Abstract
Operative therapy of intraarticular fractures of the calcaneus is an established surgical standard. The aim is an accurate reduction of the fracture with reconstruction of Boehler’s angle, length, axis and subtalar joint surface. Intraoperative 3D-fluoroscopy with the Siremobil Iso-C 3D® mobile C-arm system is a valuable assistant for accurate reconstruction of these anatomical structures. Remaining incongruities can be recognized and corrected intraoperatively. The achieved reduction can be fixed by the advantages of an internal fixator (locked-screw plate interface). In the period of October 2002 until April 2007 we operated 136 patients with intraarticular fractures of the calcaneus by means of anatomical reduction, and internal plate fixator under intraoperative control of 3D-fluoroscopy. All patients were supplied with an orthesis after the operation which allowed weight bearing of 10 kg for 12 weeks for the patients operated between October 2002 and October 2004 (Group A). Transient local osteoporosis was observed in all X-Rays at follow-up after an average of 8,6 months. Therefore we changed our postoperative treatment plan for the patients operated between November 2004 and April 2007 (Group B). Weight bearing started with 20 KG after 6 weeks, was increased to 40 KG after 8 weeks and full weight bearing was allowed after 10 weeks for these patients. In no case a secondary dislocation of the fracture was seen. No bone graft was used. At follow up the average American Foot and Ankle Society Score (AOFAS) were 81 for Group_A, compared to 84 for Group B, treated with earlier weight bearing. Autologous bone graft was not necessary even if weight bearing was started after a period of six weeks postoperatively. The combination of 3D-fluoroscopy with locked internal fixation showed promising results. If the rate of patients developing subtalar arthrosis will decrease by this management will have to be shown in long term follow up.

Abstract
Cardiovascular risk factor modification to prevent progression of coronary heart disease is important for patients following percutaneous coronary intervention. The aims of this study were to assess patient's awareness of modifiable cardiac risk factors and examine if patients with modifiable risk factors were more likely to identify these risk as amenable to change. Awareness of risk factors was measured using the Indiana Cardiac Rehabilitation Knowledge Questionnaire in a cohort of prospective, consecutive participants post percutaneous coronary intervention. Completed questionnaires were received from 75% of the participants. The majority were able to identify high cholesterol (87%), smoking (83%) and hypertension (82%) as modifiable risk factors. Less than half (46%) of the respondents identified diabetes as a modifiable risk factor. Only a third of participants recognized all six modifiable risk factors. A large proportion of patients who were smokers, or who had high cholesterol or hypertension, identified these as risk factors. A third of people with documented diabetes did not recognize this condition as a risk factor for heart disease. The findings have important implications for nursing practice in terms of directing educational efforts for the modification of risk factors for coronary heart disease.

Abstract
PURPOSE The purpose of this study was to describe the trajectory of cardiac patient's perceptions of health-related quality of life (HRQoL) during a 24-month period in a community-based population. METHODS After obtaining informed consent, a self-administered questionnaire was mailed to participants. Using the MacNew questionnaire, which assesses the emotional, physical, social, and global domains, HRQoL outcomes were assessed. RESULTS Completed questionnaires were received from 202 participants (75%). Improvements in the emotional, physical, social, and global HRQoL scores were observed until 15 to 17 months after the index percutaneous coronary intervention, after which a decline was observed. However, the scores in all HRQoL domains remained high when compared with the scores at 12 months. No clinical or sociodemographic predictors for HRQoL were identified. CONCLUSIONS The information obtained from this study will enable clinicians to further understand the process of recovery and adjustment of patients after percutaneous coronary intervention and the development of tailored strategies for patient management.

Abstract
BACKGROUND In spite of the benefit in participating in cardiac rehabilitation (CR) programs, low participation rates are well documented. Participation rates are potentially lower in people who have undergone percutaneous coronary interventions (PCI). Assessment of the barriers to CR participation in PCI patients could provide vital information for the development of alternate strategies for coronary risk factor modification. AIM The aim of this study was to develop and evaluate the psychometric properties of a scale to assess obstacles to cardiac rehabilitation enrolment in patients following PCI. METHODS Item generation for the 15 items of this scale was based on a comprehensive review of the literature and data collected from telephone interviews of CR coordinators related to cardiac rehabilitation enrolment obstacles (CREO). Content validity of the scale was undertaken using a reference group comprising of clinicians and patients. Construct validity was undertaken using a factor analysis. Data for the CREO scale was collected from December 2004 to March 2005 from 114 PCI patients recruited from a cardiology database in a Sydney metropolitan hospital. RESULTS Factor analysis revealed a two-factor structure: patient-related obstacles and health service-related obstacles, which accounted for 58% of cumulative explained variance. The scale showed good internal consistency (Cronbach's alpha=0.89) and satisfactory divergent validity. CONCLUSION This scale can be used as a useful tool for the early identification of patients who would not normally enrol into CR and offer them alternate strategies for health-related lifestyle modification.

Abstract
BACKGROUND Percutaneous coronary intervention (PCI) is a widely performed revascularization technique for coronary heart disease; however, there is limited research investigating the risk factor status of patients 1 year after the procedure. OBJECTIVE This cross-sectional study was conducted to investigate the self-reported risk factor status by patients who had undergone a PCI at a major teaching hospital in Sydney, Australia. SUBJECTS : Two hundred seventy participants who underwent PCI between April 2003 and March 2004 and who met the inclusion criteria were followed up 1 year after the PCI. METHODS After obtaining informed consent, a follow-up self-administered questionnaire was mailed to participants. Information was collected relating to the following coronary risk factors: smoking, and physical activity status, blood pressure and cholesterol levels, body mass index, depression, anxiety, and stress levels. RESULTS Two hundred two participants (75%) returned a completed questionnaire. Approximately one third of participants had at least two modifiable risk factors. The most common cardiovascular risk factors identified were physical inactivity, increased body mass index, high blood pressure, and high cholesterol. Approximately half the women (46%) and a quarter of the men had at least two modifiable risk factors. Only a minority (11%) of the participants continued to smoke at 1-year follow up. Participating in physical activity for a total time of 150 minutes or more per week was reported by only 42% of the participants. Depression and anxiety were present in 25% and stress in 17% of the participants. A third of the participants (n = 64) erroneously believed that they had no heart problems. CONCLUSIONS The findings reveal inadequate management of modifiable risk factors among post-PCI participants 12 to 18 months after revascularization, which highlights a need for tailored secondary prevention interventions to address factors contributing to cardiovascular risk. The evidence obtained from this study will inform the development of an intervention to address cardiovascular risk factor modification.

Abstract
PURPOSE To test whether an electromagnetic guidance system such as CathTrack would allow long-term central venous access devices to be reliably placed at a decreased cost and without radiation exposure to patients and staff. The following study was undertaken to verify accuracy of the CathTrack system for catheter placement and to develop guidelines for its use. METHODS Twenty-nine consecutive patients were prospectively enrolled in the study and taken to the operating room for implantation of a permanent central venous access port. By protocol, the CathTrack system was used to guide initial catheter positioning using the center of the third intercostal space along the right sternal border as the desired external target. Fluoroscopy was then used to visualize tip position and relocate the catheter tip to the exact position desired by the surgeon. RESULTS Catheter placement using the CathTrack system was successfully accomplished in 27 out of 29 patients. In two instances CathTrack was abandoned and fluoroscopy utilized because of difficulty in threading the initial guidewire into the superior vena cava. CONCLUSION The CathTrack electromagnetic locator system can be used to reliably position catheters for the establishment of long-term central venous access. Decreased cost and elimination of radiation exposure are distinct advantages of this system over fluoroscopy.

Abstract
Using hexapod robot kinematics, an external fixator adjustable in all six spatial degrees of freedom was developed. As usual with a robot system, bone movements can be accomplished with high precision. Contrary to conventional external fixators any three-dimensional movement is realisable without giving up stability or the necessity to change parts of the construction during the treatment. At first a manually controlled fixator with appropriate software was developed. Then electromotor elements were added, resulting in a "fracture reduction robot" and a fixator featuring load measurement capabilities was built. Finally the concept was extended into an "intelligent fixator" which will accomplish automatically controlled fracture and deformity treatment in the future.
