background: the present study was designed to ascertain serial changes on distal radius radiographic parameters attributable to aging.       methods: in this prospective study, the sample consisted of 120 healthy individuals who were divided into four age groups each containing 15 males and 15 females. in the two below-20-year-old groups, only ulnar variance could be investigated. wrist radiogr...

conclusions this study did not show that distal radius anatomical indices including the radial height, radial inclination, ulnar variance and volar tilt influence perilunate fracture dislocation as risk factors. background distal radius radiographic indices may play a role as risk factors in pathogenesis of kienbock’s disease, scaphoid fracture and non:union:. perilunate fracture dislocations a...

Hand and wrist radiographic indexes such as radial inclination, ulnar variance, carpal height ratio, and radial tilt play an important role in the diagnosis and management of medical disorders, so they should be modified regarding the population and race difference. This study aims to compare the normal radiologic wrist indexes in Mashhad population with other existing databases and define some...

The aim of this study was to identify anatomic risk factors for scapholunate dissociation. On a PA view of the wrist, in zero position, the scaphoid and lunate diameter and height, lunate tilting angle, lunate uncovering index, lunate fossa inclination, radial inclination and ulnar variance were measured; on a lateral view the scapholunate angle and palmar tilting angle were measured. In a cont...

BACKGROUND Distal radius radiographic indices may play a role as risk factors in pathogenesis of Kienbock's disease, scaphoid fracture and nonunion. Perilunate fracture dislocations are devastating wrist injuries, and their relationship and distal radius indices have not been addressed in the literature. OBJECTIVES The aim of this study was to evaluate the possible role of distal radius radio...

background: fractures of distal radius are one of the most common fractures seen by physicians and account for 20% of all fractures seen in the emergency room. various factors contribute in secondary displacement of fracture fragments after anatomic or near anatomic close reduction and cast immobilization in distal radius fractures. this study was designed to examine the correlation between rad...

HD 45166 was selected as a candidate to the V Sagittae Class. It’s spectrum shows quite narrow emission lines of He, C, N, and O, possibly indicating a low inclination for the binary system. We performed high resolution and high stability Coudé spectroscopy in order to search for low amplitude radial velocity variations. The orbital period determined from the radial velocity curve is 0.357 days...

Ulnar variance and radial inclination are radiological parameters frequently used to evaluate displacement of distal radius fractures. In most studies measurements are based on the long central axis of the distal radius, although the axis of the distal ulna can also be used. The purpose of this study was to determine which axis is more reliable. Four observers performed measurements on standard...

Background As the triangular fibrocartilage complex (TFCC) anchors the distal radius to the ulna via the radioulnar ligament (RUL), a severely displaced distal fragment of the radius may be associated with a foveal avulsion of the TFCC. The purpose of this retrospective study was to assess, radiographically and arthroscopically, the relationship between displacement of the radius, the ulnar sty...

OBJECTIVE To determine the radiographic outcome in fractures of the distal radius treated with closed reduction and external fixation. DESIGN A retrospective study. SETTING The orthopedic department of National Taiwan University Hospital. PATIENTS Eighty-five consecutive patients (36 female, 49 male), average age 48 years, with fractures of the distal radius seen between March 1995 and Ju...
