Total Shoulder Endoprosthesis

Overview

Shoulder replacement surgery is a highly technical procedure; each step plays a critical role in the outcome. After administering anesthesia, an incision is made across the front of the shoulder from the middle of the collarbone to the middle of the arm bone. This allows access to the joint without damaging the important deltoid or pectoralis muscles that are responsible for a significant portion of the shoulder's power. Scar tissue that may be restricting the movement of the muscles and other tissues near the shoulder are removed hence increase mobility. The tendon of the subscapularis muscle is removed to gain access to the joint and released circumferentially to restore its length and mobility. The arthritic humeral head (ball of the joint) is removed and the bone spurs are removed to prepare the bone for the humeral prosthesis.

Who May Need This

Patients who may discuss total shoulder endoprosthesis with a qualified orthopedic surgery specialist include those with relevant symptoms or conditions that have not responded to conservative approaches. Eligibility can only be determined through a thorough medical evaluation.

When It May Be Recommended

This procedure may be considered when conservative treatments have not provided adequate relief, when diagnostic tests indicate it may be appropriate, or when symptoms significantly impact quality of life. The final decision depends on individual evaluation by a specialist.

Diagnosis and Evaluation

Before treatment, your specialist may recommend a complete medical history review, physical examination, relevant imaging or laboratory tests, and possibly specialist consultations. A second opinion may be valuable before making treatment decisions.

How It Is Performed

A hemiarthroplasty may be performed, if the glenoid socket is unaffected or is in other selected conditions. In a cuff tear arthropathy, a hemiarthroplasty (replacing the humeral joint surface only) is usually selected because the anatomy does not favor the use of a glenoid prosthesis. The humeral component is made of metal and is usually press fit, but sometimes cemented, into the shaft of the bone of the humerus. If the glenoid is affected and conditions do not favor the insertion of a glenoid component, a non-prosthetic glenoid arthroplasty may be performed along with a humeral hemiarthroplasty. In this procedure, the glenoid shape and orientation are corrected without inserting a glenoid prosthesis. The prosthetic ball of the humeral component articulates with the reshaped bony socket of the glenoid. This procedure may be selected when the patient is interested in performing heavy activities that might jeopardize the fixation of a polyethylene glenoid component.

Preparation

Preparation typically includes completing all pre-procedure testing as directed, reviewing medications with your doctor, following fasting instructions if applicable, arranging for a companion if traveling abroad, and planning for recovery time.

Benefits and Expected Goals

This treatment aims to address the underlying condition and improve quality of life in appropriately selected patients. Outcomes vary by individual. Your specialist can discuss realistic goals based on your specific case.

Risks and Possible Complications

In a total shoulder joint replacement, the glenoid bone is shaped and oriented as in the non-prosthetic glenoid arthroplasty and then covered with a polyethylene glenoid component, as seen in the figure. A small amount of bone cement is used to hold the artificial glenoid socket in place. At the conclusion of any of these procedures, the subscapularis tendon is securely repaired to the bone. This repair requires protection from active use for at least 6 weeks while it is healing.

Recovery, Follow-up & Aftercare

Recovery varies by patient and depends on the specific procedure performed. Your medical team will provide detailed aftercare instructions, including activity restrictions, follow-up appointments, and warning signs to watch for.

Medical Tourism Planning

When planning treatment abroad, choose a JCI or ISO-accredited hospital. Verify the specialist's credentials and experience. Request a written treatment plan and cost estimate. Arrange follow-up care with your local doctor before traveling. Consider medical travel insurance.

Estimated Cost Factors

Cost depends on the country and hospital chosen, specialist fees, procedure complexity, length of stay, and any additional diagnostics or implants required. Prices are estimates — always request a personalized written quote.

Choosing a Hospital or Specialist

Verify hospital accreditation (JCI, ISO, or national equivalent). Confirm the specialist's board certification, experience with this specific procedure, and patient outcomes. Ensure international patient services are available.

Alternatives

Depending on the diagnosis, alternatives may include observation and monitoring, medication management, lifestyle modifications, non-surgical treatments, or different procedure approaches. Discuss all options with your healthcare provider.

Questions to Ask Your Doctor

- Is this procedure recommended for my specific case? - What are the risks and potential complications in my situation? - What alternatives are available? - How many similar procedures have you performed? - What is included in the cost estimate? - What follow-up care will I need after returning home? - What warning signs should I watch for during recovery? - How long before I can return to normal activities? Anesthetic A general anesthetic or a brachial plexus nerve block can be used for a shoulder joint replacement surgery. A brachial plexus block can provide anesthesia for several hours after the surgery. Preferences are discussed with the anesthesiologist before surgery.
