Rectal cyst

Radius, the radius is a pair of bone structure that is part of the forearm and is located in the anterior external part of the ulna.

To understand how and why a ray cyst is formed on this site, you need to remember the radius device: 

• The body of the bone is triangular in shape and has three surface zones - posterior, anterior, lateral.
• Upper epiphysis.
• Lower epiphysis.

Symptoms of a cyst of a radial bone

In the radius, solitary cysts are formed most often, which are easier to treat and decrease more rapidly in case of a pathological fracture. Aneurysmal tumors in this bone are extremely rare, they develop more active than solitary ones, are more evident in the sense of clinical signs and most often recur. In general, in the radius of the bone, any cystic formation is more fibrous in nature, and often in fractures in the bone tissue hygromes and other synovial neoplasms are formed, which can be mistakenly defined as ACC. Anyway, a benign tumor in the bone tissue of the forearm, especially in the radius, develops for a long time without symptoms and its first sign is a pathological, spontaneous fracture.

Fracture can be formed by the transfer of gravity, bruise, fall, when a person instinctively leans on his outstretched arms. According to statistics, a pathological fracture is noted in 65-70% in the distal epimetaph of the radius - radius. If the fracture is caused not by osteoporosis and other pathologies of bone tissue, it is in this zone that the bone cyst should be identified. Trauma is often combined with such injuries: 

• Fracture or fracture of the processus styloideus - styloid elbow process.
• Dislocation of os lunatum - semilunar bone.
• Fracture of the tarsus (os scaphoideum) - scaphoid bone.
• Stretch or rupture of the wrist band.

In children, such fractures can occur against a background of metabolic disorders. In adults, especially in women, in addition to the fact that the intraosteal cyst destroys the structure of the tissue of the radius, trauma can provoke hormonal changes and osteoporosis.

Diagnosis of the cyst of the radius

The diagnosis of the fracture confirms the X-ray in two projections, if a CCM or ACC is suspected, a CT scan, scintigraphy, should be prescribed. The detected cyst must be punctured, the material is sent to the laboratory for histological examination. As a rule, the cyst of the radial bone is detected after the edema subsides, after 10-14 days, so during this period it is desirable to conduct a repeated X-ray examination to confirm or exclude the presence of a benign tumor in the bone tissue.

Treatment of a cyst of a radial bone

In general, a pathological fracture in children under the age of 15 years is considered a kind of "therapeutic" trauma, after which the cyst of the radial bone in most cases decreases and disappears. Adult patients with an identified cyst should be monitored for 2-3 months after the fracture, if the cyst does not subside, it is removed by surgery.

Both after fracture of the radial bone, and after resection of the cyst, complications are possible, especially they are noted in elderly patients older than 55-60 years: 

• Trophononeurosis, posttraumatic dystrophy of the tissues of the hand.
• Infringement of nerve endings, neuritis of the median nerve (Turner's disease).
• Bone deformity with incorrect bone consolidation after fracture.
• Post-traumatic spotted osteoporosis.

To ensure that the damaged bone does not move, to seal and close the bone defect during surgery to remove the radial cyst, osteotomy and substitution of the resection part with artificial or autologous material are carried out. To restore the function of the hand takes at least six months, adult patients recover longer - up to a year and a half.
