An increase in the mean of Group A of 1.02 mm and Group B of 2.58 mm was observed.
The main idea behind this study is to provide guidelines about the reverse shoulder autopsy and surgical learning curve. The reports of sixty-two shoulder autopsies done by a surgeon were thoroughly reviewed.
Linear regression slope was calculated by plating surgical time against patient case order based on the surgical data. The slope calculated was found to be a negative slope. The number of cases was considered a proficiency point.
Further, the series was divided into two groups for verifying the proficiency point. The patients who had surgery before the proficiency point were included in Group A.
And patients who had surgery after proficiency point were included in Group B. In Group B 66 % of patients has four glenoid baseplate screws whereas in group A only 33 % had four glenoid baseplate screws.
Therefore, an increase in the mean of Group A of 1.02 mm and Group B of 2.58 mm was observed.
The complete question is -
Evaluation of the learning curve for reverse shoulder arthroplasty.
