Table 3 We correlated the grade of infraglenoidal scapular notching according to Nerot et al. after implantation of an inverted total shoulder prosthesis Delta with stability scores and clinical scores using a spearman correlation

  1. These correlations were calculated using mean values of the mid-term (MT-Fup) and long-term follow-up (LT-Fup) groups. Note that we found a significant correlation of notching with clinical scores after dividing in a mid-term (24-60 months) and long-term follow-up (over 60 months).
