Many resources are expended to ensure a sterile operating room environment. Efforts are made to prevent exposure of patients to personnel and to achieve positive room pressure to keep out airborne contaminants. Foot traffic into and out of the operating room during surgery can undermine these efforts. The authors investigated the number and duration of operating room door openings during hip an...

Infection remains a significant and common complication after joint replacement and there is debate about which contributing factors are important. Few studies have investigated the effect of the operating time on infection. We collected data prospectively from 5277 hip and knee replacements which included the type of procedure, the operating time, the use of drains, the operating theatre, surg...

Abstract: The purpose of this study is to produce scarf joint through explosive welding process (EXW). The scarf weld is a process in which the final bond interface is oblique. With applying the explosive welding technique, this joint can create a metallic bond between similar or dissimilar metals. In this study, chamfered end of aluminum and copper plates were joined explosively and named scar...

Received: 6 March 2006 Revised: 18 December 2007 Accepted: 19 February 2008 Online publication date: 13 November 2008 Abstract Scholars have noted that international investments have the potential to provide firms with real options value under uncertainty. To assess this issue, prior studies have tended to focus primarily on exchange rate volatility. Although multinational firms face other type...

The aim of this retrospective observational study was to assess the potential agreement between independent magnetic resonance imaging (MRI) and arthroscopic findings their respective contributions a final diagnosis in patients with refractory temporomandibular joint disorders. Two dentomaxillofacial radiologists two oral maxillofacial surgeons scored 50 joints. All observers, who were blinded ...

BACKGROUND The tissue origin of low back pain (LBP) or referred lower extremity symptoms (LES) may be identified in about 70% of cases using advanced imaging, discography and facet or sacroiliac joint blocks. These techniques are invasive and availability varies. A clinical examination is non-invasive and widely available but its validity is questioned. Diagnostic studies usually examine single...

OBJECTIVE To evaluate the reliability of a manikin format, patient-reported joint count in juvenile idiopathic arthritis (JIA), and to detect changes in agreement at a second visit. METHODS Patients with JIA aged 12-21 were asked to mark joints with active arthritis on a manikin before their regular clinic visit. The physician then performed a joint count without having seen the patient's ass...

A large and clearly visible operating area is essential for successful arthroscopic surgery of the temporomandibular joint. The keys to a successful operation are the safe and accurate positioning of a large scope and multiple cannulations, overcoming blind areas. We developed some instruments to resolve these problems; i.e., scopes with a large diameter for high resolution, a triangulation ins...
