Anatomy of Thoracic Spine Kyphosis is natural alignment Narrow spinal canal Facet orientation Rib factor on stability Conus at T12-L1
Slide 3-

Anatomy of Lumbar Spine Lordosis is natural alignment Larger vertebral bodies Facet orientation Cauda equina
Slide 4-

Thoracolumbar Junction Transition Zone Kyphosis Lordosis Mechanical Difference: Lumbar spine less stiff in flexion
Slide 5-

Transition Zone:Predisposed to Failure Little opportunity for force dispersion Central loading of T-L junction Not anatomically disposed to transfer force

Anatomic Classification3 Column TheoryDenis 83 Based on radiographic review of 412 cases 5 types, 20 subtypes Anterior- ALL , anterior 2/3 body Middle - post 1/3 body, PLL Posterior- all structures posterior to PLL Same as Holdsworth Posterior injury-not sufficient to cause instability Anterior Middle Posterior
Slide 22-

McAfee Classification Six types CT based-100 patients Middle column most important
Slide 23-

Load Sharing Classification McCormack, Spine 1994 Review of injuries fixed posteriorly (McCormack 94) Which failed? Could they be prevented? Suggests when to go anteriorly Morphologic Classification 1930 ‘40 ‘50 ‘60 ‘70 ‘80 ‘90 2000 ‘10 CT evolved MRI evolved * Post elements important 2 column 3 column, McAfee Mechanistic classifications Load Sharing

Slide 48-

Reliability/treatment validity at single institution Treatment validity exceptional- 96.4% Moderate agreement for PLC (66%) and mechanism (60%) Spine, 2006
Slide 49-

Conflict: Mechanism vs Morphology
Slide 50-

The Journal of Spinal Disorders and Techniques Identifying objective findings on imaging studies and clinical examination instead of guessing injury mechanisms provides more valid understanding of injury classification
Slide 51-

Problems Inter-rater agreement on sub-scores was: Lowest for mechanisms followed by PLC Highest for neurological status Substantial for the management recommendation J. Neurosurgery Spine, 2006
Slide 52-

The Spine Journal, 2006 Status PLC Most reliable indicators: Vertebral body translation on plain radiographs Disrupted PLC components on T1 sagittal MRI Focal kyphosis in absence of vertebral body injury
Slide 53-

Assessment of Injury to the PLC in the Setting of on Normal Plain RadiographsLee, J., Vaccaro, A.R. et al. J Orthopaedic Trauma 2006Validation Study J. Orthopaedic Research Submitted 2006 STATUS PLC Disrupted PLC components i.e. ISL, SSL, LF; black stripe on T1 sagittal MRI , most important factor Diastasis of the facet joints on CT Fat suppressed T2 sagittal MRI
Slide 54-

IMPACT OF EXPERIENCE (attending surgeons, fellows, residents, and non-surgeon health care professionals). Most reliable among spine fellows, followed by attending spine surgeons. Lim, Coluna/Columna Journal, 2006
Slide 55-

IMPACT OF TRAINING Management component: reliability rose from κ = 0.46 (r=0.47) on first assessment to κ = 0.72 (r=0.91) on the 2nd assessment. Spine, 2007
Slide 56-

DIFFERENCES BETWEEN SPECIALTIES Inter-rater reliability: “injury mechanism” higher in neurosurgeons Assessment of PLC, neurological status- higher in orthopaedic surgeons Reliability total score/management recommendations similar Overall, differences subtle J Spinal Disorders, 2006
Slide 57-

DIFFERENCES IN NATIONALITIES Inter-rater reliability for mechanism higher among non-US surgeons Reliability for PLC, neurological status, management higher among US surgeons World J Emerg Surg, 2007
Slide 58-

Management of Thoracic and Lumbar Injuries CONTROVERSIAL!!!!
Slide 59-

Non-Operative Treatment of Thoracic Spine Injuries Brace or Cast Treatment Compression Fractures Stable Burst Fractures Pure Bony Flexion-Distraction Injury
Slide 60-

85 pts reviewed to determine late outcome of non-op management Chronic pain predominant in 69.4% 25% of subjects had changed jobs (most full to part) 48% of subjects filed lawsuits concerning injury Pain intensity correlated with angle of kyphosis But not w/magnitude of anterior column deformity Bed rest alone adequately manages traumatic, uncomplicated thoracolumbar wedge fractures Folman and Gepstein, J Orthop Trauma, 2003
Slide 61-

No correlation was found between radiological &functional parameters Vertebral column deformity that occurred after the injury was stable in 2-column; progressive in 3-column Significant remodeling of canal encroachment (CE) proportional to initial amount of CE but not related to age & radiology Agus, Eur J Spine, 2005 Evaluated 29 pts with 2- or 3-column-injured thoracolumbar burst fractures
Slide 62-

62% showing good or excellent outcome 38% showing moderate or poor outcome Significant effects on clinical outcome: Load-sharing classification, posttraumatic kyphosis & overall  lumbopelvic lordosis Surgical reconstruction appropriate treatment in more severe fractures Koller, Eur Spine J, 2008 Evaluated 21 pts; 9.5 yr f/u
Slide 63-

Surgical Management of Thoracolumbar Injuries Unstable burst fractures Purely ligamentous Facet dislocations Translational injuries Neurologic deficit
Slide 64-

Delayed diagnosis in 28 pts (19%) Differences b/w surgical & non:  in pulmonary complications & length of hospital stay in non-op pts. Surgical pts had highly significantly less pain Radiographic studies should be performed Choice of treatment in pts with multiple injuries is not different from that in pts with no asscd injuries Dai, J Trauma, 2004 147 pts w/acute thoracolumbar fractures: 1988 to 1997 Min. 3yr f/u; 4 pts died during hospital stay
Slide 65-

Lack of evidence demonstrating superiority of one approach over the other No evidence linking posttraumatic kyphosis to clinical outcomes Strong need for improved clinical research methodology to be applied to this patient population Thomas, J Neurosurg Spine, 2006 Evaluated scientific literature on operative & non-op treatments
Slide 66-

Reviewed 37 pts Accuracy of plain radiographs improved w/experience of observers Impact of disagreement on treatment plan was significant Plain radiography alone is not adequate Dai, Spine, 2008
Slide 67-

Extended anterolateral fixation is biomechanically comparable to circumferential fusion Extension of anterior instrumentation & fusion 1-level above and below the unstable segment can result in near equivalent stability to a 2-stage circumferential procedure Acosta, J Neurosurg Spine, 2008 Biomechanical comparison of 3 fixation techniques for unstable thoracolumbar fractures. Induced at L1: 1) Short-segment anterolateral fixation 2) Circumferential fixation 3) Extended anterolateral fixation
Slide 68-

Angular stable plate system showed higher primary and secondary stability In specimens with lower BMD, the use of angular stable systems substantially increased stability Disch, Spine, 2008
Slide 69-

Difficult to establish the ideal surgical approach Anterior decompression assocd w/ recovery of motor strength & bowel/bladder fxn;  pain & improve neuro status Stand-alone anterior constructs:  complications &  likely to have revision More definite evidence required to determine best surgical strategy Whang, J Am Acad Orthop Surg, 2008
Slide 70-

Conclusions on Treatment Surgically treating incomplete neuro deficits potentiates improvement and rehabilitation Complete neuro deficits may benefit from operative treatment to allow mobilization Little chance of developing neuro deficits with nonoperative treatment
Slide 71-

Surgery:Anterior versus Posterior Anterior More predictable decompression Saves levels Questionable improved recovery of neuro function Gertzbein,1992 – may be indicated in bladder dysfunction McAfee, 1985 – neuro recovery in 70 patients Posterior Less morbidity Failures with short –segment constructs Usually requires more levels Less blood loss Transpedicular anterior column bone grafting may protect posterior construct
