To investigate the clinical characteristics of insufficiency fracture of the spine, patients aged 65 years or older, who had been hospitalized for acute low back pain without either an acute traumatic event or a previous history of malignant disease, were examined by plain radiographs and technetium-99m methylene disphosphonate bone scanning. Fifteen patients were diagnosed as having a vertebral insufficiency fracture on the basis of: (a) radiographic oseteopenia of the vertebra; (b) positive bone scan images; and (c) no episode of newly identified malignant disease in a subsequent 1 year follow up. These patients were analysed with respect to age, gender, bone mineral density, the number and distribution of the affected vertebrae, the extent of vertebral deformity, and consistency between radiographic and bone scan findings. Vertebral insufficiency fractures exhibited: (a) strict female predominance; (b) concave deformity of the affected vertebra; (c) a wide range of the vertebral height ratios and fracture distribution; and (d) low consistency between the vertebral deformity assessed by the lateral radiograph and positive activity on bone scanning. These findings represent a unique clinical feature of vertebral insufficiency fracture, and also emphasize the difficulty of radiographic diagnosis, as well as the importance of a comprehensive diagnostic approach.
