A nondisplaced fracture of the middle third of the navicular bone, also known as the scaphoid bone, is a common injury of the wrist. The navicular bone is a small, boat-shaped bone located on the thumb side of the wrist. A nondisplaced fracture means that the bone is broken, but the pieces remain in their normal position.
Causes
The most common cause of a nondisplaced fracture of the middle third of the navicular bone is a fall onto an outstretched hand. This type of injury is common in athletes who participate in sports that involve contact, such as football or basketball. It can also occur in non-athletes who fall on an outstretched hand.
Symptoms
The symptoms of a nondisplaced fracture of the middle third of the navicular bone include:
If you experience these symptoms after a fall or injury to the wrist, you should seek medical attention immediately.
Treatment
The treatment for a nondisplaced fracture of the middle third of the navicular bone depends on the severity of the injury. In most cases, a cast or splint will be applied to the wrist to immobilize the bone and allow it to heal. You may need to wear the cast or splint for several weeks.
In some cases, surgery may be necessary to repair the fracture. This is more likely if the fracture is displaced (the bone pieces are not in their normal position) or if there is damage to the blood supply to the bone.
Conclusion
A nondisplaced fracture of the middle third of the navicular bone is a common injury of the wrist, often caused by a fall onto an outstretched hand. If you experience symptoms such as pain, swelling, and difficulty moving your wrist and thumb after an injury, seek medical attention immediately. Treatment may involve a cast or splint, or in more severe cases, surgery.
