Wrist Open Reduction and Internal Fixation

What is Open Reduction and Internal Fixation of the Wrist?

Open reduction and internal fixation of the wrist is a surgical technique employed for the treatment of severe wrist fractures to restore normal anatomy and improve range of motion and function.

A wrist fracture refers to a break in one or more bones in the wrist. The most common sites of fracture in the wrist are the radius (the large forearm bone) and the scaphoid (one of the small hand bones).

The wrist is comprised of two bones in the forearm (the radius and the ulna) and 8 small bones present in your hand. The bones meet to form multiple large and small joints.

Causes of Wrist Fractures

Wrist fractures can be caused due to a fall on an outstretched arm or from injury due to accidents such as a motor vehicle accident or workplace injuries. A wrist fracture is more common in people with osteoporosis, a condition marked by brittleness of the bones.

Signs and Symptoms of Wrist Fractures

Signs and symptoms of wrist fractures include:

  • Severe pain
  • Swelling
  • Tenderness
  • Bruising
  • Deformity of the wrist

Diagnosing Wrist Fractures

Your doctor will diagnose a wrist fracture by reviewing your signs and symptoms and performing a thorough physical examination. Your physician will:

  • Inspect to see any cuts from the injury as bone fragments can cut through the skin and create lacerations.
  • Palpate your arm to determine areas of tenderness as they can indicate injuries or broken bones.
  • Check your pulse at the wrist to ensure good blood flow via the forearm to your hand.
  • Check your fingers and wrist for proper hand movement as injury to nerves may cause weakness and numbness of the hand and wrist.

Your doctor will typically order an X-ray of the wrist or forearm to detect a broken or displaced bone. Sometimes, a computed tomography (CT) scan may be required to get a detailed view of the fractured fragments as well as injuries to soft tissues.

Preparation for Wrist Open Reduction and Internal Fixation

Prior to open reduction and internal fixation of the wrist fracture, you may have:

  • Physical exam to inspect blood circulation and nerves affected by the fracture
  • X-ray, CT scan, or MRI scan to assess surrounding structures and broken bone
  • Blood tests
  • Depending on the type of fracture you have sustained, you may be given a tetanus shot if you are not up to date with your immunization
  • A discussion with an anesthesiologist to determine the type of anesthesia you may undergo
  • A discussion with your doctor about the medications and supplements you are taking and if any should be stopped
  • A discussion about the need to avoid food and drink past midnight the night prior to your surgery

Procedure for ORIF of the Wrist

Open reduction and internal fixation is the procedure employed most often to treat displaced wrist fractures.

The surgery is performed under sterile conditions in the operating room under general or regional anesthesia.

  • After sterilizing the affected area, your surgeon will make an incision around the wrist.
  • Your surgeon will locate the fracture by carefully sliding in between the muscles of the wrist.
  • The surfaces of the fractured bone are thoroughly cleaned out.
  • After carefully visualizing the fracture, the bone fragments are first repositioned (reduced) into their normal alignment.
  • The fragments of bone are then held in place with wires, screws, pins, or metal plates attached to the outer surface of the bone.
  • After securing the bone, the incisions are closed by suturing or staples and covered with sterile dressings. A splint will also be applied.

Postoperative Care

You may have some pain after the procedure and medication will be prescribed to keep you comfortable. After surgery, your arm will be placed in a short splint for support and protection. Your doctor will provide instructions on dressings and incision care.

Physiotherapy is suggested to prevent arm stiffness, strengthen muscles, and restore range of motion. You will also be advised on a healthy diet and supplements high in vitamin D and calcium to promote bone healing.

Depending on your health condition and the extent of the injury, you may be able to go home the same day with scheduled follow-up appointments for monitoring progress and for stitches or staple removal if necessary. Your doctor will order X-rays to monitor healing throughout your treatment.

Risks and Complications

As with any surgery, some of the potential risks and complications of open reduction and internal fixation of wrist fractures may include:

  • Bleeding
  • Swelling
  • Infection
  • Pain
  • Anesthetic complications
  • Damage to nerves and blood vessels
  • Hardware irritation
  • Fracture nonhealing
  • Broken hardware
  • Repeat surgery
