ABSTRACT
IMPORTANCE: Supervised exercise is recommended as a first-line treatment for intermittent claudication. Combination therapy of endovascular revascularization plus supervised exercise may be more promising but few data comparing the 2 therapies are available. OBJECTIVE: To assess the effectiveness of endovascular revascularization plus supervised exercise for intermittent claudication compared with supervised exercise only. DESIGN, SETTING, AND PARTICIPANTS: Randomized clinical trial of 212 patients allocated to either endovascular revascularization plus supervised exercise or supervised exercise only. Data were collected between May 17, 2010, and February 16, 2013, in the Netherlands at 10 sites. Patients were followed up for 12 months and the data were analyzed according to the intention-to-treat principle. INTERVENTIONS: A combination of endovascular revascularization (selective stenting) plus supervised exercise (n = 106) or supervised exercise only (n = 106). MAIN OUTCOMES AND MEASURES: The primary end point was the difference in maximum treadmill walking distance at 12 months between the groups. Secondary end points included treadmill pain-free walking distance, vascular quality of life (VascuQol) score (1 [worst outcome] to 7 [best outcome]), and 36-item Short-Form Health Survey (SF-36) domain scores for physical functioning, physical role functioning, bodily pain, and general health perceptions (0 [severe limitation] to 100 [no limitation]). RESULTS: Endovascular revascularization plus supervised exercise (combination therapy) was associated with significantly greater improvement in maximum walking distance (from 264 m to 1501 m for an improvement of 1237 m) compared with the supervised exercise only group (from 285 m to 1240 m for improvement of 955 m) (mean difference between groups, 282 m; 99% CI, 60-505 m) and in pain-free walking distance (from 117 m to 1237 m for an improvement of 1120 m vs from 135 m to 847 m for improvement of 712 m, respectively) (mean difference, 408 m; 99% CI, 195-622 m). Similarly, the combination therapy group demonstrated significantly greater improvement in the disease-specific VascuQol score (1.34 [99% CI, 1.04-1.64] in the combination therapy group vs 0.73 [99% CI, 0.43-1.03] in the exercise group; mean difference, 0.62 [99% CI, 0.20-1.03]) and in the score for the SF-36 physical functioning (22.4 [99% CI, 16.3-28.5] vs 12.6 [99% CI, 6.3-18.9], respectively; mean difference, 9.8 [99% CI, 1.4-18.2]). No significant differences were found for the SF-36 domains of physical role functioning, bodily pain, and general health perceptions. CONCLUSIONS AND RELEVANCE: Among patients with intermittent claudication after 1 year of follow-up, a combination therapy of endovascular revascularization followed by supervised exercise resulted in significantly greater improvement in walking distances and health-related quality-of-life scores compared with supervised exercise only.

BACKGROUND: The prevalence of osteoporosis in the Netherlands is 52 per 1,000 men and 166 per 1,000 women (age >55 years). Previous results of an osteoporosis screening program showed that 55%, 41%, and 37.1% had osteoporosis. This study aims to evaluate the incidence of osteoporosis after low-energy fractures and to describe the care program for osteoporosis screening. The second endpoint was to investigate the incidence of risk factors in the whole study population and a subgroup analysis from the three major groups with osteoporotic fractures. METHODS: All female and male patients older than 50 years with a low-energy fracture were included for the osteoporosis screening program. Patients with a fracture of the vertebrae were also included if the age was less than 50 years. All patients underwent a bone mineral density measurement by means of dual-energy X-ray film absorptiometry. All obtained data were registered by a nurse specialist in osteoporosis, in a computerized database. RESULTS: The incidence of osteoporosis in patients with low-energy fractures is high, 46.4%. At the time of fracture presentation, there were 33.2% of the patients with a low body weight (<67 kg), almost all osteoporotic patients (96%) had a low-energy fracture occurred after their 50th year. In patients diagnosed with osteoporosis, the hip fracture is the most common fracture site (34%), followed by the humerus (20.1%). CONCLUSIONS: In conclusion, a screening program for osteoporosis is necessary and should be a tool in the armamentarium of every traumatology department.
