Introduction

Introduction In patients with distal radius fractures, wrist pain is swollen, especially for palmar flexion. The disease is caused by indirect external force. When falling, the elbows are straight, the forearms are in front of the fore, the wrists are stretched back, and the palms are on the ground. Stress occurs at the distal end of the humerus and fractures occur. That is, the dorsal side of the wrist is raised and the palm side is protruding. The outline of the ulnar styloid disappeared. The wrist is widened and the hand is displaced to the temporal side. The lower end of the ulna protrudes, and the styloid process of the humerus moves up to or beyond the level of the ulnar styloid process. There is tenderness at the distal end of the humerus, which can reach the fracture end that is displaced to the back of the jaw. The comminuted fracture can touch the bones.

Cause

Cause

The disease is caused by indirect external force. When falling, the elbows are straight, the forearms are in front of the fore, the wrists are stretched back, and the palms are on the ground. Stress occurs at the distal end of the humerus and fractures occur.

The majority of patients with distal radius fractures are injured in the wrist. The axial force is mostly transmitted through the central column and the lateral column through the scaphoid and lunate bone to the distal end of the humerus. Between the lunate bones, the force is mainly concentrated on the scaphoid ligament, which is easy to cause the scaphoid ligament injury and the separation of the boat and the moon. The distal joint surface of the humerus tends to be shattered. Because the palmar flexion is not conducive to the repair of the dorsal structure, the ulnar deviation increases the separation of the scaphoid and makes the diaphragmatic muscle tense, which is easy to cause the temporal displacement, which is not conducive to improving the instability of the wrist joint.

Patients with distal radius fractures have the following clinical manifestations:

Wrist pain swelling, especially with limited palmar flexion. In severe cases of fracture displacement, there may be a fork-shaped deformity, that is, the dorsal bulge of the wrist and the volar protrusion. The outline of the ulnar styloid disappeared. The wrist is widened and the hand is displaced to the temporal side. The lower end of the ulna protrudes, and the styloid process of the humerus moves up to or beyond the level of the ulnar styloid process. There is tenderness at the distal end of the humerus, which can reach the fracture end displaced to the back of the jaw. The crushed fracture can touch the bones.

Diagnosis

Differential diagnosis

"Wrist stenosis tendon bursitis" is a clinically common pain on the thumb side of the wrist. Ten times as many as men are in women. The mass of the wrist that is as hard as the cartilage is one of the symptoms of the ganglion cyst. The sacral cyst (thecal cyst) is the most common type of mass on the dorsal aspect of the wrist. It can also occur on the joint capsule and tendon sheath in other parts of the body. The long bone spur of the wrist is a phenomenon in which the wrist joint reinforces itself in response to degeneration. Generally speaking, if there is no compression to the nerve, there is no need to worry too much. As the age increases, each person will have a long bone spur more or less. situation.
