Chapter 5: Bones, Joints, and Ligaments of the Wrist and Hand

The 1st carpometacarpal (CMC) joint is a ___________________ joint.

Saddle - Unique Movements - Flexion (frontal plane) - Extension (frontal plane) - Abduction (sagittal plane) - Adduction (sagittal plane) - Opposition (oblique) - Circumduction

Joints of the hand

1. Carpometacarpal joints (CMC) 2. Metacarpophalangeal joints (MCP) 3. Interphalangeal joints - Distal interphalangeal joints (DIP) - Proximal interphalangeal joints (PIP)

Interphalangeal (PIP and DIP) articulations are __________________________, and include ________________________ movements.

1. Hinge 2. Flexion and extension

Carpometacarpal (CMC) articulations are ______________________.

Gliding

Intercarpal articulations are _______________________.

Gliding

Metacarpophalangeal (MCP) articulations are ________________________, and include ___________________________ movements.

1. Conyloid 2. Flexion, Extension, Abduction, Adduction, Circumduction

The movements of the wrist are ________________________.

1. Flexion 2. Extension 3. Ulnar Deviation (Adduction) 4. Radial Deviation (Abduction) 5. Circumduction

Bones of the hand

1. Metacarpals (5) 2. Phalanges - Distal - Middle - Proximal

Joints of the wrist

1. Radiocarpal joint (wrist joint) - Between the forearm (radius) and the wrist (carpals) 2. Ulnarcarpal joint - Between the forearm (ulna) and the wrist (carpals) 3. Intercarpal joints - Between all carpal joints

The ___________________ is the most commonly fractured carpal. The _________________________ is the carpal that is most commonly dislocated during FOOSH.

1. Scaphoid 2. Lunate

The ______________________ directly articulate with the distal end of the radius.

1. Scaphoid 2. Lunate

Bones of the wrist

Radiocarpal (wrist) joint is a _______________________ joint.

Condyloid - Biaxial
