Cervical postsurgical spondylolisthesis is a condition in which, following cervical spine surgery (such as laminectomy or corpectomy), one vertebra slides forward (anterolisthesis) or backward (retrolisthesis) relative to the adjacent vertebra. This misalignment arises from surgical destabilization—removal of bony or ligamentous support—or from failure of the fusion or instrumentation intended to stabilize the spine. Over time, the abnormal movement can compress nerve roots or the spinal cord, leading to pain, neurologic deficits, and reduced quality of life PubMedPubMed.
Anatomy
Structure & Location
The cervical spine comprises seven stacked vertebrae (C1–C7) between the base of the skull and the thoracic spine. Each vertebra consists of:
A vertebral body anteriorly, which bears weight.
A vertebral arch posteriorly, forming the vertebral foramen through which the spinal cord passes.
Facet joints at the back that guide movement.
Intervertebral discs between bodies that absorb shock Cleveland Clinic.
Origin & Insertion
Although bones do not “originate” or “insert,” the cervical vertebrae serve as attachment sites for muscles. One key muscle is the sternocleidomastoid, which originates from the manubrium (breastbone) and clavicle, and inserts on the mastoid process behind the ear. This muscle rotates and flexes the head Cleveland ClinicWikipedia.
Blood Supply
Vertebral arteries ascend through foramina in C1–C6 to supply the brainstem and posterior brain Cleveland Clinic.
Ascending cervical and deep cervical arteries (branches of the thyrocervical trunk) supply vertebral bodies, muscles, and posterior elements OHSU.
Nerve Supply
Eight pairs of cervical spinal nerves exit above C1–C7 (C8 exits below C7).
Dorsal rami supply the posterior elements and overlying muscles; ventral rami form the brachial plexus for upper extremity motor/sensory function NCBI.
Key Functions
Head support: Carries the 10–13 lb head.
Range of motion: Allows flexion, extension, lateral bending, and rotation.
Protection: Encloses the spinal cord in a bony canal.
Shock absorption: Intervertebral discs cushion loads.
Neurovascular passage: Provides safe channels for arteries, veins, nerves.
Muscle attachment: Anchors muscles for posture and movement Cleveland ClinicTeachMeAnatomy.
Each of these roles explains why postsurgical disruption can lead to instability and slippage.
Types
Spondylolisthesis is classified by etiology into six main types; in the cervical spine, the relevant categories are:
Degenerative (age-related joint wear)
Isthmic (pars interarticularis defect)
Traumatic (acute fracture)
Pathologic (infection or tumor)
Dysplastic (congenital anomaly)
Post-surgical/iatrogenic (surgery-related destabilization) Wikipedia.
Within the post-surgical category, slippage may follow procedures that remove stabilizing elements, such as corpectomy or extensive laminectomy, or from instrumentation/fusion failure.

Gentle surgical technique preserving facets
Use of appropriate instrumentation
Avoid over-distraction of levels
Restore normal cervical lordosis
Postoperative cervical bracing

Frequently Asked Questions
What makes it “postsurgical”?
It follows surgery that removes stabilizing tissue, allowing vertebral slip.How soon after surgery can it develop?
From weeks to years, often as hardware loosens or adjacent segments degenerate.Is it common?
Rare—reported in ~14% of multilevel laminectomies, but clinically significant slips are fewer PubMed.Can conservative care fix it?
Mild slips may improve with bracing, PT, and pain management.When is revision surgery needed?
Neurologic decline, severe pain, or high-grade slip unresponsive to non-surgical care.What are revision options?
Posterior fusion, extension of previous fusion, or combined approaches.Will hardware always hold?
Most constructs are durable, but patient factors (e.g., osteoporosis) can lead to loosening.Are there non-surgical stabilizers?
Cervical collars/halo vests can provide temporary support.Can this cause myelopathy?
Yes—cord compression from slippage may lead to myelopathic signs.Is “failed neck surgery syndrome” the same?
Postsurgical spondylolisthesis is one cause of persistent symptoms in failed surgery cases.How is bone healing enhanced?
By anabolic agents (teriparatide) and ensuring good nutrition and vitamin D.Are minimally invasive techniques possible?
In select cases, endoscopic approaches can address instability.Does age matter?
Older patients with poor bone quality have higher slip risk.Can exercise harm me?
High-impact activities should be avoided; gentle PT is encouraged.What is the long-term outlook?
With timely treatment, many return to daily activities with minimal disability.
