The fourth medical atlas in this new series on the human body and filled with detailed pictures, this atlas details the topographical and pathotopographical anatomy of the pelvis, spine, and limbs, a useful reference for medical professionals and students alike.

Written by an experienced and well-respected physician and professor, this new volume, building on the previous volume, Ultrasonic Topographical and Pathotopographical Anatomy, and its sequels, also available from Wiley-Scrivener, presents the ultrasonic topographical and pathotopographical anatomy of the pelvis, spine, and limbs, offering further detail into these important areas for use by medical professionals.

This series of atlases of topographic and pathotopographic human anatomy is a fundamental and practically important series designed for doctors of all specializations and students of medical schools. Here you can find almost everything that is connected with the topographic and pathotopographic human anatomy, including original graphs of logical structures of topographic anatomy and development of congenital abnormalities, topography of different areas in layers, pathotopography, computer and magnetic resonance imaging (MRI) of topographic and pathotopographic anatomy. Also you can find here new theoretical and practical sections of topographic anatomy developed by the author himself which are published for the first time. They are practically important for mastering the technique of operative interventions and denying possibility of iatrogenic complications during operations.

This important new volume will be valuable to physicians, junior physicians, medical residents, lecturers in medicine, and medical students alike, either as a textbook or as a reference. It is a must-have for any physician's library.

Part 1:
The Pelvis

Topographic Anatomy of the Pelvis

Limits. The pelvis is a part of the body located between the abdomen and lower limbs. It is limited outside by the pelvic bones, sacrum, coccyx and perineum at the bottom.

External reference points: the iliac crests (crista iliaca), anterior superior iliac spines (spina iliaca anterior superior), pubic tubercle (tuberculum pubicum), pubic symphysis, (symphysis pubica), dorsal surface of the sacrum (facies dorsalis os sacrum), tailbone (os coccyges); ischial tuberosity (tuber ischiadicum), the greater trochanter of the femur (trochanter major ossis femoralis), subpubicalis angle (angulus subpubicus).

Individual, Gender and Age Differences:

1. The individual features of the pelvis consist of different ratios of the longitudinal and transverse diameters of the pelvic ring. At one extreme type of variability, the longitudinal diameter is greater than the transverse one, the pelvis is “squeezed” from the sides, and the axes of the pelvic organs are often inclined to the sacrum. With a different type of variability, the longitudinal diameter is less than the transverse one, the pelvis is “compressed” in the anteroposterior direction, and the axes of the pelvic organs are inclined toward the pubic symphysis.
2. The gender differences. The wings of the iliac bones in women are more horizontal, therefore in women the pelvis is wider and lower than that of men. The inferior branches of pubic bones in women are located at an obtuse angle and form a pubic arch (arcus pubis); in men they are located at an acute angle and form a subpubic angle (angulus subpubicus). The pelvic cavity in women has the shape of a curved cylinder; in men it has the shape of a curved cone. The incline of the pelvis (inclination pelvis) is the angle between the horizontal plane and the plane of the superior aperture of the pelvis. In women it’s 55–60°, in men – 50–55°.
3. Age differences. By the time of birth, the pelvic consists of three parts, each of which has ossification centers. All three parts – iliac, ischial and pubic – are connected inter-layer cartilage in the area of the acetabulum. The iliac fossa is almost absent. By the age of seven, the size of the pelvic bone doubles, then the growth slows to 12 years. By the age of 13–18, parts of the pelvic bone coalesce, and their ossification ends. The synostosis of all elements of the hipbone is completed by the age of 25.

The walls of the pelvis. The pelvis is restricted to the pubic, iliac, ischium, sacrum and coccyx.

The pelvic floor is formed by the diaphragm of the pelvis (diaphragma pelvi) and partly by the urogenital diaphragm (diaphragma urogenitale).

The genitourinary diaphragm, diaphragma urogenitale (Figures 1–5) is formed by two muscles: the deep perineal transverse muscle and the external sphincter of the urethra.

The diaphragm of the pelvis is formed by two muscles: a muscle lifting the anus (m. levator ani) and the coccygeal muscle (m. soccygeus).

The floors of the cavity of the small pelvis. The cavity of the small pelvis is divided into three floors: upper one – peritoneum (cavum pelvis peritoneale), middle one – subperitoneal (cavum pelvis subperitoneale) and lower one – subcutaneous or perineal (cavum pelvis subcutaneum s. perineale).

Peritoneum in the male pelvis. In the male pelvis, the peritoneum from the anterior wall of the abdomen passes to the bladder, covering the upper wall and partly the lateral and posterior ones. On the sides of the bladder the peritoneum forms fossae paravesicales. At the symphysis level, the peritoneum forms plica vesicalis transversa. Going down the back wall of the bladder, the peritoneum covers the medial edges of the vas deferens and the apex of the seminal glands, and passes to the rectum, forming the recto-vesical pouch (excavatio rectovesicalis). The ampulla is covered on three sides, and the lower part of the rectum is not covered with the peritoneum at all.

Peritoneum in the female pelvis. In the female pelvis, the peritoneum also passes from the anterior abdominal wall to the bladder, forming a transverse fold, and then covers its superior and posterior walls. After this, it passes to the anterior surface of the uterus at the level of the isthmus, where it forms a shallow vesicouterine pouch (excavatio vesicouterina). On the anterior surface of the uterus, the peritoneum covers only the body of the uterus. On the posterior surface of the uterus, the peritoneum covers the body of the uterus, the supramarginal part of the cervix and the posterior vaginal vault and passes to the rectum, forming a deep recto-uterine pounch (the excavatio rectouterine) or Douglas’ pouch. It is limited by folds of the peritoneum – plicae rectouterinae, which extend to the anterior surface of the sacrum.

Fascia and cellular spaces, their connection with the cellular spaces adjacent regions. The parietal pelvic fascia (fascia pelvis parietalis) covers the anterior surface of the sacrum behind the back and is called the presacral fascia (fascia presacralis), on the sides it covers the parietal muscles (m. piriformis, m. obturatorius internus), the fascia of which have corresponding names (fascia obturatoria, fascia m. piriformis) in front – the posterior surface of the symphysis and the superior branches of the pubic bones, from below – the upper surface m. levator ani. The visceral pelvic fascia (fascia pelvis visceralis) lining the extraperitoneal parts of the pelvic organs in men and forms two sagittal branches extending from the pubic bones to the sacrum. Part of the visceral fascia that stretching from the pubic bone to the prostate gland in men or to the bladder in women is called the puboprostatic (lig. puboprostaticum) or pubovesical (lig. pubovesicale) ligament. These ligaments are accompanied by bundles of smooth muscle fibers of m. puboprostaticus and m. pubovesicalis.

The sagittal branches of the visceral fascia that located behind the bladder also...
