Wrist drop caused by radial nerve palsy can be cured in the majority of cases with conservative treatment.

Wrist drop is a symptom of radial nerve palsy in which the wrist hangs limply and the patient is unable to lift it.

Radial nerve palsy is a result of compression of the radial nerve, which is the nerve that travels down the arm and helps with movement of the arm, wrist, hand, and fingers and its compression causes pain, weakness and loss of function in a person’s arm, wrist, hand, and fingers.

Treatment for wrist drop and radial nerve palsy often depends on the cause. In some cases, the wrist drop may go away over time as awkward positions are corrected, injuries heal, or cysts or tumors are removed. 

Wrist drop caused by radial nerve palsy can be cured in the majority of cases. About 70% of radial nerve palsy cases are cured with conservative treatment. 

Treatment for wrist drop and radial nerve palsy may include: 

  • Medication
    • Anti-inflammatories
    • Pain medicines
  • Physical therapy to strengthen muscles and increase range of motion
  • Splint or cast
  • Transcutaneous Electrical Nerve Stimulation (TENS)
  • Surgery

Depending on the amount of damage to the radial nerve, it can take weeks to months for a nerve to heal after treatment.

  • Dislocations 
  • Pressure injuries caused by repetitive motion or remaining in awkward body positions for long periods of time, such as while working or sleeping
  • Bruises that put pressure on the radial nerve
  • Growths such as tumors or cysts
