Triaxial plane joint

What are the motions of the sternoclavicular joint?

What is the classification for the acromioclavicular joint?

Triaxial plane joint

What are the motions of the acromioclavicular joint?

Tilt (anterior/posterior)- Sagittal plane, coronal axis Upward/downward rotation- frontal plane, A-P axis Internal/external rotation- transverse plane, vertical axis

What is the classification of the scapulothoracic joint?

Not a true diarthrodial joint. No bones moving on bones.

What are the motions of the scapulothoracic joint?

Scapula moves around rib cage Upward /downward rotation- frontal plane, A-P axis. Protraction/retraction (hugs)- transverse plane, vertical axis. Elevation/depression- Sagittal plane, coronal axis.

What is the classification of the glenohumeral joint?

Triaxial ball-and-socket joint

Are all motions of the glenohumeral concave on convex or convex on concave?

Convex on concave

What is the normal scapulothoracic position?

2 inches from midline Lies between 2nd and 7th rib. Tilted forward 10-20 degrees from the vertical. 30-40 degrees forward of the frontal plane.

What is the scapulothoracic position called?

The plane of the scapula-where the scapula sits.

What is scaption?

Elevation in the plane of the scapula

Which way does the numeral head face?

Medially, superiorly, posteriorly

What is the angle of inclination?

The axis through the head and the axis through the shaft create approximately 135 degree angle

What is the angle of torsion?

The axis through the humeral head and the axis through the humeral condyles form a 30 degree angle posteriorly.
