Definition & Terminology
Formal Definition
### Formal Medical Definition
Guyon's canal syndrome is defined as compression neuropathy of the ulnar nerve at the wrist, occurring in the Guyon's canal (ulnar tunnel). This results in sensory changes in the ring and little fingers and/or motor weakness in the intrinsic hand muscles innervated by the ulnar nerve.
### Etymology & Word Origin
Named after French anatomist Jean Casimir Guyon (1831-1920). The canal is also called the "ulnar tunnel."
### Types
- Zone 1: Motor + sensory
- Zone 2: Motor only
- Zone 3: Sensory only

Etymology & Origins
Named after French anatomist Jean Casimir Guyon (1831-1920). The canal is also called the "ulnar tunnel."
Anatomy & Body Systems
Ulnar Nerve Path
- Brachial plexus (C8-T1)
- Through Guyon's canal at wrist
- To hand intrinsic muscles
- Sensory to ring/little finger
Guyon's Canal Boundaries
- Pisiform bone (medial)
- Hamate bone (lateral)
- Palmar carpal ligament (roof)
- Flexor retinaculum
Types & Classifications
By Zone Affected
- Zone 1: Both motor and sensory
- Zone 2: Motor only (most common)
- Zone 3: Sensory only
By Cause
- Compression (cyst, tumor)
- Trauma
- Repetitive stress
- Cycling/occupational
Causes & Root Factors
Primary Causes
- Cyclist's handlebar pressure
- Cysts or tumors
- Repetitive hand/wrist motion
- Trauma/fractures
- Anatomical variations
Risk Factors
- Cycling
- Motorcycle riding
- Weightlifting
- Occupational (hammering)
- Cysts/ganglia
Signs & Characteristics
Symptoms
Sensory:
- Numbness in ring/little finger
- Tingling
- Pain (sometimes)
Motor:
- Weak grip
- Difficulty with fine motor
- Clumsiness
Conventional Treatments

- May be permanent if delayed
FAQ
What is the difference between cubital tunnel and Guyon's canal?
Cubital tunnel is compression at the elbow; Guyon's canal is compression at the wrist.
Can cycling cause permanent damage?
With early treatment, most recover fully. Prolonged compression can cause permanent weakness.
