Total Shoulder Replacement

- Discussion:
    - see shoulder replacement discussion (total shoulder vs hemiarthroplasty vs reverse arthroplasty)
    - the indications for total shoulder arthroplasty (versus hemiarthroplasty) are controversial;
           - there is some controversy regarding pain relief and component survivorship;
           - Gartsman GM, et al (2000), the authors compared hemiarthroplasty (24 shoulders) to TSR (27 shoulders);
                  - mean followup was 35 years;
                  - they noted significantly better pain relief and better internal rotation with total shoulder replacement;
                  - there was a trend for better patient satisfaction, function, and strength in TSR group; 
           - non concentric glenoid
                  - non-concentric glenoid (ie posterior glenoid erosion) is a clear indication for glenoid resurfacing, since a congruent joint is  necessary
                             for optimal function;

- Radiographs:
    - note the relation of the tuberosity and the humeral head (optimal to reproduce the vertical offset)
    - axillary view

- Surgical Technique:
    - surgical exposure
    - humeral preparation
    - glenoid component
    - trial reduction 
    - management of subscapularis - repair
