[Descriptive, radiographic, topographic and functional anatomy applied to distal radius fractures].

Extensive anatomical knowledge is needed in order to correctly treat distal radius fractures: normal and pathological osteology of the distal radius, distal radio-ulnar joint and radiocarpal joint-both on the descriptive and functional level-the neurovascular and muscular environments of the distal radius-which are essential to the surgical approaches-and the angles that need to be restored during the reduction. All of these concepts are broached in this article.

[Osseous vascular anatomy in the hand and wrist].

The design and the realization of vascularized osseous grafts at the hand and the wrist require a precise knowledge of the general and regional anatomy. This article gives first a progress report on current knowledge about the general organization of arterial and venous vascularization, of the long bones (number and localization of the nutrient foramina, communication between the epiphyseo-metaphyseal and diaphyseal networks) and of the short bones, in the adult and the child, before the closing of the growth plate. The general organization of arterial vascularization of the hand and the wrist is pointed out, with the current nomenclature and the contribution of the recent publications, in particular in these, which relate to the distal extremity of the radius.

Retinacular disorders of the ankle and foot.

The retinacula of the ankle are distinct structures defined as regions of localized thickening of the crural fascia covering the deep structures of the distal portion of the leg, ankle, and foot. Their role is to maintain the approximation of the tendons to the underlying bone. The retinacula of the ankle and foot contain the extensor retinaculum, the peroneal retinaculum, and the flexor retinaculum.

Beyond the "science of sophomores": does the rational choice explanation of crime generalize from university students to an actual offender sample?

Much of the criminological literature testing rational choice theory has utilized hypothetical scenarios presented to university students. Although this research generally supports rational choice theory, a common criticism is that conclusions from these studies may not generalize to samples of actual offenders. This study proceeds to examine this issue in two steps.

Gas-liquid chromatographic determination of m-phenoxybenzyl cis, trans-(+/-)-3-(2,2-dichlorovinyl)-2-2-dimethylcyclopropanecarboxylate in aqueous formulations.

A simple and rapid gas-liquid chromatographic (GLC) method was developed for the analysis of aqueous solutions of FMC 33297 (mphenoxybenzyl cis,trans-(+/-)-3-(2,2-dichlorovinyl) - 2,2 - dimethylcyclopropanecarboxylate). The compound is extracted from aqueous solution with benzene and cleaned up by liquid chromatography. The sample extracts are analyzed by GLC with a flame ionization detector and quantitated by comparing integrator counts of extracts with those of standards.
