GENERAL CONSTRUCTION OF AN ARTIFICIAL LIMB
A prosthetic apparatus for any amputation is composed of two parts:
1. The artificial limb.
2. The attachment of this limb to the trunk.
The artificial limb itself is divided into two parts:
1. A conical socket.
2. A part which replaces the missing limb and is in fact a terminal functional appliance.
Two conditions must be considered, whether or not there remains attached to the trunk a segment of the limb capable of being fitted into the base of the artificial limb, to which it gives support, and to which, in addition, it can communicate movement. Accordingly the artificial limb differs essentially for:
1. Disarticulation of the shoulder and of the hip.
2. Amputation of the arm and of the thigh.
