Orthopaedics · Fractures: Neer classification

Sample item

In the Neer classification of proximal humerus fractures, a segment is considered displaced when it is displaced by more than which of the following?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. 1 cm or angulated more than 45 degrees

Neer divides the proximal humerus into four segments: the head, greater tuberosity, lesser tuberosity and shaft. A segment counts as a separate displaced part only if displaced more than 1 cm or angulated more than 45 degrees.

Option by option

  • A. 2 cm or angulated more than 90 degrees

    These thresholds are too large.

  • B. 3 cm or angulated more than 30 degrees

    These values do not match the Neer criteria.

  • C. 1 cm or angulated more than 45 degrees (correct)

    Correct. Displacement over 1 cm or angulation over 45 degrees defines a part.

  • D. 5 mm or angulated more than 10 degrees

    These thresholds are too small and would classify most fractures as multi-part.
