Total Shoulder Replacement

Shoulder replacement, also known as shoulder arthroplasty, is a surgical procedure designed to relieve pain and restore function in a severely damaged or diseased shoulder joint. It involves replacing the damaged parts of the shoulder joint with artificial components, which can be made of metal, plastic, or ceramic materials.

The procedure is typically recommended for individuals with conditions such as severe arthritis, rotator cuff tears, or fractures that have resulted in significant shoulder joint damage. These conditions can cause chronic pain, stiffness, and limited mobility, significantly affecting a person's quality of life.

During the surgery, the surgeon makes an incision over the shoulder joint and removes the damaged portions of the joint, including the head of the humerus (upper arm bone) and sometimes the socket of the scapula (shoulder blade). These components are then replaced with artificial implants, which mimic the natural shape and function of the shoulder joint.

Shoulder replacement surgery can be either total, partial, or reverse, depending on the extent of joint damage. When it comes to shoulder replacement, total shoulder replacement means both the ball part of the upper arm bone (humerus) and the socket are replaced. On the other hand, partial replacement only involves replacing the ball part of the upper arm bone.

Following the procedure, patients undergo a rehabilitation program to regain strength, mobility, and function in the shoulder joint. Physical therapy exercises, pain management techniques, and a gradual return to daily activities are typically included in the recovery process.

While shoulder replacement surgery can significantly reduce pain and improve shoulder function, it is important to note that it is a major surgical procedure with potential risks and complications. It is crucial to consult with a qualified orthopaedic surgeon to determine if shoulder replacement is the appropriate treatment option for individual cases.

Shoulder Anatomy 

The shoulder is a complex joint that allows a wide range of motion and is essential for the function of the upper limb. It is formed by the articulation between three bones: the humerus (upper arm bone), the scapula (shoulder blade), and the clavicle (collarbone). The humerus has a rounded head that fits into a shallow socket called the glenoid fossa, which is part of the scapula. This articulation forms the glenohumeral joint, which is the main joint of the shoulder. The joint is stabilised by a group of ligaments, including the glenohumeral ligaments and the joint capsule.

In shoulder movement, the scapula plays an important role. It has a prominent ridge called the spine, which divides it into two regions: the supraspinous fossa and the infraspinous fossa. The scapula also has a bony projection called the acromion, which forms the highest point of the shoulder and articulates with the clavicle to form the acromioclavicular joint. The clavicle is an S-shaped bone that connects the scapula to the sternum (breastbone). It acts as a strut, providing support and stability to the shoulder joint. The clavicle articulates with the acromion at the acromioclavicular joint and with the sternum at the sternoclavicular joint.

Several muscles surround the shoulder joint and contribute to its movement. The rotator cuff muscles, including the supraspinatus, infraspinatus, teres minor, and subscapularis, help stabilise the joint and initiate shoulder movements. Other muscles, such as the deltoid, pectoralis major, and trapezius, provide additional strength and control during shoulder movements. In addition to bones and muscles, the shoulder joint contains several bursae, which are small fluid-filled sacs that reduce friction between tendons and bones. These bursae, such as the subacromial and subscapular bursae, help facilitate smooth movement of the shoulder.

Types of Shoulder Replacement Surgery 

There are several types of shoulder replacement surgery, each designed to address specific conditions and degrees of joint damage. The three primary types of shoulder replacement procedures are total shoulder replacement, partial shoulder replacement, and reverse shoulder replacement.

  • Total Shoulder Replacement - Total shoulder replacement, also acknowledged as total shoulder arthroplasty or shoulder total replacement, is the most common type of shoulder replacement surgery. It involves replacing both the head of the humerus (upper arm bone) and the socket (glenoid) with artificial components. During the procedure, the surgeon removes the damaged portions of the humeral head and glenoid, and then inserts a metal ball with a stem into the humerus. A plastic socket is implanted into the glenoid, which allows the metal ball to articulate smoothly. Total shoulder replacement is typically recommended for patients with severe arthritis or degenerative joint disease, where both the humeral head and the glenoid are affected. It can provide pain relief, restore shoulder function, and improve overall joint stability.
  • Partial Shoulder Replacement - Partial shoulder replacement, also known as hemiarthroplasty, is a surgical procedure where only the damaged humeral head is replaced, while the native glenoid is preserved. This procedure is typically used in cases where the glenoid is still healthy and functioning properly, while the humeral head is severely damaged due to conditions such as osteoarthritis or fractures. It involves removing the damaged humeral head and replacing it with a metal ball and stem component, similar to the total shoulder replacement. Partial shoulder replacement may be beneficial for patients who have intact rotator cuff tendons and a stable glenoid joint. It can provide pain relief, improve range of motion, and restore function in the shoulder joint.
  • Reverse Shoulder Replacement - Reverse shoulder replacement, also known as reverse total shoulder replacement or arthroplasty, is a specialised procedure primarily used for patients with certain specific conditions, such as massive rotator cuff tears, rotator cuff arthropathy, or failed previous shoulder surgeries. Unlike the traditional shoulder replacement procedures, the reverse shoulder replacement reverses the natural anatomy of the shoulder joint. It involves placing a metal ball component on the glenoid and a plastic socket component on the humerus. This reversal of the components changes the biomechanics of the shoulder, allowing the deltoid muscle to compensate for the lack of rotator cuff function.  The reverse shoulder replacement is designed to improve shoulder function in patients with a compromised or non-functioning rotator cuff. By relying on the deltoid muscle instead of the rotator cuff for movement, it can restore arm elevation and provide pain relief. This procedure is particularly beneficial for older patients or those with irreparable rotator cuff tears, as it relies less on intact tendons for shoulder stability.

It is important to note that while these are the primary types of shoulder replacement surgeries, there may be variations or combinations of these procedures depending on individual patient needs and surgeon preference. The choice of the most appropriate type of shoulder replacement surgery will depend on factors such as the specific condition, degree of joint damage, age, overall health, and the patient's goals and expectations. Consulting with an experienced shoulder replacement doctor is crucial to determine the most suitable approach and to discuss the potential risks, benefits, and expected outcomes of each type of shoulder replacement surgery.

Why Do You Need Shoulder Replacement Surgery?

Shoulder replacement surgery is typically recommended to individuals who have severe shoulder joint damage or conditions that cause chronic pain and limited mobility in the shoulder. Some of the common reasons for needing shoulder replacement surgery include:

  • Osteoarthritis - This is the most common reason for shoulder replacement surgery. Osteoarthritis is a degenerative joint disease that occurs when the cartilage that cushions the joints wears down over time, leading to pain, stiffness, and reduced range of motion in the shoulder.
  • Rheumatoid arthritis - This is an autoimmune disease that causes chronic inflammation in the joints, including the shoulder joint. Over time, the inflammation can lead to cartilage damage, joint deformity, and pain, necessitating shoulder replacement surgery.
  • Post-traumatic arthritis - This kind of arthritis occurs when the shoulder experiences a serious injury, like a broken bone or when it gets dislocated. The injury may disrupt the normal structure and function of the shoulder joint, leading to the development of arthritis and the need for surgical intervention.
  • Rotator cuff tear arthropathy - A rotator cuff tear is a common shoulder injury that can sometimes lead to a condition known as rotator cuff tear arthropathy. This occurs when a large, chronic rotator cuff tear causes the humeral head (upper arm bone) to move abnormally within the joint, resulting in pain, weakness, and degenerative changes that may necessitate shoulder replacement.
  • Avascular necrosis - Avascular necrosis occurs when the blood supply to the shoulder joint is disrupted, leading to the death of bone tissue. This can cause the joint to deteriorate and result in severe pain and functional impairment, requiring shoulder replacement surgery.
  • Severe shoulder fractures - In cases where a shoulder fracture is severe and cannot be effectively treated with conservative methods or internal fixation, shoulder replacement surgery may be necessary to restore function and reduce pain.

It is important for you to note that shoulder replacement surgery is typically considered when more conservative treatments, such as physical therapy, medications, and lifestyle modifications, have failed to provide sufficient relief or improve shoulder function. The decision to undergo shoulder replacement surgery is typically made after a thorough evaluation by a shoulder replacement doctor who considers the individual's specific condition, symptoms, and overall health.

Diagnosis Before A Shoulder Replacement Surgery 

Before a shoulder replacement surgery, several diagnostic procedures are typically performed to evaluate the condition of the shoulder joint and determine the need for surgery. These diagnostic steps may include:

  • Medical History
  • Physical Examination
  • X-rays 
  • Magnetic Resonance Imaging (MRI) 
  • Ultrasound
  • Computed Tomography (CT) Scan
  • Blood Tests
  • Arthroscopy

Based on the findings from these diagnostic procedures, along with the patient's symptoms and functional limitations, the shoulder specialist in Delhi will determine if shoulder replacement surgery is the appropriate treatment option.

Risks and Complications Associated with Shoulder Replacement Surgery

Shoulder replacement surgery is a common procedure performed to relieve pain and improve function in individuals with severe shoulder joint damage or conditions such as osteoarthritis, rheumatoid arthritis, or a significant shoulder fracture. While it is generally a safe procedure, like any surgery, there are risks and potential complications associated with shoulder replacement surgery. Some of these risks include:

  • Infection - Infections can occur after any surgical procedure, including shoulder replacement surgery. Antibiotics are typically administered before, during, and after the surgery to reduce the risk of infection. However, if an infection does develop, it may require additional treatment, such as antibiotics or, in severe cases, removal of the implant.
  • Blood clots - Surgery can increase the risk of blood clots forming in the veins of the legs, a condition known as deep vein thrombosis (DVT). If a blood clot travels to the lungs, it can cause a potentially life-threatening condition called a pulmonary embolism. Blood thinners and compression devices are commonly used to prevent blood clot formation after surgery.
  • Shoulder instability - In some cases, the new shoulder joint may become unstable, leading to a dislocation or subluxation. This can occur if the muscles, tendons, or ligaments around the joint are not adequately repaired or if there is improper implant positioning. Physical therapy and rehabilitation are crucial in reducing the risk of instability.
  • Nerve injury - During the surgery, nerves near the shoulder joint can be damaged, resulting in temporary or permanent loss of sensation or muscle weakness. Most nerve injuries improve over time, but in some cases, they may require additional treatment or intervention.
  • Loosening or wear of the implant - Over time, the artificial components of the shoulder joint replacement can loosen or wear out. This may lead to pain, reduced range of motion, and the need for a revision surgery to replace the worn-out components.
  • Allergic reactions - Although rare, some individuals may have an allergic reaction to the materials used in the shoulder replacement implants, such as metal alloys. Allergies can cause pain, swelling, or rash around the joint.
  • Persistent pain or stiffness - While shoulder replacement surgery is intended to relieve pain and improve joint function, some individuals may continue to experience persistent pain or stiffness after the procedure. This can be due to various factors, such as improper surgical technique, implant-related issues, or individual healing differences.

It is crucial to note that the risks and complications mentioned above are not exhaustive, and the likelihood of experiencing them varies from person to person. So, you should discuss these potential risks with your shoulder replacement doctor before undergoing shoulder replacement surgery and follow their post-operative instructions to minimise the risk of complications.

What After Total, Partial, or Reverse Shoulder Replacement Surgery

After undergoing total, partial, or reverse shoulder replacement surgery, the recovery and rehabilitation process is crucial for achieving the best possible outcome. Here are the general steps and considerations involved in the post-surgery period:

  • Hospital Stay - Following the surgery, you will typically spend a few days in the hospital for monitoring and initial recovery. Pain management, wound care, and physical therapy may begin during this time.
  • Pain Management - Pain medication will be prescribed to help manage any discomfort or pain you experience. Take the medication as your shoulder replacement doctor’s directions. 
  • Wound Care - Proper care of the surgical incision is essential to prevent infection. Keep the incision area clean and dry, and follow any specific instructions provided by your surgeon.
  • Immobilisation and Sling Use - Depending on the type of shoulder replacement, you may need to wear a sling or brace to support and protect the shoulder during the initial healing phase. The surgeon or physical therapist will advise you on how long to wear the sling and when you can start moving your arm.
  • Physical Therapy - Physical therapy is a crucial component of shoulder replacement recovery. It helps improve range of motion, strength, and function in the shoulder joint. Initially, therapy may focus on gentle exercises and passive movements to prevent stiffness and promote healing. As you progress, you'll gradually increase the intensity and complexity of exercises.
  • Rehabilitation Timeline - The duration of rehabilitation varies, but it typically lasts several months. The specific timeline depends on the type of surgery, your overall health, and how well you respond to therapy.
  • Home Exercises - In addition to attending formal physical therapy sessions, your therapist will likely provide you with exercises to perform at home. Consistently following the prescribed exercise regimen is crucial for achieving optimal results.
  • Lifestyle Modifications - During the recovery period, you may need to make certain modifications to your daily activities to protect the shoulder joint. Your healthcare provider or therapist will provide guidance on the appropriate movements, weight restrictions, and activities to avoid.
  • Follow-up Appointments - Regular follow-up appointments with your surgeon will be scheduled to monitor your progress, assess range of motion, and address any concerns or complications that may arise.

It is important to note that every individual's recovery process is unique, and the above steps may be tailored to your specific situation. Always follow your shoulder replacement specialist’s instructions and communicate any issues or difficulties you experience during the recovery period.
