    Summary
    This summary is machine-generated.

    A new classification system for subtle carpal instability, excluding major injuries, is proposed. This framework categorizes instability into lateral, central, medial, and proximal types based on three carpal columns.

    Area of Science:

    • Orthopedics
    • Anatomy
    • Biomechanics

    Background:

    • Carpal instability often presents subtly, complicating diagnosis.
    • Existing classifications may not fully capture nuanced patterns of carpal dissociation.
    • Understanding carpal column dynamics is crucial for diagnosing instability.

    Purpose of the Study:

    • To propose a novel classification system for subtle carpal instability.
    • To delineate patterns of instability based on carpal column interactions.
    • To provide a framework for understanding and diagnosing various carpal instabilities.

    Main Methods:

    • Modification of Navarro's concept of the carpus.
    • Definition of three vertical longitudinal carpal columns: lateral (scaphoid), central (lunate and distal carpal row), and medial (triquetrum).

  • Categorization of instability based on dissociations between these columns and with the distal radioulnar joint.

    • Main Results:

    • Identified four main types of carpal instability: lateral, central, medial, and proximal.
    • Subdivided lateral carpal instabilities into scaphoid-trapezium-trapezoid subluxation, scaphoid-capitate diastasis, and scaphoid-lunate dissociation.
    • Described central instability, medial (lunate-triquetrum) instability associated with volar-flexed intercalated segment instability, and proximal (radiocarpal) instability.

    Conclusions:

    • The proposed three-column classification provides a structured approach to subtle carpal instability.
    • This system aids in differentiating various patterns of carpal dissociation.
    • Understanding these patterns is essential for accurate diagnosis and treatment of carpal instability.
