Management of L1 Superior Endplate Fracture

Initial Assessment and Classification

The American College of Radiology recommends obtaining CT imaging immediately to characterize the fracture pattern, assess for canal compromise, vertebral collapse, and kyphotic deformity 1
A thorough neurological examination should be performed to document any deficits, as this fundamentally changes management, according to Neurosurgery guidelines 2, 3
The American Association of Neurological Surgeons suggests calculating the TLICS score to guide treatment decisions, with scores ≤3 suggesting conservative management and scores ≥5 indicating surgical intervention 4

The American Association of Neurological Surgeons provides a Grade B recommendation that management with or without external bracing produces equivalent outcomes, based on Level I randomized controlled trial evidence 5, 4
Pain control with analgesics and early mobilization as tolerated is recommended, according to Praxis Medical Insights 4
TLSO bracing is optional and should be based on physician discretion, with a maximum duration of 8 weeks to avoid trunk muscle atrophy, as suggested by the American College of Physicians 5, 4

For thoracolumbar fractures requiring surgery, the American Association of Neurological Surgeons recommends that anterior, posterior, or combined approaches may be used, with no significant impact on clinical or neurological outcomes (Grade B recommendation) 6, 7
The posterior approach is recommended for most thoracolumbar pathology, offering greater surgeon familiarity and lower complication rates, according to Neurosurgery guidelines 8
The Load Sharing Classification (LSC) should be considered for burst fractures, with scores 7-9 points benefiting from combined anterior-posterior fixation, as suggested by the American Association of Neurological Surgeons 2, 3

Repeat imaging is necessary to monitor for progressive vertebral collapse, increasing kyphotic deformity, and delayed instability, according to Praxis Medical Insights 8
Approximately 40% of conservatively treated patients may have persistent pain at 1 year, and one in five will develop chronic back pain despite conservative treatment, as reported by the American College of Physicians 4

Any neurological deficit present requires immediate surgical consultation, according to the American Association of Neurological Surgeons 5, 4
Significant vertebral collapse, angulation, or canal compromise also requires immediate surgical consultation, as suggested by the American College of Surgeons 5, 4
A TLICS score >4, suggesting instability, is an absolute indication for surgical evaluation, according to the American Association of Neurological Surgeons 5, 4

Non‑steroidal anti‑inflammatory drugs (NSAIDs) are recommended as the first‑line pharmacologic agents for pain control in patients with mild vertebral compression fractures. 9
Opioid analgesics should be reserved for severe pain and used with caution because of risks of sedation, nausea, and falls. 10

The majority of patients experience spontaneous resolution of fracture‑related pain within 6–8 weeks, even in the absence of medication. 10

Extended bed rest increases the likelihood of complications and delays functional recovery, providing no advantage over early mobilization. 10

Most patients treated conservatively achieve complete resolution of symptoms. 10
Approximately 40 % of patients may retain some degree of pain at 1 year post‑injury. 10
Around 20 % (one in five) may develop chronic back pain despite non‑operative management. 10
