Randomized trial of hemiarthroplasty versus internal fixation for femoral neck fractures: no differences at 6 years.

Background: Hemiarthroplasty has been shown superior to internal fixation for displaced femoral neck fractures (FNF) in the first 2 years. However, there are unanswered questions about the performance of hemiarthroplasty over the longer term compared with internal fixation.

Questions/purposes: We sought to compare hemiarthroplasty with internal fixation in terms of (1) outcomes scores for pain, hip function, and quality of life at a minimum of 5 years after surgery in a randomized trial.

Secular reduction of excess mortality in hip fracture patients >85 years.

Background: More than 20% of the hip fracture patients die within the first year after the incident. Few data are available on the trends in mortality following a hip fracture. The present aim was to study changes in excess mortality after hip fracture from 1978/79 up to 1996/97.

Changes in the vitamin D endocrine system and bone turnover after oral vitamin D3 supplementation in healthy adults: results of a randomised trial.

Background: There is uncertainty as to which intake of vitamin D is needed to suppress PTH and maintain normal bone metabolism throughout winter at northern latitudes. We aimed to investigate whether four weeks' daily supplementation with 10 μg vitamin D3 from fish oil produced a greater change in serum vitamin D metabolites, parathyroid hormone, and bone turnover in healthy adults compared with solid multivitamin tablets. Furthermore, it was studied whether age, gender, ethnic background, body mass index, or serum concentrations at baseline predicted the magnitude of change in these parameters.

[The treatment of femoral neck fractures].

Background: About 5000 people fracture their femoral neck every year in Norway. Mean age is about 83 years and about 3/4 are women. For more than 50 years the alternatives have been internal fixation or arthroplasty.

Vitamin D status in Sri Lankans living in Sri Lanka and Norway.

Vitamin D deficiency is common in non-Western immigrant groups living in Western countries. A comparison of vitamin D status in individuals who have emigrated and individuals who remain in their country of origin is needed in order to provide information about the effect of moving to northern latitudes. A total of 196 participants aged 30-60 years in a cross-sectional population-based study in Kandy, Sri Lanka (latitude 7 degrees north) and 242 Sri Lankans aged 31-60 years participating in a cross-sectional population-based study in Oslo, Norway (latitude 60 degrees north) were included in the analysis.

A randomised comparison of increase in serum 25-hydroxyvitamin D concentration after 4 weeks of daily oral intake of 10 microg cholecalciferol from multivitamin tablets or fish oil capsules in healthy young adults.

Many types of vitamin supplements are available on the market, but little is known about whether cholecalciferol obtained from fat-containing capsules differs in bioavailability from that of solid tablets. Our objective was to test whether 4 weeks of daily supplementation with 10 mug cholecalciferol given as a fish oil capsule produces a larger increase in serum 25-hydroxyvitamin D (s-25(OH)D) concentration compared with the same dose of cholecalciferol given as a multivitamin tablet. A total of seventy-four healthy subjects aged 19-49 years were initially included and fifty-five of these completed the study and fulfilled the inclusion criteria.
