Cervical Cord Fixation Single Level

Single-Level Cervical Cord Fixation — most commonly performed as Anterior Cervical Discectomy and Fusion (ACDF) — is the most frequently performed cervical spine surgery, addressing disc herniation, cervical spondylotic myelopathy, or instability at a single cervical level through a small anterior neck incision. The diseased disc or compressive bone spur is removed under microscopic vision, a precisely sized interbody cage filled with bone graft is placed between the two vertebral bodies, and an anterior titanium plate with screws provides immediate stability while bony fusion consolidates over 3 to 6 months. ACDF reliably decompresses the neural structures and stabilises the affected level in a single procedure through a well-tolerated anterior approach.

Types of Single-Level Cervical Fixation

Single-level cervical fixation can be performed through anterior or posterior approaches depending on the location of compression and the presence of instability.

• ACDF — Anterior Cervical Discectomy and Fusion (most common — anterior approach with cage and plate)
• Posterior Cervical Laminoforaminotomy with Fixation (posterior approach for foraminal stenosis)
• Cervical Disc Arthroplasty (motion-preserving artificial disc replacement — alternative to fusion)
• ACCF — Anterior Cervical Corpectomy and Fusion (vertebral body removal for multi-level disease from a single approach)
• Posterior Cervical Fixation Single Level (for posterior instability without anterior decompression need)

Risk Factors of Cervical Disc Disease

Cervical disc disease causing myelopathy or radiculopathy develops through a combination of degenerative, occupational, and constitutional factors.

• Degenerative cervical disc disease causing progressive loss of disc height and osteophyte formation
• Cervical spondylosis with facet joint arthritis narrowing the neural foramina
• Acute cervical disc herniation from sudden lifting, jerking, or trauma
• Congenital cervical canal stenosis reducing the safety margin against cord compression
• Occupational repetitive neck flexion and extension in certain professions
• Previous neck trauma or whiplash injury accelerating cervical degeneration

Cervical Cord and Nerve Root Compression Symptoms

Cervical myelopathy and radiculopathy produce characteristic symptoms that should prompt urgent neurological or neurosurgical evaluation to prevent permanent spinal cord damage.

• Arm pain, numbness, or tingling radiating from the neck in a specific nerve root distribution
• Neck pain with stiffness and reduced range of motion
• Hand clumsiness — difficulty buttoning clothes, writing, or fine motor tasks
• Balance difficulty and unsteady wide-based gait from cervical myelopathy
• Electric shock sensation down the spine with neck flexion (Lhermitte's sign)
• Bilateral hand weakness or leg weakness and spasticity
• Urinary urgency or hesitancy from spinal cord dysfunction
• Dropping objects unexpectedly from weakened or numb hands
