Posterior wedging of the L5 vertebral body is a structural deformity in which the height of the back (posterior) side of the L5 vertebra is reduced relative to its front (anterior) side, creating a wedge shape oriented toward the spinal canal. This deformity may be congenital or acquired and can lead to altered spinal alignment, increased local stress, and potential nerve compression in the lumbosacral region. Quantitatively, posterior wedging is assessed by measuring anterior and posterior vertebral heights on lateral radiographs or MRI and expressing the ratio or percentage height loss, as detailed by Yildiz et al. in their morphometric analysis of lumbar vertebral heights ResearchGate. Although anterior wedge fractures are far more common—typically resulting from flexion forces—posterior wedging often reflects hyperextension injuries, developmental anomalies, or specific pathological processes. Severity can be graded using the Genant semiquantitative method, which classifies any vertebral height loss (anterior, middle, or posterior) into mild (Grade 1: 20–25% loss), moderate (Grade 2: 25–40% loss) and severe (Grade 3: > 40% loss) categories Radiopaedia.
Types
There are two complementary ways to classify posterior wedging of the L5 vertebra:
Etiologic Categories
Congenital: Developmental malformations (e.g., hemivertebrae) in which one half of the vertebral body fails to form normally, producing a wedge shape that may preferentially affect either anterior or posterior height RadiopaediaResearchGate.
Traumatic: Hyperextension or high-energy axial loading injuries that compress the posterior column, occasionally producing a posterior wedge pattern rather than the classic anterior wedge seen in flexion injuries U of U Medicine.
Osteoporotic: Fragility fractures due to decreased bone mineral density causing collapse of vertebral cortices—posterior involvement corresponds to osteoporotic fractures with posterior wall compromise in OF classification types 3–5 NCBI.
Pathological/Neoplastic: Lytic lesions (metastases, multiple myeloma) or benign tumors (e.g., hemangiomas) can weaken posterior trabeculae, leading to partial collapse and wedging BioMed CentralPMC.
Infectious/Inflammatory: Pyogenic or tuberculous vertebral osteomyelitis can erode the posterior vertebral body, resulting in wedge deformity; ankylosing spondylitis may also produce wedging through chronic inflammatory remodeling NCBIPubMed.
Metabolic: Disorders such as osteomalacia (vitamin D deficiency) or Paget’s disease lead to poor mineralization or disorganized remodeling, respectively, causing posterior collapse in severe cases NCBIPMC.
Iatrogenic: Post-surgical decompression (e.g., laminectomy) or radiotherapy can weaken the posterior elements, predisposing to wedge collapse.
Severity (Genant) Grades
Grade 1 (Mild): 20–25% posterior height reduction ﹘ minimal change, often asymptomatic Radiopaedia.
Grade 2 (Moderate): 25–40% posterior height reduction ﹘ may alter biomechanics and produce pain.
Grade 3 (Severe): > 40% posterior height reduction ﹘ significant kyphotic angulation, potential neurologic compromise.
Posterior wedging can be classified by etiology and severity:
Congenital Posterior Wedging
Hemivertebra: A unilateral failure of vertebral body formation leading to a wedge-shaped bone RadiopaediaScienceDirect.
Developmental Hypoplasia: Underdevelopment of the posterior vertebral body, often detected incidentally on imaging ScienceDirectNCBI.
Traumatic Posterior Wedging
Compression Fracture (AO Type A1): Low-energy axial loading causes isolated endplate depression, sometimes sparing the anterior column but collapsing the posterior vertebral height RadiopaediaNCBI.
Burst Fracture with Posterior Dominance: High-energy trauma causing comminution, including posterior fragments, may produce a wedge deformity preferentially oriented posteriorly NCBI.
Degenerative Posterior Wedging
Disc Degeneration–Induced Wedge: Asymmetric disc height loss (e.g., more loss posteriorly) leads to vertebral tilt and posterior reduction in vertebral height RadiopaediaRadiology Masterclass.
Facet Arthropathy–Related Wedge: Chronic facet joint hypertrophy creates a lever arm causing micro-compression of the vertebral body posteriorly Physiotutors.
Severity Grading (adapted from Genant’s classification in reverse)
Grade 1 (Mild): Posterior height loss ≤20% of original vertebral height.
Grade 2 (Moderate): Posterior height loss 21–40%.
Grade 3 (Severe): Posterior height loss >40%.
Causes of L5 Posterior Wedging
- Primary Osteoporosis
Age-related loss of trabecular bone density weakens the vertebral body uniformly. In some patients, the posterior cortex bears disproportionate stress during upright posture, leading to collapse of the posterior half of L5 and wedge formation. Fragility fractures in osteoporosis classically involve the anterior column, but posterior wedge patterns can occur in advanced bone loss NCBI. - High-Energy Trauma
Motor vehicle collisions or falls from height can subject the lumbar spine to hyperextension and axial loads. The posterior vertebral cortex may fail under these forces, producing a reverse wedge deformity at L5. Such injuries often coexist with posterior element fractures and ligamentous disruptions NCBI. - Metastatic Neoplasm
Secondary tumors (e.g., breast, prostate, lung metastases) infiltrate vertebral marrow and erode bony trabeculae. When lesions localize to the posterior half of the L5 body, the weakened bone collapses under normal loads, creating a wedge deformity. Radiographs often show mixed lytic and sclerotic changes before collapse Wikipedia. - Multiple Myeloma
Clonal plasma cell proliferation produces osteolytic lesions that compromise vertebral integrity. In roughly half of newly diagnosed patients, vertebral compression fractures—sometimes posterior‐predominant—are present at diagnosis, contributing to wedge deformity at L5 PMCAmerican Journal of Neuroradiology. - Tuberculous Spondylitis (Pott Disease)
Mycobacterium tuberculosis infection of the vertebral body leads to caseous necrosis and subchondral collapse. Although anterior wedging and kyphosis are most common, posterior involvement can occur, especially when subligamentous spread extends beneath the posterior longitudinal ligament Radiopaedia.

Frequently Asked Questions
What causes posterior wedging of L5?
Posterior wedging may arise from congenital spine shape variants, compression fractures (e.g., osteoporosis), or chronic uneven loading due to poor posture or spondylolisthesis.How is it diagnosed?
Diagnosis is by imaging—standard lumbar X-rays show the wedge shape; MRI assesses disc and nerve involvement.Is it reversible?
While bone shape cannot fully revert, pain and functional impact can be managed well with therapy and lifestyle changes.Will it lead to disc herniation?
It increases mechanical stress on the L4–L5 disc, raising the risk of bulging or herniation over time.Can exercise make it worse?
Improper exercise can aggravate pain; however, guided core-stabilization and flexibility exercises usually help.Are braces effective?
Short-term use of a lumbar brace can off-load painful movements but is not a long-term solution.How long does non-surgical treatment take?
Most patients see meaningful relief within 6–12 weeks of consistent therapy and lifestyle modification.When is surgery indicated?
Surgery is considered for severe, persistent pain unresponsive to 6 months of conservative care or if neurological deficits develop.Can I swim with this condition?
Yes—swimming and aquatic therapy reduce spinal load while building strength.Are injections helpful?
Epidural steroid injections or facet joint injections can provide months of pain relief in select patients.What is the role of weight loss?
Even modest weight reduction decreases lumbar compressive forces, alleviating pain.Can posture correction alone fix it?
Posture training is critical but works best combined with strengthening, flexibility, and ergonomic adjustments.Is electric stimulation safe?
TENS and interferential therapy are generally safe and drug-free ways to manage pain.Will this shorten my lifespan?
No—while it can impact quality of life, with proper management most people maintain active, healthy lifestyles.How often should I follow up with my doctor?
