Developments in trapezium Replacements
The purpose of this update is to report on a variety of topics related to trapezium implants that have been investigated during the past three years. The keyword trapezium implant was utilized to query the PubMed database of the U.S. National Library of Medicine. From the resulting list, papers published from the beginning of January 2012 through the beginning of April 2015 were reviewed. The t...
متن کاملAn Expanding Trapezium Cluster?
Simulations with Aarseth's (1994) NBODY5 code are presented of an initially dense binary-rich cluster. It is assumed that the star formation efficiency is 50 per cent with instantaneous mass loss. The model central density and velocity dispersion agree with the observational constraints if expansion is only about 6 × 10 4 yr old. Additionally, the observed binary proportion constrains the primo...
متن کاملIsolated dislocation of the trapezium.
A 31-year-old housewife attended the Accident and Emergency Department of the Mater Infirmorum Hospital, Belfast, Northern Ireland, having fallen and injured her left wrist. She had fallen backwards onto her outstretched hand, forcing the wrist into considerable dorsi-flexion with the forearm in supination. Examination revealed bruising and swelling at the base of the first metacarpal and over ...
متن کاملMassive Protoplanetary Disks in the Trapezium Region
We determine the disk mass distribution around 336 stars in the young (∼ 1 Myr) Orion Nebula cluster by imaging a 2. 5 × 2. 5 region in λ3 mm continuum emission with the Owens Valley Millimeter Array. For this sample of 336 stars, we observe 3 mm emission above the 3σ noise level toward ten sources, six of which have also been detected optically in silhouette against the bright nebular backgrou...
متن کاملOpen Reduction and Fixation of Trapezium Fracture
Fractures of trapezium are very rare accounting for about 0.4% of the hand’s injuries [1]. However, they should not be missed because inadequate treatment of trapezium fractures can lead to permanent impairment based on the substantial forces experienced at the trapeziometacarpal (TMC) joint in pinch and grip [2]. When present, often result of high energy trauma and occur in association with ot...
