Expert Spine Diagnosis and Treatment in Bellevue, WA

Your spine supports every movement you make. When neck, back, or nerve pain begins interfering with daily life, expert care is essential. Dr. Kenneth Nwosu, MD, MBA, provides advanced diagnostic evaluation and evidence-based treatments for a wide range of spine conditions, offering long-lasting relief and restored mobility for patients across Bellevue, Seattle, and Federal Way, Washington.

Cervical Conditions

Advanced Neck and Cervical Spine Treatment in Bellevue, WA

Neck pain is one of the most common spine complaints, often caused by age-related changes, injury, or poor posture. Dr. Kenneth Nwosu, MD, MBA, specializes in diagnosing and treating cervical (neck) spine conditions with precision and compassion. His goal is to restore mobility, relieve pain, and improve long-term quality of life using both conservative and minimally invasive techniques.

Cervical Arthropathy

Cervical arthropathy, or arthritis of the neck joints, causes stiffness, tenderness, and limited range of motion. It develops as the cartilage within the facet joints wears down over time. Dr. Nwosu uses diagnostic imaging and customized therapies such as medication, targeted rehabilitation, and image-guided injections to relieve inflammation and restore neck flexibility.

Cervical Radiculopathy and Herniated Disc

When a disc in the neck herniates and presses on surrounding nerves, it can lead to neck pain, tingling in the arms, and muscle weakness. Dr. Nwosu provides both non-surgical and minimally invasive treatments to decompress affected nerves and reduce pain while preserving spinal strength and flexibility.

Cervical Myelopathy

Cervical myelopathy occurs when spinal cord compression in the neck causes unsteady gait, hand weakness, or clumsy coordination. Prompt diagnosis is vital to prevent permanent nerve damage. Dr. Nwosu offers evidence-based surgical options to relieve pressure on the spinal cord and help restore control and stability.

Cervical Stenosis

Cervical stenosis narrows the spinal canal, compressing critical nerves and leading to pain or numbness in the neck, arms, or shoulders. Dr. Nwosu designs tailored decompression or minimally invasive surgical plans to relieve symptoms and restore spinal alignment.

Lumbar Conditions

Effective Lower Back Pain Solutions in Bellevue, Federal Way & Seattle

Lower back pain can affect anyone—whether from injury, poor posture, or natural aging. As a fellowship-trained spine surgeon, Dr. Nwosu provides comprehensive diagnosis and individualized treatments to help patients return to an active life. His approach emphasizes motion preservation, precision care, and targeted pain relief for all lumbar (lower back) conditions.

Annular Tear

An annular tear occurs when the outer layer of a lumbar disc tears, allowing fluid to leak out and irritate nearby nerves. This can cause deep lower back pain, sometimes radiating into the legs. Dr. Nwosu’s diagnostic expertise ensures accurate identification and personalized conservative or surgical treatment for recovery.

Bone Spurs

Bone spurs (osteophytes) develop as the spine responds to wear and tear. They can pinch nearby nerves and limit flexibility. Dr. Nwosu treats bone spurs using conservative care and advanced surgical techniques to restore comfort and spinal mobility.

Facet Joint Syndrome

Facet joint syndrome results from inflammation in the small joints that link the vertebrae. This often causes stiffness, pain during bending, or tenderness near the spine. Dr. Nwosu provides targeted therapies such as injections and minimally invasive procedures to reduce inflammation for long-term relief.

Failed Back Syndrome

Persistent pain after spine surgery is known as Failed Back Syndrome. Dr. Nwosu offers expert revision spine care, identifying the underlying issues and developing corrective plans for improved spinal health and better surgical outcomes.

Lumbar Disc Herniations

A lumbar disc herniation occurs when a disc slips or ruptures, pressing against nerves and causing shooting leg pain (sciatica). Dr. Nwosu’s treatments include guided therapy, epidural injections, and minimally invasive discectomy for effective nerve relief.

Lumbar Stenosis

Lumbar stenosis causes narrowing of the spinal canal in the lower back, leading to numbness, pain, or heaviness when walking. Dr. Nwosu performs decompression procedures designed to relieve nerve pressure and improve endurance and flexibility.

Lumbar Degenerative Disc Disease

With age or injury, spinal discs lose hydration and flexibility, causing chronic stiffness. Dr. Nwosu provides regenerative and structural treatments designed to preserve motion, reduce pain, and restore disc health where possible.

Lumbar Radiculopathy

Lumbar radiculopathy—commonly called sciatica—causes burning pain, tingling, or numbness down the leg. Dr. Nwosu uses precision diagnostic tools to identify the affected nerve and applies targeted therapies for lasting symptom relief.

Lumbar Spondylolisthesis

Spondylolisthesis happens when one vertebra slips forward over another, creating instability and nerve irritation. Dr. Nwosu offers stabilization and minimally invasive fusion treatments that correct alignment and alleviate pressure.

Spondylolysis (Pars Fracture)

This stress fracture in the spine’s small bony arch often affects athletes and active individuals. Early evaluation by Dr. Nwosu helps prevent worsening injury, and guided rehabilitation supports healing.

Spondylosis (Spinal Arthritis)

Spinal arthritis causes stiffness and chronic back pain due to joint inflammation and degeneration. Dr. Nwosu’s multidisciplinary approach focuses on pain control, core strengthening, and lifestyle modifications to sustain long-term relief.

SI Joint Pain

SI joint dysfunction causes pain in the lower back and hips, often due to uneven motion in the pelvis. Dr. Nwosu provides targeted therapy, injections, and stabilization procedures to realign and strengthen the SI joint.

Thoracic Conditions

Mid-Back Pain Care and Thoracic Spine Treatment in Bellevue, WA

The thoracic (mid-back) spine stabilizes your posture and connects the neck and lower back. Conditions in this region can cause discomfort, stiffness, or pressure on the spinal cord. Dr. Nwosu provides comprehensive thoracic spine evaluation and minimally invasive treatments to relieve pain while preserving function.

Thoracic Disc Herniations

A herniated disc in the mid-back can compress the spinal cord or nerves, resulting in pain, weakness, or discomfort around the chest or ribs. Dr. Nwosu applies advanced diagnostic imaging and tailored care plans to repair damage and restore balance.

Thoracic Stenosis

Thoracic stenosis is a narrowing of the spinal canal in the mid-back. It can affect mobility or cause back and leg pain. Dr. Nwosu uses advanced, minimally invasive decompression to alleviate nerve pressure and restore movement.

Thoracic Myelopathy

When spinal cord compression develops in the thoracic spine, patients may experience balance problems, weakness, or coordination loss. Dr. Nwosu’s specialized expertise in minimally invasive thoracic procedures ensures safe decompression and neurological preservation.

Client Testimonials

Dr. Nwosu did surgery on my back October 26th. By the time I met him, I had already seen two other surgeons, and had a bad experience with both. I was emotional because nobody was helping me. By the time I met Dr. Nwosu I couldn't even walk. Dr. Nwosu was kind and patient with me from the very first time I met him. He has always allowed enough time to answer all of my questions at every appointment. He has never been rude or judgemental, always compassionate. My surgery was very successful!

Was very friendly. Well informed in his explaniations,as to procedure reguarding surgery. Excellent followup after surgery.."

I’m 3 months post op from c5-c6 disc replacement and I am now pain free. Dr. Nwosu was transparent with expected outcomes from the surgery. The surgery fixed the nerve pain and issues that I was having before. I will say that months 1-3 following surgery has highs and lows as with any surgery, but now it’s going well and I have almost full mobility back that I hadn’t had for nearly 6 months before surgery. Regarding trying to reach on call providers, that wasn’t an issue and you just need to follow the call prompts given in your post op instructions. I highly recommend him. His PA is also wonderful and helpful in answering any questions that may arise.

I’m writing this review for those of you wondering if you should be seen by Dr. Nwosu. The answer is absolutely yes! There are good doctors out there and there are exceptional doctors/surgeons such as Dr. Nwosu. I know this firsthand working in the OR room during his cases as a X-Ray tech. He’s very thorough, compassionate and detailed…. His surgical cases go very well. I was recently in a MVA and choose tone seen by Dr Nwosu because he is Exceptional!
