Radius and ulna styloid fractures
Introduction
Brief introduction of humerus and ulnar styloid fracture This disease is rare. When the child falls, the palm of the hand touches the ground. The impact force acts on the lower end of the humerus through the scaphoid bone to cause a transverse fracture of the sacral styloid process. There are also direct impacts, such as the car shaker counterattack and the injured. In addition, the wrist joint is strong and the collateral ligament is strongly pulled, causing the avulsion fracture of the sacral styloid process. The fracture block is small and displaced to the distal side. The ulnar styloid fracture is often associated with ligament traction, often accompanied by Colles fracture, and there is also a single fracture. basic knowledge The proportion of the disease: the probability of the population is 1.6% Susceptible people: no special people Mode of infection: non-infectious Complications: sacral styloid fracture
Cause
Causes of humerus and ulnar styloid fractures
Osteoporotic fractures (20%):
Osteoporotic fracture (brittle fracture) refers to a bone fracture caused by decreased bone mineral density and bone mass after osteoporosis, which is caused by mild violence or even daily activities. It is a pathological fracture and is a bone. The most serious consequences of quality loosening.
Direct violence (20%):
Fractures caused by firearm wounds, puncture wounds, crush injuries, machine rolling injuries, etc., such fracture types are mostly comminuted, transective and open fractures.
Indirect violence (20%):
Violence is fractured at the point of action by conduction, lever or rotation. If a fall occurs, a clavicle fracture can occur in the palm of the hand. What causes fractures?
Pulling violence (20%):
In the process of sudden tension contraction of the muscles, the antagonistic muscles fail to coordinate and suddenly suffer resistance, but the muscles still involuntarily contract and pull, which can cause avulsion fractures such as the humerus and olecranon.
The disease is mainly caused by traumatic factors. When the fall, the palm of the hand touches the ground, and the impact force acts on the lower end of the humerus through the scaphoid bone to cause a transverse fracture of the styloid process of the humerus. It is also directly impacted, such as a car shake to counterattack and cause injury. In addition, the wrist joint is strong and the collateral ligament is pulled strongly, causing the avulsion fracture of the sacral styloid process.
Prevention
Prevention of humerus and ulnar styloid fracture
The disease is mainly caused by traumatic factors, so pay attention to production and life safety, avoid trauma, and ensure personal safety is the key to prevent this disease. In addition, it is necessary to pay attention to the treatment should proceed from the whole, try to restore the function of the patient's affected limb.
Complication
Complications of humerus and ulnar styloid fractures Complications of the styloid process
The disease mainly causes elbow deformity and wrist joint activity limitation. Dysfunction is the main complication. At the same time, attention should be paid to the overall treatment of the wrist joint. It is reported that the triangular fibrocartilage rupture of the lateral column of the wrist joint is caused by the injury of the wrist joint. Poor reduction due to fractures of the styloid process can lead to chronic wrist pain and limited wrist function.
Symptom
Symptoms of humerus and ulnar styloid fractures Common symptoms External forearm and fingers... Forearm traumatic pain Forearm rotation pain Forearm pronation deformity Forearm shortening
The disease mainly manifests as local swelling, pain, tenderness and bone rubbing, subcutaneous blood stasis, severe blood in the wrist joint, and limited wrist activity.
Examine
Examination of humerus and ulnar styloid fractures
The auxiliary examination method for this disease is mainly X-ray examination: when the styloid process of the humerus is fractured, the fracture line is not easy to be seen on the lateral X-ray photograph. On the X-ray film, a transverse fracture line is seen, starting from the wrist. The scaphoid, the intersection of the lunate articular surface, and the outward travel stop at about 1 cm from the tip of the sacral styloid process, and the ulnar styloid fracture, you can see a slight shift.
Diagnosis
Diagnosis and diagnosis of humerus and ulnar styloid fracture
The disease mainly manifests as local swelling, pain, tenderness and subcutaneous congestion. Many joint injuries can have similar symptoms. Therefore, these diseases need to be identified clinically. The X-ray examination method is mainly used for differential diagnosis. The main diseases to be identified are as follows:
1. The fracture of the humerus shaft.
2, humeral head fracture.
3, wrist dislocation and so on.
