A dislocated finger occurs when the bones that form a joint are forced out of their normal alignment. This common injury can happen to any finger on the hand, although some joints are more frequently affected than others. A dislocation causes the finger to appear visibly out of place and can result from various types of trauma. Understanding what a dislocated finger is and how to respond can help manage the injury effectively.
Understanding Finger Dislocations
Fingers are composed of small bones called phalanges, which connect at joints. These joints are stabilized by strong fibrous tissues known as ligaments, along with a joint capsule that encloses the joint. A finger dislocation happens when an external force pushes the ends of these bones out of their proper contact within the joint, often stretching or tearing the supporting ligaments.
Dislocations commonly result from a “jamming” force or forceful hyperextension, where the finger is pushed beyond its normal range of motion. This can occur during sports activities, such as when a ball strikes an outstretched finger, or from a fall where the hand is used to break impact. While any finger joint can dislocate, the proximal interphalangeal (PIP) joint, the middle knuckle, is the most frequently dislocated.
Recognizing a Dislocated Finger
Severe pain at the injury site is typically the first and most prominent symptom. The affected finger will usually appear visibly deformed, looking crooked, bent at an odd angle, or otherwise out of its normal alignment. Swelling around the injured joint develops quickly, often accompanied by bruising due to damaged blood vessels. Movement of the affected finger will be difficult or even impossible, and attempting to move it will likely intensify the pain. In some cases, a dislocated finger might also present with numbness or tingling, which could indicate nerve compression.
Responding to a Dislocated Finger
It is important to avoid attempting to “pop” the finger back into place yourself. Self-reduction can cause additional damage to surrounding structures, potentially leading to permanent injury.
To manage the injury, immobilize the finger using a makeshift splint or by gently taping it to an adjacent, uninjured finger. Apply ice wrapped in a cloth to the injured area for 15 to 20 minutes at a time to help reduce swelling and pain. Elevating the hand above heart level can also help minimize swelling. Remove any rings or jewelry from the injured hand promptly, as swelling can make removal difficult later.
Seeking prompt medical attention is crucial for a dislocated finger, ideally within a day of the injury. A medical professional will typically perform an X-ray to confirm the dislocation and check for any associated fractures, which can sometimes occur with dislocations. The primary treatment involves reduction, a procedure where the healthcare provider carefully manipulates the bones back into their proper alignment, sometimes using a local anesthetic to minimize discomfort.
After reduction, the finger will be immobilized using a splint or by “buddy taping” it to an adjacent finger for support during the healing process. In more complex cases, such as those involving significant ligament tears or fractures, surgery may be necessary to realign the joint or repair damaged tissues.
Recovery time for a dislocated finger varies depending on the severity of the injury, with most individuals returning to normal activities within six to twelve weeks. However, it can take anywhere from three to six months for the finger to feel fully normal, and some mild discomfort or swelling might persist for up to 12 to 18 months. Pain management with over-the-counter or prescription medication may be recommended. Rehabilitation exercises are important to restore range of motion and strength to the finger. Some permanent stiffness or minor swelling in the affected joint can occur even after complete healing.
