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...

in this paper, hardness and tensile properties of welded zone of aluminum 1100 alloys by friction stir welding process was investigated and the effects of rotational and traverse speeds of tool on these parameters was studied. also the fracture cross-section of welded samples was investigated. according the results of this paper, the hardness of weld material is higher than base material and is...

in this study, we examined the role of early acetazolamide administration in reducing the risk of cerebrospinal fluid (csf) leakage in patients with a high risk of permanent csf leakage. in a randomised clinical trial, 57 patients with a high risk of permanent csf leakage (rhinorrhea, otorrhea, pneumatocele or imaging-based evidence of severe skull-base fracture) were analysed. in the experimen...

Three separate impact events were simulated (LS-DYNA ® ) based on experimental tests previously conducted [2] (i.e., the appropriate impact velocities assigned to the model projectile): i) a pre-fracture event (2.1 m/s); ii) a crack event (2.7 m/s); and iii) a fracture event (3.3 m/s). Two element sets were created in the locations of the experimental strain gauges (dorsal radial styloid and do...

Dorsal fracture dislocations of the proximal interphalangeal joint with or without subsequent instability require a careful initial clinical examination followed by appropriate operative or nonoperative treatment. Attention to detail is crucial in achieving a successful outcome, regardless of the treatment selected. This article outlines the various classification systems available for dorsal f...

Distal radius (Colles') fractures are a common fall-related injury in older adults and frequently result in long-term pain and reduced ability to perform activities of daily living. Because the occurrence of a fracture during a fall depends on both the strength of the bone and upon the kinematics and kinetics of the impact itself, we sought to understand how changes in bone mineral density (BMD...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2015212133 DESCRIPTION A 50-year-old man fell on both outstretched hands, after jumping from a 2 m high fence. He supported his entire body weight on both palms. Immediately after the injury, he experienced mild pain, moderate limitation of movement and slight swelling of b...

The contribution of soft tissues in stabilizing fracture fixation in metacarpals is appreciated clinically, but no quantitative biomechanical study of their role has been done. All previous studies of fracture fixation in vitro have been done on metacarpals denuded of soft tissues. To quantify the role of soft tissues in metacarpal fracture fixation, the biomechanical effectiveness of four fixa...

BACKGROUND Distal radius fracture is a common injury and may result in substantial dysfunction and pain. The purpose was to investigate the relationship between distal radius fracture malunion and arm-related disability. METHODS The prospective population-based cohort study included 143 consecutive patients above 18 years with an acute distal radius fracture treated with closed reduction and ...

A 27-year-old male boxer presented with pain in the dorsum of right wrist and difficulty getting a firm grip on his hand for 2-month duration. On examination, he had swelling over dorsal aspect wrist. Physical examination revealed bony hard mass at junction third metacarpal capitate bones. The persisted despite conservative treatment patient was referred to our hospital further evaluation. Radi...
