Ulnar nerve compression can occur at five different sites within the body. The first site is at the wrist, where the ulnar nerve can be compressed as it passes through a tunnel of ligaments and bones. This condition is known as Guyon’s canal syndrome. The second site is at the elbow, where the ulnar nerve passes behind the medial epicondyle of the humerus. Compression at this site can result in cubital tunnel syndrome. The third site is in the forearm, where the ulnar nerve can be compressed as it passes between the two heads of the flexor carpi ulnaris muscle. This condition is known as the arcade of Struthers syndrome. The fourth site is in the upper arm, where the ulnar nerve can be compressed as it passes through the medial intermuscular septum. Lastly, the fifth site is in the shoulder region, where the ulnar nerve can be compressed as it passes through the axilla. Ulnar nerve compression at any of these sites can lead to symptoms such as numbness, tingling, weakness, and pain in the hand, wrist, and forearm. Proper diagnosis and treatment are necessary to alleviate the symptoms and prevent further complications.
How do you approach the ulnar nerve decompression?
It is performed under local, regional or general anaesthetic. If you have open ulnar nerve decompression surgery, a 3-4 inch incision is made along the elbow, revealing the ulnar nerve. The orthopaedic surgeon then examines the nerve and removes any tissue that is causing compression.
What are the restrictions for cubital tunnel release?
Avoid using the hand on your operative side and lifting objects heavier than one to two pounds until your first post-operative appointment, approximately two weeks after your procedure. When you can return to work is dependent upon the type of work you do. Please ask your surgeon for specific work restrictions.
What are the approaches for cubital tunnel release?
– In-situ decompression.
– Simple decompression.
– Anterior subcutaneous transposition.
– Anterior submuscular transposition.
– Medial epicondylectomy.
– Endoscopic cubital tunnel release.
