Hemi to Total Hemi to Total Follow up 5.5 years Unsatisfactory Outcome (47%) Reoperations (33.3%) Follow up ~5 years Complications (45%) Reoperations (21%) How do we decide? Value Based Decision Making Purpose: Clin Orthop Relat Res. 2016 Nov;474(11):2482 2492. Functional Outcome Cost Survival To create decision model that could evaluate cost and effectiveness of hemiarthroplasty and total shoulder arthroplasty in a cohort of young patients (US population 30 50 yrs at risk Monte Carlo simulation).

Threshold Analysis Implications How could Hemis be made to equal totals? total reimbursement of hemi to 16,600k/case (from 17.8k) 10 years survival rate of hemi to 90.7% (from 82%) Treatment of glenohumeral arthritis in patients aged 30 to 50 in the United States with total shoulder arthroplasty, instead of hemiarthroplasty, would results in: 1. Greater cost savings 2. Avoid a substantial number of revision surgeries 3. Greater years with a satisfactory outcome Disclaimer: per case patient selection for treatment remains important Personal Approach Personal Approach Accept that all patients will need revision Minimize the number aim for 1 2 Choose least invasive option with any hope of success Preserve joint if possible When sacrificing the joint, preserve as much bone as possible especially glenoid Include patient in the process shared decision making Every patient gets initial nonoperative management Primarily injections and activity modification Arthroscopic debridement Concentric joint, mild to moderate deformity, mild to moderate stiffness Arthroscopic capsular release Concentric joint, no to mild deformity, moderate to severe stiffness Arthroscopic interposition Rarely used extremely young, concentric glenoid, bad glenoid, minimal deformity, mild to moderate stiffness Open debridement/capsulectomy Extremely young/active, concentric joint, no longer use interposition, motivated patient Hemiarthroplasty Most lifters, ream if biconcave, motivated patient, no longer use resurfacing, stemless good option Total shoulder Concentric joint in lay glenoid Biconcave augmented component Conclusions There are no right answers. There are only individualized decisions Thank You No treatment is life-long No treatment is curative Consider the revision surgery Tremendous opportunity for innovation 11
