Adult spinal deformities

Types of Adult Spinal Deformities

Degenerative Scoliosis

Degenerative scoliosis is one of the most common adult spinal deformities. It occurs when age-related degeneration of spinal discs and joints causes the spine to curve abnormally. This condition commonly affects the lumbar spine and may result in back pain, leg pain, spinal stenosis, and imbalance.

Patients may notice gradual leaning to one side, uneven posture, or increasing difficulty standing upright for prolonged periods.

Kyphosis

Kyphosis refers to excessive forward curvature of the spine, leading to a hunched posture. Severe kyphosis may place strain on muscles, affect balance, and reduce quality of life.

In some patients, kyphosis develops due to osteoporosis, vertebral fractures, degenerative changes, or previous spinal surgery.

Sagittal Imbalance

Sagittal imbalance occurs when the spine loses proper front-to-back alignment. Patients often struggle to stand upright comfortably and may lean forward while walking.

This condition can cause severe fatigue, muscle strain, and reduced mobility because the body must constantly compensate to maintain balance.

Adult Progression of Childhood Scoliosis

Some adults with scoliosis diagnosed during adolescence may experience progression of spinal curvature later in life. Curves may worsen gradually with age, particularly when associated with degeneration or osteoporosis.

Common Symptoms of Adult Spinal Deformity

Symptoms vary depending on the type and severity of the deformity. Some patients experience mild discomfort, while others develop severe pain and neurological symptoms.

Common symptoms include:

• Chronic back pain
• Neck pain
• Leg pain or sciatica
• Numbness or tingling
• Weakness in the arms or legs
• Difficulty standing upright
• Reduced walking tolerance
• Postural imbalance
• Fatigue during standing or walking
• Visible spinal curvature
• Loss of height
• Difficulty performing daily activities

In advanced cases, nerve compression may lead to worsening neurological symptoms affecting mobility, coordination, and bladder or bowel function.

Causes and Risk Factors

Several factors may contribute to adult spinal deformity.

Common causes include:

• Degenerative disc disease
• Facet joint arthritis
• Osteoporosis
• Previous spinal surgery
• Spinal fractures
• Neuromuscular disorders
• Congenital spinal abnormalities
• Progression of adolescent scoliosis
• Age-related spinal degeneration

As spinal discs lose height and joints degenerate, the spine may gradually lose stability and alignment, resulting in abnormal curvature and imbalance.

How Adult Spinal Deformity Is Diagnosed

Accurate diagnosis requires comprehensive clinical assessment and detailed spinal imaging.

Evaluation may include:

• Medical history assessment
• Neurological examination
• Standing spinal X-rays
• MRI scans
• CT imaging
• Assessment of spinal balance and alignment
• Bone density evaluation

Modern spinal imaging allows detailed analysis of spinal curvature, nerve compression, sagittal balance, and overall spinal mechanics.

Understanding the relationship between spinal alignment and symptoms is essential when planning treatment.

Non-Surgical Treatment Options

Many patients with adult spinal deformity can initially be managed without surgery.

Conservative treatment options may include:

• Physiotherapy
• Core strengthening exercises
• Pain management
• Anti-inflammatory medication
• Image-guided spinal injections
• Postural rehabilitation
• Osteoporosis treatment
• Lifestyle modification

Non-surgical treatment aims to reduce pain, improve function, and slow progression of symptoms.

However, patients with severe deformity, progressive neurological symptoms, or major spinal imbalance may eventually require surgical treatment.

Surgical Treatment for Adult Spinal Deformity

Surgery may be considered when symptoms significantly affect quality of life or when conservative treatment fails to provide adequate relief.

Surgical goals may include:

• Relieving nerve compression
• Correcting spinal alignment
• Restoring spinal balance
• Stabilising the spine
• Reducing pain
• Improving mobility and function

Decompression Surgery

Spinal decompression may be performed to relieve pressure on nerves or the spinal cord caused by stenosis or deformity-related compression.

Spinal Fusion

Fusion surgery stabilises the spine using screws, rods, cages, and bone grafts. This may help restore alignment and prevent progression of deformity.

Minimally Invasive Techniques

Modern minimally invasive spinal surgery techniques may reduce muscle disruption, blood loss, pain, and recovery time in selected patients.

Robotic-Assisted Spinal Surgery

Robotic spinal surgery allows enhanced precision during instrumentation placement and complex spinal reconstruction procedures.

Advanced surgical technologies continue to improve safety and outcomes for patients with adult spinal deformity.

The Importance of Specialist Assessment

Adult spinal deformity is highly complex and requires specialist evaluation by experienced spinal surgeons.

Treatment decisions depend on multiple factors including:

• Severity of deformity
• Neurological symptoms
• Spinal balance
• Overall health
• Bone quality
• Mobility goals
• Previous spinal surgery

Careful preoperative planning and individualised treatment strategies are essential to achieving optimal outcomes.
