Objective: The purpose of this study is to investigate the prevalence of osteoporosis in the patients with back pain and the necessity of pre-operative measurement of bone mineral density(BMD) in patients requiring spine surgery.
Methods: From March 2005 to February 2012, we measured 1310 patients of BMD by the dual-energy X-ray absorptiometry in the patient with back pain. According to each age group of a decade, we compared BMD of the patients among the conservative treatment group (group A), spine surgery group (group B) and major spine surgery group except vertebroplasty and kyphoplasty (group C). We also evaluated the prevalence of osteoporosis and osteopenia of the three groups.
Results: Among 1217 patients older than 50 years old, 483 patients (332 female, 151 male) had undertaken spine surgery. Out of the 332 female patients, there were 222 (66.9%) with osteoporosis, and 82 (24.7%) with osteopenia. Among the 151 male patients, there were 55 (36.4%) with osteoporosis, and 56 (37.1%) with osteopenia. 276 patients (171 female, 105 male) had undertaken major spine surgery except vertebroplasty and kyphoplasty. Out of 171 female patients, there were 83 (48.54%) with osteoporosis, and 63 (36.8%) with osteopenia. Among 105 male patients, there were 22 (21%) with osteoporosis, and 45 (42.9%) with osteopenia. The prevalence of osteoporosis over 50 years old was respectively 54.6% in conservative treatment group, 57.3% in whole spine surgery group, and 38.2% in major spine surgery group.
Conclusion: The patients over 50 years old who have back pain symptom often have osteoporosis. We recommend pre-operative evaluation of osteoporosis for patients requiring spine surgery, especially over 50 years old in female patients.
