BACKGROUND: @entity2530 ( @entity2530 ) of the humeral head is a known @entity455 . Prosthetic replacement may be the last option to treat the associated @entity158 . Depending on the condition of the glenoid, hemiarthroplasty (HA) or @entity348 ( @entity348 ) can be considered. To date, the peer reviewed literature offers limited direction on the better treatment for this population. METHODS: Between 1973 and 2010, 93 arthroplasties were performed for post-traumatic @entity2530 of the humeral head after conservative treatments failed. Of these, 37 HAs and 46 TSAs were monitored for a minimum of 2  years (mean, 8.9  years) or until reoperation. RESULTS: The HA and @entity348 groups showed improvements in @entity158 (P  <  .001), elevation (P  <  .01), and external rotation (P  <  .01). The @entity348 group had less @entity158 at follow-up than the HA group (2.1 vs 3.0, P  =  .001). @entity348 led to better satisfaction (70% vs 56%) and more excellent/satisfactory Neer ratings (57% vs 41%) compared with HA. Nine HA @entity1 and 5 @entity348 @entity1 underwent reoperation. The most common causes for reoperation were @entity158 glenoid @entity4040 (n = 8) in HA and rotator cuff failure (n = 4) in @entity348 . The estimated 15-year survivorship was 79.5% for HA and 83% for @entity348 . DISCUSSION: In @entity1 with post-traumatic @entity2530 of the humeral head, shoulder arthroplasty provides improvements in range of motion. However, @entity348 provides superior @entity158 relief, with better @entity1 -reported satisfaction. @entity348 should be strongly considered in @entity1 with post-traumatic @entity2530 of the humeral head with damage to the glenoid cartilage.
