Lacertus fibrosus surgery (median nerve compression at the elbow)

This compression can cause:

• a loss of strength in the hand (difficulty pinching or grasping objects),
• rapid fatigue in the upper limb,
• occasional tingling in the fingers,
• clumsiness when performing fine motor tasks.

The operation is carried out via a small incision on the front of the elbow. The surgeon locates the median nerve and then cuts through the lacertus fibrosus to relieve the compression.

The surgery is most often carried out on an outpatient basis under local anaesthesia.

After the procedure

• The arm can be used again fairly quickly for everyday activities.
• Pain is generally moderate.
• The stitches are removed or absorbed within 10 to 15 days.
• Strength is regained gradually over a period of several weeks to several months, depending on how long the compression has lasted.

Expected outcomes

The main aim is to restore the function of the median nerve by improving the strength, endurance and precision of hand movements. The earlier the compression is treated, the better the chances of a full recovery.
