This is unusual in that the subject matter is unusual, particularly to the American surgeon who, probably because of less extensive experience with amputations than his European colleague, has given little or no thought to kineplastic procedures on amputation stumps. The work opens with an interesting historical introduction; next follows a chapter on the surgery of amputations. The mechanics of various joints and muscles and their relations to various types of protheses are next described. A large part of the book is devoted to an extensive cataloguing of the various types of artificial limbs and their mechanics. These are profusely illustrated by excellent reproductions of photographs. The book is not bulky, and was not intended as a complete encyclopedic work. It has many interesting surprises for the average surgeon not familiar with recent advances in the development of artificial prostheses.
