1 – What are the reasons why a release of de Quervain tenosynovitis is required?
What is a a Tenosynovitis of Tenosynovitis :
This is an irritation of the sheath enveloping the thumb’s two tendons (abductor longus and extensor pollicis brevis), which travel through a tunnel at the base of the thumb. This inflammatory process begins following manual activity or impact, and is maintained by the friction of the tendons as they pass through the tunnel. This leads to inflammation of the whole area, sometimes accompanied by sensitization of the nerve (sensitive branch of the radial nerve) or cyst formation at the end of the tunnel.
Why is intervention necessary?
Initially, other non-surgical therapeutic approaches may be considered:
- Use of a splint
- Administration of anti-inflammatory treatments
- Physiotherapy with physiotherapy
- Infiltration practice
If these methods fail to produce the desired results, or if the condition is particularly severe, surgical intervention is recommended.
What additional additional tests are necessary ?
Diagnosis is essentially a clinical examination of the patient.
X-rays, ultrasound scans of the tendons and even MRI scans can sometimes be useful.
2 – The derorlement de l’intervention
The procedure is usually performed under local or regional anaesthetic on an outpatient basis. The operation involves a small incision to open the sheath or tunnel surrounding the two tendons. The aim is to reduce the friction and inflammation that cause pain. In some situations, it may also be necessary to free the sensitive branch of the radial nerve in the event of irritation, or to remove a cyst if one has developed. As with any surgical procedure, certain events can disrupt the optimal course of the operation. The surgeon may decide at the last minute to cancel the operation in case of doubt (uncertainty as to the side to be operated on, uncertainty as to the equipment or sterilization, or even doubt as to the patient’s identity).
What are the typical consequences of surgery?
In general, mobilization of the fingers and wrist can be undertaken immediately. However, the surgeon may consider temporary splinting in cases of significant inflammation. Re-education may sometimes be useful, although self-education is often sufficient.
What can we expect from this surgery?
This surgery has proved effective in relieving pain. Thumb and wrist function is usually restored within a few weeks.
