Cubital tunnel syndrome
Cubital tunnel syndrome is the second most common nerve compression in the arm, after carpal tunnel. It comes from pressure on the ulnar nerve as it passes behind the elbow, and it can be unsettling, but there is a clear path to managing it.
What it is
The ulnar nerve runs behind the inner side of the elbow, through a space called the cubital tunnel. When it is compressed or stretched there, it can cause tingling and numbness in the little and ring fingers, and over time, weakness of the hand. {{CONFIRM with Holly}}
What you might notice
- Tingling or numbness in the little and ring fingers, often when the elbow is bent (on the phone, or asleep).
- A weakening grip, or difficulty with fine tasks.
- Aching around the inner elbow.
How it is treated
As ever, we begin with the least intervention that will help.
- Activity and posture changes, and sometimes a night splint to keep the elbow from bending fully. {{CONFIRM with Holly}}
- Surgery to release or reposition the nerve, considered when symptoms persist or the nerve is significantly affected. It is usually a day case. {{CONFIRM with Holly: decompression vs transposition.}}
Recovery & what to expect
- A careful assessment, including whether nerve studies would help. {{CONFIRM with Holly}}
- A plan that starts simply, before any operation is considered.
- The procedure, if needed, usually as a day case. {{CONFIRM with Holly}}
- Healing and hand therapy to restore comfort and function.
