An osteoporotic wedge fracture is a type of vertebral compression fracture in which the front (anterior) portion of the vertebral body collapses, forming a wedge shape. These fractures occur with minimal trauma—often from everyday activities like bending, lifting, or even coughing—because the bones are weakened by osteoporosis. They most commonly affect the thoracic spine (mid-back) and can lead to height loss, spinal curvature (kyphosis), and chronic pain PhysiopediaPubMed Central.
Anatomical Background
Structure & Location
Vertebral Body: The thick, cylindrical front portion of each vertebra, responsible for weight-bearing.
Region Affected: Most often the mid-to-lower thoracic vertebrae (T7–T12), where bending forces concentrate Cleveland Clinic.
Origin & Insertion
Unlike muscles, vertebral bodies have no origin or insertion. They serve as anchor points for intervertebral discs above and below, transmitting loads through the spine.
Blood Supply
Segmental (Radicular) Arteries: Enter through the vertebral pedicles to supply the vertebral body.
Nutrient Arteries: Small vessels that branch within the bone marrow, maintaining bone health Best Practice.
Nerve Supply
Periosteal Nerves: Sensory fibers in the periosteum (outer bone lining) detect pain when the bone compresses or fractures.
Functions of a Healthy Vertebra
Weight Bearing: Supports head, torso, and arm loads.
Protection: Shields spinal cord housed in the vertebral canal.
Motion: Works with discs and facets to allow bending, twisting, and extension.
Attachment: Anchors ligaments and muscles that stabilize posture.
Shock Absorption: Cushions vertical loads via intervertebral discs.
Hematopoiesis: Bone marrow produces blood cells within vertebral bodies.
Types of Vertebral Compression Fractures
Wedge Fracture: Front of vertebra collapses; most common in osteoporosis.
Crush Fracture: Entire vertebral body collapses uniformly.
Burst Fracture: Vertebra shatters in multiple directions; often unstable and may impinge nerves Cleveland Clinic.
Additionally, fractures are classified as
Stable: Bone fragments remain aligned.
Unstable: Fragments shift, risking nerve injury.

Frequently Asked Questions
What exactly is an osteoporotic wedge fracture?
A collapse of the front part of a vertebra due to weak bones.Can it heal on its own?
Mild fractures often heal with rest and bracing over 6–12 weeks.Will I regain my lost height?
Some height may return with kyphoplasty, but permanent loss can occur.Is surgery always needed?
No—most cases manage with non-surgical care unless unstable or severe.What pain relief is safest long-term?
Acetaminophen and low-dose NSAIDs with bone-protected therapies.How soon can I exercise after diagnosis?
Gentle walking and physical therapy usually begin within days.Are braces effective?
Yes—support reduces pain and prevents further collapse.What diet changes help bone health?
Increase dairy, leafy greens, fatty fish, and limit caffeine.Can supplements cause harm?
Excess calcium may risk kidney stones; always follow dosing.How often should bone density be checked?
Every 1–2 years if fracture risk remains high.What’s the role of vitamin D?

Osteoporotic wedge fractures are common, painful, and can significantly impact quality of life. Early diagnosis, a combination of non-pharmacological strategies, medications, and—in select cases—surgical interventions can optimize healing, restore function, and prevent future fractures. Regular exercise, a balanced diet, and bone-protective therapies form the cornerstone of both treatment and prevention.
