Prevalence of osteoporosis in patients requiring spine surgery: incidence and significance of osteoporosis in spine disease

Abstract

The patients over 50 year-old who need spine operation have osteoporosis often. In conclusion, the number of spine operations in elderly patients is increasing and the incidence of osteoporosis in spine surgery patients is also increasing. We strongly recommend an evaluation for osteoporosis and post-operative treatment for osteoporosis in patients over 50 years old, especially for female patients.

Effect of various factors on pull out strength of pedicle screw in normal and osteoporotic cancellous bone models

“…However, due to reduced bone quality in an osteoporotic patient, this treatment technique is a major challenge for both the orthopedic surgeon and engineers. A high number of patients undergoing spine surgery over the age of 50 suffer from osteopenia and osteoporosis (46% and 31%, respectively) [45] . The common problems associated with pedicle screws are screw bending, breakage, and loosening.…”

Use of computed tomography for assessing bone mineral density

“…5 Despite the prevalence, a survey of spine surgeons recently found that only 22% performed DXA and only 11% checked metabolic laboratory values prior to performing noninstrumented fusion. 7 Multiple studies have explored the ability of diagnostic CT scanning to identify osteopenia and osteoporosis both based on HU values obtained from the spine 30,34 and proximal humerus.…”

Prevalence of Vitamin D Deficiency in Patients Undergoing Elective Spine Surgery: A Cross-Sectional Analysis

“…Decreased bone density secondary to osteoporosis and osteomalacia represents a serious risk factor for both bony fracture and spinal instrumentation failure (5,8,11,21,24). One of the most common and potentially treatable causes of pseudarthrosis or instrumentation failure in patients undergoing spinal fusion is poor bone mineral density (BMD) resulting from age-related vertebral osteoporosis (7).…”
