Ultrasound-guided Release of the Median Nerve at the Elbow in Patients With Lacertus Syndrome

Lacertus syndrome is an orthopaedic condition that occurs when the median nerve is compressed where it passes under the lacertus fibrosus. Treatment for lacertus syndrome is generally aimed at relieving compression of the median nerve and reducing associated symptoms. Treatment options vary according to the severity of the condition and the patient's individual needs. Sectioning the Lacertus fibrosus frees the median nerve. It is performed as an outpatient procedure under local anaesthetic, and the patient can resume his or her activities immediately. Lacertus fibrosus section has been described as an open procedure, i.e. with a horizontal scar in the elbow crease. Ultrasound guided surgery is an innovative technique that has proved its effectiveness for nerve releases such as the median nerve in the carpal tunnel or the ulnar nerve in the elbow. This technique was tested on a series
