Immediate Return to Daily Activities

Specific Instrument for Each Problem


Spirecut develops two different types of surgical instruments, which are called sono-instruments®, to achieve percutaneous carpal tunnel releases. Patients can go back to their daily activities on the next day. 

Carpal Tunnel

Are you suffering from carpal tunnel syndrome? You are not alone! It is frequent: one person out of ten will suffer from carpal tunnel syndrome in their lifetimes. It is frequent in women between 40 and 60 years old and sometimes affects men and younger age groups. Conditions such as diabetes increase patients’ chances of carpal tunnel syndrome. It can also occur during pregnancies and usually disappears spontaneously after delivery.

What is it?

The carpal tunnel is a narrow osteo-fibrous passageway in the wrist containing nine flexor tendons and the median nerve. Under overuse conditions (repetitive hand activities), the tissue surrounding the flexor tendons thickens causes a mechanical compression on the median nerve. It results in pain, numbness, and tingling in the hand and arm, particularly at night for carpal tunnel syndrome. The disease is frequently bilateral (affecting both hands).

Carpal tunnel syndrome is painful, prevents sleep at night, and aggravates over time, causing long-term irreversible sensory and motor nerve damage. Early diagnosis and treatment are essential.


Health professionals recommend non-operative treatment in early cases, such as wearing a night splint or keeping the wrist neutral. Nerve gliding exercises may also help.

Most carpal tunnel syndromes require surgical decompression to give the medium nerve more space. The incision is 4-5cm long. After the surgery, the night pain usually disappears, but the healing of the surgical wound takes time, preventing an early return to daily activities and work. Many patients also complain of a transient decrease in grip strength and pain at the base of the wrist, called “pilar pain”, lasting months or sometimes years. Other complications also occur. Some are severe (i.e. infection, inadvertent lesion to a branch of the median nerve, CRPS, a syndrome of chronic severe pain in the whole hand).

Trigger Finger

The adult trigger finger  is a disease characterised by a painful blockade of the finger inflexion. Affected patients cannot straighten their fingers without the help of the other hand.

In milder forms, patients feel pain in  the palm, at the finger’s base, or dorsally at the proximal interphalangeal joint. In the severe stage, patient cannot fully straighten their fingers, even passively. The ring finger and thumb are most frequently concerned by trigger fingers.

The combination of trigger fingers and carpal tunnel syndromes is relatively frequent. Sometimes several fingers are affected simultaneously – or at different moments of the patient’s life. People with diabetes are particularly affected.


Many patients conditions improve with corticosteroid injections, but the affection tends to recur after the infiltration. Recurrences are the reasons trigger fingers require surgery.

Although it is successful in most patients, there are possible complications after the surgery: surgical scars can be painful. Certain patients can also present serious complications (infection, lesion of a digital nerve). After the surgery, most patients cannot return to their daily and operational activities for two or more weeks.

SPIRECUT commercialises sono-instruments® to treat carpal tunnel syndrome and trigger fingers.
