Thoracolumbar Fracture Classification System A New Approach Spine Trauma Study Group Alexander R Vaccaro M.D. Professor Thomas Jefferson University Department of Orthopaedics and the Rothman Institute

Fracture Description (Morphometric) Spine Trauma Study Group Thoracolumbar Classification System Three Part Description Fracture Description (Morphometric) Neurologic Status Integrity of PLC

Fracture Description (Morphology) Compression-axial, flexion,distraction,translation/rotation Distraction- extension,flexion,translation/rotation, compression Translation/Rotation-flexion, distraction

Neurologic Status Intact Nerve Root Injury Cauda Equina Injury Cord Injury-Incomplete, Complete

Posterior Ligamentous Complex Intact Disrupted In Tension

Treatment Determined by: Mechanism Neurology Ligament/ bone Integrity

Mechanism-Point System Two Component Mechanistic Description Compression 1 Translation / Rotation 3 Distraction 3

Neurology-Point System Intact Nerve root Cauda equina 1 3 Cord Incomplete Complete 3 2

Stability-Soft Tissue Point System Ligaments Intact 0 PLC Injured 3 Evaluated by MRI

Stability Spinal Column Point System Anterior Posterior 1 1 Middle 1

Next Step - Direct TX Assign Points Conservative Surgery

Translation/Rotation - 3 Point System Mechanism Ligament Translation/Rotation - 3 PLC - 3 Distraction - 3 Compression - 1 Neurology Spinal Column Cauda equina - 3 Anterior - 1 Incomplete - 3 Middle - 1 Complete - 2 Posterior - 1 Root - 1

Treatment Fractures with 4 points or less = non operative Fractures with 5 points=Nonop vs Op Fractures with 6 points or more = surgery

Examples Anterior Compression Fx Compression ( mechanism) - 1 Intact (neurology) - 0 PLC (ligament) no injury - 0 Anterior Column - 1 Total 2 points- Non Op

Example Stable Burst Fracture Compression (mechanism) - 1 Intact ( neurology) - 0 PLC (ligament) no injury (0) Ant/Middle column 1+1 Total 3 points-Non Op

Example Unstable Burst-Complete Neuro Injury Compression (mechanism) -1 Complete (neurology) - 2 PLC (ligament) injury - 3 Ant/Middle column -1+1 Total 8 points-Surgery

Example Stable Burst-Complete injury Compression-1 Complete neurology-2 PLC Intact-0 Anterior, Middle Column disruption- 1+1 Points 5-Non Op vs Op

Example Fx Dislocation Translation/rotation - distraction (mechanism) - 3 + 3 Complete (neurology) - 2 PLC (ligament) injury - 3 Anterior column - 1 Total 12 points-Surgery

Surgically Indicated Patients Approach Selection Neurology Ligament Status Modifiers

Approach Selection Posterior alone vs. Neurologically Intact Ligament Injury present Posterior alone vs. Anterior alone vs. Combined

Approach Selection Combined vs Neurologically Incomplete Ligament Injury No Yes Combined vs Anterior Anterior Modifier – Osteoporosis Combined

Approach Selection Neurologically Complete Injury Posterior

Thoracolumbar Fracture Classification System Point system to determine nonoperative vs operative treatment Neurology, ligamentous status helps determine surgical approach Validation necessary
