Supination and pronation, impairment of:

Supination and pronation are the two movements that allow us to rotate our forearm and wrist, enabling us to perform a variety of daily activities such as turning doorknobs, using tools, and playing sports. Impairment of these movements can cause significant functional limitations and affect one's quality of life. 


Types of procedures involved:

  • Physical therapy: exercises to improve strength and mobility of the forearm and wrist.
  • Splinting or casting: to immobilize the affected area to promote healing and prevent further injury.
  • Surgery: to repair or replace damaged bones, joints, or soft tissue.
  • Nerve conduction studies electromyography (EMG) to evaluate nerve function.


The causes of impairment of supination and pronation include:

  • Fractures or injuries to the bones or joints of the forearm, elbow, or wrist.
  • Nerve damage or compression can affect the ability to control the forearm and wrist muscles.
  • Tendinitis or other soft tissue injuries.
  • Arthritis or other degenerative joint conditions.


The signs and symptoms of impairment are:

  • Difficulty rotating the forearm and wrist.
  • Pain, swelling, and tenderness in the affected area.
  • Stiffness or reduced range of motion.
  • Weakness or numbness in the forearm or hand.


  • Physical examination: to assess the extent of the injury and the condition of the forearm, elbow, and wrist.
  • Imaging tests, such as X-rays, CT scans, or MRI, evaluate the extent of the damage to the bones, joints, or soft tissue.
  • Nerve conduction studies or electromyography (EMG) evaluate nerve function and identify any nerve damage or compression.
  • Blood tests to rule out underlying medical conditions that may have caused the impairment.

Note: In all the forearm and wrist injuries, codes 5205 through 5213, multiple impaired finger movements due to tendon tie-up, muscle or nerve injury, are to be separately rated and combined not to exceed rating for loss of use of hand.
