A nondisplaced fracture of the proximal third of the navicular bone, also known as the scaphoid bone, is a common injury that occurs in the wrist. This type of fracture is often caused by a fall onto an outstretched hand or a direct blow to the wrist. The proximal third of the navicular bone is the area closest to the wrist joint, and fractures in this area can be particularly problematic due to its limited blood supply.
The most common cause of a nondisplaced fracture of the proximal third of the navicular bone is a fall onto an outstretched hand. This type of injury is often seen in athletes who participate in sports that involve contact or high impact, such as football, basketball, and skateboarding. Direct blows to the wrist can also cause this type of fracture, as can repetitive stress injuries that occur over time.
The symptoms of a nondisplaced fracture of the proximal third of the navicular bone can vary depending on the severity of the injury. Common symptoms include pain and swelling in the wrist, difficulty moving the wrist, and tenderness when pressure is applied to the affected area. In some cases, a small bump or deformity may be visible on the wrist.
Treatment for a nondisplaced fracture of the proximal third of the navicular bone typically involves immobilization of the wrist with a cast or brace. In some cases, surgery may be necessary to align and stabilize the bone. It is important to seek medical attention as soon as possible after the injury occurs to prevent further damage and promote proper healing.
