Cervical spondylolytic anterolisthesis is a condition in which a cervical vertebra (one of the bones in the neck) slips forward over the vertebra below it because of a defect or fracture in its pars interarticularis (the small bony bridge between the upper and lower facets). This forward slip can pinch nerves or the spinal cord, leading to pain, stiffness, and neurological symptoms. Cleveland ClinicWikipedia
Anatomy
Structure & Location
Vertebral Body: Cylindrical front part of each cervical vertebra (C3–C7).
Pars Interarticularis: Bony bridge between the superior and inferior articular facets; common site of stress fractures.
Facet Joints: Paired joints at the back of vertebrae help guide motion.
Intervertebral Discs: Cushion between bodies, allowing movement and shock absorption.
Cervical spondylolytic anterolisthesis most often occurs at C6–C7 due to high mechanical stress in this segment. Mayo ClinicWikipedia
Blood Supply
Vertebral Arteries: Run through transverse foramina of C1–C6, supplying the vertebrae and spinal cord.
Ascending Cervical Arteries: Branches of the thyrocervical trunk supply muscles and bone. Mayo Clinic
Nerve Supply
Cervical Spinal Nerve Roots (C1–C8): Exit above corresponding vertebrae (except C8 exits below C7) to supply skin, muscles, and ligaments.
Recurrent Meningeal (Sinuvertebral) Nerves: Innervate the disc, ligaments, and facet joints. Mayo Clinic
Functions (6)
Head Support: Holds the skull upright.
Flexion/Extension: Nodding the head.
Lateral Flexion: Tilting head side to side.
Rotation: Turning head left and right.
Protection: Shields the spinal cord and nerve roots.
Shock Absorption: Discs and facet joints distribute load during movement. Cleveland Clinic
Types
Isthmic (Spondylolytic) Anterolisthesis: Due to pars interarticularis defect.
Degenerative Anterolisthesis: From facet arthritis and disc degeneration.
Traumatic Anterolisthesis: Caused by acute fractures in posterior elements.
Pathologic Anterolisthesis: From bone diseases (infection, tumor).
Congenital (Dysplastic) Anterolisthesis: Developmental malformation of facets.
Post-surgical (Iatrogenic): Complication of prior cervical spine surgery. Wikipedia

Frequently Asked Questions
What is the difference between spondylolysis and spondylolisthesis?
Spondylolysis is a fracture or defect in the pars interarticularis; spondylolisthesis occurs when that defect allows the vertebra to slip forward. OrthoInfoCan cervical spondylolytic anterolisthesis heal on its own?
Low-grade slips may stabilize with conservative care, but true healing of a pars defect is rare in adults. NCBIIs surgery always required?
No. Most patients improve with non-surgical treatments unless there is severe instability or neurological compromise. Mayo ClinicHow long is recovery after ACDF?
Typically 4–6 weeks for initial healing, with full fusion taking 3–6 months. Mayo ClinicCan this condition cause headaches?
Yes, nerve irritation and muscle tension in the neck can trigger tension-type headaches. precisionhealth.com.auAre braces effective?
Soft collars may relieve pain short-term, but prolonged use can weaken neck muscles. Mayo ClinicIs physical therapy safe?
Yes, under guidance it is a cornerstone of non-surgical management. PhysioPediaWhat lifestyle changes help most?
Posture correction, ergonomic workstations, and regular exercise. Mayo ClinicCan yoga help?
Gentle yoga can improve flexibility and strength but avoid extreme neck positions. PhysioPediaHow is instability measured?
Flexion-extension X-rays measure vertebral translation (>4 mm) or angulation (>10°). WikipediaDoes this increase my risk of spinal cord injury?
Slightly, especially if the slip is high-grade or with trauma. Mayo ClinicCan children outgrow isthmic slips?
Stress fractures can heal if diagnosed early; adult slips rarely reverse. WikipediaAre there exercises to avoid?
Heavy neck extension, high-impact sports, and sustained upward gazing. PhysioPediaIs it hereditary?
A family history of pars defects can increase risk but most cases are acquired. OrthoInfoWhat is the long-term outlook?
With proper management, most maintain good function; severe cases may require surgery. Cleveland ClinicMayo Clinic
