Scaphoid Fractures Treatment & Surgery

What is a Scaphoid Fracture?

A scaphoid fracture is a break in the scaphoid bone, one of the small bones in the wrist located on the thumb side. The scaphoid plays a crucial role in wrist movement and stability. This type of fracture is common and usually results from a fall onto an outstretched hand, causing the scaphoid bone to break. Due to its location and limited blood supply, scaphoid fractures can be challenging to heal and may lead to complications if not treated promptly.

What Causes Scaphoid Fractures?

Scaphoid fractures are typically caused by:

• Falls: Falling onto an outstretched hand is the most common cause of a scaphoid fracture. The impact forces the wrist into an extended position, placing excessive stress on the scaphoid bone.
• Sports Injuries: Activities that involve a high risk of falling or direct impact to the hand, such as skateboarding, snowboarding, and contact sports, can lead to scaphoid fractures.
• Motor Vehicle Accidents: The force of a collision can cause significant trauma to the wrist, resulting in a scaphoid fracture.

Signs and Symptoms of Scaphoid Fractures

The symptoms of a scaphoid fracture can vary depending on the severity of the break but typically include:

• Wrist Pain: Persistent pain on the thumb side of the wrist, especially when trying to grip or squeeze an object or when moving the wrist.
• Swelling: Swelling around the wrist, particularly on the thumb side.
• Tenderness: Tenderness to touch in the anatomical snuffbox, a small depression on the back of the hand near the base of the thumb.
• Limited Range of Motion: Reduced ability to move the wrist, particularly when bending or extending the wrist.

Diagnosis of Scaphoid Fractures

To diagnose a scaphoid fracture, a healthcare provider will perform a thorough physical examination, assessing the wrist for pain, swelling, and range of motion. They may ask about your medical history and how the injury occurred to understand the condition better. Imaging tests, such as X-rays, are typically used to confirm the diagnosis and evaluate the extent of the fracture. In some cases, MRI or CT scans may be necessary to provide a more detailed view of the bone and detect fractures that are not visible on X-rays.

Treatment for Scaphoid Fractures

Treatment for a scaphoid fracture depends on the location and severity of the break, the patient’s overall health, and activity level. Options include:

• Immobilization: For non-displaced fractures (where the bone has not moved out of place), immobilization with a cast or splint is typically recommended to keep the wrist stable and allow the bone to heal. This may involve wearing a cast for several weeks to months, depending on the fracture’s location and severity.
• Surgery: Displaced fractures (where the bone fragments have shifted) or fractures that do not heal with immobilization may require surgical intervention. Surgery typically involves the use of screws or pins to realign and stabilize the bone fragments, allowing for proper healing.
• Bone Grafting: In cases where the fracture is not healing (non-union) or if there is significant bone loss, a bone graft may be needed to promote healing. This procedure involves transplanting bone from another part of the body or using a donor bone to fill in gaps and support the fractured scaphoid.
• Physical Therapy: Following immobilization or surgery, a structured rehabilitation program focusing on stretching and strengthening exercises can help restore wrist mobility and function.
