  LATERAL AND MEDIAL ENDS:-

 1. Lateral end :-

• Known as Acromial end.
• Flattened from above downwards. 
• Bears facet for articulation with the acromion process of scapula to form ACROMIOCLAVICULAR JOINT. 

2. Medial end :- 

• Known as sternal end. 
• Quadrangular and articulates with the clavicular notch of the manubrim sterni to form STERNOCLAVICULAR JOINT. 
• Articular surface extends to the inferior aspect for articulation with the FIRST COASTAL CARTILAGE. 

SIDE DETERMINATION:-

• lateral end flat and medial end quadrangular and large. 
• curved shaft:- 
1. Convex forwards medial 2/3rd .
2. Concave forwards lateral 1/3 rd.
• Inferior surface is grooved longitudinally in middle 1/3 rd.
