BACKGROUND Volar Barton's fractures are not uncommon but more convincing treatment methods are still controversial. Currently, open reduction with buttress plating or closed reduction with external fixation and percutaneous Kirschner wire fixation have achieved most support. METHODS Twenty-three consecutive volar Barton's fractures treated with either open reduction and buttress plate fixatio...

The purpose of this paper is to introduce a simple and intuitive treatment method using an 18-gauge needle for mallet fractures that involve more than one-third of the articular surface. We performed a retrospective review of 17 patients who underwent closed reduction using an 18-gauge needle with transfixation of Kirschner wire between March 2007 and October 2013. According to the Wehbe and Sc...

Mallet fingers with an avulsion fracture of the distal phalanx or rupture of the terminal tendon of the extensor mechanism is known as a common injury, while mallet thumb is very rare. In this paper, the case of a 19-year-old woman with a sprained left thumb sustained while playing basketball is presented. Plain radiographs and computed tomography revealed an avulsion fracture involving more th...

Carpal fractures in children are rare, especially with a combination of scaphoid, capitate, and triquetrum fractures. We report one such case in a 10-year-old boy who was successfully treated with Kirschner wires.

Computer Supported Collaborative Learning (CSCL) incorporates collaborative learning activities and communication between participants and among groups via networked computers, where interactions can be synchronous or asynchronous (Naidu & Ja ̈rvela, 2006). The ubiquitous characteristic of CSCL environments, combined with their interactive group learning capabilities is becoming more and more im...

Congenital pseudarthrosis of the clavicle (CPC) is a rare malformation of uncertain aetiopathogenesis, usually unilateral. Physical examination reveals swelling over the midportion of the clavicle, often asymptomatic; the diagnosis is confirmed by radiology. Treatment is controversial: for many authors the surgical indications are the presence of symptoms, functional impairment or cosmetic defo...

Distal radius fractures are the most common fractures in the elderly, yet the treatment is controversial and still debated in the literature. Twenty four patients aged older than sixty with distal radial fractures were treated by dorsal nail plate. We compared them with twenty four similar matched patients treated by percutaneous Kirschner wiring surgical method. The patients were operated on b...

Two years before WADS began, my father Martin Demaine and my six-year-old self designed and made puzzles as the Erik and Dad Puzzle Company, which distributed to toy stores across Canada. So began our journey into the interactions between algorithms and the arts. More and more, we find that our mathematical research and artistic projects converge, with the artistic side inspiring the mathematic...
