A total off 66,346 patients aged > or = 65 years who sustained a fracture of the femoralneck or intertrochanteric region from 1985 to 1996 comprised the study population. Hip fractures were more likely to occur in the winter than in any of the other seasons (P<.001). Factors significantly correlated with hip fractureincluded minimum daily temperature (r=.167, P<.001), daily wind speed (r=.166, P<.001), maximum daily temperature (r=.155, P<.001), minutes of sunshine (r=.067, P<.01), and average relative humidity (r=.033, P=.03). A greater number of hip fractures occurred in colder months, withambient temperature rather than any adverse circumstances related to rainor snowfall associated most closely to injury. As most fractures occurredindoors, precipitation is less likely to play a part in hip fracture occurrence in this population.

The purpose of the present study was to compare the rate of bleeding complications in a group of patients who required intravenous heparin therapy for the treatment of thromboembolism after total hip or knee arthroplasty with the rate in a control group of patients who received only prophylactic anticoagulation. The postoperative courses of forty-four consecutive patients who were managed with intravenous administration of heparin and oral administration of warfarin for the treatment of a thromboembolic event following unilateral total hip or knee arthroplasty were compared with those of a control group of 376 consecutive patients who had these same procedures but did not have a thromboembolic complication. The patients in the control group were managed with prophylactic anticoagulation with use of enoxaparin. Sixty-eight percent (thirty) of the forty-four patients in the heparin group received the initial dose of heparin on or before the fourth postoperative day, and 82 percent (thirty-six) received an initial bolus of 5000 units of heparin at the initiation of therapy. The rate of bleeding complications was 9 percent (four of forty-four) in the heparin group, compared with 6 percent (twenty-three of 376) in the control group (p = 0.44). The mean transfusion requirement in the heparin group (1.8 units of packed red blood cells) was significantly greater than that in the control group (0.8 unit) (p < 0.0001). Three of the four patients who had a bleeding complication while receiving heparin and warfarin had coagulation parameters that were substantially higher than recommended levels. The mean duration of hospitalization in the heparin group (fifteen days) was significantly longer than that in the control group (seven days) (p < 0.0001). The results of the present study suggest that the use of intravenous heparin therapy for the treatment of thromboembolism in the early postoperative period after total joint arthroplasty is associated with a rate of bleeding complications that is similar to that associated with the use of prophylactic anticoagulation with use of enoxaparin alone. One should expect an increased transfusion requirement and a longer duration of hospitalization for patients who require intravenous heparin therapy for the treatment of a thromboembolic event.

The symptom survey was conducted to determine the magnitude and musculoskeletal injury characteristics among the cement and concrete workers and identify the most problematic work-related activities and job factors that might have contributed to the occurrence of these disorders. Findings revealed that a large proportion of the laborers (77%) experienced at least one musculoskeletal disorder in the last year. Low back pain was reported as the most frequently experienced symptom (66%). 'Working while in pain' the concrete workers perceived as the major problem in the trade. Other problematic work-related activities included 'bending or twisting the back', 'work in hot, cold or wet conditions', and 'handling heavy objects'. Most of the laborers (82%) requested on-the-job safety training. Survey results combined with the outcomes of focus groups discussions and work site observations were used in the design of a training program aimed at the prevention of musculoskeletal morbidity in the trade. The program incorporated ergonomics principles, hazard recognition, safe work practices, problem solving and personal protection in the training curriculum for membership of the trade.

Our descriptive study was of all hip fracture cases admitted to NYS hospitals during that period. Case data were obtained from the Statewide Planning and Research Cooperative System (SPARCS) of the NYS Department of Health. US Census Bureau population estimates were obtained for each year from 1985 to 1996 to compute the annual hip fracture rate for each NYS county. These rates were adjusted for differences in age, gender, and race and were compared using logistic regression. Approximately 14,000 hip fractures occurred annually from 1985 to 1996. The annual rate (number of hip fractures per 1000 population) decreased from 6.4 in 1985 to 5.3 in 1996. White women aged 85 or older had the highest rate (26/1000); nonwhite men aged 65 to 69 had the lowest rate (<1/1000). Statewide annual rates decreased slightly over time, but this change was not reflected in all age, gender, and race subgroups. There was important, consistent variation in county rates after adjustment for age, gender, and race. Other researchers have identified geographic variation in national rates, but the postulated environmental and weather-related factors (eg, water fluoridation use; rainfall and sunshine amounts) have explained only a small proportion of this variation. Identification of risk factors that can better explain regional rate variation may lead to development of intervention strategies that could significantly reduce the risk for hip fracture among people 65 or older.

The purpose of this prospective study was to compare two different types of tape to determine whether the type of tape influences the rate of blister formation. Ninety-nine patients (100 hips) were enrolled in the study. Patients were randomized into one of two treatment groups: one treated with a nonstretchable silk tape and one treated with a perforated, stretchable cloth tape. After surgery, the assigned tape was applied over the postoperative dressing with care not to produce skin tension. At the first dressing change, the presence or absence of blisters was recorded as were the number, size, location, and type of any blisters. The presence or absence of tape blisters was recorded at the time of each subsequent dressing change. A tape blister developed on twenty-five hips in twenty-five patients. The risk of a blister developing was 41% (twenty of forty-nine patients) ...

Postoperative radiographs of 40 patients who underwent intramedullary nailing of their tibial shaft fractures using picture archiving communication systems were retrieved. In phase one and two of this investigation, tibial nail lengths were measured using "measuring distance" and "measure calibration" tools displayed on the respective digital systems. Phase 3 of this study involved 5 tibial Sawbones (Pacific Research Laboratories, Vashon, Wash) radiographically captured on the picture archiving communication systems with a radiograph marker of known length. Using the "measuring distance" and "measure calibration" tools in phases one and two did not result in accurate measurements. Of 40 digital radiographic images measured and calibrated with the on-screen ruler and...

A comprehensive search of Medline using the key words "radius" and "fracture" revealed over 4,000 articles. After limiting the search to clinical trials in English and excluding pediatric and geriatric age groups as well as biomechanical and animal studies, 615 abstracts were identified in the period from 1976 to May 1998. Thirty-one articles met the inclusion and exclusion criteria. These included two prospective randomized comparative trials, two non-randomized comparative trials, one half prospective case series and half historical control, and 27 papers on case series. Four papers dealt with external fixation versus closed reduction and cast treatment and one paper looked at open reduction internal fixation with or without additional external fixation. There was insufficient data to perform ...

This study evaluates the impact of the Spine Team, a multidisciplinary care group that included physicians, physical therapists, and a clinical psychologist, for the treatment of active-duty service members with work-disabling, nonspecific low back pain at the Naval Medical Center, Portsmouth, VA, USA. We compared the impact of the introduction of the Spine Team in limiting disability and attrition from work-disabling spine conditions with the experience of the Naval Medical Center, San Diego, CA, USA, where there is no comparable spine team. Is a multidisciplinary spine team effective in limiting disability and attrition related to work-disabling spine conditions as compared with the current standard of care for US military active-duty service members? This is a retrospective, pre-/post-study with a separate, concurrent control group using administratively collecte...

Data were analyzed for 51,003 patients (> or = 65 years old) admitted with femoral neck fractures to New York state hospitals between 1985 and 1996. The primary outcome examined was in-hospital mortality. Associations between type of surgical procedure and outcome were assessed using a multiple logistic regression model, adjusting for patient age, sex, race, number of comorbidities, and residence in a nursing facility before hip fracture. Approximately 30% of the study group had undergone open or closed reduction and internal fixation; the other 70% had undergone hemiarthroplasty. Forty-six percent of the internal fixation group and 56% of the hemiarthroplasty group were 85 years old or older (P < .001). Median hospital stays were 13 days for the internal fixation group and 15 days for the hemiarthroplasty group (P < 0...

Patients were followed for 2 years after surgery. Compared with GA, SA resulted in mean reductions of 12% in operative time, 25% in estimated intraoperative blood loss, 38% in rate of operative blood loss, and 50% in intraoperative transfusion requirements. Compared with patients receiving GA, patients receiving SA had higher hemoglobin levels on postoperative days 1 and 2 and a 20% lower total transfusion requirement. SA appears superior to GA for this procedure.

The return rate of the survey was 70.2%. The outcome revealed that 65% of the mason tenders experienced low back pain during the year prior to the survey, 35% of them were absent from work, and 45% visited a physician due to the symptoms. The job-related characteristics perceived by the mason tenders as the most problematic included bending or twisting the back working in the same position for long periods of time, working overhead or away from the body, and working near or at physical limits. The study results were incorporated in the design and implementation of low back pain prevention program that trained the union trade instructors in ergonomic hazard recognition and problem solving, and targeted the mason tenders.

To identify factors that predict work retention 24 months after treatment in patients with nonspecific LBP. There is evidence that select physical, psychologic, and psychosocial factors are related to positive outcome for work-related nonspecific LBP. However, there is very little information related to work retention following an episode of nonspecific LBP. This is an exploratory study to identify select physical and psychosocial factors related to work retention. Patients who returned to work after treatment (n = 67) were followed for 2 years. Physical baseline measures included tests of flexibility, strength, and functional capacity. Psychosocial baseline measures were The Symptoms Checklist 90-R, The Pain Beliefs and Perceptions Inventory, The Oswestry Scale of perceived disability, The Work Stress Inventory, and The Quality of Life Scale. All physical parameters, perceived disability, and quality of life were tested before and after treatment. The dependent variable, work retention, was defined as the number of days that the subject worked during the 2-year follow-up period. Survival analysis was used to establish the predictive model. The average time out of work before treatment was 9 months (standard deviation 12.8) for 67 subjects (mean age 40 years [standard deviation 9.6]), including 18 females and 49 males. There were 18 participants (25%) that had interruption of work retention at follow-up. Average work retention was 362 days (range 47-682). Variables that reached a P value of &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.10 in the bivariate analysis were included in the multivariate analysis. They were trunk flexion (hazard ratio [HR = 2.4], 95% confidence interval [CI] 1.24-4.38; P = 0.01), trunk extension (HR = 2.1, 95% CI 1.02-4.16; P = 0.04), the somatization scale from the Symptom Checklist 90 revised (HR = 2.0, 95% CI 1.03-4.05; P = 0.04), and the obsessive-compulsiveness scale from the Symptom Checklist 90 revised (HR = 0.4, 95% CI 0.12-1.15; P = 0.09). Results showed that post-test trunk flexion, somatization, and obsessive compulsiveness predicted work retention (final trunk flexion HR = 2.5 [95% CI 1.26-4.79; P = 0.01], somatization scale HR = 2.5 [95% CI 1.25-4.93; P = 0.01], and obsessive compulsion HR = 0.2 [95% CI 0.07-0.77; P = 0.02]). Psychosocial and physical factors are associated with work retention for patients with nonspecific LBP. The predictive value of certain constructs may vary with the time when they are assessed and how outcome is operationalized. Further studies are needed to confirm these findings.

Our descriptive study was of all hip fracture cases admitted to NYS hospitals during that period. Case data were obtained from the Statewide Planning and Research Cooperative System (SPARCS) of the NYS Department of Health. US Census Bureau population estimates were obtained for each year from 1985 to 1996 to compute the annual hip fracture rate for each NYS county. These rates were adjusted for differences in age, gender, and race and were compared using logistic regression. Approximately 14,000 hip fractures occurred annually from 1985 to 1996. The annual rate (number of hip fractures per 1000 population) decreased from 6.4 in 1985 to 5.3 in 1996. White women aged 85 or older had the highest rate (26/1000); nonwhite men aged 65 to 69 had the lowest rate (<1/1000). Statewide annual rates decreased slightly over time, but this change was not ref...

A total off 66,346 patients aged > or = 65 years who sustained a fracture of the femoralneck or intertrochanteric region from 1985 to 1996 comprised the study population. Hip fractures were more likely to occur in the winter than in any of the other seasons (P<.001). Factors significantly correlated with hip fractureincluded minimum daily temperature (r=.167, P<.001), daily wind speed (r=.166, P<.001), maximum daily temperature (r=.155, P<.001), minutes of sunshine (r=.067, P<.01), and average relative humidity (r=.033, P=.03). A greater number of hip fractures occurred in colder months, withambient temperature rather than any adverse circumstances related to rainor snowfall associated most closely to injury. As most fractures occurredindoors, precipitation is less likely to play a part in hip fracture occurrence in this population.

The symptom survey was conducted to determine the magnitude and musculoskeletal injury characteristics among the cement and concrete workers and identify the most problematic work-related activities and job factors that might have contributed to the occurrence of these disorders. Findings revealed that a large proportion of the laborers (77%) experienced at least one musculoskeletal disorder in the last year. Low back pain was reported as the most frequently experienced symptom (66%). 'Working while in pain' the concrete workers perceived as the major problem in the trade. Other problematic work-related activities included 'bending or twisting the back', 'work in hot, cold or wet conditions', and 'handling heavy objects'. Most of the laborers (82%) requested on-the-job safety training. Survey results combined with the outcomes of focus groups discussions an...

Data were analyzed for 51,003 patients (> or = 65 years old) admitted with femoral neck fractures to New York state hospitals between 1985 and 1996. The primary outcome examined was in-hospital mortality. Associations between type of surgical procedure and outcome were assessed using a multiple logistic regression model, adjusting for patient age, sex, race, number of comorbidities, and residence in a nursing facility before hip fracture. Approximately 30% of the study group had undergone open or closed reduction and internal fixation; the other 70% had undergone hemiarthroplasty. Forty-six percent of the internal fixation group and 56% of the hemiarthroplasty group were 85 years old or older (P < .001). Median hospital stays were 13 days for the internal fixation group and 15 days for the hemiarthroplasty group (P < 0...

The purpose of the present study was to compare the rate of bleeding complications in a group of patients who required intravenous heparin therapy for the treatment of thromboembolism after total hip or knee arthroplasty with the rate in a control group of patients who received only prophylactic anticoagulation. The postoperative courses of forty-four consecutive patients who were managed with intravenous administration of heparin and oral administration of warfarin for the treatment of a thromboembolic event following unilateral total hip or knee arthroplasty were compared with those of a control group of 376 consecutive patients who had these same procedures but did not have a thromboembolic complication. The patients in the control group were managed with prophylactic anticoagulation with use of enoxa...

Patients were followed for 2 years after surgery. Compared with GA, SA resulted in mean reductions of 12% in operative time, 25% in estimated intraoperative blood loss, 38% in rate of operative blood loss, and 50% in intraoperative transfusion requirements. Compared with patients receiving GA, patients receiving SA had higher hemoglobin levels on postoperative days 1 and 2 and a 20% lower total transfusion requirement. SA appears superior to GA for this procedure.

The return rate of the survey was 70.2%. The outcome revealed that 65% of the mason tenders experienced low back pain during the year prior to the survey, 35% of them were absent from work, and 45% visited a physician due to the symptoms. The job-related characteristics perceived by the mason tenders as the most problematic included bending or twisting the back working in the same position for long periods of time, working overhead or away from the body, and working near or at physical limits. The study results were incorporated in the design and implementation of low back pain prevention program that trained the union trade instructors in ergonomic hazard recognition and problem solving, and targeted the mason tenders.

To identify factors that predict work retention 24 months after treatment in patients with nonspecific LBP. There is evidence that select physical, psychologic, and psychosocial factors are related to positive outcome for work-related nonspecific LBP. However, there is very little information related to work retention following an episode of nonspecific LBP. This is an exploratory study to identify select physical and psychosocial factors related to work retention. Patients who returned to work after treatment (n = 67) were followed for 2 years. Physical baseline measures included tests of flexibility, strength, and functional capacity. Psychosocial baseline measures were The Symptoms Checklist 90-R, The Pain Beliefs and Perceptions Inventory, The Oswestry Scale of perceived disability, The Work Stress Inventory, and The Quality of Life Scale. All physical parameters, perceived disability, and quality of life were tested before and after treatment. The dependent variable, work retention, was defined as the number of days that the subject worked during the 2-year follow-up period. Survival analysis was used to establish the predictive model. The average time out of work before treatment was 9 months (standard deviation 12.8) for 67 subjects (mean age 40 years [standard deviation 9.6]), including 18 females and 49 males. There were 18 participants (25%) that had interruption of work retention at follow-up. Average work retention was 362 days (range 47-682). Variables that reached a P value of &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.10 in the bivariate analysis were included in the multivariate analysis. They were trunk flexion (hazard ratio [HR = 2.4], 95% confidence interval [CI] 1.24-4.38; P = 0.01), trunk extension (HR = 2.1, 95% CI 1.02-4.16; P = 0.04), the somatization scale from the Symptom Checklist 90 revised (HR = 2.0, 95% CI 1.03-4.05; P = 0.04), and the obsessive-compulsiveness scale from the Symptom Checklist 90 revised (HR = 0.4, 95% CI 0.12-1.15; P = 0.09). Results showed that post-test trunk flexion, somatization, and obsessive compulsiveness predicted work retention (final trunk flexion HR = 2.5 [95% CI 1.26-4.79; P = 0.01], somatization scale HR = 2.5 [95% CI 1.25-4.93; P = 0.01], and obsessive compulsion HR = 0.2 [95% CI 0.07-0.77; P = 0.02]). Psychosocial and physical factors are associated with work retention for patients with nonspecific LBP. The predictive value of certain constructs may vary with the time when they are assessed and how outcome is operationalized. Further studies are needed to confirm these findings.
