The Compleat Surgeon / or, the whole Art of Surgery explain'd in a most familiar Method.

by M. Le Clerc

How are the Bones join'd together?

Two several ways, viz. by Articulation and Symphysis.

How many sorts of Articulations are there in the Bones?

There are generally two kinds, viz. Diarthrosis and Synarthrosis.

What is Diarthrosis?

Diarthrosis is a kind of Articulation which serves for sensible Motions.

How many kinds of Diarthroses, or great Motions are there?

There are Three, viz. Enarthrosis, Arthrodia, and Ginglymus.

Enarthrosis is a kind of Articulation which unites two Bones with a great Head on one side, and a large Cavity on the other; as the Head of the Thigh-Bone in the Cavity of the Ischion or Huckle-Bone.

Arthrodia is a sort of Articulation, by the means whereof two Bones are join'd together with a flat Head receiv'd into a Cavity of a small depth. Such is the Head of the Shoulder-Bone with the Cavity of the Omoplata or Shoulder-Blade; and that of the Twelfth Vertebra of the Back with the first of the Loins.
