Whole Spine & General condition guides
Acute Postoperative Spine Complications
A guide to the early warning signs after spine surgery, so you know what is normal healing and what needs urgent attention.
Adjacent Segment Disease
A condition in which new, symptomatic degenerative changes develop at the spinal level immediately above or below a previously fused segment, causing pain, nerve symptoms, or walking difficulty.
Adult Spinal Deformity
A group of structural spine malalignments in adults that cause back pain, a progressive forward or sideways lean, and often leg pain or neurogenic claudication.
Burst Fracture
A burst fracture occurs when a vertebra is shattered by extreme compression, sending bone fragments outward and potentially into the spinal canal, where they can injure the spinal cord or nerve roots.
Cage Subsidence
A mechanical complication of spinal fusion surgery in which the interbody cage gradually sinks into the adjacent vertebral bone, potentially causing a return of pain or nerve symptoms.
Central Sensitization as a Spine Mimic
Central sensitization is a condition in which the nervous system becomes hypersensitive, producing widespread pain across many body regions that can closely resemble a pinched nerve or spinal cord problem.
Critical Limb Ischemia as a Spine Mimic
A limb-threatening loss of blood flow to the leg or foot that can be mistaken for severe spinal stenosis or radiculopathy, but requires urgent vascular care rather than spine treatment.
Epidural Lipomatosis as a Spine Mimic
Excess fatty tissue building up inside the spinal canal can crowd the spinal cord and nerves, producing pain and leg symptoms that look just like spinal stenosis.
Hardware Loosening
Gradual loss of fixation between spinal implants and bone after fusion surgery, which can cause new or recurring back or neck pain and sometimes requires revision surgery.
Hip Osteoarthritis as a Spine Mimic
Hip osteoarthritis frequently mimics lumbar spine conditions by producing groin, thigh, and buttock pain that overlaps with spinal nerve-root territories, making accurate diagnosis essential before any treatment is started.
Inflammatory Spondyloarthropathy as a Spine Mimic
Ankylosing spondylitis and related inflammatory spondyloarthropathies cause deep low back pain and stiffness that is often mistaken for a degenerative disc or joint problem until the inflammatory pattern is recognized.
Intradural Extramedullary Tumor
A tumor that grows within the spinal canal outside the spinal cord itself, compressing the cord or nerve roots and causing progressive pain, sensory changes, or weakness.
Intramedullary Spinal Cord Tumor
A tumor arising within the spinal cord's own tissue that expands the cord from inside, progressively disrupting movement, sensation, and bladder and bowel control.
Metastatic Epidural Spinal Cord Compression
A spinal emergency in which cancer spreading to the vertebrae compresses the spinal cord or cauda equina, causing escalating back pain, weakness, and potentially irreversible paralysis if not treated without delay.
Peripheral Neuropathy as a Spine Mimic
A disorder of the peripheral nerves that produces numbness, tingling, burning pain, and weakness resembling a spinal pinched nerve or cord compression.
Pseudarthrosis (Spinal Nonunion)
Pseudarthrosis is the failure of a spinal fusion to develop solid bone, leaving a residual mobile segment that can cause persistent pain and hardware stress.
Recurrent Disc Herniation
A new herniation of disc material at the same spinal level that was previously operated on, often causing leg or arm pain that feels similar to the original episode.
Sagittal Imbalance
A spinal alignment condition in which the trunk drifts forward of the pelvis, making upright standing and walking increasingly painful and exhausting.
Spinal Epidural Abscess
A collection of infected material in the space around the spinal cord that can rapidly compress nerves and cause potentially irreversible paralysis.
Spinal Metastasis
Cancer that has spread to the vertebral column, causing progressive back pain, risk of vertebral fracture, and, in serious cases, compression of the spinal cord or nerve roots.
Vascular Claudication as a Spine Mimic
Cramping leg pain caused by narrowed arteries during walking closely mimics the neurogenic claudication of lumbar spinal stenosis, making accurate diagnosis essential before any treatment begins.
Vertebral Compression Fracture
A structural collapse of the vertebral body, most commonly caused by osteoporosis, that produces sudden back pain and, with multiple fractures over time, progressive height loss and spinal deformity.
Vertebral Osteomyelitis and Discitis
A serious infection of the vertebral body and intervertebral disc that requires prompt diagnosis and prolonged antibiotic therapy, with surgery reserved for neurologic emergencies or spinal instability.
