This 50 years old case has a Concomitant partial supraspinatus tear which is important for functional outcome in proximal humerus fractures.
You should correlate radiographic characteristics with rotator cuff tendon injury on magnetic resonance imaging after fractures of the proximal humerus.
MRI examinations confirm rotator cuff tears ( partial or full thicknesses) diagnosed at the time of injury, and also additional tears can be diagnosed (partial or full thicknesses) later at the time of follow up .
Functional loss at one year may occur due to the tears at the time of injury, varus malunion of the head and displacement of tubercles.
