Dr. Baron Lonner is an adult spinal deformity specialist orthopedic spine surgeon with offices in NYC (Manhattan) and Long Island (Great Neck).
Adult spinal deformity (ASD) is a broad term used to describe abnormal alignment or curvature of the spine that develops or progresses after skeletal maturity. These conditions can cause chronic back pain, nerve compression, difficulty standing upright, impaired mobility, and a significant decline in quality of life.
At Scoliosis & Spine Associates, Dr. Baron Lonner provides advanced evaluation and treatment for adults with spinal deformities ranging from mild scoliosis to complex multi-planar spinal imbalance. As one of the best scoliosis surgeons in NYC and a nationally recognized orthopedic spine surgeon in New York, Dr. Lonner specializes in personalized treatment plans that prioritize pain relief, spinal balance, improved function, and long-term outcomes.
Whether treatment involves physical therapy, injections, minimally invasive procedures, or complex reconstructive spine surgery, every patient receives an individualized care plan designed around their goals.
I had a fantastic experience during my recent visit to see Dr. Lonner. He was kind, professional and most importantly he fully listened as I went over my condition, an area I feel many NYC spine surgeons are lacking in. He performed a full examination and explained himself every step of the way. Once it was decided that surgery would be the next step, he went over every detail of the process and took the time to address any concerns I had. I will be moving forward with the surgery, and cannot recommend Dr Lonner enough!
Update: 4 months post-op, flawless experience. Run do not walk to this surgeon. Thank YOU Dr. Lonner!!! ~ Google
What Is Adult Spinal Deformity?
Adult spinal deformity refers to abnormal curvature or malalignment of the spine in patients over the age of 18. Unlike adolescent scoliosis, adult deformities are often accompanied by arthritis, degenerative disc disease, spinal stenosis, osteoporosis, and loss of normal spinal balance.
Adult spinal deformity includes a wide range of conditions, including:
- Adult idiopathic scoliosis
- Adult degenerative scoliosis (de novo scoliosis)
- Kyphosis (excessive forward curvature)
- Flatback syndrome
- Degenerative spondylolisthesis
- Post-traumatic spinal deformity
- Post-surgical spinal deformity
- Coronal imbalance
- Sagittal imbalance
Many of these conditions gradually worsen over time, making early evaluation by an experienced adult spinal deformity specialist in Manhattan important for preserving mobility and quality of life.
Common Causes of Adult Spinal Deformity
Adult spinal deformities may develop from several underlying conditions, including:
- Age-related disc degeneration
- Osteoarthritis of the spine
- Osteoporosis
- Vertebral compression fractures
- Untreated adolescent scoliosis
- Congenital spinal abnormalities
- Previous spine surgery
- Trauma
- Neuromuscular disorders
As these conditions progress, the spine may lose its normal alignment, causing pain, muscle fatigue, nerve compression, and difficulty maintaining an upright posture.
Symptoms of Adult Spinal Deformity
Symptoms vary depending on the type and severity of the deformity.
Patients commonly experience:
- Chronic neck or back pain
- Pain radiating into the buttocks or legs
- Numbness or tingling
- Muscle weakness
- Difficulty standing upright
- Forward stooping posture
- Leaning to one side
- Loss of height
- Fatigue with walking
- Difficulty walking long distances
- Poor balance
- Visible spinal curvature
- Uneven shoulders or hips
Some patients also notice that everyday activities such as shopping, cooking, or traveling become increasingly difficult due to pain and spinal imbalance.

Successful treatment begins with a comprehensive evaluation.
Your consultation includes:
Medical History
We evaluate:
- Pain history
- Functional limitations
- Previous spine treatments
- Medical conditions
- Bone health
- Activity level
- Personal treatment goals
- Physical Examination
Evaluation includes:
- Posture
- Walking pattern
- Balance
- Range of motion
- Neurological function
- Muscle strength
- Reflexes
- Flexibility
- Advanced Imaging
Diagnostic testing may include:
- Standing full-length spinal X-rays
- Cobb angle measurements
- MRI
- CT scans
- Flexion-extension X-rays
- Bone density testing
- EOS imaging when appropriate
These studies allow accurate assessment of spinal alignment in both the coronal and sagittal planes, helping determine the most effective treatment strategy.
Non-Surgical Treatment Options
Many adults achieve significant symptom relief without surgery.
Treatment plans may include:
Physical Therapy
A customized rehabilitation program focuses on:
- Core strengthening
- Flexibility
- Balance training
- Gait improvement
- Postural correction
- Endurance
- Pain Management
Depending on symptoms, treatment may include:
- Anti-inflammatory medications
- Muscle relaxants
- Prescription pain medications
- Neuropathic pain medications
- Epidural Steroid Injections
For patients with nerve compression or spinal stenosis, image-guided injections may reduce inflammation and improve mobility.
Lifestyle Modification
Healthy habits can help reduce symptoms, including:
- Regular exercise
- Weight management
- Smoking cessation
- Proper lifting techniques
- Low-impact aerobic conditioning
- Osteoporosis Management
Bone health is especially important in adults with spinal deformity. When appropriate, treatment may include bone density evaluation and medications to improve bone strength before surgery.
When Is Surgery Recommended?
Surgery is considered when conservative treatment no longer provides adequate relief or when spinal deformity significantly limits daily life.
Common indications include:
- Persistent disabling pain
- Progressive scoliosis
- Severe spinal imbalance
- Difficulty standing upright
- Progressive neurological symptoms
- Significant leg pain from nerve compression
- Loss of independence
- Declining quality of life
Treatment recommendations are based on symptoms, function, overall health, and individual goals—not simply the degree of spinal curvature.
Advanced Adult Spinal Deformity Surgery in NYC
As one of the best orthopedic spine surgeons in New York, Dr. Baron Lonner performs advanced reconstructive procedures for even the most complex adult spinal deformities.

Osteotomies
Specialized procedures that allow correction of rigid spinal deformities by carefully reshaping portions of the spine.
Revision Spine Surgery
Correction of failed prior spine surgery, implant complications, or progressive deformity.

Modern technology, including computer-assisted planning, neuromonitoring, and advanced instrumentation, allows for safer procedures and more predictable outcomes in appropriately selected patients.
Recovery After Adult Spine Surgery
Recovery depends on the complexity of the procedure and the patient’s overall health.
Most patients experience gradual improvement in:
- Pain levels
- Walking tolerance
- Posture
- Balance
- Daily function

Does every adult spinal deformity require surgery?
No. Many patients achieve excellent symptom relief through physical therapy, medications, injections, and lifestyle modifications. Surgery is reserved for patients with significant pain, neurological symptoms, progressive deformity, or loss of function.
Can spinal deformity worsen over time?
Yes. Many adult spinal deformities are progressive, particularly those associated with arthritis, osteoporosis, or degenerative disc disease. Early evaluation can help identify appropriate treatment before the condition becomes more severe.
Is recovery from adult spinal deformity surgery successful?
Advances in surgical techniques, imaging, and perioperative care have significantly improved outcomes. Most appropriately selected patients experience meaningful improvements in pain, posture, mobility, and quality of life.
