Dr. Allman initially classified clavicle fractures as:
Group 1: Middle 1/3 (80%)
Group 2: Distal 1/3 (15%)

Dr. Neer further categorized distal 1/3 fractures (group 2) into 5 types:
Type 1: Lateral to CC ligaments
Type 2a: Medial to CC ligaments (CC intact)
Type 2b:
-Medial to trapezoid (conoid torn)
-Medial to trapezoid (both CC torn)
Type 3: Intraarticular involving AC joint
Type 4: Physeal injury (pediatric)
Type 5: Comminuted
