See extensor tendon injury hang what division?

summary

Most of the hand tendon injuries are open, most of them are cutting injuries, often combined with neurovascular injury or bone and joint injury, and can also occur closed laceration. After tendon rupture, the corresponding joints lose their function. If the flexor digitorum superficialis tendon is broken, the proximal interphalangeal joint of the corresponding finger cannot be flexed; Rupture of flexor digitorum profundus tendon showed that distal interphalangeal joint could not bend; The distal and proximal interphalangeal joints could not be flexed if the flexor tendons were broken. As the internal hand muscle is still intact, the flexion of metacarpophalangeal joint is not affected. When the extensor tendon is broken in different parts, the corresponding joint can not be extended and deformity may occur. What department does that see extensor tendon injury hang?

Symptoms: the main clinical manifestation of this disease is that the corresponding joint loses its function after tendon rupture. 1. The proximal interphalangeal joint could not be flexed due to the rupture of superficial flexor tendon; 2. Rupture of flexor digitorum profundus tendon showed that distal interphalangeal joint could not bend; 3. The distal and proximal interphalangeal joints could not be flexed if the flexor tendons were broken. As the internal hand muscle is still intact, the flexion of metacarpophalangeal joint is not affected. 4. When the extensor tendon is broken in different parts, the corresponding joint can not be extended and deformity may occur.

Aloe Vera A, trauma hormone and glycopeptide mannan can promote wound healing and recovery. It has the functions of anti-inflammatory, bactericidal, heat absorption, swelling, softening skin and maintaining cell viability. Lemon rich contains a lot of vitamins, like antibiotics, with antibacterial and anti-inflammatory effect, as well as the role of clearing heat and detoxification, which is conducive to the recovery of patients.

This disease is mostly caused by sharp cutting injury, electric saw, etc., for traumatic factors caused by this disease, easy to diagnose, do not need other auxiliary examination, for closed injury caused by the situation, need to carry out physical examination, according to its characteristic clinical manifestations can be diagnosed, also do not need to do other examination. But we should pay special attention to the X-ray examination of the affected finger before treatment in patients with extensor tendon injury in zone I, whether it is fresh or old.

matters needing attention

The main injury factors of this disease are sharp cutting injury, electric saw injury, shock finger injury and crush injury caused by closed injury. It is often combined with neurovascular injury or bone and joint injury, and closed laceration may also occur. This disease is mainly caused by traumatic factors, so pay attention to production safety, do a good job in occupational protection, prevent wrist injury, is the key to the prevention and treatment of this disease.
