Self-guided brisk walking training with or without poles: a randomized-controlled trial in middle-aged women.

Walking with poles (Nordic walking, NW) has become popular. We compared training responses of brisk walking (W) or NW on cardiorespiratory and neuromuscular fitness. We randomized 121 non-obese sedentary women (aged 50-60) to an NW or W group (NWG, WG), to train 40 min four times weekly for 13 weeks. Intensity was based on subjective perception of exertion. Cardiorespiratory performance was assessed in four levels corresponding to 50%, 65%, 80% and 100% of peak VO(2). Fifty-four NWG and 53 WG subjects completed the study. The mean intensity was about 50% of heart rate (HR) reserve. The baseline peak VO(2) was 25.8 (SD 3.9) mL/min/kg. Both groups improved peak VO(2) similarly (NWG 2.5 mL/min/kg, 95% confidence interval (CI) 1.9-3.3; WG 2.6, CI 1.9-3.3). In the submaximal stages while walking with or without poles, HR and lactate decreased after training in both groups, but the changes were not statistically significantly different between the groups. Of the neuromuscular tests after training, the only significant difference between the groups was in the leg strength in the one-leg squat, favoring WG. In conclusion, both training modes improved similarly health-enhancing physical fitness, and they were feasible and safe.

Knee injuries in leisure-time physical activities: a prospective one-year follow-up of a Finnish population cohort.

This prospective one-year follow-up study compared the risks of knee injuries in various commuting and lifestyle activities as well as in recreational and competitive sports in a 15 to 74-year-old Finnish population cohort. A cohort of 3657 persons was randomly selected from the nationwide population register of Finland. Ninety-two percent of them accepted to participate (n = 3363). The subjects were interviewed by telephone three times during the one-year follow-up. The recorded data included all physical activities that lasted 15 minutes or more, and all injuries that were sustained during these activities. Fifteen percent (n = 321) of all reported injuries affected the knee. The individual risk of knee injury per 1000 exposure hours was low in commuting activities (cycling, walking), 0.06 (95 % CI 0.04 to 0.09) and in lifestyle activities (gardening, hunting, fishing, home repair etc.), 0.04 (0.03 - 0.06). In recreational and competitive sports, the knee injury risk was almost ten times higher, 0.44 (0.39 - 0.50). For commuting activities (p = 0.046) and for recreational and competitive sports (p < 0.001), there was a decreasing injury rate with age. In lifestyle activities (p = 0.038), in turn, there was an increasing trend of injuries with aging. In commuting activities (hazard ratio, HR 5.99, 95 % CI 1.40 to 25.6), the risk of knee injury was significantly higher in women than in men. In conclusion, the knee injury risk per exposure hours is almost ten times lower in commuting and lifestyle activities compared to recreational and competitive sports. The knee injury risk is especially high in the age group of 15 to 25 years, especially in various team sports and ball games. At population level, however, widely practiced low-to-moderate intensity activities with relatively low injury risk per exposure hours produce a large absolute number of knee injuries.

Exercise-induced bronchospasm among healthy elite cross country skiers and non-athletic students.

Regular exercise in cold, dry air is believed to be a predisposing factor for exercise-induced bronchospasm (EIB). The aim of this study was to compare the occurrence of EIB among previously healthy elite cross country skiers and their non-athletic control subjects. Twenty healthy elite cross country skiers and 18 non-asthmatic controls were challenged by a standardized free exercise test. Thereafter, subjects' respiratory function was followed by flow-volume spirometry up to 30 min. EIB was defined in the post-exercise spirometry as at least one of the following: a >or=10% decrease in forced expiratory volume in 1 s (FEV1), a >or=20% decrease in mean maximal expiratory flow (MMEF) or a >or=25% decrease in peak expiratory flow rate (PEF). EIB was found in two skiers and one control according to FEV1, for seven skiers and two controls according to MMEF. Two skiers and one control had exercise-induced asthma (EIA) according to both parameters. The largest decrease in PEF was 13%, that did not result in additional diagnoses. All nine of the subjects with a positive test result reported asthma-like symptoms (dyspnea, cough or increased mucus excretion) after the exercise challenge. Accordingly, seven previously healthy skiers (35%) and two controls (11%) were diagnosed as having EIB. In addition, three skiers of the original cohort were excluded because of an earlier asthma diagnosis, making the total asthma prevalence 10/23 (42%) among the elite skiers. It was concluded that EIB is more common in elite cross country skiers than in non-athletic controls. The bronchoconstriction induced by exercise is usually mild or moderate, and flow-volume spirometry with sensitive flow parameters is needed for it to be diagnosed. Even a mild asthma decreases minute ventilation and maximal performance of winter sport athletes. Therefore, skiers with long-term respiratory symptoms or decreased performance should be studied for EIA and treated adequately.

Hospital-treated minimal-trauma rib fractures in elderly Finns: long-term trends and projections for the future.

We determined the current trends in the number and incidence of hospital-treated minimal-trauma rib fractures (low- to moderate-energy traumas typically caused by a fall from standing height or less) in Finnish elderly people by collecting from the National Hospital Discharge Register all patients 60 years of age or more who were admitted to hospitals in 1970-2001 for primary treatment of such fractures. The number and incidence (per 100,000 persons) of these fractures clearly increased from 268 (number) and 41 (incidence) in 1970 to 737 and 70 in 2001, while in younger patients (aged 20-49 years) the trend was decreasing, the corresponding numbers being 194 and 10 in 1970, and 153 and 7 in 2001. In the elderly Finns, also the age-adjusted incidence of these hospital-admitted rib fractures showed an increase, from 37 (1970) to 51 (2001) in women, and from 63 to 77 in men. In women aged 80 years and over, the age-specific incidence of fracture increased from 88 to 186, while in the other age groups only slight secular changes were found. If the above-described trends continue, the number of elderly Finns admitted to a hospital due to a rib fracture will more than double in next three decades.

Active living and injury risk.

The purpose of this study was to get reliable insight into injury risk in various commuting and lifestyle activities, as well as recreational and competitive sports. A cohort of 3 657 persons was randomly selected from the 15- to 74-year-old Finnish population. Ninety-two percent (n = 3 363) of the subjects accepted to participate the one-year follow-up, record all their physical activities that lasted 15 min or more, and register all acute and overuse injuries that occurred during these activities. To collect the information, the study subjects were interviewed by phone by the trained personnel of the Statistics Finland three times in four-month intervals. The individual injury risk per exposure time was relatively low, ranging from 0.19 to 1.5 per 1 000 hours of participation, in commuting and lifestyle activities including walking and cycling to work, gardening, home repair, hunting and fishing, and, in sports such as golf, dancing, swimming, walking, and rowing. The risk was clearly higher in squash, orienteering, and contact and team sports, such as judo, wrestling, karate, rinkball, floorball, basketball, soccer, ice hockey, volleyball, and Finnish baseball ranging from 6.6 to 18.3 per 1 000 hours of participation. However, the highest absolute number of injuries occurred in low-risk activities, such as gardening, walking, home-repair, and cycling, because they are performed so often. In conclusion, individual injury risk per exposure hours is relatively low in commuting and lifestyle activities compared to many recreational and competitive sports. However, at a population level, these low-to-moderate intensity activities are widely practised producing a rather high absolute number of injuries, and thus, preventive efforts are needed in these activities, too.

Basic science and clinical studies coincide: active treatment approach is needed after a sports injury.

The basic response to injury at the tissue level is well known and consists of acute inflammatory phase, proliferative phase, and maturation and remodeling phase. Knowing these phases, the treatment and rehabilitation program of athletes' acute musculoskeletal injuries should use a short period of immobilization followed by controlled and progressive mobilization. Both experimental and clinical trials have given systematic and convincing evidence that this program is superior to immobilization - a good example where basic science and clinical studies do coincide - and therefore active approach is needed in the treatment of these injuries.

[Pathophysiology of overuse tendon injury].

Overuse tendon injury is one of the most common injuries in sports. The etiology as well as the pathophysiological mechanisms leading to tendinopathy are of crucial medical importance. At the moment intrinsic and extrinsic factors are assumed as mechanisms of overuse tendon injury. Except for the acute, extrinsic trauma, the chronic overuse tendon injury is a multifactorial process. There are many other factors, such as local hypoxia, less of nutrition, impaired metabolism and local inflammatory that may also contribute to the development of tissue damage. The exact interaction of these factors cannot be explained entirely at the moment. Further studies will be necessary in order to get more information.

Increasing number and incidence of low-trauma ankle fractures in elderly people: Finnish statistics during 1970-2000 and projections for the future.

To increase knowledge about recent trends in the number and incidence of various low-trauma injuries among elderly people, we selected, from the National Hospital Discharge Register, all patients > or =60 years of age who were admitted to hospitals in Finland (5 million population) for primary treatment of a first low-trauma ankle fracture during 1970-2000. In each year of the study, the age-adjusted and age-specific incidence of fracture was expressed as the number of patients per 100,000 persons. The predicted numbers and incidence rates of fractures until the year 2030 were calculated using a regression model. For the study period, the number and incidence of low-trauma ankle fractures in Finnish persons > or =60 years of age rose substantially: the total number of fractures increased from 369 in 1970 to 1545 in 2000, a 319% increase, and the crude incidence increased from 57 to 150, a 163% increase. The age-adjusted incidence of these fractures also rose in both women (from 66 in 1970 to 174 in 2000, a 164% increase) and men (from 38 in 1970 to 114 in 2000, a 200% increase). The regression model indicates that, if this trend continues, there will be about three times more low-trauma ankle fractures in Finland in the year 2030 than there was in 2000. In conclusion, the number of low-trauma ankle fractures in elderly Finns is rising rapidly at a rate that cannot be explained simply by demographic changes and, therefore, potentially effective preventive measures, such as prevention of slippings, trippings, and falls in elderly people, and use of ankle supports, should be urgently studied.

Epidemiology of adulthood injuries: a quickly changing injury profile in Finland.

Although developed societies have undergone many profound changes during recent decades, including urbanization, increased traffic and aging of the populations, epidemiologic information on secular trends in profiles of injuries is limited. We investigated such trends in Finland by selecting from the National Hospital Discharge Register all Finns aged 15 years or more who required hospital treatment because of an unintentional injury during 1971-1995. The injury incidences were expressed as the number of patients per 100,000 individuals per year. In Finnish men, road traffic accidents and falls, the two leading causes of injury, produced equal numbers of injuries in 1971 (4935 and 4957), but thereafter the role of the traffic accidents gradually decreased (3512 injuries with unadjusted and age-adjusted incidences of 177 and 183 in 1995) and that of falls clearly increased (13,218 injuries with unadjusted and age-adjusted incidences of 664 and 635 in 1995). Changes in the other injury categories of men were less drastic. In Finnish women, falling was the most common cause of injury in 1971 (5051 injuries), after which its role increased sharply, to 17,250 injuries in 1995 (unadjusted and age-adjusted incidences of 804 and 698, respectively). In 1971, road traffic produced 2369 injuries in women, after which this number somewhat decreased (2160 injuries with unadjusted and age-adjusted incidences of 101 and 101 in 1995). The role of all the other injury categories was small in Finnish women during 1971-1995. We conclude that a quick change in the overall profile of injuries occurred in Finland in 1971-1995, a change in which falls replaced road traffic accidents as the major cause of a serious injury. This epidemiologic change will give a new challenge for injury prevention in the new millennium.

Continuously rising problem of osteoporotic knee fractures in elderly women: nationwide statistics in Finland in 1970-1999 and predictions until the year 2030.

We assessed the current trends in the number and incidence of osteoporotic knee fractures in Finland by collecting data from the National Hospital Discharge Register for all patients > or =60 years of age who were admitted to Finnish hospitals in 1970-1999 for primary treatment of such fractures. The knee fracture was defined "osteoporotic" if it was caused by a low-energy trauma only; that is, a fall from standing height or less. We also predicted fracture development until the year 2030 by a regression model, which took into account the predicted changes in the fracture incidences and population at risk. The number and incidence (per 100,000 persons) of osteoporotic knee fractures in Finnish women aged > or =60 years clearly rose during the study period, from 218 (number) and 55 (incidence) in 1970 to 685 and 113 in 1999. Even after age adjustment, the incidence of women's fractures showed a clear increase, from 59 in 1970 to 105 in 1999. If this trend continues, there will be about 2.5 times more osteoporotic knee fractures in Finnish women in the year 2030 than there were in 1999. In Finnish men aged > or =60 years, the annual number of fractures and its changes were clearly smaller (77 in 1970 vs. 138 in 1999), and the fracture incidence did not show consistent trend changes over time (30 in 1970 vs. 34 in 1999). We conclude that in elderly Finnish women the number of osteoporotic knee fractures shows a rise with a rate that cannot be explained merely by demographic changes and, therefore, vigorous preventive measures are needed to control this development.

Sports injuries in floorball: a prospective one-year follow-up study.

Two hundred and ninety-five licensed floorball players from Finnish premier to fifth division were observed prospectively for one season to study the incidence, nature, causes and severity of floorball injuries. During the study period, 100 out of the 295 (34 %) players sustained 120 injuries. Thirty-seven percent (73/199) of the male players and 28 % (27/96) of the females suffered from an injury. The injury rate was 1.0 per 1000 practice hours for both sexes. The injury rates per 1000 game hours were 23.7 for men and 15.9 for women. One hundred injuries (83 %) were acute and the remaining 20 (17 %) were overuse injuries. Sprain was the most common type of injury in men while overuse injuries were the most frequent injury type in women. The lower extremity was involved in 62 %, spine or trunk in 19 % and upper extremity in 10 % of the injuries. The most commonly injured sites were the knee and ankle (22 % and 20 % of all injuries), followed by head and neck (8 %). In both sexes the majority of injuries were minor, level II, injuries. Ten of the knee injuries (38 %) were serious, level IV injuries, of which seven were ACL ruptures. In conclusion, the individual risk of injury in floorball is relatively low in game practice while rather high during the game itself. Before initiation of clinical trials on prevention of floorball injuries, an exact knowledge of the risk factors and mechanisms of floorball injuries are needed.

Is it possible to prevent sports injuries? Review of controlled clinical trials and recommendations for future work.

Sports injuries are one of the most common injuries in modern western societies. Treating sports injuries is often difficult, expensive and time consuming, and thus, preventive strategies and activities are justified on medical as well as economic grounds. A successful injury surveillance and prevention requires valid pre- and post-intervention data on the extent of the problem. The aetiology, risk factors and exact mechanisms of injuries need to be identified before initiating a measure or programme for preventing sports injuries, and measurement of the outcome (injury) must include a standardised definition of the injury and its severity, as well as a systematic method of collecting the information. Valid and reliable measurement of the exposure includes exact information about the population at risk and exposure time. The true efficacy of a preventive measure or programme can be best evaluated through a well-planned randomised trial. Until now, 16 randomised, controlled trials (RCT) have been published on prevention of sports injuries. According to these RCT, the general injury rate can be reduced by a multifactorial injury prevention programme in soccer (relative risk 0.25, p < 0.001, in the intervention group), or by ankle disk training, combined with a thorough warm-up, in European team handball [odds ratio 0.17; 95% confidence interval (CI) 0.09 to 0.32, p < 0.01]. Ankle sprains can be prevented by ankle supports (i.e. semirigid orthoses or air-cast braces) in high-risk sporting activities, such as soccer and basketball (Peto odds ratio 0.49; 95% CI 0.37 to 0.66), and stress fractures of the lower limb by the use of shock-absorbing insoles in footwear (Peto odds ratio 0.47; 95% CI 0.30 to 0.76). In future studies, it is extremely important for researches to seek consultation with epidemiologists and statisticians to be certain that the study hypothesis is appropriate and that the methodology can lead to reliable and valid information. Further well-designed randomised studies are needed on preventive actions and devices that are in common use, such as preseason medical screenings, warming up, proprioceptive training, stretching, muscle strengthening, taping, protective equipment, rehabilitation programmes and education interventions (such as increasing general injury awareness among a team). The effect of a planned rule change on the injury risk in a particular sport could be tested via a RCT before execution of the change. The most urgent needs are in commonly practised or high-risk sports, such as soccer, American football, rugby, ice hockey, European team handball, karate, floorball, basketball, downhill skiing and motor sports.

Prevention of hip fracture in elderly people with use of a hip protector.

BACKGROUND: Hip fractures are common in frail elderly adults worldwide. We investigated the effect of an anatomically designed external hip protector on the risk of these age-related fractures. METHODS: We randomly assigned 1801 ambulatory but frail elderly adults (1409 women and 392 men; mean age, 82 years), in a 1:2 ratio, either to a group that wore a hip protector or to a control group. Fractures of the hip and all other fractures were recorded until the end of the first full month after 62 hip fractures had occurred in the control group. The risk of fracture in the two groups was compared, and in the hip-protector group the risk of fracture was also analyzed according to whether the protector had been in use at the time of a fall. RESULTS: During follow-up, 13 subjects in the hip-protector group had a hip fracture, as compared with 67 subjects in the control group. The respective rates of hip fracture were 21.3 and 46.0 per 1000 person-years (relative hazard in the hip-protector group, 0.4; 95 percent confidence interval, 0.2 to 0.8; P=0.008). The risk of pelvic fracture was slightly but not significantly lower in the hip-protector group than in the control group (2 subjects and 12 subjects, respectively, had pelvic fracture) (relative hazard, 0.4; 95 percent confidence interval, 0.1 to 1.8; P > or = 0.05). The risk of other fractures was similar in the two groups. In the hip-protector group, four subjects had a hip fracture (among 1034 falls) while wearing the protector, and nine subjects had a hip fracture (among 370 falls) while not wearing the protector (relative hazard, 0.2; 95 percent confidence interval, 0.05 to 0.5; P=0.002). CONCLUSIONS: The risk of hip fracture can be reduced in frail elderly adults by the use of an anatomically designed external hip protector.

A controlled trial of the health benefits of regular walking on a golf course.

PURPOSE: To study the effects of regular walking during a golf game on various health and fitness indicators in middle-aged men. METHODS: Study subjects were 55 healthy male golfers aged 48 to 64 years who had been sedentary during the 7 months before the study, and 55 age-matched, similarly sedentary controls. During the 20-week study, those in the intervention group were encouraged to play golf two to three times a week; the controls were not. Measurements of body composition, cardiorespiratory performance, motor and musculoskeletal fitness, blood pressure, and serum lipid, glucose, and insulin levels were obtained at baseline and after the 20-week study. RESULTS: Walking during a golf game was a practical and safe form of physical activity with high adherence. It significantly increased aerobic performance and trunk muscle endurance, with a net difference (pretraining to posttraining change between the golfers and controls) of 36 seconds (95% confidence interval [CI]: 19 to 53 seconds, P < 0.001) for treadmill walking time and 13 seconds (95% CI: 2 to 24 seconds, P = 0.02) for static back extension. In addition, regular walking favorably affected body composition, including reductions in weight of 1.4 kg (95% CI: 0.6 to 2.1 kg, P < 0.001), in waist circumference of 2.2 cm (95% CI: 1.0 to 3.3 cm, P < 0.001), and in abdominal skin fold thickness of 2.2 cm (95% CI: 0.9 to 3.4 cm, P = 0.001). Golfers also had significantly greater increases in serum high-density lipoprotein (HDL) cholesterol levels and in the ratio of HDL cholesterol to total cholesterol. CONCLUSIONS: Regular walking had many positive effects on the health and fitness of sedentary middle-aged men. Walking during a golf game is characterized by high adherence and low risk of injury and is therefore a good form of health-enhancing physical activity.

Continuously increasing number and incidence of fall-induced, fracture-associated, spinal cord injuries in elderly persons.

BACKGROUND: Although osteoporosis, falls, and fractures among older adults are said to be a continuously increasing public health problem, reliable epidemiological information on their secular trends is very limited. OBJECTIVE: To determine the current trend in the number and incidence of fall-induced, fracture-associated, spinal cord injuries in a typical white population (Finland, a country with about 5 million inhabitants). METHODS: All Finns aged 50 years or older who were admitted to hospitals from January 1, 1970, through December 31, 1995, for primary treatment of an acute fall-induced, fracture-associated, spinal cord injury were selected from the National Hospital Discharge Register. Similar patients aged 20 through 39 years served as a reference group. In each year of the study, the number and the age-specific and age-adjusted incidences of injuries were expressed as the number of patients per 100,000 persons. RESULTS: The total number of fall-induced, fracture-associated, spinal cord injuries of Finnish older adults increased considerably during the study period, from 60 in 1970 to 419 in 1995 (an average increase of 24% annually). The corresponding injury incidence was 5 in 1970 and 27 in 1995. The age-adjusted incidence of these injuries also increased from 1970 to 1995: in women, from 5 to 29, and in men, from 7 to 17 (relative increases were 480% and 143%, respectively). In the reference group, no trend changes by time were observed. CONCLUSIONS: In Finnish persons aged 50 years or older, the number of fall-induced, fracture-associated, spinal cord injuries shows a rise with a rate that cannot be explained merely by demographic changes. The finding shows an increasing influence of osteoporosis and falls on health and well-being of our older adults, and therefore, vigorous preventive measures are needed to control this development.

The injury mechanisms of osteoporotic upper extremity fractures among older adults: a controlled study of 287 consecutive patients and their 108 controls.

The risk factors for falls in older adults are well known but knowledge on the direct injury mechanisms that result in various osteoporotic fractures has been very sparse. The purpose of this study was therefore to clarify the injury mechanisms of osteoporotic upper extremity fractures of older adults and to compare these mechanisms with those of the control fallers, and in this way to obtain reliable insight into the etiology and pathogenesis of upper extremity fractures and thus to enable fracture prevention. One hundred and twelve patients with a fresh fracture of the proximal humerus, 65 patients with an elbow fracture, 110 patients with a wrist fracture and 108 controls (no fracture, or a fracture other than the case fracture) were interviewed and examined between September 1995 and December 1997. The inclusion criteria of the subjects were that the patient was 50 years of age or older at the time of the accident, and that the fracture/injury had occurred as a result of low-energy trauma (typically a fall from standing height or less) within a week before the interview and examination. In 97% of patients with a proximal humerus or elbow fracture, and in all patients (100%) with a wrist fracture, the fracture was a result of a fall. In the control group this figure was 93%. In a polychotomous logistic regression analysis the intergroup differences in the fall directions (adjusted by gender, age and functional capacity) were statistically highly significant (chi 2 = 43.6, d.f. = 15, p < 0.001). Most of the patients with a proximal humerus fracture or elbow fracture reported that they had fallen 'obliquely forward' (43% and 38%) or 'to the side' (29% and 26%), whereas in the wrist fracture group the main fall direction was also 'obliquely forward' (34%) but the other fall directions (i.e., 'forward', 'to the side', 'obliquely backward' and 'backward') were quite equally represented (13-19%). The odds ratio (OR) for an obliquely forward fall resulting in a proximal humerus fracture was 3.5 [95% confidence interval (CI) 1.4-9.2), as compared with the fall directions of the controls and the 'obliquely backward' fall direction. In a logistic regression analysis the patients with a wrist fracture managed to break their fall (e.g., with an outstretched arm) more frequently than the patients in the other groups (OR 3.9; 95% CI 2.0-7.3). The patients with a proximal humerus fracture, in turn, managed to break their fall less frequently than the controls (OR 0.33; 95% CI 0.14-0.80). The same was true of the patients with an elbow fracture, although the difference was not significant (OR 0.49%; 95% CI 0.19-1.3). As objective evidence for a direct fall-induced impact on the fracture site, 68% of patients with a proximal humerus fracture revealed a fresh subcutaneous hematoma on the shoulder/upper arm, while such a hematoma was rare in the controls (2%) (p < 0.001). Correspondingly, 62% of patients with an elbow fracture showed a similar hematoma on the elbow area, while this was seen in none of the controls (p < 0.001). In patients with a wrist fracture a hand/wrist hematoma was seen in 58% of the victims, as compared with 18% of the controls (p < 0.001). The study shows that the most typical osteoporotic upper extremity fractures of older adults have their specific injury mechanisms. A great majority of these fractures occur as a result of a fall and a subsequent direct impact of the fractured site. Effective fracture prevention could be achieved by minimizing the obvious risk factors of falling and reducing the fall-induced impact force with injury site protection.

Epidemiology of osteoporotic pelvic fractures in elderly people in Finland: sharp increase in 1970-1997 and alarming projections for the new millennium.

The purpose of our epidemiologic study was to determine the current trend in the number and incidence of osteoporotic pelvic fractures in Finland, a country with a Caucasian population of 5 million. Thus, all Finns 60 years of age or older who were admitted to hospitals in 1970-1997 for primary treatment of a first osteoporotic pelvic fracture were selected from The National Hospital Discharge Register. In each year of the study, the number and the age-specific and age-adjusted incidences of fractures were expressed as the number of. patients per 100,000 individuals. The total number of osteoporotic pelvic fractures increased considerably in Finland during the study period, from 128 in 1970 to 913 in 1997, an average increase of 23% a year. The corresponding fracture incidence (per 100,000 persons 60 years of age or older) was 20 in 1970 and 92 in 1997. The mean age of the patients also increased, from 74 years (1970) to 80 years (1997). Despite this, the age-adjusted incidence of osteoporotic pelvic fractures also showed a steady increase from 1970 to 1997: in women, from 31 to 103, and in men, from 13 to 38 (relative increases were 232% and 192%, respectively). If this trend continues, the current number of osteoporotic pelvic fractures in this country (about 900 fractures per year) may treble by the year 2030 (about 2,700 fractures per year). We conclude that the number of osteoporotic pelvic fractures in elderly Finns is increasing at a rate that cannot be explained simply by demographic changes and therefore effective preventive measures should be urgently initiated to control the increasing burden of these age-related fractures.
