Key takeaways:
- Patients had poor compliance with wearing hyperextension orthoses for nonoperative treatment of osteoporotic vertebral fractures.
- Women wore the hyperextension orthoses significantly longer than men.
Patients had poor compliance with wearing hyperextension orthoses for nonoperative treatment of osteoporotic vertebral fractures, according to results published in The Spine Journal.
In addition, researchers noted that women tended to wear hyperextension orthoses significantly longer compared with men.

“Overall, compliance with wearing [hyperextension orthoses] HOs is poor and shows great variability with significant gender-dependency but not associated with BMI, age, or pain-level,” Pascal R. Furrer, MD, of the department of orthopedics at Balgrist University Hospital, University of Zurich, and colleagues wrote.
In a single-center, single-blinded, prospective study, Furrer and colleagues assessed compliance of wearing hyperextension orthoses among 18 patients with thoracolumbar osteoporotic vertebral fractures. Researchers defined compliance as wearing hyperextension orthoses for 15 hours per day. Researchers calculated wear time using hidden temperature-based sensors and performed clinical and radiographic evaluation at 2, 4 and 6 weeks.
Furrer and colleagues found patients had a mean hyperextension orthoses wear time of approximately 5.5 hours per day and an overall compliance rate of approximately 37%.
In addition, researchers found that women were more likely to wear the hyperextension orthoses for longer periods compared with men (about 6.5 hours per day vs. 2.9 hours per day).
“The wearing time did not have an influence on kyphotic progression of the osteoporotic fractured segment, nor on clinical outcome at short term in this study on a small sample size, which needs to be proven with further studies,” the co-authors wrote in the study.
“The data from this study contribute in part to the controversy surrounding the use of hyperextension orthoses, which is a constant discussion in the literature with major impact to thousands of patients,” the researchers added.
