“…As previously stated, the recent literature has found bone loss to occur in a posteroinferior direction towards the 8 o'clock position [14][15][16][17]. This may result in significant bone removal in order to achieve full backside seating [27,28]. Furthermore, when using either augmented or standard components in patients with asymmetric erosion, significant differences occur in the bone density and quality of underlying bone [27,28], which may further complicate the stability and fixation of glenoid components.…”

“…Recent clinical [19•, 20, 21], experimental [22][23][24][25][26], and computational [27][28][29][30][31] studies addressing asymmetric posterior glenoid erosion have focused on eccentric reaming and/or retroversion correction. It has been suggested that retroversion correction greater than 15°cannot be achieved with eccentric reaming alone [26,32].…”

The number of shoulder arthroplasty procedures has increased dramatically in recent years, with the primary indication being osteoarthritis (OA). Thus, morphology and subchondral bone changes associated with OA may be important factors to consider when choosing a replacement component. For surgical treatment, many implant options exist and survivability is often dependent on patient age, activity level, and progression of OA. In the placement of these replacement components, patient-specific guides now exist to improve component positioning, with the goal to improve long-term survivability by ensuring that intra-operative placement meets component design.

“…Surgical techniques vary depending on the morphology but all technique has its disadvantage. Anatomical glenoid correction by reaming may be performed but as a result, the joint will be medialized, thus the lever arm of the surrounding muscle will decrease [111]. Also due to excessive reaming, glenoid bone stock will be lost and while inserting the component, the pegs may perforate the cortex which will result as loosening, fracture and in the long-term the revision surgery will be complicated.…”

Background: Rheumatoid arthritis (RA) is an inflammatory disease resulting in pain and decreased functional outcome. Even though most of large joints are widely discussed in literature, shoulder's surgical treatment options, indications and superiorities to each other were not compared entirely. Materials and methods: Treatment options, such as synovectomy and bursectomy, resection interposition arthroplasty (RIAP), hemiarthroplasty, humeral resurfacing arthroplasty, anatomical total shoulder arthroplasty (TSA) and reverse shoulder arthroplasty (RSA) are examined and compared according to timing, advantages and disadvantages. Results: Age is the primary criteria for decision making. Young-aged patients demand high functionality, alas need for revision in the future must be planned. First step is preservation of bone stock as much as possible. For young patient, disabling pain can be candidate for synovectomy and bursectomy or RIAP and also for hemiarthroplasty. As age progresses, priorities change towards rotator cuff status and glenoid bone stock. Conclusions: Age, functional demand, rotator cuff status, adequacy of glenoid bone stock and future planning for possible complications are defined as major criteria for optimal treatment. RA patients will require systemic evaluations with help of rheumatologists. Patient, rheumatologist and orthopaedist should discuss the possible surgical intervention together to achieve high quality of life.

“…31 Finite element analysis and computer modeling also have shown that, compared with eccentric anterior reaming, both the wedge and the step component designs preserve more bone and lead to less muscle shortening of the rotator cuff. [32][33][34] It has been suggested that the wedge design may be more bone-sparing and may lead to less medialization than the step design.…”

Areas of current controversy concerning shoulder arthroplasty include management of glenoid bone loss, the role of patientspecific instrumentation, differing design features of reverse shoulder arthroplasty, and options for humeral fixation in primary and revision procedures. At the 2015 meeting of the American Academy of Orthopaedic Surgeons, shoulder arthroplasty specialists presented a symposium on these controversial topics. In each area, surgeons presented their case for a given position on these issues. This article is a summary of those proceedings.
