Cubital tunnel syndrome is a common compressive neuropathy of the upper limb. Surgical decompression is indicated for patients who failed conservative therapy. Decompression in situ has shown to achieve comparable outcomes as decompression with anterior transposition in idiopathic cubital tunnel syndrome. Endoscopic cubital tunnel decompression has gained popularity in recent years, as surgeons can attain decompression of the ulnar nerve along its course using a small incision. Results from randomised controlled studies and systematic reviews, comparing endoscopic with open decompression in situ, are promising. Cases in which anterior transposition of the ulnar nerve is needed, an endoscopic technique can still be used by creating an additional volar portal, for the mobilisation of ulnar nerve. Early short-term results are encouraging. Further adequately powered, prospective, preferably double-blinded, randomised study are needed.
