Other Mechanical Complications of Internal Fixation Device of Bones of Hand and Fingers

Internal fixation devices are commonly used to treat fractures of the bones in the hand and fingers. These devices can include metal plates, screws, pins, and wires that are used to hold the bones in place while they heal. While these devices are generally effective, they can also cause mechanical complications that can be painful and limit the function of the hand and fingers. Here are some of the other mechanical complications that can occur:

1. Malunion: When the bones do not heal in the correct position, it can cause a deformity of the hand or fingers. This can occur when the internal fixation device is not holding the bones in the correct position, or if the device fails before the bones have fully healed.
2. Nonunion: If the bones do not heal together at all, it is known as a nonunion. This can occur if the internal fixation device fails, or if there is not enough blood supply to the bones to promote healing.
3. Hardware failure: The internal fixation device can break or loosen over time. This can be due to stress on the device from normal hand and finger movements, or from trauma to the hand or fingers.
4. Hardware irritation: The metal hardware can irritate the surrounding soft tissue and cause pain, swelling, and redness. This can occur if the hardware is too large, too long, or if it is rubbing against the skin or other tissues.
5. Joint stiffness: If the hand or finger is immobilized for too long, it can cause a stiffness in the joint. This can be due to the internal fixation device limiting the movement of the bones and joint, or from scar tissue forming around the joint.

If you are experiencing any of these complications, it is important to seek medical attention from a qualified hand and wrist specialist. Treatment may include removing the internal fixation device, performing a corrective surgery, or providing physical therapy to improve range of motion and function of the hand and fingers.

In conclusion, while internal fixation devices can be effective in treating fractures of the hand and fingers, they can also cause mechanical complications. It is important to be aware of these potential complications and to seek medical attention if you are experiencing any pain or limitations in the function of your hand and fingers.
