Elbow bone protrusion

The importance of the elbow joint is self-evident. It is a very important joint in the human body. Because it is used very frequently, the elbow joint is prone to problems. Bone protrusion at the elbow joint is a typical one. Bone protrusion in the elbow joint is most likely caused by a ganglion cyst. We can learn about this disease and make a judgment based on our own situation. If we are not sure, we should go to the hospital for diagnosis and treatment in time.

Clinical manifestations

1. General symptoms

Ganglion cysts can occur at any age, but are more common in young and middle-aged people, and more common in women than in men. The cysts are slow growing, round, and usually no larger than 2 cm in diameter. There are also sudden discoverers. A few may disappear on their own or grow again. In some cases, apart from local swelling, there is no conscious discomfort and sometimes mild tenderness. In most cases, there is local soreness or discomfort, which affects activities. The size of the cyst has no direct relationship with the severity of the symptoms, but is related to the tension of the cyst. The greater the tension, the harder the tumor and the more obvious the pain.

2. Local symptoms

During the examination, a round lump with a smooth appearance and clear boundaries can be felt. The surface skin can be pushed, there is no adhesion, and there is soreness or pain when pressed. Most cysts have high tension and are firm lumps, while a few are soft but all have a cystic feeling. The cyst has a fixed base and little movement.

(1) Ganglion cysts of the wrist mostly occur on the dorsal side of the wrist, with a few occurring on the palm side. The most common site is the dorsal joint capsule of the wrist joint on the radial side of the common extensor tendon, followed by the radial flexor carpi tendon and the abductor pollicis longus tendon. Cysts may also develop in the flexor tendon sheath within the carpal tunnel, compressing the median nerve and inducing carpal tunnel syndrome. A few ganglion cysts may occur on the flexor tendon sheath of the fingers beyond the metacarpophalangeal joint. They are the size of a grain of rice and as hard as cartilage.

(2) Dorsal pedis ganglion cysts are the most common type of ganglion cysts in the foot and ankle, and they usually originate from the tendon sheath of the extensor digitorum longus tendon on the lateral side of the dorsalis pedis artery. Ganglion cysts in the tarsal tunnel can compress the tibial nerve and are one of the causes of tarsal tunnel syndrome.

examine

Ultrasound examination can determine the nature of the mass. X-rays can determine whether there are changes in the surrounding bones and joints.

diagnosis

The diagnosis can usually be made based on clinical manifestations, physical examination and B-ultrasound examination.

treat

A small number of ganglion cysts may resolve on their own, but some patients still experience recurrent attacks after multiple treatments.

1. Non-surgical treatment

Although the recurrence rate of conservative treatment of ganglion cysts is high, this method is the least invasive and easily accepted by patients, and can be used as the preferred method clinically. Ganglion cysts can be ruptured by squeezing and gradually absorbed on their own, but they may recur after treatment. Those that are connected to the joint cavity are not easy to rupture. The cyst fluid can be extracted by puncture, and then pressure and massage can be applied, or adrenal cortical hormone or hyaluronidase can be injected after the cyst fluid is extracted, and local pressure bandage can be applied for 2 days, which has a certain therapeutic effect.

2. Surgery

When other treatment methods are ineffective, ganglion cysts can be surgically removed. After surgery, strenuous activity of the affected joint should be avoided to prevent recurrence.
