ganglion cyst
Introduction
Introduction Tendon cyst: It is a cystic benign mass that grows in the tendon and its content is liquid. Cysts generally develop slowly. Except for local lumps, there are few symptoms and occasional local soreness. It can be caused by injuries, excessive strain (especially in the hands and fingers), osteoarthritis, some immune diseases, and even infections. When the local labor is excessive, the labor is injured, or the cold is cold, the blood and blood are stagnation, and the blood can not support the gluten. A cystic mass with a hemispherical shape, a smooth surface and a large tension appears on the dorsal, volar or instep of the wrist.
Cause
Cause
1. Tenosynovitis, tendon cysts, and ganglion cysts are common and frequently seen in the clinical motor system, and these diseases are associated with certain occupational and operational techniques.
2, when the local labor is excessive, the accumulation of fatigue, or cold, blood stasis, blood can not support the disease and disease.
3, can be injured, excessive strain (especially in the hands and fingers), osteoarthritis, some immune diseases, and even infection may also cause.

1, in addition to local lumps, there are few symptoms, occasionally local soreness.
2. A cystic mass with a hemispherical shape, a smooth surface and a large tension appears on the dorsal, volar or instep of the wrist.
3, the tumor grows slowly, the pressure has a soreness or pain, and the base is fixed.

5, pathological examination: can determine the nature of the lesion, is the gold standard for the diagnosis of this disease.
Diagnosis
Differential diagnosis
Ganglion cyst
The ganglion cyst is more common in the clinic and occurs in the foot. It is more common in young adults. Individual cysts occur in the carpal tunnel or fistula, which can compress the nerve to cause the corresponding symptoms. A small number of cysts can disappear on their own and no longer relapse. Most cysts continue to increase or exist and should be treated. Conservative therapy can be given in the early stage. Local squeezing rupture or sac fluid is taken out with a needle and injected with steroids. Patients with ineffective conservative treatment can be surgically removed.
2. Tendonitis
Tendinitis is a degenerative change in tendon tissue, and simple tendonitis is the main cause of spontaneous fractures such as Achilles tendon and biceps tendon. Typical pathological changes include a decrease in organelles in tendon cells, a decrease in mucopolysaccharide and water, an increase in collagen fiber diameter, and an increase in light and dark bands. It is generally believed that the above pathological changes are related to the reduction of blood supply in the tendon, and the above pathological changes result in a decrease in the mechanical properties of the collagen fibers, which ultimately leads to spontaneous rupture of the tendon. Clinically common Achilles tendon and biceps tendon ruptures occur mostly in athletes and middle-aged patients. For patients with acute complete tendon rupture, surgical repair should be performed. For patients with chronic partial injury, conservative treatment can be given.
