INTRODUCTION Traumatic dislocation of the radial head in paediatric population is a well described injury, it is usually associated with an injury to the ulna in the Monteggia lesion (1), but can occur as an isolated injury also (2,3). CASE REPORT A 4.5 year old girl presented to emergency department with her right upper limb held in pronation and flexion following isolated closed injury. Roe...

Isolated dislocation of the trapezium is an uncommon injury. There are sixteen cases to date reported in the literature. The management of these cases has varied from complete excision to open or closed reduction, with or without percutaneous wiring. This paper presents a case of an isolated dislocation of the trapezium without fracture, managed with closed reduction and percutaneous wiring, re...

Lisfranc fracture dislocations are an often misdiagnosed injury pattern, which if left unreduced can lead to signifi cant disability (1-5). The articulation between the bases of the 5 metatarsals, cuneiforms, and cuboid has been termed the Lisfranc joint (6, 7). Lisfranc joint represents a junction between the forefoot and the midfoot. Three functional columns make up the tarsometatarsal area, ...

Background. Acromioclavicular (AC) joint dislocation is a common shoulder problem. However, information about the basic epidemiological features of this condition is scarce. The aim of this study is to analyze the epidemiology of isolated AC dislocation in an urban population. Materials and Methods. A retrospective database search was performed to identify all patients with an AC dislocation ov...

The displacement field around an isolated elementary dislocation in a medium with one-dimensional periodicity is established experimentally. The system studied is a cholesteric fingerprint texture with a macroscopic ( approximately 10 microm) periodicity. The characteristic elastic length is smaller than the "interlayer" distance. As a result, the experimental dislocation profile deviates from ...

INTRODUCTION Isolated dislocations of the trapezio metacarpal joint without associated fracture has been reported very rarely in the literature. There are reports of associated injuries like fracture of the trapezium, dislocation of the metacarpophalangeal joint and fractures of the base of the thumb metacarpal. CASE REPORT Authors report a case of isolated carpometacarpal dislocation of the ...

The post-traumatic dislocation of the fifth-finger is a rare lesion. In the absence of treatment, this lesion results in joint degeneration and instability. This lesion is usually unstable, treated by open, Closed. We report the case of a carpal-metacarpal dislocation isolated palmar pure in a boxer, clinically the patient presented a disturbance of rotation of 15° with a shortening of 5 mm. Th...

A cuboid structure was constructed using a DNA origami design based on a square prism structure. The structure was characterized by atomic force microscopy (AFM) and dynamic light scattering. The real-time opening event of the cuboid was directly observed by high-speed AFM.

Selective attention determines the effectiveness of implicit contextual learning (e.g., Jiang and Leung, 2005). Visual foreground-background segmentation, on the other hand, is a key process in the guidance of attention (Wolfe, 2003). In the present study, we examined the impact of foreground-background segmentation on contextual cueing of visual search in three experiments. A visual search dis...
