Hand tendon injury

Introduction to hand tendon injury The tendon injury of the hand is mostly open, with more cuts, often involving nerve injury or fracture, or a closed tear. Because the internal muscles are still intact, the flexion of the metacarpophalangeal joint is not affected. After the tendon breaks, the corresponding joint loses its function. The disease is mainly caused by traumatic factors, in which more cuts, often combined with nerve injury or fracture. For example, if the deep flexor tendon ruptures, the distal interphalangeal joints cannot be flexed; if the deep and shallow flexor tendons are broken, the distal and proximal interphalangeal joints cannot be flexed. The different parts of the extensor tendon are broken, and the corresponding joints cannot be stretched and deformed. Sometimes the tendon is not completely broken, although the joint can still move, but it is weak and painful when tested for resistance. basic knowledge The proportion of illness: 0.5% (the incidence rate is about 10% in patients with hand trauma, and the incidence rate is about 0.5% in labor injury) Susceptible people: no special people Mode of infection: non-infectious Complications: edema

Causes of hand tendon injury

The disease is mainly caused by traumatic factors, in which more cuts, often combined with nerve injury or fracture.

Hand tendon injury prevention

The main prevention of this disease is to correctly guide postoperative functional exercise:

(1) Early non-impedance functional exercise, restrictive passive activities 1 to 3 weeks after surgery, to promote the vertical alignment of new collagen fibers, reduce adhesions, and promote healing. In this period, under the strict guidance of medical staff, the affected limbs (referred to) passive flexion, Straighten the activity, the method is the same as above.

(2) Mid-term non-impedance functional exercise, 4 to 5 weeks after surgery, guide patients to mildly active limbs (finger), moderate movement during exercise, appropriate force, 10 times a day, 5 minutes each time to cause mild soreness It is advisable to avoid violent movements, massage the muscles and joints, and use local physiotherapy such as ultrashort wave, spectrum and other therapies.

(3) Functional exercise that gradually increases the impedance in the later stage. After 6 to 10 weeks, the passive activity is active. The affected limb (referring to) is 20 times, repeating once every 1 to 2 hours, and mastering the action essentials during practice. The functional activities are from simple to complex. Step by step, encourage patients to do daily life movements, completely remove the gypsum protection weight-bearing exercise after 4-8 weeks, gradually increase the impedance activity; 10 weeks later, according to the nature or willingness of the patient's work, carry out various kinds of homework training, in order to return to society, Get ready to resume work.

Hand tendon injury complications Complications edema

Hand tendon injury is a common injury in the hand. Improper handling often causes edema, tendon adhesion, tendon rupture and other complications, leading to severe finger function.

Symptoms of hand tendon injury Common symptoms Arm muscle strain, thumb, forefinger, dysfunction, tendon rupture, wrist, long bone spur, muscle strain, muscle, complete fracture, tension, fatigue, hand muscle atrophy, weakness, finger joint pain

After the tendon rupture, the corresponding joint loses its active function, such as the deep flexor tendon rupture, which means that the distal interphalangeal joint can not be flexed; if the deep and shallow flexor tendon is broken, the distal and proximal interphalangeal joints cannot be flexed.

The different parts of the extensor tendon are broken, the corresponding joints can not be stretched, and the deformity can occur. Sometimes the tendon is not completely broken, although the joint can still move, but the resistance test is weak and painful.

Examination of hand tendon injury

Physical examination of the patient can be found that the different parts of the extensor tendon are broken, the corresponding joints can not be stretched, and the deformity can occur, sometimes the tendon is not completely broken, although the joint can still move, but the resistance test is weak and painful.

Diagnosis and diagnosis of hand tendon injury

The disease mainly manifests as pain and dysfunction in the hand, so it is necessary to distinguish it from other injuries with the same symptoms in the hand.
