Scapular notching in reverse shoulder arthroplasty
Diagnosis almost certain
Updates to Study Attributes
Findings
was changed:
There is erosion of the lower edge of the scapular glenoid due to impingement of the humeral insert humeral versus the scapula.
Updates to Case Attributes
Body
was changed:
With this type of prosthesis the center of rotation is placed in theshifted medial of about 2 cm in order to increase the lever arm of the deltoid muscle.
This solution increases the abilityrisk of the glenoid erosion and instability of glenosphere.
To overcome this risk are madethe prosthesis glenosphereis enlarged, lowered and tilted medially (glenosphere eccentric) while on thethe humeral insert humeral you createdcreates a medial recess.
