What Is a Tendon Cell?

Tendon cells are the basic functional unit of tendons. They synthesize and secrete extracellular matrix such as collagen to maintain the metabolism of tendon tissue.

Tendon cells

Right!

Explanation: Cord-like or membranous dense at both ends of the muscular abdomen

When people stand on their toes with their heels off the ground, there is a very strong and tight tendon between the heel and calf. This is the Achilles tendon. It is a combination of the soleus muscle from the back of the tibia and the tendon of the two muscles from the gastrocnemius muscle inside and outside the femur. It is one of the most powerful tendons in the human body. People walk, run, and jump on this powerful tendon. If the Achilles tendon is completely broken, it will be very difficult.

The Achilles tendon is about 15cm long and is the thickest tendon in the human body. It is formed by the fusion of the calf triceps (soleus, gastrocnemius, and external head) tendons about 15cm above the heel. Obvious strip-shaped protrusions are formed on the body surface. The main function of the Achilles tendon is flexing the calf and plantar flexion. People can jump, run on the ground, and rely on it. In addition, the Achilles tendon also affects a person's uprightness.

Divided into two categories: one is spontaneous rupture, common in athletes and actors; the other is trauma, usually accompanied by skin damage or fractures

Gastrocnemius tendon

Cell in vitro culture technology (referred to as:

Raise the affected limb, promote blood circulation and reduce swelling.

Physical therapy

In the early stage after surgery, ultrashort wave, ultrasound and other treatments can be selected. In the middle and late stage (wound healing) after surgery, paraffin therapy, audio therapy, and hydrotherapy can be used.

Exercise therapy.

(1) Passive activity: On the third day after the operation, under the protection of plaster, passive activity was started. The flexor tendon was completely flexed after the injury was repaired, and the extensor tendon was completely stretched after the injury was repaired. Every minute in the first week 2 10 minutes in a row. 3 times a minute for 15 minutes for the second week after surgery. 4 times a minute for 20 minutes for the third week after surgery. 5 times per minute for the fourth week after surgery. 25 minutes in a row. After that, the number of activities is gradually increased. In the morning, afternoon and evening, one unit of passive activities is performed.

(2) Active activities: Different opinions, our opinion is to start a small amount of mild active activities on the 15th day after the operation, 2 times per minute, for 5 minutes in a row, with mild exertion. 22 days after the operation, 3 per minute Repeatedly, 10 minutes in a row, with moderate force. Remove the external fixation 29 days after the operation, 4 times per minute, 20 minutes in a row, increase the force and gradually increase the number of activities. In the morning, afternoon, and evening, perform one unit of active activities. Passive activities are followed by active activities.

Occupational therapy

(1) Training in daily activities: such as wearing clothes, using tableware and personal daily life. Training can be started after removing the external fixation 4 weeks after the operation.

(2) Housework training: such as cooking, laundry, etc., training will begin in February after surgery.

(3) Craft therapy: such as weaving, clay sculpture, etc., training starts 2.5 to 3 months after the operation.

Brace therapy

According to the injury, go to a prosthetic plant to make a wrist and finger joint elastic movable bracket. After removing the external fixation one month after the operation, start to wear the bracket for activity training.

Rehabilitation

Some scholars think that the rehabilitation training time is within 10 days after surgery, and some scholars think that within 3 to 7 days after surgery. Some experience starts from 0 days, and the analysis report is as follows. 1: 0-7 days after flexor tendon repair After the operation, the wound was bandaged, the injured limb was fixed at the wrist flexion 30 ° 50 °, and the metacarpophalangeal joint flexed at 70 °. The interphalangeal joint was extended and straightened. From the upper middle 1/3 of the forearm to the mid-finger level of the finger, the nail of the affected finger is nailed with a strong glue, and a rubber band is attached to the palm of the forearm with a pin. The anesthesia has not disappeared, and active straightening and passive flexion exercises have begun 3 to 5 times each time, 10-20 times a day, and instruct patients to adhere to voluntary activities, the purpose of which is to allow the flexor tendon to have a sliding range of 0.5 to 1.0 under the injured surface to avoid tendon adhesions. This active straightening, Passive flexion includes a small range of motion, light pain, and the patient is easy to accept. The movement should be gentle during training, and the patient's pain should not be rough, or the patient will not be willing to cooperate with rehabilitation training next time. 2: After flexor tendon repair 8 Change the plaster support 14 days, the wrist joint does not change, the distal end of the plaster support reaches the metacarpophalangeal joint. The method is the same as before. Passive flexion, active extension Interphalangeal joints and metacarpophalangeal joints. 20 to 30 times a day, more than 10 times each time. If one or two fingers are damaged, the adjacent fingers can accompany the movement. The pain is reduced during this period, but it must not let the patient Active flexion of the fingers, the most likely cause the anastomotic tendon to break again. 3: 15-21 days after the flexor tendon repair, this period has been broken, the wound does not feel pain, swelling is reduced, and the plaster can be lined with human gauze near the wrist. The wrist has a range of 1 ° to 15 °. Active straightening, passive flexion of the wrist, metacarpophalangeal, and knuckle joints are often performed at the same time as active physical therapy. At this stage, patients must be warned not to remove the plaster by themselves. Large wrist flexion, flexion of the metacarpophalangeal joints. 4: 22-42 days after flexor tendon repair, the cast can be removed during this period, the wrist joint gradually straightens, and the interphalangeal and metacarpophalangeal joints can be fully flexed, and Do slight active flexion training, such as finger-stretching, cup extension, and finger spreading and clamping training, but do not hold strong grips and lift heavy objects, because tendon rupture may still occur. 5: Flexor tendon repair This period after 42 days after surgery is mainly to train patients to recover muscle strength and complete fine movements.
