Total Elbow Replacement (TER): Comprehensive guide

The elbow is one of the most intricate joints in the human body, playing a pivotal role in the movement and functionality of the arm. It is where the humerus (upper arm bone) meets the radius and ulna (forearm bones), allowing for both bending and rotation of the forearm. Over time, due to various reasons, this joint may deteriorate or get damaged, necessitating surgical intervention. One such intervention is the Total Elbow Replacement (TER).

Total Elbow Replacement (TER)

Total Elbow Replacement, commonly referred to as TER, is a surgical procedure wherein the damaged parts of the humerus and the ulna are replaced with artificial components. These components are typically made of metal and plastic. The primary goal of TER is to restore function, alleviate pain, and improve the range of motion in individuals with severely damaged elbow joints.

Elbow Joint Anatomy

The elbow joint is a hinge joint, but it also allows for rotational movements. It is formed by three bones:

• Humerus: The long bone of the upper arm.
• Radius: One of the two forearm bones, positioned on the thumb side.
• Ulna: The other forearm bone, which runs parallel to the radius and is on the side of the little finger.

These bones are held together by ligaments, tendons, and muscles, ensuring stability and facilitating movement. The surface of these bones, where they meet to form the joint, is covered with articular cartilage. This cartilage ensures smooth movement by reducing friction. However, diseases or injuries can damage this cartilage, leading to pain and restricted movement, which may necessitate a Total Elbow Replacement.

Indications for Total Elbow Replacement (TER)

Total Elbow Replacement (TER) is a surgical procedure that aims to restore the function and alleviate pain in the elbow joint. While it's not the first line of treatment for most elbow conditions, there are specific scenarios where TER becomes the most suitable option. Here are the primary indications:

1. Severe Arthritis
   • Osteoarthritis (OA): This is a degenerative joint disease that affects the cartilage, which acts as a cushion between the bones of the elbow joint. As the cartilage wears away, the bones begin to rub against each other, leading to pain, swelling, and reduced motion. In severe cases where non-surgical treatments fail to provide relief, TER may be recommended.
   • Rheumatoid Arthritis (RA): RA is an autoimmune disorder where the body's immune system attacks the synovium (the lining of the membranes that surround the joints). This can lead to inflammation and damage to the joint cartilage and bones. When the damage is extensive and other treatments are ineffective, TER can be a viable solution.
2. Complex Elbow Fractures: In situations where the elbow has sustained a severe fracture, especially in older patients where the bones might not heal properly or are too fragmented, TER can be an option. This is particularly true if the fracture involves the joint surface, making it challenging to restore the joint's natural anatomy through other surgical methods.
3. Failed Previous Elbow Surgeries: Sometimes, patients might have undergone surgeries to treat elbow conditions, but the outcome might not be as expected. This could be due to persistent pain, instability, or the development of post-surgical complications. In such cases, if the joint's condition deteriorates further, a TER might be considered to rectify the issues and restore function.
4. Tumor Resection: In rare cases, tumors (benign or malignant) might develop in or around the elbow joint. If a significant portion of the joint needs to be removed to excise the tumor, a TER can be performed to replace the resected joint and maintain its function.

It's essential to understand that the decision to undergo a Total Elbow Replacement is multifaceted. It depends on the patient's overall health, the severity of the joint damage, age, activity level, and the potential risks and benefits of the surgery. Always consult with an orthopedic surgeon to determine the best course of action.

Preoperative Evaluation for Total Elbow Replacement (TER)

Before undergoing a Total Elbow Replacement, it's crucial to conduct a thorough preoperative evaluation. This assessment ensures the patient is a suitable candidate for the surgery and helps in planning the procedure. Here's what the evaluation typically entails:

1. Medical History and Physical Examination:
   • Medical History: The surgeon will gather detailed information about the patient's general health, previous surgeries, allergies, medications, and any chronic conditions like diabetes, heart disease, or hypertension. Understanding the patient's medical background helps in assessing the risks associated with the surgery and anesthesia.
   • Physical Examination: The orthopedic surgeon will assess the elbow's range of motion, strength, stability, and the location and intensity of pain. This examination provides insights into the extent of joint damage and helps in surgical planning.
2. Imaging Studies:
   • X-rays: These are the primary imaging studies used to evaluate the elbow joint. X-rays can reveal the extent of joint damage, bone spurs, and the narrowing of the joint space, which are indicative of arthritis or other degenerative conditions.
   • MRI (Magnetic Resonance Imaging): MRI provides detailed images of soft tissues, including ligaments, tendons, and cartilage. It can be particularly useful in assessing the condition of the cartilage and identifying any soft tissue abnormalities.
   • CT (Computed Tomography) Scans: CT scans offer cross-sectional images of the elbow, which can be especially helpful in evaluating complex fractures or planning for the placement of the prosthetic components during TER.
3. Blood Tests and Other Relevant Investigations:
   • Blood Tests: These are essential to assess the patient's overall health. Common tests include Complete Blood Count (CBC), Blood Glucose Levels, and tests for kidney and liver function. These tests can identify potential issues that might complicate the surgery or the recovery process.
   • Joint Fluid Analysis: In some cases, a sample of the fluid from the elbow joint might be taken to check for signs of infection or other conditions like gout.
   • Cardiac and Pulmonary Evaluation: For patients with a history of heart or lung conditions, additional tests like an Electrocardiogram (ECG) or a chest X-ray might be recommended to ensure they are fit for surgery.

The preoperative evaluation is a critical step in the surgical process. It not only determines the patient's suitability for TER but also provides valuable information that aids in surgical planning and postoperative care.

Choosing the Right Prosthesis for Total Elbow Replacement (TER)

Selecting the appropriate prosthesis is a pivotal decision in the TER process. The choice can influence the surgery's success, the joint's longevity, and the patient's postoperative quality of life. Here's a breakdown of the considerations:

1. Types of Elbow Prostheses:
   • Linked Prosthesis: This design connects the humeral and ulnar components, ensuring they move together. The linkage provides stability but may limit some natural movement.
   • Unlinked Prosthesis: In this design, the humeral and ulnar components are separate. While it allows for more natural movement, there's a higher risk of the components becoming dislocated if the surrounding soft tissues don't provide adequate support.
   • Semi-constrained Prosthesis: This is a middle-ground design, offering a balance between the linked and unlinked designs. It provides stability while still allowing a good range of motion.
2. Materials Used:
   • Metal: Common metals used include titanium and cobalt-chromium alloys. They are durable and can withstand the mechanical stresses of joint movement.
   • Plastic (Polyethylene): This material is often used for the bearing surface because of its smoothness and ability to reduce friction.
   • Ceramic: Less common than metal and plastic, ceramic is biocompatible and wears slowly. It's sometimes used in younger patients due to its longevity.
3. Factors Influencing Prosthesis Choice:
   • Patient's Age: Younger patients might benefit from more durable materials or designs that can withstand active lifestyles.
   • Activity Level: Active individuals might require a prosthesis that can handle more stress and strain.
   • Bone Quality: The quality and quantity of the patient's bone can influence the type of prosthesis and fixation method (cemented vs. non-cemented).
   • Joint Stability: If the ligaments around the elbow are damaged or weak, a linked or semi-constrained prosthesis might be more suitable.
   • Surgeon's Experience: The surgeon's familiarity and success with a particular type of prosthesis can influence the choice.
   • Expected Postoperative Range of Motion: Some prostheses might offer a better range of motion than others, influencing the choice based on the patient's needs and expectations.

The choice of prosthesis is a collaborative decision between the surgeon and the patient, taking into account the patient's unique circumstances and the surgeon's expertise. Proper selection can significantly impact the surgery's success and the patient's postoperative quality of life.
