Objective: There has been minimal literature reporting on results of osteoporotic burst fracture with spinal canal compromise treated with percutaneous vertebroplasty. Vertebroplasty for treatment of osteoporotic burst fracture is controversial. We want to clarify whether the osteoporotic burst fracture with spinal canal compromise is a contraindication to percutaneous vertebroplasty. To compare the clinical and radiological results between osteoporotic burst and compression fractures treated with percutaneous vertebroplasty.
Patients And Methods: From 2005 through 2006, 23 osteoporotic burst fracture patients with asymptomatic spinal canal compromise and 41 osteoporotic compression fracture patients underwent percutaneous vertebroplasty. Pre- and post-operative pain scores, functional and radiographic results and complications were analyzed.
Results: The average canal compromise in study group was 15% (5-49%). The mean post-operative Oswestry Disability Index (ODI), Visual Analogue Score (VAS), kyphotic angle, vertebral body height measurement from the anterior, central and posterior part of the body are all significantly improved in both the study and control groups when compared to pre-operative data. However, there was no significant difference between study and control groups in pre- and post-operative ODI, VAS, kyphotic angle and improvement of body height. There were no significant differences (P=0.3797) in cement leakage rate between burst and compression groups (47.8% vs 36.6%). All the leakages were minor and without neurological deficit. The percentage of adjacent fractures in both groups also had no significant differences (39.1% in burst and 41.5% in compression group).
Conclusions: Osteoporotic burst fracture with asymptomatic spinal canal compromise is not a contraindication for percutaneous vertebroplasty. This procedure is suitable for both osteoporotic burst and compression fracture with careful surgical technique.

Vertebral fractures (VFs) occasionally appear as the first manifestation of acute lymphocytic leukemia (ALL) in children. However, in adults, it is uncommon for VFs to lead to a diagnosis of ALL, and surgical intervention is even rarer. We encountered a case of a 42-year-old man with ALL who presented with acute severe back pain, lower limb numbness, dysuria, and hamstring weakness.

Background Context: Percutaneous vertebroplasty for the treatment of osteoporotic burst fractures remains controversial. A previous study has shown that an osteoporotic burst fracture with asymptomatic spinal canal compromise is not a contraindication for percutaneous vertebroplasty.
Purpose: To determine whether these outcomes persist over a long term, we continued to observe patients in their short-term study over a long-term period.

Article Synopsis
- A study compared the effectiveness of percutaneous kyphoplasty combined with pediculoplasty (PKCPP) versus simple percutaneous kyphoplasty in treating severe osteoporotic vertebral fractures, finding that PKCPP offered better pain relief and spinal stability.
- The purpose was to evaluate PKCPP’s ability to address complex fractures, reduce refracture risks, and maintain vertebral stability.
- The study involved 96 patients and tracked clinical outcomes over a year, showing that while simple kyphoplasty had quicker surgeries and less cement used, PKCPP had superior therapeutic benefits.
Influence of Screw Length and Cement Position Within the Injured Vertebra on Fixation Strength in Short-Segment Fixation of Osteoporotic Thoracolumbar Burst Fractures.

Article Synopsis
- The study investigates percutaneous kyphoplasty and its effectiveness combined with short screw fixation for treating osteoporotic vertebral fractures, focusing on optimizing fixation strategies with varying screw lengths and bone cement use.
- Four different spinal models were tested under physiological loads to measure aspects like range of motion, implant stress, and stability, comparing the impact of screws with and without bone cement.
- Results show that while incorporating bone cement significantly improves biomechanical stability and stress distribution, using short screws without cement still provides adequate performance, suggesting a simpler surgical approach could be effective.

Objective: To retrospectively assess the Thoracolumbar Injury Classification and Severity Score (TLICS) in patients with osteoporotic vertebral compression fractures (OVCF) and compare the treatment given with that predicted by the TLICS score.
Methods: All medical records of patients presenting from January 2014 to November 2017 for acute atraumatic or low impact OVCF were screened, and eligible patients were retrospectively reviewed. The TLICS score was determined based upon magnetic resonance imaging (MRI) findings and clinical records.
