Type of joint: Hinge joint (engagingly) with one degree of freedom allowing
for flexion and extension
Capsular pattern: Flexion > extension
Type of joint:Β This joint is classified as a condyloid joint with two degrees
of freedom (flexion and extension, radial and ulnar deviation). The articulation of the proximal and distal rows of metacarpals are of the same classification and also allow for flexion and extension.
Capsular pattern:Β Equal restriction of all motions
