Educational video describing fracture classifications of the scapula.
Acromial fractures
Kuhn classification
Type Ia
•minimal displacement (avulsion fracture) .
•no surgical treatment
Type Ib
•minimal displacement (complete fracture) .
•no surgical treatment
Type II
•displaced fracture without reduction in the subacromial space.
•Non-operative treatment
Type IIIa
•reduction of the subacromial space by inferior displacement of the acromion.
•Fixation with screws or plate.
Type IIIb
•reduction of the subacromial space by superiorly displaced glenoid fracture.
•Reduction and fixation with plate
Coracoid fractures
Ogawa classification
Type I
•Fracture proximal to the coracoclavicular ligaments usually associated with acromioclavicular separation, clavicular fracture, superior scapular fracture or glenoid fracture.
•Reduction and fixation with screws.
Type II
•Fracture distal to the coracoclavicular ligaments.
•No surgical treatment.
Intra-articular glenoid fractures
Ideberg classification
Type Ia
•Fracture of the glenoid rim (anterior)
•No surgical treatment
Type Ib
•Fracture of the glenoid rim (posterior)
•No surgical treatment
Type IIa
•Transverse fracture through the glenoid fossa with an inferior triangular fragment displaced with the sbuluxated humeral head.
•Fixation plate or screws
Type IIb
•Oblique fracture through the glenoid fossa with an inferior triangular fragment displaced with the subluxated humeral head.
•Reduction and fixation with plate or screws.
Type III
•Oblique fracture through the glenoid exiting at the mid-superior border of the scapular, often associated with acromioclvicular fracture or acromioclavicular dislocation.
•Reduction and fixation with screws
Type IV
•Horizontal fracture, exiting through the medial border of the scapular body.
•Reduction and fixation with screws.
Type V
•A combination of type IV with a fracture separating the inferior half of the glenoid.
•Reduction and fixation with screws
Extra-articular glenoid fractures
Type I
Fracture of the glenoid neck without associated fracture or AC joint separation.
Reduction and fixation with plate
Type II
•Fracture of the glenoid neck with associated clavicle fracture and AC separation (secondary suspensory ligaments involved).
•Reduction and fixation with clavicle plating only, scapular plating only, or scapular & clavicular plating.
