radial styloid fracture
Introduction
Introduction to sacral styloid fracture Most of the fractures of the sacral styloid process are on the palm of the hand when landing, and the violent impact on the lower end of the humerus along the scaphoid bone; or the hand-cranked car engine, the inverted rocking handle hits the fracture caused by the stem of the humerus, so there is also the name of the crank handle fracture. The fracture line is often transverse, affecting the ankle joint, and the fracture block is mostly displaced. basic knowledge The proportion of the disease: the incidence of this disease in trauma patients is about 0.8% -1% Susceptible people: no special people Mode of infection: non-infectious Complications: elbow valgus deformity
Cause
Causes of sacral styloid fracture
(1) Causes of the disease
Mostly caused by indirect violence and pulling violence.
(two) pathogenesis
Clinically, a simple fracture of the styloid process of the humerus can often be encountered. Most of the fractures are caused by the fall of the palm of the hand. The violence passes through the boat and the bone is transmitted. The fracture fragments are mostly horizontal or slightly oblique (Fig. 1), and are moved to the distal end and the lateral side. In addition, if the wrist is excessively ulnar, the sudden pulling of the radial collateral ligament may also cause a styloid fracture, and the appearance is avulsion.
Prevention
Prevention of sacral 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 sacral styloid fracture Complications elbow valgus deformity
The disease mainly causes elbow deformity and limited wrist joint activity, and dysfunction is the main complication.
Symptom
Symptoms of sacral styloid fractures Common symptoms Joint swelling and severe pain
1. The general fracture sign is that the distal part of the wrist of the injured wrist has swelling, pain and tenderness.
2. The ulnar deviation test is positive when the wrist joint is skewed to the ulnar side and there is severe pain on the temporal side.
Examine
Examination of the sacral styloid fracture
No relevant laboratory tests.
X-ray examination can confirm the diagnosis.
Diagnosis
Diagnosis and diagnosis of sacral styloid fracture
1. The history of trauma is clearer.
2. Clinical manifestations of pain in the styloid process of the humerus, increased pain during tenderness and ulnar deviation.
3. X-ray examination of the conventional X-ray film can confirm the diagnosis.
