Aetiology
Crushing injury of the thumb is caused by a direct impact to the thumb. This can be caused by a sports injury, a fall, or an accident, such as a car crash.
Diagnosis
Diagnosis of a crushing injury of the thumb is made through a physical examination, which will reveal swelling, tenderness and bruising. X-rays may be taken to look for fractures or other damage.
Differential diagnosis
Other conditions that can cause similar symptoms include sprains, strains, tendinitis and fractures.
Treatment
Treatment for a crushing injury of the thumb may include rest, ice, compression and elevation. Non-steroidal anti-inflammatory drugs (NSAIDs) can help reduce pain and swelling. If the injury is severe, surgery may be needed to repair the damaged tissues.
Prognosis
The prognosis for a crushing injury of the thumb depends on the severity of the injury. Minor injuries may heal on their own with rest and proper care. More severe injuries may require surgery and may take longer to heal.
