The Hand

Question 0

Finger MCPs

Answer 0

2 degrees of freedom; permits movement of flexion/extension and abduction/adduction
Capsular pattern: equal restrictions of flexion/extension

Question 1

The hand joints

Answer 1

Fingers: metacarpophalangeal joints (MCP)
Fingers: proximal and distal interphalangeal joints (PIP and DIP)
Thumb: carpometacarpal joint (CMC)
Thumb: metacarpophalangeal joint (MCP)
Thumb: interphalangeal joint (IP)

Question 2

Finger PIP and DIP

Answer 2

Synovial hinge joints with one degree of freedom: flexion/extension
Capsular pattern: equal resistance of flexion/extension

Question 3

Thumb CMC joint

Answer 3

Saddle joint with 2 degrees of freedom: flexion/extension and abduction/adduction
Capsular pattern: limitation of abduction and extension

Question 4

Thumb MCP

Answer 4

Condyloid joint with 2 degrees of freedom: flexion/extension and minimal abduction/adduction
Capsular pattern: restriction of motions in all directions but flexion more limited than extension

Question 5

Thumb IP

Answer 5

Synovial hinge joint with 1 degree of freedom: flexion/extension
Capsular pattern: equal restrictions of flexion/extension
