Background: Atlantoaxial transarticular screw fixation is considered to be the “gold standard” for treating atlantoaxial instabilities. This challenging surgical procedure requires high skills and appropriate surgical armamentarium. Such conditions are rarely met in sub-Saharan Africa. After a thorough review of medical literature, we did not find a single report on atlantoaxial transarticular ...

PURPOSE Tibial fracture is the most common long bone fracture. Distal third tibial fractures are challenging though open reduction and plating can result in anatomical reduction and rigid fixation. This paper aimed to evaluate and compare the results of medial and lateral locking compression plates for distal third tibial fractures. METHODS This prospective clinical study involved 36 patients...

Cathodic activation examined with reference to the cold fuslon developments (controversy). Historically cathodic activation has been used for plating preparation of p a s s i v e (o x i d e) s u r f a c e s e.g. nickel/chromium alloys, niobium and powdered metals. More recent results of work employing cathodic activation for preparing aluminum for plating will be presented e.g. process paramete...

In the previous chapter, the components of electroless nickel plating baths were discussed from the viewpoint of the function each performs in the bath, with little attention paid to their effect on the plating process. The metal and the electron source (the reducing agent) are consumed in the electroless plating reaction and so their concentrations in the bath are continuously decreasing. Ther...

Objectives: This study aimed to measure non-destructively gold (Au) electrodeposited on a high-gold alloy by modulating coating time and comparing this sputtering Au known thicknesses. Methods: was (plated) 11 plates (A–K) at 2.8V between 20 220 min. Seven strips were sputter coated the same thicknesses (range 50–500 nm). Energy dispersive X-ray spectroscopy (EDS) used minimal electron energy (...

A high-efficiency waveguide slot array antenna with low sidelobe level (SLL) is investigated for W-band applications. The silicon micromachining technology utilized to realize multilayer architecture by three key steps of selective etching, gold plating and Au-Au bonding. radiating based on this technique becomes thick a minimum thickness 0.2 mm accompanies the decrease slot's radiation ability...

BACKGROUND The position of plate fixation for clavicle fracture remains controversial. Our objective was to perform a comprehensive review of the literature and quantify the surgical parameters and clinical indexes between the anterior inferior plating and superior plating for clavicle fracture. METHODS PubMed, EMBASE, and the Cochrane Library were searched for randomized and non-randomized s...

BACKGROUND AND PURPOSE Although plating is considered to be the treatment of choice in distal tibia fractures, controversies abound regarding the type of plating for optimal fixation. We conducted a systematic review to evaluate and compare the outcomes of locked plating and non-locked plating in treatment of distal tibia fractures. PATIENTS AND METHODS A systematic review was conducted using...

Many laboratories are experiencing growing shortages of trained microbiology technologists and technicians. Consequently, there is considerable interest in new automation that could potentially lessen labor demands for specimen processing. In this study, we present the first published evaluation of a new microbiology instrument, the Walk Away Specimen Processor (WASP), manufactured by Copan, In...

BACKGROUND To compare risk of carpal tunnel syndrome (CTS) in distal radius fracture (DRF) patients after 7 treatments using bridging external fixation (BrEF), non-bridging external fixation (non-BrEF), plaster fixation, K-wire fixation, dorsal plating fixation, volar plating fixation, and dorsal and volar plating by performing a network meta-analysis. MATERIAL AND METHODS An exhaustive search ...
