Procoelous caudal vertebrae, a carpometacarpus with a hypertrophied metacarpal II, and robust proximal and ungual phalanges of manual digit II of a small theropod dinosaur from the Upper Cretaceous (Turonian) Bissekty Formation at Dzharakuduk, Uzbekistan, show unequivocal synapomorphies of the clade Alvarezsauridae and thus are referred to it. The caudal vertebrae have a unique longitudinal can...

Avulsion fractures of the radial wrist extensor from the metacarpal base are rare injuries, and have previously been reported in only a few papers. Although 2 cases of closed rupture of the extensor carpi ulnaris (ECU) were mentioned in 1 report, no case of avulsion fracture of the ECU from its insertion was found in the literature. We recently encountered such a case. The patient, a machine op...

The aim of this study was to assess the measurement of bone mineral density (BMD) by quantitative computed tomography (QCT), comparing the relationships of BMD between QCT and dual-energy X-ray absorptiometry (DXA) and between QCT and radiographic absorptiometry (RA) in the metacarpal bone of Holstein dairy cows (n=27). A significant positive correlation was found between QCT and DXA measuremen...

Carpo-metacarpal dislocations are rare traumatic injuries resulting from violent trauma; they mostly observed in young subjects. The spatular form is often accompanied by metacarpal fractures. We report a clinical case of complete dorsal carpo-metacarpal dislocation. This was 34-year-old patient, admitted for closed trauma the right hand, whom examination noted edema hand. radiological workup s...

Radiol Bras. 2014 Mar/Abr;47(2):VII Mass on the dorsal aspect of the wrist, either with or without associated pain, is a frequent complaint in orthopedic surgeon daily practice. In such cases, synovial or ganglion cyst is the most common diagnosis, but this is not the only diagnosis for that condition, so it is very important to know the differential diagnoses. Dorsal wrist mass may originate f...

The high demands placed on the upper extremity in sporting activities subject the competitive athlete to common injuries of the hand. Treatment options are based on the fracture configuration, associated extremity injuries, and status of the surrounding soft tissue. Metacarpal and phalangeal fractures may usually be treated by closed, nonoperative methods, and most athletes may quickly return t...

Formulae for the estimation of stature from metacarpal lengths are presented. Two samples of metacarpal specimens were employed in the analysis: one of 212 individuals from the Terry Collection, and one of 55 modern males, all of whom had measured statures. One measurement, the midline length, was taken on each metacarpal. Stature was regressed on the basis of the metacarpal length to derive eq...
