Factors Affecting Transfusion Requirement After Hip Fracture: Can We Reduce The Need For Blood?, Sagar J. Desai, Kristi S. Wood, Jackie Marsh, Dianne Bryant, Hussein Abdo, Abdel Rahman Lawendy, David W. Sanders
Factors Affecting Transfusion Requirement After Hip Fracture: Can We Reduce The Need For Blood?, Sagar J. Desai, Kristi S. Wood, Jackie Marsh, Dianne Bryant, Hussein Abdo, Abdel Rahman Lawendy, David W. Sanders
Bone and Joint Institute
© 2014 Association médicale canadienne. Background: Hip fractures are common injuries that result in blood loss and frequently require the transfusion of blood products. We sought to identify risk factors leading to increased blood transfusion in patients presenting with hip fractures, especially those factors that are modifiable. Methods: We retrospectively reviewed the cases of all patients who had fixation of their hip fractures between October 2005 and February 2010. The need for transfusion was correlated with potential risk factors, including age, sex, preoperative hemoglobin, fracture type, fixation method and more. Results: A total of 835 patients had fixation of their …
Vascular Grafting Strategies In Coronary Intervention, Darryl K. Knight, Elizabeth R. Gillies, Kibret Mequanint
Vascular Grafting Strategies In Coronary Intervention, Darryl K. Knight, Elizabeth R. Gillies, Kibret Mequanint
Bone and Joint Institute
© 2014 Knight, Gillies and Mequanint. With the growing need for coronary revascularizations globally, several strategies to restore blood flow to the heart have been explored. Bypassing the atherosclerotic coronary arteries with autologous grafts, synthetic prostheses, and tissue-engineered vascular grafts continue to be evaluated in search of a readily available vascular graft with clinically acceptable outcomes. The development of such a vascular graft including tissue engineering approaches both in situ and in vitro is herein reviewed, facilitating a detailed comparison on the role of seeded cells in vascular graft patency.
A Randomized Controlled Trial Of Nonoperative Treatment Versus Open Reduction And Internal Fixation For Stable, Displaced, Partial Articular Fractures Of The Radial Head: The Rambo Trial, Wendy Bruinsma, Izaäk Kodde, Robert Jan De Muinck Keizer, Peter Kloen, Anneluuk Lindenhovius, Jos Vroemen, Robert Haverlag, Michel Van Den Bekerom, Hugo Bolhuis, Pieter Bullens, Sven Meylaerts, Peer Van Der Zwaal, Philip Steller, Michiel Hageman, David Ring, Dennis Den Hartog, Eric Hammacher, Graham King, George Athwal, Ken Faber, Darren Drosdowech, Ruby Grewal, J.

Background: The choice between operative or nonoperative treatment is questioned for partial articular fractures of the radial head that have at least 2 millimeters of articular step-off on at least one radiograph (defined as displaced), but less than 2 millimeter of gap between the fragments (defined as stable) and that are not associated with an elbow dislocation, interosseous ligament injury, or other fractures. These kinds of fractures are often classified as Mason type-2 fractures. Retrospective comparative studies suggest that operative treatment might be better than nonoperative treatment, but the long-term results of nonoperative treatment are very good. Most experts agree …

Short-Term Sensory And Cutaneous Vascular Responses To Therapeutic Ultrasound In The Forearms Of Healthy Volunteers, Shaguftha S. Shaik, Joy C. Macdermid, Trevor Birmingham, Ruby Grewal, Baseer Farooq

© 2014 Shaik et al. Background: Therapeutic ultrasound (US) is used for a variety of clinical pathologies and is thought to accelerate tissue repair and help with pain reduction via its thermal and nonthermal effects. The evidence on physiological effects of US on both sensory and vascular functions in humans is incomplete. Hence, the purpose of this study was to determine the short-term impact of two doses of US (3 MHz, 1:4, 0.25 W/cm2, 5 min; 1 MHz, continuous, 0.8 W/cm2, 3 min), on sensory and vascular responses in the healthy forearms. Methods: Twenty healthy subjects were recruited (mean age, …

© 2014 The International Society for Clinical Densitometry. Canadian guidelines recommend either the FRAX or the Canadian Association of Radiologists and Osteoporosis Canada (CAROC) fracture risk assessment tools to report 10-yr fracture risk as low (20%). It is unknown whether one reporting system is more effective in helping family physicians (FPs) identify individuals who require treatment. Individuals ≥50yr old with a distal radius fracture and no previous osteoporosis diagnosis or treatment were recruited. Participants underwent a dual-energy x-ray absorptiometry scan and answered questions about fracture risk factors. Participants' FPs were randomized to receive either a FRAX report or the standard …

© 2014 The Author(s). Computer models capable of predicting elbow flexion and extension range of motion (ROM) limits would be useful for assisting surgeons in improving the outcomes of surgical treatment of patients with elbow contractures. A simple and robust computer-based model was developed that predicts elbow joint ROM using bone geometries calculated from computed tomography image data. The model assumes a hinge-like flexion-extension axis, and that elbow passive ROM limits can be based on terminal bony impingement. The model was validated against experimental results with a cadaveric specimen, and was able to predict the flexion and extension limits of …
