How is double fracture of radius and ulna formed?

summary

Ulnar and radial fractures refer to fractures of both ulnar shaft and radial shaft. Because of the local special anatomical structure, fracture dislocation is easy to occur after fracture, and it is difficult to maintain fixation, which is more common in adolescents. Direct and indirect (conduction or torsion) violence can cause ulnar and radial shaft fractures. After fracture, local swelling, pain, limb deformity, forearm rotation dysfunction, complete fracture can touch the fricative sound and bone fricative sound. How is double fracture of radius and ulna formed? Next, I'd like to share my views with you.

How is double fracture of radius and ulna formed?

Most of them are hit or machine injury. The fracture was transverse or comminuted, and the fracture line was in the same plane. The fall of the palm to the ground transmitted the middle or upper 1 / 3 fracture of the radius upward. The residual violence was transferred to the ulna through the interosseous membrane, resulting in ulnar fracture. Therefore, the fracture line was lower than the radius, which was transverse or serrated, and the ulna was short oblique fracture displacement.

At the same time, the forearm suffered external torsion force, resulting in fracture. When falling, the same side of the body inclines, and the forearm is excessively pronated or supinated, resulting in double bone spiral fractures. Most of them incline from the ulna to the radius, and the fracture line is in the same direction. The ulna fracture line is up and the radius fracture line is down.

Local swelling deformity and tenderness, bone frications and abnormal activities, forearm movement is limited. In children, there is often branchial fracture with angular deformity and no displacement of the bony end. Sometimes combined with median nerve or ulnar nerve radial nerve injury, should pay attention to check.

matters needing attention

Avoid eating more meat and bones. Some people think that eating more meat and bone after fracture can make the fracture heal early. In fact, modern medicine has proved that if fracture patients eat more meat and bone, it will not heal early, but will delay the healing time.
