Reverse shoulder arthroplasty | Solution to complex problems

Reverse shoulder arthroplasty is a very successful operation that has become extremely popular worldwide in recent years, with very encouraging results. In reverse arthroplasty, the replacement of worn surfaces is reversed relative to normal shoulder anatomy and anatomical arthroplasty. The indications for this operation have expanded dramatically in recent years, with the result that the inversion provides a solution to many complex problems.

What is reverse shoulder arthroplasty | Rationale

Reverse shoulder arthroplasty was developed in the 80s as a solution for rotator cuff arthropathy in older patients. Today, due to its excellent results, it has established itself as the treatment of choice not only for arthritis and rotator cuff arthropathy, but for a number of problems around the shoulder.

Reverse vs Anatomic Shoulder Arthroplasty

The National Registries report a 10-year survival rate of reverse arthroplasty for rotator cuff arthropathy of 94%. The increasing surgical experience with the reverse prosthesis and the subsequent reduction in complications has led in recent years to a spectacular expansion of the relevant indications. According to the Australian Joint Registry, the percentage of shoulder arthroplasties that are reverse has skyrocketed from 42.2% in 2009, to approximately 77.9% in 2018.

There are 2 main types of shoulder arthroplasty. Anatomic Shoulder Arthroplasty involves replacing the head of the humerus with a metal prosthesis and replacing the shoulder blade with a plastic prosthesis. Anatomic arthroplasty is performed in younger patients with an intact rotator cuff.

Reverse Shoulder Arthroplasty is performed in patients with arthritis, rotator cuff arthropathy, significant rotator cuff tears, humeral head fractures that are not amenable to internal fixation. In reverse shoulder arthroplasty, the head and concave surface ("cup") are positioned in reverse of normal (glenosphere on the glenoid and concave surface on the humerus).

Other types of shoulder arthroplasty include resurfacing, as well as shoulder hemiarthroplasty.

In reverse arthroplasty, the replacement of worn surfaces is reversed relative to the normal anatomy of the shoulder. While anatomic arthroplasty replicates the normal anatomy, reverse arthroplasty follows a non-anatomic philosophy, with reverse replacement of worn articular surfaces.

The head of the humerus is replaced with a curved prosthesis (cup), while the humerus is replaced with a spherical prosthesis (glenosphere). In this way, the "lever arm" of the shoulder joint is restored, and the patient is able to raise his arm using only the deltoid, without needing the support of the rotator cuff.

Reverse shoulder arthroplasty | Indications

Given the explosion in popularity of reverse arthroplasty, it is not surprising that the indications for placement of this prosthesis have expanded dramatically in recent years. These indications include:

  • Osteoarthritis
  • Cuff arthropathy
  • Massive irreparable rotator cuff tears
  • Trauma – proximal humeral fractures, either acutely, or secondarily.
  • Proximal humerus fracture malunion
  • Proximal humerus fracture nonunion
  • Rheumatoid arthritis
  • Avascular necrosis (AVN)
  • Post-traumatic arthritis
  • Failed rotator cuff repair
  • Failed ORIF

Revision shoulder arthroplasty | Causes

A shoulder operation has failed when the results do not meet the expectations of the patient and the surgeon. Failure can result from a number of causes, including stiffness, weakness, instability, pain, or failure to heal, as well as complications, such as periprosthetic infection or nerve injury. Every surgery comes with a risk of failure or post-operative complications, whether it is for a shoulder dislocation, rotator cuff tear, arthritis or fracture.

When a shoulder surgery fails or presents with problems, the patient should consult with a experienced surgeon in the evaluation and management of these conditions. Although pain may seem to be the main problem, it is important to determine the possible mechanical causes of the patient issues, since a mechanical cause can be repaired and reversed.

Before making the final decision to surgically revise a shoulder arthroplasty, it is important to determine the nature of the patient's problems. Common causes of shoulder arthroplasty failure include:

  • Periprothetic infection
  • Periprothetic fractures
  • Adverse reaction to polyethylene or cement (PMMA, polymethylmethacrylate)
  • Stiffness
    • Bad rehabilitation
    • Extra bone - osteophytes not removed, inadequate soft tissue release
    • Tuberosity malunion
    • Joint overstuffing
  • Instability
    • Anterior instability
      • subscapularis deficiency 
      • too much glenoid anteversion
      • tuberosity malunion
      • supra/infraspinatus deficiency 
      • problem in humeral anteversion or offset
      • glenoid bone defect
    • Posterior instability
      • glenoid retroversion
      • posterior cuff deficiency
      • problem in humeral retroversion or offset
      • glenoid bone defect
    • Superior instability
      • cuff deficiency
      • coracoacromial arch
  • Nerve injury
  • Humeral implact
    • malposition
    • loosening
  • Glenoid
    • bone erosion (hemiarthroplasty)
    • malposition
    • loosening

Reverse arthroplasty provides a solution to the most common problems that an anatomical arthroplasty or a hemiarthroplasty can bring about over time, such as the gradual erosion of the glenoid (glenoid wear), or the secondary rotator cuff deficiency, which are also the most frequent reasons for revision. Also, rTSA is the treatment of choice in cases of failure of previous surgery, such as arthroscopy for tendon suturing, or failure of fixation of a humeral head fracture.

Shoulder arthroplasty infection is a difficult case, often requiring a 1- or 2-stage revision. The first stage usually involves removal of the previous prostheses and placement of a cement spacer, often impregnated with appropriate antibiotics. This is followed by targeted antibiotic therapy for 6 weeks, based on samples sent to the laboratory for culture. Finally, the second stage involves placing a new prosthesis.

Revision Shoulder Arthroplasty is a very demanding surgery and requires an Orthopedic Surgeon with extensive experience in similar cases. It also requires appropriate preparation and study, with careful preoperative planning, imaging, laboratory testing, and many times the participation of a wider therapeutic team, which may, in addition to the shoulder surgeon, include a musculoskeletal and interventional radiologist, an infectious disease specialist, a pathologist, and other specialties, depending on the needs of the patient (MDT, or multidisciplinary team).

Dr Panagopoulos has extensive experience in revision shoulder arthroplasty, having served as an active member in a revision surgical center abroad. This operation must only be performed by a specialized Orthopedic Surgeon with relevant experience, with an organized surgical and medical team, in a specialized hospital with the necessary logistical infrastructure and workforce.

How to choose the best orthopaedic surgeon | 9 tips for meaningful search results

The correct treatment of orthopedic problems is important both for our quality of life and for a quick return to everyday life, work and sports activities. Many times, a simple search on the internet is not enough to find the right or best orthopaedic surgeon, especially if we are dealing with the right choice of surgeon. Much of the information available out there is misleading when looking for "best orthopaedic surgeon". We often come across someone who calls himself a "top orthopedic surgeon" in his kind on his personal website, or who calls himself the first to bring a "revolutionary" technique to Greece. Therefore, special attention is needed to avoid mishaps. 

Check the surgeon's CV

First of all, make sure that the doctor you have chosen is a member of a medical association (eg, the Medical Association of Athens) and that the practice operates legally. Beyond that, the résumé should contain detailed information about the doctor's career thus far, such as his undergraduate studies, possible graduate degrees, and what he did as a specialty or specialization.The résumé should be detailed and without long gaps between doctor placements.

Studies & Specialty

Undergraduate studies and master's degrees or a doctorate (PhD) are important for a doctor. Equally important is their writing work, as well as participation in lifelong learning. Does the doctor in this case have a writing activity to show? Have they published articles with his studies in international journals (peer-reviewed journals), which are available on Pubmed? Of course, the abundance of publications is not necessarily indicative of the doctor's abilities. It is not enough to say they are the "best orthopedist". But it is an indication that the particular scientist has done research and has dealt thoroughly with his subject. 

Καλύτερος Ορθοπαιδικός 2
Καλύτερος Ορθοπαιδικός 3

Equally necessary in our time, is the specialization of the Orthopedic Surgeon. It stands to reason that surgeons who perform a high volume of specific procedures have more experience, better outcomes, and a lower complication rate than surgeons who perform fewer procedures, or who deal with multiple areas. Someone who performs 200-300 shoulder arthroscopies per year, obviously has more shoulder arthroscopies experience than someone who does 2 shoulder arthroscopies and 198 hip replacements per year. No one nowadays can claim to do everything equally well for some mysterious reason.

Experience overseas

Abroad, the Orthopedic Surgeon, after completing the specialization, specializes for at least 1-2 years in a center of reference in the subject of his interest (Fellowship). This detail is extremely important for the correct choice of surgeon. In Greece, unfortunately, the concept of further specialization after training is not widespread. In the majority of Western countries, such as North America (United States and Canada) or England, specialization is a given. In other words, the Surgeon specializes, e.g. in Shoulder & Elbow, Hand, Hip & Knee Surgery, Spine Surgery, etc. Then, they continue their career dedicated to their subject (e.g., as a Spine Surgeon). 

Make sure your doctor is a “Fellowship-trained Orthopedic Surgeon” in the subject related to your problem, in one of the major centers abroad, since there is no corresponding center in Greece that offers this training.

Of course, many times, what is included in a resume may not be so clear, or may be misleading. It is, unfortunately, a common practice to state that the doctor has expertise abroad without further details or clarifications.There are not a few who make a short visit or attend a seminar abroad, and then write on their CV "Educated in the United States" or "Studied under Professor X or Y". The actual further training / specialization lasts at least 1 – 2 years in a salaried position.It requires certification in the country of practice with exams, a license to practice and registration with the local Medical Association.

It is important to know exactly what the doctor did abroad (were they a simple observer or did they make decisions and perform operations themselves). Attending seminars or conferences does not make one an expert surgeon in one subject. Also, experience abroad in Observership (observer=shadowing only), Traveling Fellowship (traveling fellow = visitor),  or Postdoctoral research (postdoc = research) does not constitute surgical specialization. The Traveling Fellowship, in particular, is a few-day visit to the Practice of colleagues abroad, in order to get ideas from their own modus operandi. It usually involves older colleagues who wish to broaden their horizons. Unfortunately, it has been observed that younger colleagues participate in such programs and present them as expertise. 

Finally, in cases where continuing education in America (USA) is mentioned, ask if the doctor is ECFMG-certified (Educational Commission for Foreign Medical Graduates), i.e. has passed the USMLE (United States Medical Licensing Examination), which are mandatory in order to to obtain a professional license and to "touch" a patient. With few exceptions, a doctor without a USMLE is not allowed to practice and operate in America. 

Ask more about the surgeon's experience

Make sure your doctor has the required experience to treat your problem. You can ask directly how many similar cases he has dealt with in the past, or ask to be contacted by patients who are willing to talk about their experience with that particular doctor.

Seek recommendations from multiple sources

You can look for recommendations from many sources. Ask as many friends and family as you can. You will see that usually 1-2 names will come up more than once, giving more credibility to your research. Some good sources for recommendations are the following:

  • Your GP, or General Practicioner
  • Close friends
  • Family members
  • Social media (be careful, though)
  • The doctor's website, especially if it contains testimonials
  • Reviews from trusted sources, like Google
  • A physiotherapist, nursing staff, or other healthcare workers. OR staff usually knows well who does what
  • Ask your health insurance agent, as they are likely to have experience from other patients treated by the doctor in question

Discuss with the doctor

  • Talk to your doctor thoroughly about your condition and your options. A good doctor will analyze all your possibilities and options.
  • Ask the doctor about their experience, the number of surgeries they have performed, and their complication rate. There is no such thing as a zero complication rate!
  • For all operations, no matter how simple, possible complications are described in the literature. Ask the doctor about the risks and benefits of the procedure and about the possible complications in general. 
  • Choosing the right surgeon is impossible if this person does not inspire us with confidence. Get to know them better.

Ask about the hospital & surgical team

  • Prefer an organized and large hospital, where all medical specialties will be readily available.
  • Choose a hospital with modern technological equipment and organized surgeries. Operations in organized hospital units have lower rates of post-operative complications, eg infections.
  • Prefer organized medical teams, with experienced partners and specialized nursing staff.

Enquire about the costs of the procedure

  • Ask if the surgery is covered by your private insurance and if the hospital is contracted.
  • Ask if financial packages are provided for your insurance company, e.g. EOPYY, OGA, etc.

Ask for a second opinion 

If you are not completely satisfied or confident with the choice of surgeon you have made, it is not a bad idea to seek other opinions. The best Orthopedic Surgeon is the one who not only combines the above characteristics, but also the one who will spend the necessary time in order for you to fully understand your problem, and for all your questions to be resolved.

Shoulder Arthroscopy: Exploring the Benefits of a Minimally Invasive Procedure

Shoulder pain and injuries can significantly impact one's quality of life, making simple tasks challenging and limiting mobility. Fortunately, advancements in orthopaedic surgery have introduced shoulder arthroscopy as a minimally invasive procedure with a range of benefits. In this article, we will explore the advantages of shoulder arthroscopy, highlighting its ability to provide faster recovery, reduced pain, improved accuracy, and a quicker return to daily activities.

What's shoulder arthroscopy?

Shoulder arthroscopy is a minimally invasive surgical procedure that uses a tiny camera called an arthroscope to examine or repair the tissues inside or around your shoulder.

During shoulder arthroscopy, the surgeon will make small incisions in the front and side of your shoulder to insert a camera & tiny instruments in order to address all pathology found.

The arthroscope is essentially a slim telescope (4.5mm or 2.9mm) with a high-definition camera, surrounded by a fiber-optic tube that functions as a light source. In order to see inside the joint and to undertake any procedures, the joint needs to be ‘opened’ up. This is done by distending the joint with normal saline fluid. A specialized pump is used to control the pressure and rate of fluid going into the joint, to optimize visualization. The surgeon will make small incisions in the front and side of your shoulder to insert tiny instruments in order to address all pathology found. Multiple arthroscopic instruments may be used during the procedure.

What are the benefits of shoulder arthroscopy?

Minimally Invasive Approach for Reduced Pain and Discomfort

Shoulder arthroscopy utilizes small incisions and specialized instruments to access and treat various shoulder conditions. This minimally invasive approach significantly reduces postoperative pain and discomfort compared to traditional open surgeries. Patients often experience less tissue damage, minimal scarring, and reduced reliance on pain medications during the recovery period.

Improved Accuracy and Precision for Effective Treatment

Shoulder arthroscopy allows orthopaedic surgeons to visualize the internal structures of the shoulder joint with the help of a tiny camera called an arthroscope. This detailed view enables precise diagnosis and targeted treatment of various shoulder conditions, including rotator cuff tears, labral tears, shoulder instability, and shoulder impingement. The improved accuracy of the procedure enhances the effectiveness of treatment and increases the likelihood of successful outcomes.

Quicker Recovery and Rehabilitation Process

With shoulder arthroscopy, patients often experience a faster recovery compared to traditional open surgeries. The smaller incisions result in less trauma to surrounding tissues, leading to reduced inflammation and a quicker healing process. Additionally, the minimally invasive approach allows for an earlier initiation of physical therapy, aiding in the restoration of shoulder strength, flexibility, and range of motion. Patients can resume their daily activities and return to work or sports sooner than with traditional surgical methods.

Customized Treatment Options for Individual Needs

Shoulder arthroscopy offers a wide range of treatment options tailored to the specific needs of each patient. Orthopaedic surgeons can address various shoulder conditions, such as removing loose fragments, repairing torn tendons or ligaments, and smoothing rough cartilage surfaces. The ability to customize treatment based on individual requirements contributes to better outcomes and patient satisfaction.

Lower Risk of Complications and Infections

Minimally invasive shoulder arthroscopy carries a lower risk of complications and infections compared to open surgeries. The smaller incisions result in fewer wound-related issues and decrease the risk of postoperative infections. The reduced risk of complications ensures a smoother recovery process and improved patient safety.

Conclusion

Shoulder arthroscopy stands as a remarkable orthopaedic procedure that offers numerous benefits to patients with shoulder conditions. Through its minimally invasive approach, this technique provides reduced pain, improved accuracy, faster recovery, and a quicker return to daily activities. With customized treatment options and a lower risk of complications, shoulder arthroscopy has become a preferred choice for many individuals seeking effective shoulder pain relief and enhanced quality of life.

The advantages of arthroscopy are great, but that doesn't mean arthroscopy is for everyone and everything. Certain shoulder pathologies often require open surgery, such as advanced arthritis, rotator cuff arthropathy, or most fractures. Also, it is important that arthroscopy is performed by experienced hands , as there is a significant learning curve.

So it is extremely important that the surgeon we choose is able to make the right decision on the one hand, and on the other hand to be able to perform the surgery safely.

Dr Panagopoulos has extensive surgical experience in shoulder arthroscopy, & will direct you during your visit to the doctor's office, as to the appropriate treatment options for your condition.
