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

RecruitingNA

Sponsor: GCS Ramsay Santé pour l'Enseignement et la Recherche

Conditions: Median Nerve Entrapment

Interventions: Elbow ultrasound-guided surgery

Countries: France

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 of 18 cadavers and then on a series of 15 patients with a lacertus syndrome. The patients underwent the operation without any immediate surgical or anaesthetic complications. Muscle strength returned immediately and persisted. Pain was reduced and all patients who were working were able to carry out their professional activities from the very first week. The millimetric skin incision healed without hypertrophic scar tissue. A small haematoma appeared at week 1 and resolved spontaneously. No other late complications were observed. In this context, this study would consolidate the preliminary results observed and confirm the hypothesis that minimally invasive percutaneous surgery under ultrasound is appropriate for sectioning Lacertus fibrosus safely, rapidly and effectively in Lacertus syndrome.
