Objectives: Osteoporosis is a debilitating condition with rising frequency of fragility fractures with advancing age. Life expectancy increases in developing societies with the emergence of osteoporosis. There is a need for a simple protocol to diagnose fractures that merit treatment for osteoporosis.
Methods: Evaluation of all consecutive lateral chest radiographs performed at the National Hospital in the capital city in Greenland over a 3-month period for vertebral body heights at the anterior, middle and posterior regions. Use of anti-osteoporotic drug was evaluated from records of dispensed drugs from Greenland National Pharmacy.
Results: 1869 vertebrae were evaluated on radiographs from 203 subjects. On average 9.2 vertebrae (range 5-13) qualified for evaluation in each individual. Median (range) age was 55 (30-82) years. Any vertebral deformity above 25 (20) % was seen in 28.6 (50.2) %. More than one fracture was seen in 10.3 (27.1) %. Fractures occurred in 18.5 (36.9) % of patients from the General Medicine Clinic and in 33.3 (56.5) % of inpatients (p = 0.029). The occurrence of vertebral fractures increased with age (p < 0.001) and hosting more than one vertebral fracture was markedly more frequent after the age of 60 years [OR, 95 % CI 9.6, 3.1-30 (5.7, 2.9-11); p < 0.001] after correction for gender in logistic regressions. The National Pharmacy handed out anti-osteoporotic drugs equal to the treatment of 36 individuals.
Conclusions: Vertebral fractures that merit treatment can be readily diagnosed from lateral chest radiographs taken in routine clinical work-up. They are common in Greenland as demonstrated by this simple protocol to improve diagnosis and treatment of osteoporosis in a developing society.
