Significant Loss of Areal Bone Mineral Density Following Prolonged Bed Rest During Treatment With Teriparatide
Abstract
We present of a case of severe osteoporosis with thoracic myelopathy secondary to nontraumatic T8 compression fracture managed nonsurgically with 3.5 months of bed rest. Despite treatment with teriparatide starting at initial presentation, 1-year follow-up dual energy x-ray absorptiometry scan revealed a significantly greater than expected 19% reduction in lumbar spine bone mineral density (BMD) and a 6% reduction in total hip density. Daily alcohol consumption, severe osteoporosis at baseline, and immobilization secondary to transient myelopathy treated with strict bed rest all likely contributed to unexpected BMD findings.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
