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
