Posterior Cruciate Ligament Tibial Avulsion treated with Open Reduction and Internal Fixation

Abstract

The optimal treatment for thoracolumbar fractures (TLF) without neurological deficit remains controversial. Majority of the systematic reviews and meta-analyses have evaluated open operative approaches but have yet to compare the outcomes of minimally invasive percutaneous pedicle fixation (MIPPF) versus non-operative treatment. A retrospective cohort study was performed to compare clinical and radiological outcomes between MIPPF and conservative groups for TLF AO Type A1 to Type B2 during a 2-year follow-up period. Pre-operative plain and CT films were evaluated and decision made for short segment (non-fusion) MIPPF. Patients who refused operation were treated conservatively with three months of body cast, brace, or corset. MIPPF group showed earlier Visual Analog Score (VAS) improvement at six months post-injury (0 vs 6.0- p0.050). MIPPF as a method of internal bracing can be pursued in the treatment of TLF, with larger future cohorts and RCTs being called for to support and explore new findings.
