INTRODUCTION Biomechanically proximal femoral nail (PFN) is a better choice of implant, still it is associated with screw breakage, cut out of screw through femoral head, Z effect, reverse Z effect, and lateral migration of screws. The purpose of this study is to evaluate the results of augmented PFN in terms of prevention of postoperative complications and failure rates in unstable trochanteri...

Surface replacement of the hip was introduced as an alternative to conventional replacement. Unfortunately, its theoretical advantages have been overshadowed by the high incidence of early failure (Head 1981 ; Jolley, Salvati and Brown 1982; Bell et al. 1985). If failure necessitates removal of the prosthesis, we advocate preservation of the femoral neck stump for articulation. We report five s...

carpal tunnel syndrome (cts) is considered by researchers because of its high prevalence, and several studies have been done to find the causes and factors which increase the chance for the syndrome. these studies have shown relationships between this syndrome with some physical parameters like wrist dimensions, weight and systemic conditions. there is no investigation on risk factors in cts in...

PURPOSE To assess inter- and intra-observer errors in identifying the transepicondylar axis and Whiteside's line in a cadaveric model mimicking total knee arthroplasty. METHODS Four cadaveric knees with intact soft tissues were used. The knees were exposed anteriorly using the Insall approach, with the patella everted laterally. Three observers (2 surgeons and one trainee) took turns to ident...

There has been a growing appreciation over the last decade that chemotaxis plays an important role in cancer migration, invasion and metastasis. Research into the field of cancer cell chemotaxis is still in its infancy and traditional investigative tools have been developed with other cell types and purposes in mind. Direct visualisation chambers are considered the gold standard for investigati...

From 1981 through 1991, 3,032 primary total knee arthroplasties were performed using the Insall-Burstein Posterior Stabilized Condylar Prosthesis (IB-I, IB-II, and IB-II modified) (Zimmer, Warsaw, IN). Fifteen posterior dislocations occurred: 4 with the IB-I system occurring 2 or more years after surgery, 10 with the IB-II system (8 occurring 6 months after surgery and 2 occurring 2-3 years aft...

In Dictyostelium discoideum, AprA is a secreted protein that inhibits proliferation and causes chemorepulsion of Dictyostelium cells, yet AprA has little sequence similarity to any human proteins. We found that a predicted structure of AprA has similarity to human dipeptidyl peptidase IV (DPPIV). DPPIV is a serine protease present in extracellular fluids that cleaves peptides with a proline or ...

One of the central changes in 20th century linguistics was the reconceptualization of language as a cognitive ability rather than merely an abstract relational system of signs — in the terminology of Chomsky (1986), the move from E-language to I-language. This shift entails that linguistic theory is no longer measured exclusively by empirical coverage, succinctness of description, and conceptua...
