ulnar shaft fracture
Introduction
Introduction to ulnar shaft fracture It is relatively rare, and there are generally no problems in diagnosis and treatment. After timely and appropriate treatment, most patients can restore their original functions, and a small number of patients may have different degrees of sequelae. . basic knowledge Sickness ratio: 0.05% Susceptible people: no specific people Mode of infection: non-infectious Complications: upper 1/3 of the ulnar fracture combined with dislocation of the humeral head
Cause
Causes of ulnar shaft fracture
Causes:
More caused by direct violence.
Pathogenesis:
It is more common when a sudden attack by an external force is caused by a direct impact of a stick when the patient raises his hand to cover the head and face. Because it occurs in the case of a strong person in the road, it is also known as a night stick fracture. This fracture line is mostly horizontal. Or with a triangular bone block (Figure 1), due to the support of the humerus, combined with less adhesion muscles, the degree of displacement is also slightly.
Prevention
Ulnar fracture prevention
Patients who have been injured for 2 to 4 weeks, their bodies are no longer so weak, their appetite and gastrointestinal functions are restored. At that time, nutrition can be properly supplemented. Foods such as bone soup, fish, eggs and animal liver are better. At the same time, you should also eat more radishes, tomatoes, green peppers, etc. These foods can meet the needs of bone growth and promote wound healing.
Complication
Ulnar fracture of ulnar shaft Complications : 1/3 of the ulnar fracture combined with dislocation of the humeral head
It should be noted that sometimes the humeral head dislocation.
Symptom
Ulnar fracture symptoms common symptoms long bone swelling pain simple fracture subcutaneous hematoma residual strain fracture
The full length of the ulna is subcutaneous and shallow, so the subcutaneous hematoma at the fracture is easy to be found after the injury. There is obvious tenderness at this place, and the bone friction sound between the ends can be touched. In the clinical examination, the position of the humeral head and the elbow should be noted. Swelling, tenderness, so as not to miss the dislocation of the humeral head, often missed diagnosis of crack fractures, so the type of fracture is not deformed, no bone friction, only local swelling and tenderness, be vigilant at work.
Examine
Ulnar fracture examination
No relevant laboratory tests.
The shot included the elbow joint and the X-slice of the forearm of the wrist joint.
Diagnosis
Diagnosis and diagnosis of ulnar shaft fracture
History of trauma, local hematoma, tenderness, bone rubbing and abnormal activity, X-ray examination can clearly show fractures.
