What is Radial Neuropathy?

Radial neuropathy most commonly develops as a result of compression of the radial nerve in the spiral groove around the humerus. The classical picture seen in those who sleep for a long time with their arm resting on a surface is called 'Saturday night palsy'.

Due to involvement of the nerve, marked weakness occurs in lifting the wrist and fingers ('wrist drop'). Sensory loss may also accompany on the back of the hand and the area of the thumb.

Clinical examination and electrophysiological evaluation are decisive in diagnosis. Most cases improve within several weeks or months with conservative treatment; surgery may be necessary in some severe traumatic cases.

Symptoms

Inability to lift the wrist and fingers (wrist drop)
Numbness on the back of the hand
Sensory loss at the base of the thumb
Decreased grip strength
Pain or tenderness on the outer-posterior aspect of the arm
Triceps muscle weakness (in proximal lesions)
Impairment of fine hand movements

Risk Factors

Use of crutches (axillary compression)
Holding the arm in a fixed position for long periods
Humeral fractures
Deep sleep after alcohol consumption (Saturday night palsy)
Wrist and elbow trauma
Tight watch strap or arm band
Repetitive forearm movements

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • If you cannot lift your wrist
  • If sudden weakness develops in the arm
  • If sensory-motor loss occurs after trauma
  • If complaints do not improve within weeks
  • If hand use limits daily life

Treatment Methods

01
Static wrist splint (for wrist drop)
02
Physiotherapy and joint range of motion exercises
03
Removal of the compressive factor
04
Pain control (NSAIDs, neuropathic agents)
05
Vitamin B complex support
06
