Fractures of the thumb metacarpal occur most frequently at the base. These fractures can be subdivided into intra-articular and extra-articular types. Intra-articular fractures present treatment challenges because they have a tendency to displace due to deforming forces acting at the base of the thumb. An understanding of the anatomy, biomechanics, and fracture pattern will aid in deciding on t...

Offset-dependent characteristics of seismic scattering are useful in the interpretation of fractured reservoirs. Synthetic seismograms generated by a 3-D finite difference modeling are used to study elastic wave propagation and scattering in heterogeneous fraetmed reservoirs. We use two models having different background medium properties and different azimuthal AVO responses and build heteroge...

A 45-year-old woman presented to the emergency department with left wrist pain following a fall. Physical exam was remarkable for soft tissue swelling of the palmar and dorsal hand, point tenderness at the base of the second metacarpal, and limited active range of motion. Three-view wrist radiographs showed significant soft tissue swelling without evidence of fracture or dislocation. Computed t...

Association of fracture of trapezium with Bennett's fracture is very rare and makes reduction and stabilisation more difficult. We are reporting a rare case of Bennett's fracture with fracture of the trapezium and subluxation of the carpo-metacarpal joint (CMC) joint. The patient was a 47-year-old school teacher who fell from his motorbike on his outstretched right dominant hand. Radiographs an...

We report the cases of two men aged 35 and 33, who presented with similar injuries following a fall. They presented with pain isolated to the area of the index finger metacarpal base. Radiographs demonstrated an index metacarpal base fracture with a similar large ulnar-sided articular fragment extruded vol-arly. In the first patient the fragment was immediately adjacent to the remaining metacar...

Three fractures at the base of the terminal phalanx of the finger and one at the base of the terminal phalanx of the tow were initially misdiagnosed as paronychias. If a 'paronychia' follows trauma, the possibility of a fracture should be considered and radiographs taken of the digit.

J.H., a man aged 24 years, was knocked down by a car and admitted to hospital on January 13, 1961. His injuries were:a comminuted fracture of ,he mid-shaft of the right femur, an open comminuted fracture of the shaft of the right tibia, a fractured right fibula, a rupture of the anterior cruciate ligament of the right knee, and a fracture of the base of the terminal phalanx of the right hallux....

Moisture flow in porous media is the driving force behind early age drying shrinkage. Fracture in the interfacial transition zone (ITZ), between cement paste and aggregateinclusion, is related to restraint caused by, among others, aggregates that obstruct free deformation of the paste. Environmental Scanning Electron Microscope (ESEM) test results are used as a base for the developed method for...
