OBJECTIVE To compare the clinical and radiographic results from osteosynthesis of fractures of the lateral third of the clavicle, using two methods: T plates or anchors together with Kirschner wires. METHODS Fifteen patients of mean age 34.3 years (range: 19-57) and mean follow-up 22.7 months (range: 14-32) were evaluated. In nine cases, a T plate was used; and in six cases, coracoclavicular ...

In this paper, I give the English progressive a semantic analysis as an intensional operator within the framework of modal semantics proposed by Kratzer. This treatment allows a combination of the central idea of Dowty’s influential analysis, that the progressive’s meaning has a major modal component, with the insights of other scholars (Parsons, Vlach, and Landman). My claim is that using a mo...

Kirschner, Sweller, and Clark (2006) suggest that unguided or minimally guided instructional approaches are less effective and efficient for novices than guided instructional approaches because they ignore the structures that constitute human cognitive architecture. While we concur with the authors on this point, we do not agree to their equation of problem-based learning with minimally guided ...

Intrapelvic migration of a Kirschner wire, used in the treatment of hip fracture, is rare. We report a case of intrapelvic migration of a Kirschner wire 10 years after its placement. Even though the patient was asymptomatic, we proceeded to remove the migrated wire using laparoscopic techniques. Given the increasing number of hip operations being performed, and given that intrapelvic foreign bo...

A graph G = (V,E) is a threshold tolerance graph if each vertex v ∈ V can be assigned a weight wv and a tolerance tv such that two vertices x, y ∈ V are adjacent if wx +wy ≥ min(tx, ty). Currently, the most efficient recognition algorithm for threshold tolerance graphs is the algorithm of Monma, Reed, and Trotter which has an O(n) runtime. We give an O(n) algorithm for recognizing threshold tol...

Migrating orthopedic hardware has widely been reported in the literature. Most reported cases of migrating hardware involve smooth Kirschner wires or loosening/fracture of hardware involved with joint stabilization/fixation. It is unusual for hardware to migrate within the soft tissues. In some cases, smooth Kirschner wires have migrated within the thoracic cage-a proposed mechanism for this ph...

The well-known Kirschner-Panetta model for tumour-immune System interplay [Kirschner, D., Panetta, J.C., 1998. Modelling immunotherapy of the tumour-immune interaction. J. Math. Biol. 37 (3), 235-252] reproduces a number of features of this essential interaction, but it excludes the possibility of tumour suppression by the immune system in the absence of therapy. Here we present a hybrid-stocha...
