C7–T1 radiculopathy occurs when the nerve roots at the cervicothoracic junction (the transition between the neck’s C7 vertebra and the upper back’s T1 vertebra) become irritated or compressed. This can lead to pain, numbness, weakness, and other symptoms radiating into the arm and hand.
Anatomy
Structure & Location
The C7–T1 spinal motion segment lies where the flexible cervical spine (neck) meets the more rigid thoracic spine (upper back). It consists of:
Vertebrae: the seventh cervical vertebra (C7) and first thoracic vertebra (T1).
Intervertebral disc: cushioning fibrocartilage between C7 and T1.
Facet joints: small joints on the back that guide motion.
Intervertebral foramen: openings where the C7 and T1 nerve roots exit. Spine-healthMedscape
Origin & “Insertion” (Pathway)
Origin: Nerve roots arise from the spinal cord segments for C7 and T1 inside the spinal canal.
Pathway (“Insertion”): After leaving the canal through the foramina, these nerves travel down the arm:
C7 root supplies triceps and wrist extensor muscles, plus sensation to the middle finger.
T1 root supplies hand intrinsic muscles and sensation to the inner forearm. Cleveland Clinic
Blood Supply
Small radicular arteries branch off segmental arteries, entering each foramen to supply the nerve roots and the corresponding spinal cord segment. NCBIWikipedia
Nerve Supply
Each spinal nerve splits into a ventral (motor) root and dorsal (sensory) root before merging. The dorsal root carries sensory signals from the arm, and the ventral root carries motor signals to muscles. Wikipedia
Key Functions
Arm extension: C7 controls triceps for straightening the elbow.
Wrist extension: C7 helps lift the back of the hand.
Finger extension: C7 extends the fingers at the knuckles.
Fine hand movements: T1 powers intrinsic hand muscles for dexterity.
Sensation to middle finger: C7 provides feeling along the middle finger.
Sensation to inner forearm: T1 provides feeling along the inner forearm. Cleveland Clinic
Types of Radiculopathy
Radiculopathy at C7–T1 can be classified by cause, duration, and severity:
Compressional (mechanical) vs. inflammatory
Acute (sudden) vs. chronic (long-standing)
Unilateral (one side) vs. bilateral (both sides)
Mild (intermittent symptoms) vs. severe (constant, disabling)
Traumatic (injury-related) vs. degenerative (wear-and-tear)
Causes
Herniated C6–C7 or C7–T1 disc pressing on the root.
Bone spurs (osteophytes) from arthritis.
Degenerative disc disease thinning the disc.

FAQs
What is radiculopathy?
Radiculopathy means irritation or compression of a spinal nerve root, causing pain, numbness, or weakness along its pathway.Why does C7–T1 radiculopathy occur?
Most often from a herniated disc or bone spur pressing on the nerve as it exits the spine.How is it diagnosed?
With a physical exam (Spurling’s test) and imaging (MRI, CT) plus nerve studies (EMG).Can it heal on its own?
Many cases improve over 6–12 weeks with non-surgical care.What exercises help?
Gentle cervical stretches, scapular strengthening, and posture training.Are injections useful?
Yes—cervical epidural steroid injections can reduce inflammation around the nerve.When is surgery needed?
If there’s severe weakness, progressive symptoms, or no improvement after 3 months.What is ACDF?
Anterior cervical discectomy and fusion removes the disc and fuses the vertebrae to decompress the nerve.Will I lose neck motion after fusion?
Fusion reduces motion at that level but patients adapt, and the pain relief often outweighs the loss.Is physical therapy painful?
Good therapists tailor exercises to avoid aggravating pain, so therapy should not be overly painful.Can radiculopathy recur?
Yes—maintaining posture, exercise, and ergonomic habits reduces risk.What lifestyle changes help?
Ergonomic workstations, regular breaks, smoking cessation, weight management.Are alternative therapies effective?
Acupuncture, yoga, and mindfulness can complement medical treatments for pain relief.How long until I can work?
Light desk work may resume in days; heavy lifting or overhead work may require weeks to months.Can children get this?
Rarely, but congenital spinal conditions or injury can cause radiculopathy in youngsters.
