Symptoms of tendon injury, symptoms of tendon injury in the hand

Tendon injuries are generally caused by external forces. Excessive muscle fatigue and long-term poor posture causing muscle imbalance can all lead to tendon injuries. After tendon injury, related joint movements will be impaired. Pay attention to early treatment and formulate a reasonable treatment plan.

1. Symptoms and Signs

After the tendon ruptures, the corresponding joints lose their mobility. For example, if the deep flexor tendon of the digitorum is ruptured, the distal interphalangeal joint cannot flex; if both the deep and superficial flexor tendons of the digitorum are ruptured, both the distal and proximal interphalangeal joints cannot flex.

When the extensor tendon is ruptured at different parts, the corresponding joint cannot be stretched and may become deformed. Sometimes the tendon is not completely ruptured, and although the joint can still move, it will be weak and painful when undergoing a resistance test.

2. Early treatment

1. Careful examination: To formulate an optimal surgical plan depends on careful examination before and during the operation, which is related to the success and effect of the operation. Such as confirming the time interval between the injury and the surgery, the area of ​​tendon rupture, the number of ruptures, the degree of wound contamination, whether there is an unstable fracture and the degree of tissue damage around it, etc. Only then can it be determined whether the tendon should be treated early and what the treatment method should be. Usually, wounds that are less than 12 hours old, have a lesser degree of contamination, are neater incisions, and have smaller tendon defects should be sutured early and closed in the first place. The normal structure and stability of bones and wound coverage are prerequisites for early tendon repair.

2. Debridement: Early and thorough debridement is the key to directly affecting prognosis. The purpose is to remove necrotic tissue contamination and foreign matter, turning contaminated wounds into clean wounds. It can also further help understand the damage to the tendons and peritendinous tissues to facilitate the next step of treatment. Debridement is performed to reduce post-traumatic inflammatory response and avoid the accumulation of large amounts of plasma exudate in the wound, which may cause severe tendon adhesion after surgery.

3. Tendon repair: The principle of repair is no tension, no torsion, and no damage. Postoperative tendon adhesion and re-rupture are the main complications, and tendon adhesion is a difficult problem that has not yet been completely solved.
