.

Study Design: Single-center retrospective review of outcomes among three surgical techniques in the treatment of thoracic idiopathic scoliosis (T-AIS) with a follow-up of at least 5 years.

Objective: To investigate how outcomes compare in video-assisted anterior thoracic instrumentation (VATS), all hooks/hook-pedicle screw hybrid instrumentation (HHF), and all pedicle screw instrumentation (PSF) techniques for T-AIS.

Summary Of Background Data: Studies comparing outcomes for anterior versus posterior fusion for T-AIS are few and with short follow-up.

Introduction: During the Coronavirus disease 2019 outbreak, while healthcare systems and hospitals are diverting their resources to combat the pandemic, patients who require spinal surgeries continue to accumulate. The aim of this study is to describe a novel hospital capacity versus clinical justification triage score (CCTS) to prioritize patients who require surgery during the "new normal state" of the COVID-19 pandemic.

Methodology: A consensus study using the Delphi technique was carried out among clinicians from the Orthopaedic Surgery, Neurosurgery, and Anaesthesia departments.

Study Design: Retrospective cohort study.

Objective: This study aimed to identify risk factors that predict lumbar curve adding-on in patients who had selective thoracic fusion.

Summary Of Background Data: Selective thoracic fusion offers deformity correction of Lenke 1 and 2 thoracic curves and maintains lumbar range of movement.

Unlabelled: MINI: This is a long-term prospective cohort study comparing the radiographic outcomes of anterior versus posterior instrumentation for Lenke 5 adolescent idiopathic scoliosis. Both approaches were comparable in terms of radiographic outcomes up to 10 years. The posterior approach is more prone to developing proximal junctional kyphosis.

Purpose: To determine the effect of preoperative embolization on intraoperative blood loss in surgery for metastatic spinal tumours stratified by tumour type, type of surgical approach and extent of surgery.

Methods: We retrospectively analysed 218 patients undergoing open surgery for metastatic spine tumours in our institution between 2005 and 2014. The cohort was divided to those who underwent preoperative embolization and those who did not.
