The major nerves that traverse the elbow are the ulnar, median, and radial nerves, along with their branches.
Nerves Around the Elbow
Here's a more detailed look at these nerves:
-
Ulnar Nerve: This nerve is particularly susceptible to compression at the elbow, leading to cubital tunnel syndrome.
- Cubital Tunnel Syndrome: This condition can cause pain, paresthesia (numbness or tingling), and weakness in the hand and fingers.
-
Median Nerve: The median nerve passes through the elbow and innervates muscles in the forearm and hand.
-
Radial Nerve: The radial nerve and its branches supply muscles in the arm and forearm, and it is also responsible for sensation in part of the hand.
| Nerve | Function | Potential Issues at the Elbow |
|---|---|---|
| Ulnar | Supplies muscles in the forearm and hand; sensation in the hand. | Cubital tunnel syndrome (compression at the elbow). |
| Median | Supplies muscles in the forearm and hand; sensation in the hand. | Compression is possible, but less common than with the ulnar. |
| Radial | Supplies muscles in the arm and forearm; sensation in the hand. | Radial tunnel syndrome (compression in the forearm). |
