What Are the Signs of a Sprained Forearm?
Forearm artery injuries are mostly caused by sharp weapon injuries, and car crash injuries are also a common cause. More common in young adults aged 20 to 40. The forearm arteries are mainly the radial, ulnar, and common interosseous arteries, and the superficial palm and deep palm arches formed to the hand. The hand arterial network formed by the superficial palm arch and deep palm arch has a good compensatory effect, and its collateral circulation is conducive to the compensatory effect of an arterial trunk injury of the forearm.
Basic Information
- English name
- forearm arterial injury
- Visiting department
- surgical
- Multiple groups
- 20 to 40 years old
- Common causes
- Sharp object stab wounds, sharp weapon injuries, car accident impact injuries, etc.
- Common symptoms
- Ulcer or radial artery pulsation weakened or disappeared, cold fingers, skin irritation, numbness, Raynaud's syndrome of fingers, atrophy of small fish, etc.
Causes of forearm artery injury
- Most of the injuries are caused by sharp object punctures. Except for the injured objects, the sharp thorns (margins) of fractures can easily cause damage to adjacent vascular stems. Arteriovenous veins may also cause arteriovenous fistulas at the same time, and it is also easy to cause accompanying neural stem damage. In the forearm arterial trunk injuries, the incidence of radial arteries is high and iatrogenicity accounts for a considerable proportion. Blunt impact injuries such as car accidents can also lead to arterial stray injuries.
Clinical manifestations of forearm artery injury
- Mainly manifested as symptoms of partial obstruction of blood supply to the hand, pulsation of the ulnar or radial artery weakened and disappeared, cold fingers, skin allergies and numbness. If the injury spreads to the superficial palmar arch, Raynaud's syndrome may occur on the fingers, and atrophy of the small fish may also occur. Open upper extremity arterial trauma can lead to major bleeding, which can lead to ischemic shock.
Forearm artery injury check
- Arterial angiography
- Can clearly diagnose vascular injury and the location and extent of injury.
- 2. Color Doppler ultrasound
- Can be used as an alternative to angiography, convenient, sensitive and high specificity. Can be used as a preferred check.
Forearm artery injury diagnosis
- It is not difficult to make a diagnosis based on trauma and clinical manifestations. Combined with color Doppler ultrasound, the diagnosis can be clearly defined.
Forearm artery injury treatment
- Forearm vascular injury is mainly based on surgical repair based on thorough debridement.
- 1. Mainly repair, repair of the forearm arterial trunk fracture and functional reconstruction are required in principle.
- 2. The ulnar artery and radial artery rupture must be repaired at the same time, otherwise the hand function will be seriously affected.
- 3. Fractures and vascular injuries should be treated simultaneously.
- 4. Pay attention to the muscular interval syndrome. Injury caused by squeezing, the forearm soft tissues are often affected at the same time, which makes muscle interval syndrome prone, which will aggravate the injury. In this case, the muscle interval should be fully cut and decompressed as soon as possible, otherwise the hand function will be lost.
