One of the most common complications of total shoulder arthroplasty (TSA) is glenoid component loosening due to implant-cement fixation failure. High cement stresses resulting in fracture are believed to result from malpositioning the glenoid implant [1]. Ideal glenoid preparation and placement, however, are not always achievable due to significant anatomical alterations caused by arthritis resulting in posterior glenoid erosion and increased glenoid retroversion. To our knowledge, prior research has not compared the effects of insufficient reaming depth and incomplete version correction on the likelihood of cement mantle failure. The purpose of this study was to investigate how the degree of correction of the glenoid vault affects cement mantle stress and potential cement failure.
