Complications of Scaphoid Fractures: Nonunion and Avascular Necrosis
Scaphoid fractures can lead to two major complications: nonunion and avascular necrosis. Nonunion occurs when the fractured pieces fail to come together and heal properly. This is often the result of poor blood supply to the affected area. Conservative treatment may not be sufficient to promote healing, in which case surgery may be necessary to align the fractured pieces and facilitate the healing process.
Avascular necrosis, on the other hand, occurs when the blood supply to the bones is disrupted or completely cut off. This complication is more commonly observed in cases of displaced fractures. When the bone fragment loses its blood supply, the cells within it die, preventing proper healing. In such instances, bone grafts may be required to promote the regeneration and healing of the affected area.
Arthritis and Fractures: A Connection Worth Knowing
Fractures, regardless of their location, can potentially lead to the development of arthritis. When it comes to the scaphoid bone, however, arthritis is more likely to occur in cases of displaced fractures and subsequent complications. If you’re experiencing stiffness, pain, and a decrease in wrist mobility and function, these could be signs of arthritis.
