Glenoid Fracture- Teaching Points
Questions between Reporting doctor and Professor. Submitted by Dr MGK Murthy
What is this?
Answer- it is a fracture
Where?
Involves infraglenoid tubercle and axillary(lateral border)of scapula
What is the importance?
Triceps get origin from infraglenoid tubercle and teres muscles get attachment from the border
How is the joint ?
Gleno-humeral joint is maintained
What causes it?
Scapular neck fractures most frequently result from an anterior or posterior force applied to the shoulder. Glenoid rim fractures most often result from force transmitted along the humerus after a fall onto a flexed elbow. Stellate glenoid fractures usually follow a direct blow to the lateral shoulder
Types ?
Classification of glenoid cavity fractures: IA - Anterior rim fracture; IB - Posterior rim fracture; II - Fracture line through the glenoid fossa exiting at the lateral border of the scapula; III - Fracture line through the glenoid fossa exiting at the superior border of the scapula; IV - Fracture line through the glenoid fossa exiting at the medial border of the scapula; VA - Combination of types II and IV; VB - Combination of types III and IV; VC - Combination of types II, III, and IV; VI - Comminuted fracture
Which is this ?
It is possible type II
What next
