Contusion of finger or thumb is caused by blunt trauma to the affected area. It can be caused by a direct impact such as a punch or a fall onto an outstretched hand. It can also be caused by repetitive activities such as typing or gripping objects.
Contusion of finger or thumb is diagnosed by physical examination of the affected area. The area may be swollen, discolored, and tender, and the range of motion may be limited. X-rays may be ordered to rule out other injuries such as fractures.
Other conditions that may have similar signs and symptoms as contusion of finger or thumb include fractures, sprains, and tendinitis.
Treatment for contusion of finger or thumb includes rest, ice, and elevation to reduce swelling and pain. Non-steroidal anti-inflammatory drugs (NSAIDs) may be prescribed to reduce inflammation and pain. Splints may be used to immobilize the affected area and allow for healing.
The prognosis for contusion of finger or thumb is generally good. Most patients recover without any long-term problems. However, if there is any muscle, nerve, or tendon damage, recovery may take longer.
