Total Shoulder Endoprosthesis
This page provides general information about total shoulder endoprosthesis — what it involves, who it may help, how it is performed, and what to consider when planning treatment abroad. This information is for educational purposes only. Final medical advice must come from a qualified healthcare professional who has evaluated your individual case.
Overview
A total shoulder endoprosthesis is an artificial joint implanted to replace a worn or damaged shoulder. “Endoprosthesis” simply means a prosthesis placed inside the body; “total” means both sides of the joint are resurfaced — the ball at the top of the arm bone (humerus) and the socket (glenoid) on the shoulder blade. This distinguishes it from a partial (hemi) prosthesis that replaces only the ball.
The most common design recreates the natural anatomy: a metal ball, mounted on a stem or fixed directly to the bone (stemless), articulates with a plastic socket component. The aim is to relieve the pain of an arthritic shoulder and restore comfortable, functional movement.
This page is an educational overview only. It is not medical advice, and no surgical outcome can be guaranteed. Whether a total shoulder endoprosthesis is right for you can only be decided after evaluation by a qualified orthopaedic shoulder surgeon.
Who May Need This
A total shoulder endoprosthesis is usually considered for adults with advanced shoulder arthritis — most often primary osteoarthritis, but also rheumatoid arthritis or avascular necrosis — with a reasonably intact rotator cuff and good enough socket bone to hold the components. Typical symptoms are deep, aching shoulder pain, night pain, grinding, and loss of motion despite non-surgical care.
When the rotator cuff is severely torn, a different design (a reverse prosthesis) is generally preferred instead. Candidacy depends on the joint damage, rotator cuff, bone quality, overall health, and goals. Only a surgeon can determine eligibility after a full assessment.
When It May Be Recommended
Replacement may be recommended when pain and stiffness persist despite physiotherapy, activity changes, anti-inflammatory medication, and injections, and imaging confirms significant joint destruction. Difficulty sleeping and with everyday reaching tasks are common triggers for proceeding.
The decision weighs the benefits against the risks and considers the state of the rotator cuff and bone, which determine whether an anatomic total prosthesis is suitable. The final recommendation depends on individual evaluation.
Diagnosis and Evaluation
Evaluation includes a history and examination of shoulder motion, strength, and rotator-cuff function. X-rays reveal the arthritis and bone shape, and CT is often used to assess the glenoid bone stock and plan the socket component, while MRI can evaluate the rotator cuff.
Your general health, skin, and any sources of infection are reviewed, along with blood tests and a medication review to plan anaesthesia and clot prevention. A second opinion can be valuable before deciding.
Treatment Options
Options range from least to most invasive: non-surgical care (physiotherapy, activity modification, medication, injections); a hemiprosthesis that replaces only the ball, used in selected cases; an anatomic total endoprosthesis that also resurfaces the socket, giving more reliable pain relief when the cuff is intact; and a reverse prosthesis when the rotator cuff is deficient.
Within total replacement, the surgeon chooses between stemmed and stemless humeral designs based on bone quality. Your surgeon will explain which option fits your shoulder.
How It Is Performed
The operation is performed under general anaesthesia, usually with a nerve block. Through an incision at the front of the shoulder, the surgeon removes the arthritic humeral head and prepares the bone for the ball component — either on a stem within the arm bone or fixed directly to the surface (stemless). The glenoid socket is resurfaced with a plastic component.
Soft tissues are balanced, and the joint is tested for smooth motion and stability before closing. The procedure commonly takes a couple of hours. The choice of components influences the rehabilitation plan.
Preparation
Preparation typically includes pre-operative tests, treating any infections, optimising conditions such as diabetes, and reviewing medications — especially blood thinners — with your doctor. Stopping smoking aids healing.
Arrange help at home, since the arm will be in a sling and limited early on, and prepare loose, easy-to-wear clothing. If travelling abroad, allow for the recommended in-country stay and bring your imaging and records.
Benefits and Expected Goals
The most reliable benefit is pain relief, with improved movement and a return to daily activities. Resurfacing the socket in a total prosthesis generally provides more dependable pain relief than replacing the ball alone.
Benefits vary by individual and depend on the rotator cuff and committed rehabilitation. Motion improves but may not be completely normal. Realistic expectations give the best outcomes.
Risks and Possible Complications
Total shoulder replacement is generally safe, but as major surgery it carries risks.
- Infection, which can be serious and may require further surgery
- Loosening or wear of the glenoid (socket) component over time
- Nerve injury causing numbness or weakness in the arm or hand
- Instability or dislocation of the prosthesis
- Fracture of the bone during or after surgery
- Rotator-cuff failure, stiffness, or blood clots
Your surgeon will explain the risks specific to your health. Report fever, spreading redness, drainage, or new arm numbness or weakness promptly.
Recovery, Follow-up & Aftercare
Recovery varies by patient. The arm is protected in a sling at first, with gentle guided movements starting early and strengthening added later under a physiotherapist’s direction. Everyday use returns gradually over weeks to months.
Following the rehabilitation programme and any activity limits protects the components. Attend follow-up appointments and X-rays, and arrange rehabilitation and monitoring with your local doctor before travelling home.
Medical Tourism Planning
If you are considering a shoulder endoprosthesis abroad, choose a JCI- or ISO-accredited hospital with a shoulder surgeon experienced in total shoulder arthroplasty. Ask about implant options (including stemless designs), infection rates, and how complications and follow-up would be handled.
Plan for the in-country stay your team recommends for surgery and early rehabilitation, arrange ongoing physiotherapy and follow-up at home, consider medical travel insurance, and request a written treatment plan and cost estimate before you travel.
Estimated Cost Factors
The cost depends on the country and hospital, surgeon’s fees, the prosthesis chosen (stemmed or stemless, and the socket component), anaesthesia, length of stay, and physiotherapy. Complexity and any complications affect the total.
Many international destinations offer joint replacement at a fraction of typical US prices, but figures vary widely by case. Online prices are only estimates — always request a personalized written quote for your specific situation before deciding.
Choosing a Hospital or Specialist
Look for recognised accreditation (JCI, ISO, or a strong national equivalent) and a surgeon with dedicated shoulder experience and a good volume of total shoulder procedures. Confirm board certification and ask about implant options and infection prevention.
Ask about international patient services, interpreter support, physiotherapy facilities, and the follow-up plan. Transparent written cost and treatment plans and clear communication are signs of a quality programme.
Alternatives
Alternatives depend on the diagnosis. They include non-surgical management (physiotherapy, activity modification, medication, injections), a hemiprosthesis in selected cases, and a reverse prosthesis when the rotator cuff is deficient.
Each option has different benefits, risks, and recovery. Discuss all of them with your surgeon so the plan fits your shoulder, rotator cuff, and goals.
Questions to Ask Your Doctor
- Is an anatomic total prosthesis suitable for me, or would a reverse design be better?
- Would you use a stemmed or stemless implant, and why?
- Will the socket be resurfaced, and how does that affect my outcome?
- How many total shoulder procedures do you perform, and what are your outcomes?
- What are the specific risks in my case, and how do you prevent infection?
- What does rehabilitation involve, and how long should I stay in-country?

Frequently Asked Questions
An endoprosthesis is an artificial joint implanted inside the body. A total shoulder endoprosthesis replaces both surfaces of the shoulder — the ball on the arm bone and the socket on the shoulder blade — with prosthetic components, as opposed to a partial (hemi) prosthesis that replaces only the ball. It is another term for total shoulder replacement.
A stemmed prosthesis anchors a metal ball on a stem placed down the arm bone, while a stemless design fixes the ball directly to the top of the bone, preserving more native bone. Stemless implants suit patients with good bone quality and may simplify any future revision; stemmed designs are versatile and long established. Your surgeon selects based on your bone and anatomy.
Many shoulder prostheses function well for 10–20 years or longer, though results vary and no implant lasts forever. Wear or loosening of the socket component and infection are the usual reasons for eventual revision. Following activity guidance and attending follow-ups helps protect the result.
In a true total prosthesis the socket (glenoid) is resurfaced, usually with a plastic component, which tends to give better pain relief than leaving the natural socket. In some cases — poor socket bone or a deficient rotator cuff — the surgeon may choose a different strategy. This is decided from your imaging.
Yes. Choose a JCI- or ISO-accredited hospital with a shoulder surgeon experienced in total shoulder arthroplasty, plan enough in-country time for early rehabilitation, and arrange physiotherapy and follow-up with your doctor at home. Always request a personalized written quote and treatment plan.
