Reconstructing the Elbow: Surgery for Broken Elbow Fractures

This surgery is performed to treat complex elbow fractures involving multiple bones or a dislocated joint. Typically, this includes a fracture of the proximal ulna along with a radial head fracture or dislocation. These injuries require precise surgical intervention to restore the elbow's stability and function. The procedure often involves using metal plates, screws, or other devices to stabilize the fractures, followed by a comprehensive rehabilitation program to restore strength and mobility. This approach aims to achieve the best possible recovery and prevent long-term complications.

What is an elbow fracture?

An elbow fracture is a break or crack in one or more of the bones that make up the elbow joint. In simpler terms, it means that one of the bones in your elbow has been broken. The elbow is a hinge joint where three bones meet: the humerus (upper arm bone), the radius, and the ulna (the two bones in the forearm). An elbow fracture can occur in any of these bones. 

Elbow fractures are often caused by falls onto an outstretched arm or direct blows to the elbow area. They can be very painful and may cause swelling, bruising, and difficulty moving the arm. In easy language, an elbow fracture is a broken bone in your elbow, usually caused by falling on your arm or hitting your elbow really hard. It can make your elbow hurt a lot, swell up, and make it difficult to move your arm. For proper treatment, consider consulting a hospital for joint surgery.

Anatomy 

The elbow is a joint composed of three bones:

1. The humerus (upper arm bone)
2. The radius (forearm bone on the thumb side)
3. The ulna (forearm bone on the pinky side)

The elbow functions like a hinge, allowing the arm to bend and straighten. It also enables forearm rotation, letting you turn your palm up (as if accepting change) or down (as if typing or playing the piano).

Each of the three bones contributes to the elbow joint:

• The distal humerus is the lower end of the humerus, forming the upper part of the elbow. It acts as the spool around which the forearm moves.
• The radial head is the knobby end of the radius. It moves along the front of the distal humerus when you bend your arm and rotates around the ulna when you turn your wrist.
• The olecranon is part of the ulna that cups the lower end of the humerus, forming a hinge for elbow movement. This bony point is easily felt beneath the skin due to a thin tissue layer covering it.

The elbow is stabilized by its bony structure, ligaments, tendons, and muscles. Additionally, three major nerves cross the elbow joint.
 

Types Of Elbow Fracture 

There are three main types of elbow fractures:

1. Olecranon fractures: The olecranon is the pointy tip of your elbow and part of the ulna, one of the two forearm bones. It is particularly susceptible to fractures because it lacks muscle protection.

2. Radial head fractures: The radial head connects to the humerus (upper arm bone). This type of fracture typically occurs when someone tries to break a fall with their arm, causing the radial head to push into the humerus and fracture.

3. Distal humerus fractures: The distal humerus links the shoulder to the elbow. Although not common, these fractures can happen due to trauma or falling onto a bent elbow.

Causes 

Here are some of the common causes of elbow fractures:

1. Falls: Falls onto an outstretched arm or elbow are one of the most frequent causes of elbow fractures. This can happen during sports, activities, or simply tripping and falling.
2. Direct Blow or Impact: A direct blow or impact to the elbow, such as from a motor vehicle accident, sports injury, or a falling object, can cause the bones in the elbow to break.
3. Osteoporosis: People with osteoporosis(a condition that causes bones to become weak and brittle) are at a higher risk of sustaining an elbow fracture, even from a minor fall or bump.
4. Overuse Injuries: Repetitive stress or overuse injuries, commonly seen in throwing sports like baseball or weight-lifting, can lead to small cracks or fractures in the elbow bones over time.
5. Trauma: Severe trauma, such as from a car accident or a high-impact fall, can cause complex elbow fractures that may involve multiple bones.
6. Medical Conditions: Certain medical conditions, like bone cancer or infections, can weaken the bones and make them more susceptible to fractures.

Prompt medical attention is crucial for proper diagnosis and treatment of elbow fractures to ensure proper healing and regain full mobility.

Symptoms 

While some elbow fractures cause intense, sudden pain and noticeable deformity, others may present with more subtle symptoms. Common signs of a fractured elbow include:

• Swelling near the back of the elbow
• Elbow stiffness
• Bruising around the elbow or arm
• Numbness or weakness in the hand or fingers
• Tenderness when touched
• Pain during forearm rotation
• A sensation that the elbow might "pop out" of the joint

Treatment

The type of elbow fracture treatment depends on the specific condition of your fracture. There are two options for treating an elbow fracture:- Surgical Treatment and Non-Surgical Treatment.

Nonsurgical Treatment

If the bone fragments are not displaced, a fracture can sometimes be treated with a splint to hold the elbow in place during healing. During the healing process, your doctor will take frequent X-rays to ensure the bone remains in place.

Typically, you will wear a splint for about six weeks before starting gentle motion exercises. If the fracture shifts out of position during this time, surgery may be necessary to realign the bones.

Surgical Treatment

Surgery is typically necessary for olecranon fractures when:

• The bones are displaced.
• Bone fragments have punctured the skin (open fracture).

The surgical procedure involves realigning the broken pieces of bone and securing them to prevent movement during the healing process. 
Open fractures, due to the higher risk of infection, are treated with urgency, often within hours of diagnosis. Patients receive intravenous antibiotics in the emergency room and may get a tetanus shot. During surgery, the injury site and bone surfaces are thoroughly cleaned, and the bone is usually repaired in the same operation.

Prognosis for Elbow Fracture

The prognosis for an elbow fracture varies depending on the type and severity of the fracture, as well as the patient's overall health and age. Generally, with appropriate treatment, most people can expect a good recovery.

• Minor Fractures: These often heal well with non-surgical treatments such as splinting, rest, and physical therapy. Patients can usually regain full function within a few months.
• Moderate to Severe Fractures: These may require surgical intervention to properly align and stabilize the bones. Recovery might take longer, often involving several months of rehabilitation to restore strength and mobility.
• Complications: In some cases, complications such as stiffness, arthritis, or nerve damage can occur. These complications may affect long-term function and may require additional treatment or surgery.
• Rehabilitation: Physical therapy is often crucial in the recovery process, helping to restore range of motion, strength, and flexibility. Following the rehabilitation plan prescribed by a healthcare provider can significantly improve outcomes.

Overall, the prognosis for an elbow fracture is generally favorable, particularly with appropriate medical intervention and diligent rehabilitation efforts by Orthopedic Surgeons. Patients are advised to follow their healthcare provider's guidance closely and engage in recommended exercises and therapies to optimize their recovery.
