- A total of 125 consecutive hip fracture patients were investigated regarding hip geometry. There were 33 men of mean age 76 +/- 10 years, and 92 women of mean age 78 +/- 9 years. Patients with previous hip surgery were excluded. Hip geometry (hip-axis length, width of collum femoris, and femoral shaft and neck-shaft angle) were registered on both plain radiographs and DEXA scans performed within 2 weeks after fracture. On the radiographs, the calcar femorale, the Singh index, and the femoral neck index (FNI) were also calculated and compared with earlier published values of bone mineral density hip in the hip fracture patients. The fracture cases were compared with controls, 192 DEXA scans and 163 radiographs, in patients without hip surgery or known hip disease. As measured on the DEXA scans we found a wider collum femoris and a wider femoral shaft in both the male and female fracture cases, compared to controls. Also, the fracture cases showed signs of osteoporosis as measured by the calcar femorale, the Singh index, and the femoral neck index. These measurements showed good correlation with bone mineral density of the hip as measured by the DEXA scans.

- Objectives. To study whether there is an increased fracture incidence following thyrotoxicosis. Design. A case-control study. Setting. Malmo University Hospital, Malmo, Sweden. Subjects: All patients (n = 333) from the population of Malmo who were treated for thyrotoxicosis for the first time during the 5-year period 1970-74. A total of 618 controls were selected from the local municipality registry in Malmo. For each case the aim was to randomly select two age- and gender-specific controls, alive in 1993 and born the same year and month as the case. Main outcome measures. Fracture incidence. Results. Comparing survivors, there were no differences in the percentage of individuals with fractures (all, fragility, non-fragility) between the patients and the controls. Comparing all individuals and including all fractures, the percentage of individuals with fractures in the entire female patient group (24.6%) was lower (P < 0.05) than in female controls (33.1%). There was a similar but non-significant pattern between male patients and controls. The mean number of all fractures was lower in male patients than in controls (P < 0.05), but no significant difference was noted between female patients and controls. For fragility fractures, there were no significant differences in the percentage of individuals with fractures or in the mean number of fractures between female or male patients and controls. Conclusion. In conclusion we found no increased incidence of fragility fractures in patients with previous thyrotoxicosis as compared with controls. Our results do not support the suggestion that screening for osteoporosis should be performed in patients with previous thyrotoxicosis.

Remodeling of the spinal canal deformed by trauma
- 1997

Ingår i: Journal of Spinal Disorders. - 0895-0385. ; 10:2, s. 157-161
-
Tidskriftsartikel (refereegranskat)abstract
- Computed tomography (CT) examinations and functional scores were evaluated in 28 patients with thoracolumbar fractures with intraspinal fragments, of whom 20 underwent operation. The cross-sectional area and the sagittal and frontal diameters of the spinal canal were measured after the injury, postoperatively, and at follow-up (mean, 6 years). The operative reduction significantly increased both diameter and area of the spinal canal. During follow-up, a further significant increase of the sagittal diameter and the area was noted, in both surgically and conservatively treated patients. There was no difference in remodeling between the groups. Six patients in the surgically treated group had neurologic deficits at admission, five had improved, and one remained unchanged at follow-up. The presence or absence of intraspinal fragments should not influence the treatment strategy per se in cases without neurologic signs.

Balance and gait performance in an urban and a rural population

- OBJECTIVE: To compare the differences in standing balance and gait performance between two populations, correlated with age and physical activities of daily living. DESIGN: A cross-sectional study. SETTINGS: Malmo, the third largest city in Sweden, and Sjobo, a typical agricultural community 60 km east of Malmo. PARTICIPANTS: Participants were 570 men and women from the urban community (urban) and 391 from the rural community (rural), born in 1938, 1928, 1918, and 1908, and women born in 1948. The two cohorts were subdivided into true urbans, who had lived only in the city (n = 269), and true rurals, who had never lived in a city (n = 354). MEASUREMENTS: Information about workload, housing, spare time activities, medication, and illness during different decades of life was gathered using two questionnaires. The first questionnaire was sent to the home after agreement to participate, and the second was presented at the test session. The clinical measurements were standing balance, gait speed, and step length. RESULTS: The urban subjects had significantly (P < .001) impaired balance compared with rural subjects. This difference increased with increasing age. The urban subjects walked faster than the rural subjects (P < .001), and the urban subjects used fewer steps than their rural counterparts (P < .001). Spare time activities had a significant influence on the above tests, but, except for gait velocity (P = .011), workload was of minor importance according to analysis of covariance. CONCLUSION: Background factors such as usual daily activities of living and lifestyle seem to be of importance when evaluating and comparing different populations with respect to their balance and gait performance.
