This project correlates the detailed radiographic anatomy of the entire adult foot and ankle two-dimensional to osteology three-dimensional. The normal gross and radiographic anatomy is correlated and described for each radiographic positioning technique.

The results of the original project, owing to its broad scope, have been divided into five parts: the lower leg, the greater tarsus, the lesser tarsus, the metatarsals, and the phalanges the focus of this article. J Am Podiatr Med Assoc 2 : , Introduction, Methods, Discussion The Introduction including the literature review , Methods, and Discussion were previously described in part 1 of this series of articles.

Results Hallux Distal Phalanx Osteology. The distal phalanx is composed of three sections: ungual tuberosity, shaft, and base. The ungual tuberosity is at the distal end of the phalanx. It is primarily positioned anteroinferiorly. The inferior aspect extends more posteriorly than does its superior aspect. The entire tuberosity is rough and perforated by numerous small foramina.

The posteroinferior border is jagged but concave. The inferolateral and inferomedial corners are occasionally pointed and are referred to as spines. The lateral interosseous ligaments insert onto the ungual spines. The shaft has superior and inferior surfaces and medial and lateral borders. The superior surface is flat longitudinally and convex transversely. It extends to the anterior tip of the phalanx. The superior surface is very smooth and is covered by nail bed mesenchyme. The lateral border of the shaft is concave; the medial border is less concave, relating to the normal fibular angulation of the diaphysis to the base.

The girth of the shaft is narrower anteriorly. A large tuberosity hereafter called the flexor tuberosity is found along the flat inferior surface of the shaft near the base. It runs obliquely across the shaft from posteromedial to anterolateral, ending near the middle of the shaft. The flexor hallucis longus tendon inserts here. Tubercles are found along the inferomedial and inferolateral aspects of the base at the junction with the shaft.

The inferomedial tubercle is larger and more defined. The lateral interosseous ligaments originate from these tubercles and insert onto the ungual spines. The nail bed vessels pass between these ligaments and the phalanx shaft. The posterior articular surface is convex transversely and concave vertically. A small beak protrudes from the central aspects of the superior and inferior borders.

Radiographic Anatomy. Dorsoplantar Foot View Weightbearing Fig. The well-defined anteriad, mediad, and laterad margins of the ungual tuberosity correspond to its anterior, medial, and lateral aspects, respectively.

These margins usually appear smooth. However, they can be quite irregular as a variation of normal. A somewhat well-defined and transverse, curvilinear increased density demarcates the posteriad extent of the ungual tuberosity; this represents the superimposed posteroinferior border of the ungual tuberosity.

The posterosuperior border cannot be identified. The mediad and laterad margins of the shaft correspond to its medial and lateral aspects, respectively. The laterad margin is more concave than the mediad margin. Very little cortical bone is seen. The base is the widest section of the distal phalanx. The inferomedial tubercle is frequently identified and projects anteromediad. This tubercle can range in size from tiny to large. It should not be mistaken for an abnormal exostosis.

The inferolateral tubercle generally is not visible. Spur formation at the lateral interosseous ligament entheses is not uncommon.

The crescentic, welldefined increased density at the posteriad margin of the base represents the superior aspect of the articular surface. The inferior aspect of the articular surface projects more posteriad than the superior aspect. It can be identified centrally, superimposed Figure 1. Hallux distal phalanx. A, Dorsoplantar view dorsal perspective, radiograph, plantar perspective ; B, lateral view lateral perspective, radiograph, medial perspective ; C, medial oblique view superolateral perspective, radiograph, inferomedial perspective ; D, lateral oblique view superomedial perspective, radiograph, inferolateral perspective.

An ill-defined sclerosis runs transversely, adjacent to the center of the posteriad margin. This corresponds to the crest along the superior surface. Lateral Foot View Weightbearing Fig. The superiad, anteriad, and inferiad margins of the ungual tuberosity correspond to its superior, anterior, and inferior aspects, respectively.

Its posterior borders can be identified both superiad and inferiad. They each begin where the cortical bone of the shaft ends. The superoposterior border is near the tip of the phalanx; a small spur may sometimes be seen at this location. The inferoposterior border is more posteriad. The superiad and inferiad margins of the shaft correspond to its superior and inferior surfaces, respectively.

The superiad margin is smooth and flat anteriad and slightly concave posteriad. The inferiad margin is concave anteriad and convex posteriad. The convexity along the inferiad margin corresponds to the flexor tuberosity.

Cortical bone can be identified along both margins between the base and ungual tuberosity. The superiad margin of the base corresponds to its superior crest. The inferiad margin corresponds to the inferomedial aspect of the base, including the medial tubercle. The remainder of the base cannot be clearly identified.

It is superimposed on the second toe. The anteriad margin of the ungual tuberosity corresponds to its superomedial, anterior, and inferolateral aspects. The posteroinferior border is superimposed but can be identified. It appears as an ill-defined sclerosis running in an oblique direction that separates the ungual tuberosity from the shaft and its medullary cavity. Both margins are concave. The anterolateral aspect of the flexor tuberosity can be seen along the laterad margin.

It mimics a periosteal reaction. The superomedial aspect of the inferomedial tubercle is seen along the mediad margin of the base. The posteriad margin corresponds to the posterior articular surface.

The triangular-shaped shadow that is seen in the center of the proximal phalanx head represents the superimposed inferior aspect of the posterior surface. A concave, curvilinear density is seen anteriad to this structure, forming the base of an apparent triangle.

This is the superolateral aspect of the articular surface. The superomedial and medial aspects of this surface are superimposed on each other mediad. A U-shaped increased density is seen in the metaphysis. This corresponds to the superimposed posterior aspect of the flexor tuberosity. The anteriad margin of the tuberosity is crescent-shaped. The posteroinferior aspect is superimposed but can be identified as an ill-defined sclerosis that separates the tuberosity from the shaft.

The mediad and laterad margins of the shaft correspond to its inferomedial and superolateral aspects, respectively. Both surfaces are concave. It is larger than the inferolateral tubercle isolated with the medial oblique view. The articular surface for the proximal phalanx is viewed posteriad. The triangular-shaped shadow that extends onto the proximal phalanx head represents the superimposed inferior aspect of the articular surface.

A linear increased density is seen anteriad to this shadow. This is the superomedial aspect of the articular surface. The remainder of the posteriad margin corresponds to the lateral aspect of the joint surface. Hallux Proximal Phalanx Osteology. The proximal phalanx is composed of a head, shaft, and base. The head presents a trochlear articular surface with medial and lateral shoulders inferiorly. It is concave transversely and convex vertically. A fossa is found between the shoulders inferiorly, posterior to the articular surface.

Interphalangeal and phalangeoglenoid ligaments insert onto tubercles along the superomedial and superolateral aspects of the head, posterior to the articular surface.

 - Он потянулся к клавиатуре.  - Мистер Беккер, пожалуйста, продиктуйте надпись. Медленно и отчетливо.

Поскольку компьютеры находились во включенном состоянии круглые сутки, замок позволял криптографам покидать рабочее место, зная, что никто не будет рыться в их файлах. Сьюзан ввела личный код из пяти знаков, и экран потемнел. Он будет оставаться в таком состоянии, пока она не вернется и вновь не введет пароль. Затем Сьюзан сунула ноги в туфли и последовала за коммандером.

 Хорошо. Полагаю, вы получили обе копии ключа. - Вышла небольшая заминка, - сказал американец. - Это невозможно! - рявкнул Нуматака.  - Вы обещали, что они будут у меня сегодня до конца дня.

Она вспомнила свою первую реакцию на рассказ Стратмора об алгоритме, не поддающемся взлому. Сьюзан была убеждена, что это невозможно. Угрожающий потенциал всей этой ситуации подавил. Какие вообще у них есть доказательства, что Танкадо действительно создал Цифровую крепость.

Внизу угрожающе мигала команда: ВВЕДИТЕ КЛЮЧ Вглядываясь в пульсирующую надпись, она поняла. Вирус, ключ, кольцо Танкадо, изощренный шантаж… Этот ключ не имеет к алгоритму никакого отношения, это противоядие.
