Pseudoarthrosis After Spinal Fusion Surgery Explained

What is pseudoarthrosis of the cervical and lumbar spine?

Pseudoarthrosis of the cervical and lumbar spine

Individuals may need a spinal fusion to treat a fractured vertebra, scoliosis, or conditions like spinal stenosis, degenerative disc disease, and spondylolisthesis/slipped vertebrae. A spinal fusion reduces pain and stabilizes the spine by limiting movement between vertebrae. Pseudoarthrosis happens when the bones don’t heal after a fracture or bone surgery. When pseudoarthrosis affects the cervical or lumbar spine, it means that two vertebrae did not heal and grow together after spinal surgery to fuse them (spinal fusion). Reasons for a failed spinal fusion include:

  • Issues with the instruments used to stabilize the bone
  • Lack of bone growth
  • The number of vertebrae being fused.

The patient’s health and lifestyle play a role in failed fusions, which can include

  • Diabetes
  • Inflammatory health conditions increase the risk
  • Smoking
  • Long-term steroid use

In many cases, revision surgery is needed.

Surgery-Related

During a spinal fusion, surgeons insert a bone graft between two vertebrae and then apply spinal fixation hardware (instrumented spinal fusion) that includes:

  • Plates
  • Rods
  • Screws
  1. The bone graft promotes growth between the two bones.
  2. The hardware stabilizes the vertebrae and prevents movement while they fuse and grow together.
  3. The hardware goes inside, or internal fixation.
  4. Although rare, a severe spinal fracture or deformity may need external fixation.
  5. A rigid frame secured outside the body helps to stabilize the bones.

If the fusion fails, it could be caused by one or more of the following surgical issues:

Number of Vertebrae Being Fused

Hardware

  • The surgeon must carefully plan and use the right hardware.
  • The type of hardware used during a spinal fusion may influence bone healing.
  • The instruments can come loose or break, interfering with the fusion process.
  • Spinal osteoporosis, having thin, weak bones, can affect fixation.
  • Even with the optimal surgical preparedness, weak bones significantly increase the chance of the instruments loosening and pseudoarthrosis developing.

Bone Graft

  • The type of bone graft used may affect the fusion.
  • For example, in cervical/neck spinal fusions, an autograft, which uses a small piece of bone from the patient’s body, has a higher success rate. (Verla T. et al., 2021)
  • Other graft options include specialized steel cages that fit between vertebrae and contain bone growth factors.
  • The surgeon recommends the optimal bone graft for the type of surgery, the number of vertebrae involved, and risk factors.

Risk Factors

  • The patient’s overall health and lifestyle impact the results of spinal fusion. Smoking increases the risk. (Berman D. et al., 2017)
  • Nicotine restricts blood circulation, decreases bone density, reduces new bone formation, and delays bone healing. (Hernigou J., & Schuind F., 2019)

The risk of pseudoarthrosis increases if the individual has any of the following: (Scoliosis Research Society, 2023)

  • Previous pseudoarthrosis
  • Obesity
  • Chronic steroid use
  • Malnutrition
  • Inflammatory diseases

Inflammatory conditions that can lead to bone loss and non-optimal bone healing include: (Torres H. M. et al., 2023)

  • Diabetes (Jiao H, Xiao E, & Graves DT, 2015)
  • Inflammatory bowel disease
  • Psoriasis
  • Rheumatoid arthritis
  • Chronic obstructive pulmonary disease/COPD
  • Periodontitis
  • Systemic lupus erythematosus/SLE

Symptoms

  • The primary sign of pseudoarthrosis is pain in the same area as before the fusion surgery.
  • If the bones pinch a spinal nerve, one arm may experience pain, tingling, burning, or numbness.
  • Rarely does a pinched nerve affect both arms.
  • The pain may return shortly after the procedure.
  • The pain may develop gradually or not appear for many months.
  • However, it’s more likely to appear after several months when the individual returns to their usual activities.

Diagnosis

  • The healthcare provider will learn about symptoms and perform a physical exam to evaluate the back.
  • They’ll assess mobility and the type of movement that causes pain.
  • Then, they order diagnostic imaging to see the spine and identify the cause of pain.
  • Individuals may need a CT scan, MRI, and/or X-rays to evaluate the spinal structures and instrumentation fully.

Treatment

Treatment for pseudoarthrosis will likely start with:

  • Physical therapy
  • Pain management – especially in cases where it is important to rule out other sources of back or neck pain.
  • Medication
  • Injections
  • If symptoms don’t improve with conservative care or if there is severe pain, the healthcare provider may recommend revision surgery.
  • Revision surgery is another procedure to treat complications or correct issues that arise after the initial pseudoarthrosis surgery.

Insights on Kyphosis & Treatment Approaches

Discover effective treatment approaches for kyphosis, its causes and symptoms while enhancing your posture today.

Introduction

How often do you catch yourself slouching after hours at a desk or scrolling through your phone? Do you experience persistent neck strain, shoulder tightness, or upper back discomfort? While many people recognize poor posture as an annoyance, few realize that long-term postural dysfunction can contribute to kyphosis—a spinal condition characterized by excessive forward curvature of the thoracic spine.

As a nurse practitioner with 20 years of experience in physical medicine and musculoskeletal health, I have seen firsthand how kyphosis affects both young and older adults, often leading to pain, mobility limitations, and even systemic complications. With a background that includes chiropractic care integration, I emphasize a multidisciplinary approach to kyphosis treatment, focusing on conservative therapies that address spinal alignment, muscle strength, and postural control.

This article explores the environmental causes of kyphosis, its impact on the musculoskeletal system, and evidence-based treatment strategies, including chiropractic adjustments, physical therapy, and postural rehabilitation.

What is Kyphosis? Understanding the Spinal Deformity

Kyphosis refers to an excessive anterior curvature of the thoracic spine, exceeding 40 degrees. While a mild thoracic curve is normal, excessive kyphosis can lead to visible postural changes, musculoskeletal pain, and even respiratory or gastrointestinal complications in severe cases.

Types of Kyphosis

There are several classifications of kyphosis, each with distinct causes:

  • Postural Kyphosis: The most common type, usually seen in adolescents and office workers, resulting from prolonged slouching and weak spinal musculature.
  • Scheuermann’s Kyphosis: A more rigid spinal deformity due to wedge-shaped vertebrae, typically diagnosed in teenagers.
  • Osteoporotic Kyphosis: Common in older adults due to vertebral compression fractures from osteoporosis.
  • Congenital Kyphosis: A rare condition present from birth due to abnormal vertebral development.

If left untreated, kyphosis can progressively worsen, leading to significant postural, neurological, and functional impairments.

Environmental Factors Contributing to Kyphosis

While genetic predisposition plays a role in kyphosis development, environmental and lifestyle factors significantly contribute to the condition. Understanding these risk factors can help with prevention and early intervention.

1. Poor Posture & Prolonged Sedentary Behavior

Chronic slouching, improper ergonomics, and excessive screen time encourage adaptive shortening of the anterior muscles (pectorals and upper abdominals) while weakening the posterior chain (erector spinae and scapular stabilizers). This imbalance reinforces thoracic kyphosis over time.

2. Sedentary Lifestyle & Weak Core Stability

A lack of functional movement and spinal stabilization exercises leads to postural instability, increasing the likelihood of kyphotic progression. A weak core and underactive back extensors contribute to poor spinal support, leading to excessive forward bending of the thoracic spine.

3. Heavy Backpacks & Improper Lifting Mechanics

In children and adolescents, carrying overweight backpacks can accelerate kyphotic posture by exerting excessive downward pressure on the spine. Similarly, incorrect lifting mechanics in adults (e.g., repetitive forward bending with poor lumbar support) increase spinal stress, contributing to degenerative kyphosis.

4. Osteoporosis & Age-Related Bone Loss

Older adults, particularly postmenopausal women, are at a higher risk of developing osteoporotic kyphosis due to decreased bone density. Compression fractures in the thoracic vertebrae can lead to irreversible spinal deformity, making early bone health management critical.

5. Spinal Injuries & Degenerative Disc Disease

Trauma, herniated discs, and chronic spinal degeneration can disrupt normal vertebral alignment, leading to structural kyphosis. Degenerative changes in the intervertebral discs contribute to spinal instability, loss of disc height, and increased forward curvature of the thoracic spine.

Symptoms & Effects of Kyphosis on the Musculoskeletal System

Kyphosis not only alters spinal alignment but also leads to cascading effects throughout the musculoskeletal system. Depending on severity, symptoms may range from mild discomfort to functional disability.

Common Symptoms of Kyphosis

–Upper Back Pain & Stiffness: Chronic discomfort, particularly between the shoulder blades and mid-thoracic region.
–Limited Mobility & Flexibility: A rigid thoracic spine reduces spinal extension, affecting overall movement.
–Neck & Shoulder Tension: Forward head posture and rounded shoulders cause excessive strain on the cervical spine, leading to cervicogenic headaches and referred pain.
–Muscle Fatigue & Weakness: Over time, kyphotic posture weakens the paraspinal muscles, reducing spinal endurance.
–Breathing & Digestive Issues: Severe kyphosis can compress the thoracic cavity, leading to restricted lung expansion and impaired digestion.

Neuromuscular Impact of Kyphosis

Cervical Involvement: Increased kyphotic curvature forces cervical hyperextension, straining the posterior neck muscles and contributing to occipital headaches, vertigo, and TMJ dysfunction.

Thoracic & Lumbar Impact: Kyphosis can trigger compensatory hyperlordosis in the lumbar spine, increasing stress on the lower back and contributing to disc degeneration and sciatic symptoms.

Biomechanical Dysfunction: Altered gait mechanics, hip instability, and reduced balance have been observed in patients with significant kyphotic curvature (Lorbergs et al., 2017).

Effective Treatment Approaches for Kyphosis

1. Chiropractic Care for Kyphosis Management

Chiropractic therapy is one of the most effective non-invasive treatments for managing kyphosis-related pain and improving spinal alignment. Research has shown that chiropractic spinal manipulation can improve mobility, reduce pain, and enhance postural stability (Norton et al., 2022).

Key Benefits of Chiropractic Adjustments:

1Spinal Realignment: Chiropractic adjustments restore normal vertebral positioning and reduce excessive thoracic curvature.
–Improved Postural Control: Chiropractic care strengthens postural awareness, spinal mobility, and core stability.
–Reduced Muscle Tension & Nerve Compression: Manual therapy alleviates trigger points, myofascial restrictions, and nerve impingements contributing to kyphotic discomfort.
 –Enhanced Flexibility & Range of Motion: Stretching techniques combined with spinal mobilization restore thoracic extension and shoulder mobility.

2. Physical Therapy & Postural Rehabilitation

Physical therapy plays a crucial role in strengthening the posterior chain, improving spinal stability, and reinforcing proper movement mechanics.

–Thoracic Extension Exercises (e.g., foam rolling, wall angels)
– Core Stabilization & Strength Training (e.g., dead bugs, planks)
– Scapular Retraction & Strengthening (e.g., rows, reverse flys)
–Cervical & Lumbar Postural Corrections

3. Bracing for Kyphosis Correction

In adolescents with Scheuermann’s kyphosis, bracing can help prevent worsening curvature during growth phases.

4. Postural Ergonomics & Lifestyle Modifications

– Ergonomic Workstations: Maintaining neutral spine alignment while sitting reduces kyphotic strain.
– Daily Mobility Exercises: Incorporating yoga, Pilates, or spinal decompression exercises can improve flexibility.
– Weight Management & Bone Health Optimization: Vitamin D, calcium supplementation, and weight-bearing exercises support spinal integrity.

Final Thoughts: Addressing Kyphosis Proactively

Kyphosis is a progressive condition that requires early intervention and a multidisciplinary treatment approach. By combining chiropractic adjustments, targeted physical therapy, and ergonomic modifications, patients can significantly reduce pain, improve posture, and enhance spinal function.
