Abstract: Herein, we report a case of a 49-year-old man with a history of bilateral hemiplegia caused by severe traumatic brain injury. During his stay in the convalescent rehabilitation hospital, he developed a flexion deformity of the 4th and 5th fingers of his right hand. Elbow palpation and ultrasonography showed that the ulnar nerve was dislocated from the elbow canal, and a nerve conduction study revealed that the conduction velocity was low in the right elbow. Thus, a diagnosis of cubital tunnel syndrome was made and an ulnar nerve transfer was performed to prevent progression. Prior to onset, an over-table had been used by the patient for daily activities such as sitting, training, and eating. Therefore, it was considered that the repeated use of the over-table plausibly exerted pressure on the dislocated ulnar nerve, leading to the onset of the cubital tunnel syndrome.As over-tables and wheelchair armrests are often used during rehabilitation, it is imperative to pay attention to elbow compression when using them in patients with ulnar nerve dislocation.
