The greater tuberosity is critical for rotator cuff function and therefore shoulder stability.
Surgery may be required for a displaced greater tuberosity fracture to optimize shoulder rehabilitation.
The greater tuberosity serves to improve deltoid muscle function (deltoid wrapping) and as the attachment for the posterior rotator cuff.
Surgery may be required for a displaced greater tuberosity fracture to optimize shoulder rehabilitation.
Fracture of the greater tuberosity can occur by distraction or avulsion:
Plain x-rays, particularly the scapular Y view, can demonstrate the fracture, especially in displaced cases. CT is recommended in suspected fractures and to evaluate displacement.
