FOREWORD

The best surgeons are those well versed in anatomy. A surgeon can never learn too much anatomy, but up until now,

he or she had to go to many sources to glean a broad base of

anatomical knowledge. My own career illustrates this point.

As a medical student, I began with Gray’s massive and dry

tome, learning anatomy for the sake of anatomy, with no

clinical relevance. Then, as a resident, I discovered

Hollinshead’s three-volume text that added functional implications. I also found, at that time, Henry’s classic book with

its quaint Irish-English prose and manual mnemonics. As a

young surgeon, I sought out books that would give me quick,

snapshot glimpses of anatomy that I could memorize and

carry in my head at least until the next day in the operating

room. Grant’s Atlas was the first of these, which was later

replaced on my shelf by McMinn and Hutchings’ magnificent atlas with its lifelike-quality color plates. Specialized texts

such as Sunderland and Spinner have described wonderfully

detailed and precise anatomy, but with a limited focus.

Now the hand and upper extremity surgeon has what all

of the above resources offered and more, packed into a single volume. The thoroughness of Gray, the practical applications of Hollinshead, and the clarity of McMinn and

Hutchings have been blended into one unified source.

More than sixty crisp photographic prints depict

detailed cadaver anatomy with a precision and clarity that

rivals McMinn. Most of the drawings were created by Elizabeth Roselius, a master among contemporary medical

illustrators. The exceptionally high quality of these illustrations is complemented by a text that is not only thorough,

but also replete with clinical applications.

Another pleasant surprise in this text is the appendix of

anatomic signs, syndromes, tests, and eponyms, where even

the surgeon who has studied the history of surgery will find

new or more accurate information. Practical lessons in the

Greek and Latin derivations of words explain why similarsounding words that evolve from separate sources have different meanings.

One of the authors, James R. Doyle, was the first to

describe in detail the flexor pulley system in the fingers

(1975) and later in the thumb (1977). Jim Doyle has studied the anatomy of the hand throughout his entire professional career with the eye of an artist who can perceive

details better than most of us, with an inherent tenacity fired

even harder during a fellowship year with Robert E. Carroll,

and with an exquisite and careful attention to detail. This

book is the culmination of his life-long dedication.

Michael Botte, his co-author, brings to this project the

thoroughness and precision of a true scientist, and his input

is significant. The collaboration of Doyle and Botte has produced a remarkable piece of work that will benefit not only

the entire surgical community, but our patients as well.

Every serious hand surgeon will find a readily accessible

spot on his or her bookshelf for this text.

PREFACE

Our goal has been to assemble between two covers a comprehensive collection of anatomical material designed to aid

the hand and upper extremity surgeon in the evaluation and

treatment of patients. A comprehensive knowledge of

anatomy is a major prerequisite for safe and effective

surgery. Although written by hand surgeons for hand surgeons, the authors believe that this text will also be useful to

hand therapists, anatomists, neurologists, neurosurgeons,

sports medicine surgeons and physicians, physiatrists, and

bioengineers because it is a compendium of anatomic

knowledge. The science of anatomy and the art of surgical

technique are intertwined topics that are not easily separated. Although this book is not designed as a text on operative surgery, overlap with surgical technique is inevitable,

appropriate, and complementary to the goal of the book.

Although another anatomy textbook may seem redundant, we hope the reader will agree that this text represents

a unique and current collection of material, which may not

be conveniently found elsewhere. Much of the information

can be found in other resources such as texts and journals

but we hope the reader, who like us has had difficulty recalling where we found a particular bit of information that we

now need to review or utilize in a timely fashion, will come

to value this comprehensive resource. Our primary goal in

this text is to provide a readily available source for this

information that is user friendly, easily portable, and clinically relevant.

We hope that the arrangement, clarity, and brief yet

comprehensive presentations of these topics will be of sufficient uniqueness to earn the designation of original, but we

readily admit that paraphrasing and adoption of others’

original concepts have been used (although we have done

our best to give credit where it was due). The words of Anatole France (passed on to us by Adrian Flatt) bear repetition

here, “When a thing has been said and said well, have no

scruples, take it and copy it.”

The text is divided into sections on Systems Anatomy

and Regional Anatomy, followed by an Appendix on

Anatomic Eponyms, Signs, Syndromes and Tests. The section on Regional Anatomy represents the practical component of this text because it provides the reader with

anatomic landmarks, relationships, surgical approaches,

clinical correlations, and the anatomy of selected anatomic

variations found in that region. The student of anatomy

will also recognize the immense value of the systems

approach, found in the section on Systems Anatomy, in

providing a comprehensive and overall view of a given

anatomic structure or system.

The authors take great pride in the color photographs of

fresh cadavers used in this text. A quote by Emanuel

Kaplan, about color photographs, from his foreword to

Milford’s 1968 classic monograph on Retaining Ligaments of

the Digits of the Hand seems appropriate here as well, “The

natural color illustrations add precision and eliminate the

imaginary interpretive creativity leading to error.” We hope

that the quality of our color photography can approach that

of Milford and warrant the affirmation of Kaplan on the

value of natural color photographs. We hope these color

photographs, along with the excellent illustrations, will

serve to make the anatomy in this text as realistic as possible. We also believe that the combination of these two art

forms along with the descriptive text will provide the reader

with appropriate information, which will permit accurate

preoperative evaluation, diagnosis, and effective surgical

treatment.

Anatomy, as a surgeon must deal with it, is three dimensional, but only two dimensions can be portrayed in a text.

This fact should immediately indicate to the reader that

there is no substitute for personal experience in the dissection room. In a two-dimension text, structures are often

portrayed as lying side by side when in reality they may be

vertically arrayed. A good example is the usual depiction of

the radial and ulnar arteries in the proximal forearm. The

ulnar artery is depicted as lying to the ulnar side of the

radial artery in the same anatomic plane whereas, in reality,

the ulnar artery is deep and ulnar to the radial artery and is

often difficult to find. The reader should also note that the

anatomic variations included are those that the authors perceive to have some practical clinical relevance to the region

and that the list of variations is not encyclopedic.

Reported differences in anatomy may be due to

anatomic variations as well as inter-observer variability and

subsequent interpretation of the observation. It would seem

reasonable to assume that all observers of a particular region

or segment of anatomy would see or observe the same

things and interpret what they saw in a similar uniform

fashion. Such is not the case, and although many points of

anatomy are agreed upon there are many that are not. Two

illustrative examples come readily to mind: (1) the arcade of

Struthers’ in the arm and (2) the location of the sesamoid

bones about the MP joint of the thumb. Some authors

describe in detail the arcade of Struthers’ 8 cm above the

medial humeral epicondyle and attach clinical significance

to it as a potential site of ulnar nerve compression in the

arm. Others claim that it does not exist or at least that they

have never seen it and thus it has no clinical relevance. The

location of the ulnar and radial sesamoid bones about the

MP joint of the thumb have been reported to be in the

adductor pollicis and flexor pollicis brevis tendons respectively or in the palmar plate where they possess articular cartilage and articulate with the thumb metacarpal; two

entirely different pictures of the same structures. Interobserver variability may be illustrated by the imperfect, yet

humorous, analogy of six blind persons examining a camel.

Each of their descriptions are based upon their particular

location about the camel. Their significant inter-observer

variation results in a series of descriptions that would confound even a camel veterinarian. The authors include themselves in those observers who may be subject to imperfect

observation as well as faulty interpretation. Thus, there may

be a lively correspondence and commentary generated by

this text.

We believe that studies that have large numbers of specimens in their data base have a greater potential for reflecting what might be considered more common and thus

likely to be encountered in the day to day practice of

surgery. Studies with small numbers of specimens in which

several patterns or categories of anatomical arrangement are

noted tell us that significant variation exists. It may not tell

us the true incidence of a given pattern or arrangement in

spite of the authors’ conscientious reporting of one, two, or

three cases in their series which demonstrated a particular

pattern or arrangement. Such studies though, are still

important and tell us that significant variation exists in that

particular structure or region and that the surgeon must be

prepared to encounter such an arrangement or even a new

and unreported pattern or arrangement.

By now, the reader has begun to appreciate the fact that

anatomy is not a “fixed” science, but rather an evolving or

developing endeavor with many remaining challenges and

opportunities.

All authors have their own methods for placing thoughts

on paper. This quote from Wallace Stegner1, although

directed at the writer of autobiography or fiction, seems

appropriate, “You take something that is important to you,

something you have brooded about. You try to see it as

clearly as you can, and to fix it in a transferable equivalent.

All you want in the finished print is the clean statement of

the lens, which is yourself, on the subject that has been

absorbing your attention.”

The authors wish to recognize their debt to those surgeons and anatomists who have studied and described their

anatomic findings in the upper extremity and to our many

mentors and colleagues who have taught, encouraged, and

inspired us.

Finally, the authors wish to acknowledge their debt to

Robert Hurley and Keith Donnellan of the editorial staff at

Lippincott Williams & Wilkins who have patiently guided

and encouraged us throughout this process in such a competent and professional manner. We also owe a great debt to

Elizabeth Roselius, medical artist, for her understanding of

complex anatomic concepts and her ability to convert those

concepts into clear and concise drawings.
