Spine Surgery — Find Specialists & Top Hospitals Worldwide | MyMedicPlus

Spine surgery is a subspecialty of both orthopaedic surgery and neurosurgery that focuses on the surgical diagnosis and treatment of disorders of the spinal column — including the vertebral bones, intervertebral discs, spinal cord, nerve roots, and surrounding supporting structures such as ligaments and facet joints. Spine surgeons manage the full spectrum of spinal pathology, from degenerative disc disease causing neck and back pain to traumatic spinal fractures and complex spinal deformity requiring multi-level reconstruction.

The spinal column has two primary functions: it provides structural support for the body and protects the delicate spinal cord and exiting nerve roots from injury. Disorders that compromise either function — through compression, instability, deformity, or trauma — may result in pain, neurological deficits, and disability. Spine surgery aims to decompress the nervous system, restore spinal stability and alignment, and relieve pain to improve quality of life.

Importantly, the vast majority of spinal pain does not require surgery. Most acute episodes of neck or back pain resolve with conservative management including physiotherapy, anti-inflammatory medications, and activity modification. Surgery is reserved for a carefully selected minority of patients in whom structural pathology is clearly identified on imaging, symptoms correlate with the anatomical finding, and conservative treatment has been adequately trialled without sufficient improvement — or in whom neurological compromise makes urgent surgical intervention necessary.

Spine surgeons come from two training backgrounds: orthopaedic surgeons who subspecialise in spine, and neurosurgeons who focus on spinal pathology. Both perform similar procedures for degenerative disc disease and deformity, while neurosurgical spine surgeons may additionally manage intraspinal tumours and tethered cord syndrome.

Spine surgeons evaluate and surgically manage an extensive range of spinal conditions:

• Lumbar disc herniation: Rupture of the intervertebral disc's outer annulus allowing the gel-like nucleus pulposus to compress an exiting nerve root, causing radiculopathy (sciatica) with radiating leg pain, numbness, and potentially weakness.
• Cervical disc herniation: Disc material compressing cervical nerve roots causing arm pain, numbness, and weakness (cervical radiculopathy), or — in severe cases — compressing the spinal cord itself (myelopathy).
• Lumbar spinal stenosis: Degenerative narrowing of the spinal canal compressing multiple nerve roots, causing neurogenic claudication (bilateral leg pain and heaviness that worsens with walking and is relieved by sitting).
• Cervical myelopathy: Progressive spinal cord compression from disc disease, ligament ossification, or spondylosis causing gait unsteadiness, hand clumsiness, and upper and lower motor neurone signs — the most common cause of spinal cord dysfunction in adults over 55.
• Spondylolisthesis: Slippage of one vertebra forward or backward on the one below, causing back pain and possible nerve compression; grade III or IV spondylolisthesis with symptoms typically requires surgical stabilisation.
• Scoliosis: Abnormal lateral curvature of the spine exceeding 10 degrees on X-ray; adolescent idiopathic scoliosis curves above 45–50 degrees and adult degenerative scoliosis causing functional impairment may require surgical correction and fusion.
• Spinal fractures: Vertebral fractures from trauma (vehicle collision, fall) or from osteoporosis (osteoporotic vertebral compression fractures); neurologically unstable or painful fractures require surgical stabilisation or augmentation.
• Spinal tumours: Primary and metastatic tumours involving the vertebral body, epidural space, intradural extramedullary compartment, or intramedullary spinal cord, requiring surgical decompression, stabilisation, and tumour sampling.
• Spinal infections: Including vertebral osteomyelitis and epidural abscess causing back pain, fever, and potentially neurological deficits requiring surgical drainage and long-term antibiotics.
• Degenerative disc disease: Accelerated disc degeneration with loss of disc height, end-plate changes, and vertebral instability causing discogenic back pain at one or two motion segments.

Spine surgeons perform a broad range of open and minimally invasive procedures across the cervical, thoracic, and lumbar spine:

• Microdiscectomy: Minimally invasive removal of herniated lumbar disc material using an operating microscope and a small incision, with minimal muscle disruption; provides rapid relief of sciatica in carefully selected patients.
• Anterior cervical discectomy and fusion (ACDF): Removal of a diseased cervical disc through an anterior neck incision, with decompression of the nerve root or spinal cord and fusion of the adjacent vertebrae using an interbody cage and anterior plate.
• Laminectomy: Removal of the lamina (roof of the spinal canal) over one or more vertebral levels to decompress the spinal cord or nerve roots in lumbar or cervical stenosis.
• Posterior lumbar interbody fusion (PLIF) and transforaminal lumbar interbody fusion (TLIF): Spinal fusion procedures inserting an interbody cage between adjacent vertebrae from a posterior approach, combined with pedicle screw fixation, for spondylolisthesis, degenerative disc disease, or post-decompression instability.
• Lateral lumbar interbody fusion (LLIF/XLIF): Accessing the lumbar disc through the lateral flank with the patient on their side, avoiding posterior muscle disruption while restoring disc height and allowing indirect neural decompression.
• Vertebroplasty and kyphoplasty: Injection of bone cement (PMMA) into a collapsed osteoporotic vertebral body, with or without balloon inflation to restore height (kyphoplasty), providing rapid pain relief for painful osteoporotic vertebral fractures.
• Cervical disc arthroplasty (artificial disc replacement): Replacing a diseased cervical disc with a motion-preserving prosthetic disc, preserving range of motion at the treated level and potentially reducing adjacent segment degeneration.
• Minimally invasive spine surgery (MIS): Using tubular retractors, fluoroscopic or endoscopic guidance, and small incisions to perform discectomy, laminectomy, or fusion with reduced muscle damage, blood loss, and recovery time compared with traditional open surgery.
• Scoliosis correction with instrumented fusion: Multi-level posterior spinal fusion using pedicle screws and rods to correct scoliotic curvature and maintain correction, performed in adolescents and adults with progressive or symptomatic scoliosis.
• Spinal cord stimulation (SCS) trial and implant: Implanting epidural electrodes delivering electrical stimulation to modulate pain signals for failed back surgery syndrome and complex regional pain syndrome.

Spine surgery consultation is warranted in the following situations, ranging from elective to emergency:

• Cauda equina syndrome: New bowel or bladder dysfunction (urinary retention, incontinence), bilateral leg weakness, and saddle anaesthesia in the setting of lumbar disc pathology constitutes a surgical emergency requiring evaluation within hours. Delay beyond 24–48 hours risks permanent incontinence and paralysis.
• Progressive neurological deficit: Worsening leg or arm weakness, advancing hand clumsiness, or gait deterioration due to cervical myelopathy or nerve root compression requires urgent spine surgery assessment — progressive deficits rarely recover without decompression.
• Radiculopathy not responding to conservative management: Leg pain (sciatica) or arm pain from disc herniation that has not improved after six to twelve weeks of physiotherapy, analgesics, and an epidural steroid injection warrants surgical consultation.
• Neurogenic claudication from spinal stenosis: Bilateral leg pain, heaviness, and numbness that limits walking to one to two blocks despite conservative treatment should be evaluated for lumbar decompression surgery.
• Spinal instability or significant deformity: Spondylolisthesis with progressive slip, scoliosis exceeding 45 to 50 degrees, or severe kyphotic deformity causing postural imbalance warrant spine surgery assessment for stabilisation.
• Confirmed spinal infection or tumour: An epidural abscess causing neurological compromise or a vertebral tumour causing instability requires urgent spine surgery consultation for decompression and stabilisation.

Spine surgeons come from two distinct training pathways: orthopaedic surgery and neurosurgery. Orthopaedic spine surgeons complete a four-year medical degree (MD or DO), a five-year orthopaedic surgery residency, and a one- to two-year spine fellowship at an accredited spine training programme. Neurosurgical spine surgeons complete a four-year medical degree, a seven-year neurosurgery residency, and optionally a spine subspecialty fellowship.

Spine fellowships provide intensive training in complex cervical, thoracic, and lumbar degenerative surgery, adult spinal deformity correction, minimally invasive spine techniques, spinal oncology and trauma, and endoscopic approaches. Fellows perform high volumes of index procedures under subspecialty supervision and develop independent operative skills for the full range of spinal procedures.

Board certification for orthopaedic spine surgeons is awarded by the American Board of Orthopaedic Surgery (ABOS), and for neurosurgical spine surgeons by the American Board of Neurological Surgery (ABNS). Both may additionally hold fellowship certification from the Society of Lateral Access Surgery (SOLAS), North American Spine Society (NASS), or Scoliosis Research Society (SRS). In the UK, spine surgeons hold FRCS (Tr & Orth) or FRCS (SN) credentials. Ongoing surgical audit and outcome reporting are expected as the evidence base for spinal procedures continues to evolve.

Referrals to a spine surgeon typically come from neurologists, rheumatologists, pain physicians, or your GP based on clinical symptoms and imaging findings. Before seeing a spine surgeon, ensure you have had appropriate MRI imaging of the relevant spinal region and that a trial of conservative management — typically six to twelve weeks of physiotherapy, anti-inflammatory medications, and possible epidural steroid injections — has been completed, unless neurological emergency dictates otherwise.

At your spine surgery consultation, bring all MRI and CT scans on digital disc along with the radiology reports, a timeline of your symptoms and their impact on daily function, a list of all prior treatments including physiotherapy and injections, and any prior surgical records. Ask your surgeon how many times per year they perform the specific procedure being considered, whether minimally invasive options are available for your condition, what the expected recovery timeline and rehabilitation requirements are, and what the surgical risks are in your specific case. Second opinions for complex or multi-level fusion procedures are entirely appropriate and often encouraged.
