Thumb Arthrokinematics Cmc Explained Easily Convex Concave Rules

Arthrex Thumb Cmc Arthroscopy In this video i talk about the arthrokinematics of the thumb it being a saddle joint and it can move in flexion extension, abduction and adduction depending on its direction and joint concave. While the joint surface of the trapezium is convexe in the dorso palmar direction, it is concave in the ulno radial direction. the corresponding joint surface of the 1st metacarpal bone presents with the opposite curvature.

Cmc Joint Cheap Online Ids Deutschland De Study with quizlet and memorize flashcards containing terms like rule, abduction, adduction and more. Understanding those key features of the thumb cmc joint is essential to adequately treat its pathology, such as fracture dislocation, ligamentous injury, and degenerative osteoarthritis. The convex concave rule is the basis for determining the direction of the mobilizing force when joint mobilization gliding techniques are used to increase a certain joint motion. the direction in which sliding occurs depends on whether the moving surface is concave or convex. The beak of the thumb metacarpal, the beak recess adjacent to the volar beak ligament, and the dorsal ligament complex are key biomechanical components of thumb cmc joint stability. these key components prevent joint subluxation during pinch and grasp movements. the thumb cmc joint is complex.

Empirical data to date are insufficient to describe the role of altered biomechanics in thumb carpometacarpal (cmc) arthritis. this is a pilot study to evaluate motion analysis of the upper extremity while performing functional tasks. Study with quizlet and memorize flashcards containing terms like 1st cmc joint proximal surface, 1st cmc joint distal surface, 1st cmc joint type and more. The convex concave rules of arthrokinematics: flawed or perhaps just misinterpreted? donald a. neumann, pt, phd, fapta.
