Extensor tendon injuries




de la 1500 RON


The hand is a complex organ with an equally complex anatomy that helps us perform a wide variety of activities. At the level of the hand, in addition to the rest of the anatomical elements (vessels, nerves, bones, muscles, soft parts), we also find the tendons which are those white fibrous bands that connect the muscles to the bone. There are two types of tendons: the flexors located on the volar face of the hand and forearm, respectively, the extensors located on the back of the hand and forearm.

Extensor tendon injuries can occur on several levels:

• zone 1 or distal interphalangeal joint

• zone 2 or at the level of the middle phalanx

• zone 3 or the proximal interphalangeal joint

• zone 4 or at the level of the proximal phalanx

• zone 5 or metacarpophalangeal joint

• zone 6 or at the level of the metacarpals

• zone 7 or radiocarpal joint

• zone 8 or distal third forearm

• area 9 or forearm middle and proximal third

Causes of tendon injuries

Extensor tendon injuries can be complete or partial. The most common causes that can cause a rupture of an extensor tendon are:

• cuts with various objects (knife, glass, tin or other sharp objects)

• crush injuries, hitting

• animal / human bites

• certain sports

Treatment of extensor tendon injuries

At the time of the consultation, the patient will be carefully examined and depending on what lesions he presents, the treatment options will be discussed and whether these lesions can be resolved with local anesthesia or require another type of anesthesia.

Surgical treatment involves wounding the wound, identifying the ends of the sectioned tendon (proximal and distal end) and tendon suture (tenorafia), suturing the skin wound and splinting for at least 3 weeks depending on the level of the lesion.

Postoperative recommendations

• avoidance of local traumas

the removal of the sutures will take 14 days

• early hand mobilization

• following a physiokinetotherapy program

• suppression of immobilization after 3-4 weeks

• maintaining the affected segment in elevation to decrease postoperative edema
