High-Yield Summary The NOMS framework integrates Neurologic, Oncologic, Mechanicaland Systemic factors to guide individualized management of metastatic spine disease, optimizing outcomes through multidisciplinary decision-making. Neurologic assessment focuses on the degree of epidural spinal cord compression and neurologic deficits, directing the need for decompression. Oncologic evaluation considers tumor radiosensitivity and systemic disease burden, influencing the choice […]
High-Yield Summary The Enneking classification stratifies primary spinal tumors by grade, local extentand metastasis, directly guiding surgical margins and reconstruction strategy. Tumor grade (benign vs. malignant) and compartmental involvement (intracompartmental vs. extracompartmental) dictate the aggressiveness of resection. Enneking’s system emphasizes achieving wide or marginal margins for malignant tumors to reduce recurrence and improve survival. Surgical […]
High-Yield Summary Spinal tuberculosis (Pott’s disease) primarily affects the anterior vertebral body and intervertebral disc, leading to progressive kyphotic deformity and potential neurological compromise. Diagnosis hinges on MRI for early detection and biopsy for microbiological confirmation; ESR and CRP are useful adjuncts but nonspecific. Non-operative management with multi-drug anti-tubercular therapy (ATT) remains first-line for uncomplicated […]
High-Yield Summary Spinal epidural abscess (SEA) is a neurosurgical emergency characterized by infection in the epidural space, requiring rapid diagnosis and often urgent surgical decompression to prevent permanent neurological deficits. Classic clinical triad: fever, back painand neurological deficit; however, early presentation is often nonspecific, demanding high clinical suspicion. MRI with gadolinium contrast remains the gold […]
High-Yield Summary Degenerative lumbar scoliosis (DLS) in the elderly results from asymmetric disc degeneration and facet arthropathy, leading to coronal and sagittal imbalance with predominant back pain and neurogenic claudication. Surgical indications hinge on progressive deformity with neurological compromise or intractable pain refractory to optimized conservative management. Radiographic assessment must include full-length standing scoliosis films […]
High-Yield Summary Sagittal balance is critical for maintaining efficient posture and minimizing energy expenditure; disruption correlates strongly with pain and disability in spinal deformity and degenerative conditions. Key radiographic parameters include pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), lumbar lordosis (LL)and sagittal vertical axis (SVA); their interplay guides surgical planning. Mismatch between pelvic […]
High-Yield Summary Cervical laminoplasty decompresses the spinal cord by expanding the spinal canal while preserving posterior elements, minimizing post-laminectomy instability and kyphosis. Key anatomical considerations include the laminae, facet jointsand the vertebral artery course; preserving facet integrity is critical to maintain stability. Surgical approaches primarily include open-door and double-door laminoplasty, chosen based on pathology location […]
High-Yield Summary C1 (atlas) fractures primarily involve the anterior and posterior arches; stability hinges on the integrity of the transverse atlantal ligament (TAL). Non-displaced, stable fractures with intact TAL are managed conservatively with rigid cervical immobilization. Displaced fractures or those with TAL disruption require surgical stabilization to prevent atlantoaxial instability and neurologic compromise. Surgical options […]
High-Yield Summary Sacral fractures require precise classification to guide management; instability and neurological involvement are key determinants for surgery. The Denis classification remains the cornerstone for assessing fracture zone and neurological risk, while the AO Spine Sacral Classification refines surgical decision-making. Non-operative treatment is reserved for stable, non-displaced fractures without neurological deficit; operative intervention is […]
High-Yield Summary Basilar invagination (BI) and platybasia represent craniovertebral junction (CVJ) deformities causing brainstem and upper cervical spinal cord compression, often requiring precise radiographic assessment and tailored surgical intervention. Key surgical goals include decompression, stabilization, and realignment; choice of approach depends on reducibility and neurological status. Dynamic imaging and CT-based morphometrics guide classification and operative […]
