Geometry of Condyloid Joint Between Metacarpal And Phalanx Bones Posted: 11-17-07 05:28am
How does the geometry of this joint work?
I understand it has ovoid and elliptical
surfaces, but not how they move wrt each
other.
Is there only sliding, only rolling, or
both?
Are the extension/flexion movements
equivalent to simply rotating about the
center of curvature of the "ball" on the
metacarpal? How about the sideways
movement?
Is this joint funtamentally different from
an arthrodial, hinge or ball-and-socket
joint?
Cheers.

Is this for a homework assignment?
This type of joint allows movement but no
rotation. It is a "gliding joint".
Yes, it is fundamentally different ...
Hi, thanks for the reply, but I've seen a
few descriptions of it and they're all as
vague as that link. This is the joint on
the knuckles so it does rotate. I'm
looking for a more quantitative
description of the possible movements it
can make for a typical person.
