What Can I Expect from Trigger Finger Surgery?

Trigger means surgery, which is suitable for non-surgical treatment of patients who are ineffective or advanced cases, and nodules are formed in local tendons.

Tendons and tenosynovitis occur due to the long muscle tendon being fixed in the fibrous bone sheath, the sharp edge of the proximal or distal tendon sheath and the repeated sliding of the tendon and long-term strong friction, resulting in local pain or due to the compression of the tendon. Dysfunction is stenosing tenosynovitis. Clinically common are radial styloid stenosing tenosynovitis (DeQuervain disease) and finger flexor tenosynovitis (trigger finger).

The long abductor hallucis longus and short extensor hallucis tendons pass through the shallow sulcus of the radial styloid process to form a bone fiber sheath tube. The tendon and bony sheath tube form an angle at the radial styloid process. When the thumb and wrist move, this folded angle increases Larger, which increases the friction between the tendon and the wall of the tube, and tenosynovitis can occur over time.

The flexor tendon of the hand has a tendon sheath that bundles it on the metacarpal head and the phalanx to prevent the flexor tendon from ejecting towards the palm and sliding on both sides when flexing the fingers. Annular ligament. The flexor tendon rubs against the annular ligament when the fingers are forced, and both can cause chronic injuries during long-term hard hands, causing tendon sheaths, tendon edema, hyperplasia, and adhesion. As the fibrous sheath is congested and the edema is also significantly thickened, the bone fibrous sheath is narrowed and compresses the tendon. The tendon can be nodular or gourd-shaped and prevent the tendon from sliding. When the enlarged tendon cannot pass through the narrow sheath, the function of tendon flexion is lost.

The disease is mostly related to acute and chronic injuries. Radial styloid stenosis tenosynovitis is most common in middle-aged and elderly women. It is painful when the hand is exerted, especially when the hallucis longus and short extensor muscles are moved. There is limited tenderness at the intersection of the radial styloid process and tendon and the tendon can be touched Nodules, Finkelsteinsign (+). Flicking fingers and thumbs affected fingers have popping sounds, tenderness at the palmar striae of the far side, and tender nodules at the metacarpal head. When the baby narrows the thumb, it shows the flexion of the terminal segment of the thumb, which cannot be actively straightened. The nodule can be touched at the entrance of the tendon sheath of the thumb, and it is often mistaken for dislocation of the thumb or congenital malformation.

Surgery related anatomy.

Trigger finger surgery is suitable for:

1. Non-surgical treatment failure.

2. In advanced cases, nodules are formed in local tendons.

Local or brachial plexus block, children can use general anesthesia, lying on their backs, with the affected limb extended and placed on a small operating table, surgery can be performed under a tourniquet.

1. Make a small horizontal incision or L-shaped incision at the entrance of the tendon sheath of the affected finger, that is, at the distal palm transverse line. The incision of the thumb is transverse to the thumb.

2. After exposing the skin and subcutaneously, bluntly separate and expose the flexor tendon sheath, find the entrance of the tendon sheath, use a small vascular forceps to lift the tendon sheath from the entrance and cut it open, until the tendon is completely loosened.

3. Flick your finger or thumb, or use a hook knife to pick and release. Surgery can be performed under local anesthesia. A small incision is made in the palmar striatum at the far side of the palm, and then it is inserted into the entrance of the tendon sheath with a hook knife.

1. Untie all the narrow tendon sheaths.

2. Don't damage the bilateral finger nerve blood vessels, especially the thumb radial finger nerve across the flexor tendon sheath, but also pull it to the sides. Be careful not to damage the superficial branch of the radial nerve when the tendon sheath is cut at the radial styloid process.

1. Patients can be encouraged to perform finger flexion and extension activities.

2. Properly raise the affected limb and remove the stitches 7 to 10 days.
