Neer classification is used to categorize fractures of which bone?

• A. Proximal femur
• B. Proximal humerus
• C. Distal radius
• D. Scapula

Answer: (B)

Neer classification describes fractures of the proximal humerus. It categorizes injuries by how many fragments are displaced, using displacement thresholds (more than about 1 cm or more than 45 degrees of angulation) to count a fragment as a separate part. The typical fragments involved are the humeral head, the surgical neck, and the greater and lesser tuberosities. A two-part fracture means one fragment is displaced with respect to the rest, three-part involves two displaced fragments, and four-part involves three displaced fragments. This system helps guide treatment decisions, since more parts displaced generally predict a more complex injury and a higher likelihood of needing surgical management.
