Neer Classification (Proximal Humerus Fracture)

Classifies proximal humerus fractures by number of displaced parts. Guides conservative vs surgical management.

Score interpretation

Neer 1-part (minimal displacement)

→ Conservative: sling for 3-6 weeks; physiotherapy; good outcome expected. Fracture-dislocation (associated glenohumeral dislocation): urgent orthopaedic review.

Neer 2-part fracture

→ ORIF or conservative depending on type; surgical neck fractures may need fixation. Fracture-dislocation (associated glenohumeral dislocation): urgent orthopaedic review.

Neer 3-4 part fracture

→ ORIF or hemiarthroplasty; high AVN risk with 4-part; reverse shoulder arthroplasty in elderly. Fracture-dislocation (associated glenohumeral dislocation): urgent orthopaedic review.
