A Retrospective Study on the Treatment of Stage II Kümmell's Disease With Cement-Augmented Short-Segment Internal Fixation (KD-CASSIF)

The First Affiliated Hospital, Guangzhou University of Traditional Chinese Medicine60 enrolled

Overview

This retrospective study compares the clinical and radiographic outcomes of percutaneous vertebroplasty (PVP) versus cement-augmented short-segment percutaneous pedicle screw fixation for the treatment of single-level stage II Kümmell's Disease (KD). A total of 60 patients who failed conservative treatment for at least 6 weeks and completed a minimum of 3 months of follow-up were included. The primary outcomes are Visual Analogue Scale (VAS) for low back and lower limb pain, and Cobb's angle correction and maintenance rates. Secondary outcomes include Oswestry Disability Index (ODI), vertebral anterior height maintenance rate, implant-related complications, and reoperation rate. This study aims to provide evidence for optimizing treatment strategies in stage II KD.
