Ischemic contracture of forearm and hand muscle groups
Introduction
Introduction The lower part of the radial artery is the most common clinical manifestation, which occurs in children, especially in the supracondylar fracture of the humerus. It mainly causes ischemic contracture of the forearm and hand muscles, which is called Volkmann ischemic contracture.
Cause
Cause
(1) Causes of the disease
In addition to guns and bullets can cause injuries, local fractures are also more common.
(two) pathogenesis
The radial artery was connected to the radial artery (lower edge of the great round muscle), and the lower end was 2.5 cm below the elbow fossa; then it was divided into two ulnar arteries and the radial artery. The incidence of injury is high. In addition to gunshot wounds and shrapnel injuries, the humeral shaft and supracondylar fractures of the humerus are common causes of damage. In the middle of the humerus, it is easy to be accompanied by sacral nerve and median nerve injury. In the upper part of the iliac crest, the median nerve involvement is more common, and the total companion rate can reach 60% to 70%.

Diagnosis
Differential diagnosis
Middle iliac artery injury: In addition to more common humeral shaft fractures, transcatheter arterial catheterization and percutaneous puncture can also cause secondary thrombosis, resulting in the same consequences for the forearm and hand; in this case, the median nerve is also easy Dysfunction.
Upper radial artery injury: less common than the former two, because the lateral branch of the vascular network of the shoulder joint is rich, so once blocked, its impact on limb blood supply is lighter than the former two.
X-ray examination can exclude bone damage.
