A jammed finger may require medical attention even if the joint moves normally and looks normal, according to the American Society for Surgery of the Hand, or ASSH. Permanent issues can result without proper treatment of many types of injuries that cause jammed fingers.
A jammed finger may require nonsurgical or surgical intervention, depending on the severity of injury, notes the ASSH. Nonsurgical treatment methods include splinting and buddy strapping the injured joint to the neighboring finger.
Jammed fingers result from compression of the fingertip toward the hand, causing the ligaments to stretch, states the ASSH. Depending on the strength of the force that causes the compression, the joint may sprain, or the ligaments may tear completely.
