Background: Previous anatomic and radiological studies have described the relationship of the clavicle to major neurovascular structures in healthy subjects. We were curious about this relationship in patients with a clavicle fracture and if it is different from non-fractured clavicles.   Methods: We retrospectively identified all patients with a clavicle fracture between July 2001 and Octobe...

This study aimed to evaluate the ability of speed of sound (SOS) measured at the phalanges to estimate simulated wrist fracture load and stress. SOS was measured along the proximal phalanges of the second, third and fourth fingers using an ultrasound (US) system operating in axial transmission mode. The bone mineral density (BMD) of the radius and the phalanges was also measured with quantitati...

We investigated the relationship between fetal body weight at term (pregnancy day 21) and the extent of ossification of sternum, metacarpus, metatarsus, phalanges (proximal, medial and distal) of fore- and hindlimbs and cervical and coccygeal vertebrae in Wistar rats. The relationships between fetal body weight and sex, intrauterine position, uterine horn, horn size, and litter size were determ...

sternum, spine, ilium, carpus, metacarpus, phalanges of fingers, tarsus, metatarsus, and phalanges of toes. Tubercular affections of the skin.?Such as lupus. Tubercular disease of membranes.?Such as pleurisy, peritonitis, and meningitis. Tubercular disease of certain organs.?Such as the kidneys, testis, tonsils, larynx and even tubercle of lung, considering that the best treatment for it at one...

Oblique radiograph of the hand and wrist demonstrates multiple radiolucent, expansile masses of varying shapes in the phalanges, metacarpals, radius, and ulna. Figure 2. Anteropost...

The partial skeleton of Pierolapithecus, which provides the oldest unequivocal evidence of orthogrady, together with the recently described phalanges from Paşalar most likely attributable to Griphopithecus, provide a unique opportunity for understanding the changes in hand anatomy during the pronogrady/orthogrady transition in hominoid evolution. In this paper, we describe the Pierolapithecus h...

Unicameral bone cysts (UBC) and aneurysmal bone cysts (ABC) are benign cystic lesions of bone which are easily diagnosed. However, unusual locations may lead to a false diagnosis. Therefore the aim of this retrospective study was to determine the frequency of unusual localizations. The authors studied 451 cases with histopathologically confirmed diagnosis of UBC or ABC, seen between 1981 and 20...

Histological and anthropometric studies were made of the hands and face of a 17-week-old (postmenstrual) human fetus that was exposed to warfarin throughout gestation. The fetus had marked nasal hypoplasia and the facial cartilages contained discrete foci of abnormal cartilage. When compared with age-matched control fetuses hand pattern profile analysis showed that the brachydactyly was due to ...

We propose an actuator for multi-fingered grippers for industrial robots built around fluid-powered bladders enclosed within the structure of the phalanges themselves. Unlike a normal hydraulic cylinder where the available force is a function of the height and width of the phalanges, in this configuration, the force the fingers can generate becomes a function of the length and width of the phal...
