This article presents a case of ulnar nerve compression at the Guyon's canal caused by a true aneurysm of the ulnar artery secondary to blunt trauma. The duration of follow-up was one year.
Setting:
Hospitalized care. A 27-year-old man who worked in an office fell on to a gravel path landing on his out-stretched right hand. Decompression of the ulnar nerve was made by simple ligation of the damaged artery and resection of aneurysm.
Measures:
Histological examination. The sensory symptoms disappeared two days after the operation. At one year after surgery, the patient was completely asymptomatic. There was no residual cold intolerance. Simple ligation of the damaged artery and resection of aneurysm resulted satisfactory. It seemed to be a safe method in this case. Ulnar nerve compression due to a true aneurysm of the ulnar artery in the Guyon's canal is rarely described in the literature.
