Total hip replacement: its influence on spontaneous recreation exercise habits.

The effect of total hip replacement (McKee-Farrar or Brunswik prosthesis) on recreational exercise habits was evaluated with a retrospective interview of 539 patients operated on at the orthopaedic Hospital of the Invalid Foundation, Helsinki, Finland. The mean age of the patients was 63.8 years and the mean follow-up time 4.2 years. The proportion of those who engaged in regular walking increased from 2 to 55%, in cycling from 7 to 29%, in swimming from 13 to 30% and in skiing from 0 to 9%. Prolonged use of the prosthesis (up to 9 years) had no significant deteriorating effect on the intensity of the recreation exercises. The number of those who were able to cycle or swim preoperatively was greater than that of those who were able to walk at that time. Cycling and swimming are especially valuable forms of physical exercise after total hip replacement because the load placed by the body weight on the hip joint is reduced.

The influence of total hip replacement on selected activities of daily living and on the use of domestic aid.

The effect of total hip replacement (McKee-Farrar and Brunswik prostheses) on selected activities of daily living and on the use of domestic aid in these activities was evaluated by interviewing 539 patients operated on. The mean age of the patients was 64.7 years and the mean follow-up time 4.2 years. After eliminating other diseases affecting mobility, a "proper" series of 294 patients was obtained. There was marked improvement in all activities. Walking ability was limited in 95% before and in 12% after the operation. The proportion of those unable to clean their homes decreased from 67% to 16%, to shop from 46% to 10%, to tie their shoes from 75% to 29%, to pull on stockings from 43% to 3% and to dress in other ways from 30% to 1%. The proportion of patients who were able to take care of themselves increased from 21% to 62%. The reliability of the interview was tested by comparing some objective observations with the information given by the patients. Thus a correlation was observed between the ability to walk and shop on the one hand, and pull on stockings and the flexion range of the hip, on the other.

Records based on clinical examination as an indicator of alcohol involvement in injuries at emergency stations.

Clinical detection of alcohol involvement (AI) and its recording (ethyl sign) in accident patients was evaluated by comparing the ethyl signs with blood alcohol concentrations (BAC) in 1012 injury victims. Of the 337 BAC-positive cases 50% had a positive ethyl sign, while an additional 13% had some reference to alcohol in their patient notes. Thus, the overall recording rate was 63%. Computer analysis of the statistics from the same emergency station revealed positive ethyl signs in 13.5% of all the 44 372 patients in 1973. The drunken victims of falls (44%) and fights & assaults (26%) formed the main bulk (70%) of all drunken injury patients. Ethyl sign was found to be a specific, though not a sensitive, indicator of AI and a useful device for studying the strain alcohol places upon the emergency services, statistically.

The effect of time factors on blood alcohol levels in accident victims.

Variations of alcohol involvement (AI) by time as well as the effect of the time interval between the last alcohol intake and accident occurrence, arrival, and specimen collection on blood alcohol concentrations (BAC) were studied in 1012 accident victims. In was found that 53% of accidents on Saturdays were alcohol-related, the corresponding percentage being 39% on Fridays and Sundays and 31% on other days. AI rose from its lowest figure (16%) in the morning to its highest (67%) in the following small and early hours. Most of the alcohol-involved accidents occurred with rising blood alcohol suggesting that this stage of intoxication might have a higher injury risk than the later stage with decreasing blood alcohol. The delay before arrival and specimen collection often led to a drop in BAC values which should be remembered when planning studies on AI in accidents and when interpreting the results of such investigations.

A case-control study on alcohol as a risk factor in pedestrian accident. A preliminary report.

Alcohol as a risk factor in pedestrian accidents was studied so that the BACs were measured by gas chromatography in 341 accident patients and by ASD-breathalyzers in 682 sex-, site-, and time-matched pedestrians not involved in accidents. Alcohol was found in the blood in 53% of the accident cases and in 15% of the controls. The RR, if 1.0 at zero BAC, was 0.59 at BAC 0.3-0.5, 2.2 at 0.6-1.0, 6.8 at 1.1-1.5, 13 at 1.6-2.0, and 29 at BACs of over 2.0 g/l.

Blood alcohol levels in injury victims at the emergency station of a rural central hospital.

Blood alcohol was determined in 182 consecutive adult injury victims at the emergency station of a rural central hospital during a fortnight in March 1974. In 30% of them alcohol was found in the blood. The percentage was 38 in males and 15 in females. No significant differences in alcohol involvement (AI) between social classes were noted. During the night 62% of the patients had ingested alcohol. The injuries on Saturdays were more often alcohol-involved (54%) than on other days of the week (26%). AI was very frequent (86%) in the victims of fights, assaults, and suicide attempts, while it was only rarely (9%) seen in industrial accidents. AI was clinically detected in 72% of the cases with positive blood alcohol concentrations. It can be concluded from the results of this and other studies referred to, that the AI rate for fresh injuries of adults at the Pinnish emergency stations was about 30-35%.

Blood alcohol levels in a series of injured patients with special reference to accident and type of injury.

Blood alcohol was determined in 1012 injury victims. It was found that the alcohol involvement (AI) rate was 37% in the total number of patients, 19% in industrial, 38% in traffic, 36% in home, 45% in other freetime accidents, and 69% in the victims of fights, assaults, and suicide attempts. The most common external cause of injury was falling (447 cases) with an AI rate of 38%, while the 172 other nontraffic true accident cases had a rate of 24%. The road and stairs were the usual places of falls while intoxicated. Head injuries had a high (47%) and upper extremity injuries a low (25%) AI rate. Tibial and ankle fractures were also very often associated with alcohol intake. Contrarily to traffic and industrial accidents the slightly injured at home and in other freetime environments had been drinking more frequently than the severely injured. The data suggest that alcohol is a powerful contributing factor in leisure-time injuries. Head and low leg are especially vulnerable in drunken persons. Not only driving but even when walking while intoxicated means taking risks.

Blood alcohol levels in accident victims.

The purpose was to study the frequency and distribution of alcohol involvement in accident patients. Blood alcohol was determined gas chromatographically in 1012 accident patients. Alcohol was found to be present in 37% with the following distribution by blood alcohol concentrations (BAC): 0.1--0.5 g/litre 7%, 0.6--1.5 g/litre 13%, over 1.5 g/litre 16%. There were 702 males and 310 females. Alcohol was found in the blood in 43% of the males and in 24% of the females. In both sexes the age group 35--44 had the highest incidence. The rate of alcohol involvement increased with decreasing social status and was remarkably high (54%) among unskilled workers. High BACs were so prevalent that a causal relationship is most probable. Further studies on the causal relationship in nontraffic accidents are needed to be able to take sensible preventive measures among high risk groups.

Falls and lying helpless in the elderly.

Twelve percent of men and 19% of women aged 65 years and over who sought medical attention after a fall, lie where they fell for 15 min or more after falling. The occurrence of a fall with a long period of lying helpless was associated in bivariate analyses with severe injury, an intrinsic or unknown mechanism of falling, falling indoors, poor functional capacity, use of walking aids, body temperature 37.5 degrees C or over, and serum potassium concentration under 3.5 mmol/l. A log-linear model showed that a fall with a lie of this kind was related independently to high body temperature, low serum potassium concentration, and severe injury. The occurrence of such a fall due to an extrinsic mechanism was related to poor functional capacity, but no similar relationship could be found when the fall was due to an intrinsic or unknown mechanism.

Times, places, and mechanisms of falls among the elderly.

Elderly persons among the population aged 65 years or over in the town of Pori, Finland, falls leading to medical treatment experiencing during one year, are described by age, sex, month, time of day, place, mechanism, estimated cause, previous falls, symptoms before falling, and activity when falling. Results indicate that the falls can be divided into two main categories: falls due to an extrinsic mechanism such as slipping or stumbling, and falls due to an intrinsic or unknown mechanism. Extrinsic mechanisms are more common in the younger age group (65-74 years), in whom falls are dependent on the time of day and amount of activity, and frequently happen outdoors while walking. Thus, slipping is a common extrinsic mechanism. Intrinsic or unknown mechanisms are more common in the older age group (75 years and above), in which estimated causes, such as orthostatic hypotension, fever, dementia, or joint disorders, can in many cases be detected. These cases are not dependent on time of day or month. Falls due to intrinsic or unknown mechanisms are related to rising from a lying or sitting position and lifting the head or turning the body before the fall. Before falling, some kinds of symptoms are more commonly experienced by persons falling due to an intrinsic or unknown mechanism than by those falling due to an extrinsic mechanism.
