HAND
Open carpal tunnel surgery
Carpal tunnel syndrome is caused by compression of the median nerve at the wrist. This compression can cause tingling, numbness in the fingers, night-time pain and, in some cases, a loss of strength in the hand.
The procedure involves cutting the ligament that is compressing the nerve in order to relieve the pressure. It is carried out on an outpatient basis under local or regional anaesthesia.
The technique used involves open surgery via a small incision in the palm of the hand. This method is the most widely practised standard technique. It allows direct visualisation of the median nerve and the surrounding anatomical structures, ensuring complete and safe release of the carpal tunnel. The long-term results are excellent and comparable to those of endoscopic surgery.
After the operation, night-time pain and tingling often improve rapidly. However, recovery is gradual and requires a period of convalescence.
It is common to experience tenderness at the scar site or discomfort in the palm for several weeks. A temporary reduction in grip strength is also common. Regaining strength may take several weeks or even a few months, depending on the activities carried out.
Improvement in sensation depends on how long the nerve has been compressed and the severity of the compression. Where the nerve has been compressed for a long time, recovery may be slow and take several months. In some cases, particularly where there is long-standing nerve damage, a full recovery of sensation is not always possible.
Simple daily activities can usually be resumed quickly after the procedure. However, manual work, DIY, gardening or sports that place heavy strain on the hand often require a longer recovery period (6 to 12 weeks).
The aim of the operation is to halt the progression of nerve compression, relieve symptoms and allow the median nerve to recover gradually.
