A finger dislocation is an injury to the joint of the the finger bones where the joint separates and bones moved apart, causing malalignments of bones of a normal joint. Usually, dislocations in finger joints happen when the finger is bent backwards or side wards beyond its normal range of motion.
The medical terms of the bones of the finger is known as phalanges. The bones in the hand before the finger is termed as metacarpal bones. Every knuckle of the hands and fingers are connected by a joint between each of these two bones, and worse - every joint can be dislocated in an injury:
Symptoms of Finger Dislocation
A dislocated finger is crooked, painful and swollen, and its surface skin may be cut, scraped or bruised. If a dislocated finger has been straightened on the playing field, it may feel abnormally loose, weak or unstable afterward.Usually pain will set in after the adrenaline wear off, following which stiffness and tightness sets in, resulting in a stiff finger.
Your doctor will suspect that your finger is dislocated if it appears deformed. In some cases, your doctor may order an X-ray of the finger to rule out the presence of fractures. When a finger bone is pulled away from connected tendons, it is common for a fragment of bone to separate from the main bone and stay with the tendon, a condition known as an avulsion fracture.
Usually, you can return to your sport once your dislocated finger has been realigned, following a confirmation from your doctor that the injured joint is stable with no presence of bone fracture, and your finger tenderness and swelling have improved. For a few weeks, you will need to wear a customized finger splint or buddy tape, which is used to strap the injured finger to an uninjured finger nearby for support.
If you need surgery to repair your dislocated finger, it usually takes at least six to ten weeks for soft tissue to heal before you can return to your sport.Soft tissues will require four to six weeks to heal and stabilize, and from week two to three onwards, you need to start hand therapy to manage and prevent stiffness.
After your dislocated finger has been treated, you often can prevent it from being injured again by using a protective splint, taping it to another finger or, in some cases, using a cast. I often encourage customized splinting instead of casting, as casts are heavy, itchy, permanent and can be ill-fitting when the swelling has subsided.
A dislocated finger can be corrected with or without injecting local anesthesia (sometimes adrenaline is enough to block off pain). To correct the dislocation, the doctor will press against the displaced bone to dislodge the bone if it is caught against the side of the joint. As the end of the bone is freed, the doctor can pull outward to restore the bone to its correct position (termed as closed reduction). Once your finger joint is back in its normal position, you will wear a splint or tape the finger to another finger for three to six weeks, depending on the specific type of your dislocation.
If the doctor cannot straighten your finger using closed reduction or if your injured joint is not stable after closed reduction, your dislocated finger may need to be repaired surgically. Surgery is also used to treat finger dislocations that are complicated by large fractures or fractures that involves the joint.
When Should You Call a Professional?
You should call your doctor immediately if you injure your finger and your finger is crooked, deformed, painful or swollen. If you are an athlete and someone straightens your injured finger on the playing field, check with your doctor or your on-site physiotherapist to make sure that the injured joint is stable and not fractured. A dislocated joint that has an open wound should not be moved. It should be carefully splinted and evaluated immediately by a physician.
Usually, recovery and rehabilitation for following finger dislocation is usually good, though it will likely take about six months for your finger pain to resolve. Often, there will be permanent swelling around the injured joint, and especially in an injured proximal interphalangeal finger joint.
Hand Therapy for Finger Dislocation
The biggest challenge following a finger dislocation is decreased range of motion and stiffness. Regular and early hand therapy, which will include heat therapy to soften stiff structures, exercise therapy to strengthen weakened muscles, scar management to decrease scarring, customized splinting to keep the injured joint aligned, and ultimately restore your joint to full movement and function.
