Fingertip injury symptoms?

summary

Each skeletal muscle of human body is divided into two parts: muscle belly and tendon. Muscle belly is composed of muscle fibers, with soft red color and contractility. Tendon is composed of dense connective tissue, with hard white color and no contractility. Tendon rupture may occur after trauma or excessive force. After rupture, there will be pain, swelling and limited finger movement. If not treated in time, tendon adhesion may occur, finger dysfunction may even affect later life. Fingers are divided into flexor and extensor tendons, extensor tendon rupture ratio is larger, so how to do after the finger tendon rupture? Let's talk about it.

Fingertip injury symptoms?

Surgical treatment: if the extensor tendon rupture, the general extensor tendon insertion rupture for stab injury, distal interphalangeal joint suddenly flexion and avulsion of extensor tendon attachment point, local cutting injury can also be cut. Mallet finger deformity and avulsion fracture were found in some patients. If it is flexor tendon rupture, the patient is generally even in a state of rupture. The first choice for the treatment of tendon rupture is surgery, incision and tendon anastomosis, which is the basis of treatment. Anti inflammatory treatment was given after operation.

Plaster external fixation: when the extensor tendon of the finger is broken, the finger is placed in the hyperextension of the distal interphalangeal joint and the flexion position of the proximal interphalangeal joint to relax the extensor tendon, and fixed with plaster or aluminum plate for 4-6 weeks. If the flexor tendon was broken, the fingers were flexed, plaster external fixation was performed for 4-6 weeks, and functional exercise was performed after removing the plaster.

Function exercise: after plaster fixation, the tendon function exercise: bend the wrist joint 30 degrees, try to make a fist in place, then stretch the metacarpophalangeal joint and bend the metacarpophalangeal joint under the condition of keeping the interphalangeal joint flexion, try to reach the normal position every time, don't be afraid of pain, you can use the other hand to help, don't be violent, try to be soft and continuous.

matters needing attention

It is normal that there will be obvious swelling of the hand at the beginning of exercise after plaster external fixation. At night, the affected limb was raised 45 degrees to help the swelling subside. The swelling usually disappears in the morning. Go on with a new round of exercise. Physical therapy is often very effective. The key is to maintain balance.
