Decompression of Peripheral Nerves
Ulnar Nerve – Compression of the ulnar nerve cubital tunnel posterior to the medial edge of the humerous is the second most common nerve compression. Cubital tunnel syndrome (otherwise known as ulnar sulcus syndrome) is a compression syndrome of the ulnar nerve, involving a constriction of the ulnar sulcus—caused by heavy lifting, tennis player’s elbow, pitcher’s elbow, etc. This may result in neuronal damage and a wide range of neuronal dysfunctions. Cases of advanced damage to the ulnar nerve may lead to impairment of motor functions—ultimately resulting in claw hand.
Various therapeutic treatments have been available such as nerve decompression without transposition, nerve decompression with subcutaneous transposition of the nerve in a ventral direction (ventral transposition), and transposition of the nerve in a ventral direction into the muscle (submuscular transposition).
Endoscopically assisted decompression of the ulnar nerve offers a new option involving a small incision being made in the skin in order to release the proximal and distal constrictions of the nerve without having to make an incision of the same length in the skin. The advantage of this endoscopic technique is that a much smaller incision can be used while at the same time extending the length of neurolysis. This leads to less morbidity, rapid improvement of the symptoms, and fast rehabilitation compared with conventional procedures.
