BACKGROUND: The prevalence of @entity28 in the United States continues to increase. Attention has recently turned to an emerging population of extremely overweight @entity1 , termed superobese and defined as those with body mass index (BMI) >= 50  kg/m(2). The goal of this study was to use a national database to evaluate postoperative complication rates after @entity348 ( @entity348 ) in superobese @entity1 and to compare @entity1 of different BMI classes. METHODS: @entity1 who underwent @entity348 or reverse @entity348 were identified in the PearlDiver database by International Classification of Diseases, Ninth Revision (ICD-9) codes. These @entity1 were then divided into nonobese, @entity28 , and superobese cohorts by ICD-9 codes. @entity260 were assessed and compared between cohorts. RESULTS: From 2005 to 2012, 144,239 unique @entity1 who underwent @entity348 or reverse @entity348 were identified, including 105,661 nonobese @entity1 , 23,864 @entity28 @entity1 , 13,759 morbidly @entity28 @entity1 , and 955 superobese @entity1 . Superobese @entity1 had a significantly higher rate of @entity281 , dislocation, component loosening, revision shoulder arthroplasty, @entity1211 , and medical complications after shoulder arthroplasty compared with nonobese controls. CONCLUSIONS: Obesity is associated with significantly increased rates of numerous complications after @entity348 , including @entity281 , dislocation, component loosening, revision surgery, @entity1211 , and medical complications, compared with nonobese controls. Superobesity (BMI  > 50  kg/m(2)) is associated with significantly increased rates of several complications compared with even @entity28 and morbidly @entity28 @entity1 , including @entity1211 , and medical complications.
