High-Yield Summary Spondylolysis is a stress fracture of the pars interarticularis, predominantly affecting adolescent athletes engaged in repetitive hyperextension and rotational spinal loading. Diagnosis hinges on high-resolution imaging: initial plain radiographs often miss early lesions; CT and MRI provide definitive assessment and staging. Non-operative management with activity modification and bracing achieves union in the majority […]
High-Yield Summary Acute Central Cord Syndrome (CCS) typically presents with disproportionate upper extremity weakness relative to lower extremities, often following hyperextension injury in a cervical spine with preexisting spondylosis. Early MRI is essential to assess cord edema, hemorrhage, and underlying canal stenosis, which guide prognosis and surgical planning. Non-operative management remains appropriate for neurologically stable […]
High-Yield Summary The Thoracolumbar Injury Classification and Severity Score (TLICS) integrates injury morphology, posterior ligamentous complex (PLC) integrity, and neurologic status to guide management. TLICS ?3 favors non-operative treatment; scores ?5 indicate surgical intervention; a score of 4 requires individualized clinical judgment. Accurate assessment of PLC injury via MRI is critical, as it significantly influences […]
### High-Yield Summary – Atlantoaxial subluxation (AAS) involves abnormal alignment or instability between C1 (atlas) and C2 (axis), risking spinal cord compression and neurologic compromise. – Key surgical indications include persistent instability, neurologic deficits, and failure of conservative management in inflammatory, traumatic, or congenital etiologies. – Radiographic evaluation hinges on dynamic flexion-extension lateral cervical spine […]
High-Yield Summary The AO Spine Subaxial Cervical Injury Classification System stratifies injuries by morphology, neurologic status, and clinical modifiers, directly guiding surgical decision-making. Injury morphology is categorized into Types A (compression), B (tension band disruption), and C (translation/rotation), each with distinct biomechanical implications. Neurologic status grading (N0–N4) informs urgency and extent of decompression; modifiers (M1–M4) […]
High-Yield Summary Odontoid fractures account for 10-15% of cervical spine fractures, predominantly affecting elderly patients with osteopenia and younger patients after high-energy trauma. Anderson and D’Alonzo classification remains the cornerstone for guiding management, with Type II fractures posing the highest risk of nonunion and often requiring surgical fixation. Non-operative management with rigid cervical immobilization is […]
High-Yield Executive Summary Spinal fracture management hinges on fracture stability, neurological status, and patient comorbidities; unstable fractures or those with neurological compromise generally require surgical intervention. Classification systems such as the AO Spine Classification and Thoracolumbar Injury Classification and Severity Score (TLICS) guide treatment decisions by integrating morphology, neurological status, and posterior ligamentous complex integrity. […]
What Are the Surgical Options for Treating Spinal Cord Herniation? High-Yield Executive Summary Spinal cord herniation (SCH) is a rare but potentially reversible cause of progressive myelopathy, most commonly idiopathic and ventral in the thoracic spine. Surgical intervention is indicated for progressive neurological deficits or myelopathy; the goal is to reduce herniation and repair the […]
Understanding the Different Types of Spinal Injections and Their Indications High-Yield Executive Summary Spinal injections serve both diagnostic and therapeutic roles in managing axial and radicular pain, with selection guided by precise anatomical targets and clinical presentation. Epidural steroid injections (ESIs) are the most common, subdivided into interlaminar, transforaminal, and caudal approaches, each with distinct […]
High-Yield Executive Summary Spinal orthoses are adjuncts to stabilize, immobilize, or offload the spine in trauma, deformity, degenerative conditions, and postoperative care; their selection depends on injury pattern, spinal level, and patient factors. Rigid thoracolumbosacral orthoses (TLSO) provide three-point fixation critical for stable thoracolumbar fractures without neurological deficit, while cervical collars vary in immobilization efficacy […]
