Understanding wrist function requires examining carpal bone interactions and stability theories. This paper details normal and pathologic wrist mechanics, instability types, and potential treatments for improved hand positioning.

Area of Science:

  • Orthopedics
  • Biomechanics
  • Anatomy

Background:

  • The wrist's primary role is to position the hand for optimal task performance.
  • Achieving optimal hand positioning necessitates a wide range of motion coupled with joint stability.
  • Traditional row and columnar theories attempt to explain the mechanics of wrist motion and stability.

Purpose of the Study:

  • To elucidate the functional anatomy of the wrist.
  • To discuss the normal and pathologic interactions of carpal bones.
  • To describe various forms of wrist instability and potential treatments.

Main Methods:

  • Review of existing literature on wrist biomechanics and anatomy.
  • Analysis of carpal bone interactions based on established theories (row and columnar).
