Cubital tunnel syndrome
Cubital tunnel syndrome is characterized by numbness and/or tingling in the small and ring fingers of your hand, usually with elbow flexion. It is frequent at night and likely associated with elbow position while sleeping. Other common causes include talking on the phone, driving, and reading. It can be separated from carpal tunnel syndrome by location in the hand -ring/small fingers vs thumb/index/middle fingers for carpal tunnel. Other causes can include a pinched nerve in the neck (radiculopathy) and thoracic outlet syndrome, but these are less common. Usually cubital tunnel is present if elbow flexion causes symtoms. Treatment involves avoiding elbow hyperflexion by using a headset or Bluetooth when on the the phone, lowering keyboard height when typing, moving the driver's seat back from the steering wheel while driving, and holding books at a greater distance. When sleeping, placing an elbow pad in the front of the elbow to prevent flexion, or wrap the elbow with a towel. Lastly, avoiding vibration can be helpful, such as power tools and bike riding. If symptoms progress, a nerve conduction/EMG study should be ordered and performed by a reputable physician. Depending on the result, a variety of surgical options include: simple cubital release, subcutaneous ulnar nerve transposition, and submuscular ulnar nerve transposition, among others. The surgical options should be discussed with Dr. Lewis or your physician to choose the best option for you. For appointments call 925-939-8585 |
