Early mobilization reduces the medical care cost and the risk of disuse syndrome in patients with acute osteoporotic vertebral fractures.

ABSTRACT

STUDY DESIGN: A retrospective observational study. PURPOSE: To compare two conservative treatments for acute osteoporotic vertebral fractures (OVFs). OVERVIEW OF LITERATURE Several studies have reported conservative treatments for OVFs in terms of using a brace, rehabilitation, and bed rest. However, there is no consensus about the conservative treatment for OVFs. METHODS: We evaluated 68 patients with acute OVF treated in our hospital from 2007 to 2011. Thirty-four patients treated in prolonged bed rest (PBR) regimen underwent rehabilitation wearing a Jewett's brace after three weeks of bed rest. In contrast, the other 34 patients underwent rehabilitation wearing a Jewett's brace as soon as possible, which we called a stir-up (SU) regimen. We compared two treatment groups for medical costs, hospital length of stay (LOS), pain according to the numeric rating scale (NRS), the activities of daily living (ADL), and imaging studies. RESULTS: The average hospital LOS was significantly shorter in patients treated by the SU regimen, which resulted in the medical costs reduction. There was no significant difference in the NRS through 6 months between the two groups. Although many patients in both groups experienced at least one level reduction in ADL at 6 months after the injury, patients in the SU group tended to maintain their pre-injury ADL, which almost agrees with past reports. In terms of imaging studies, patients in the PBR group showed milder vertebral compression rate over time. Pseudoarthrosis occurred in 2 patients in the SU group, who presented with mild pain, which had little influence on their daily lives. CONCLUSION: We compared two conservative treatments for OVFs. Early rehabilitation was useful treatment for OVFs to minimize the risk for disuse syndrome, maintain pre-injury ADL status, and reduce the medical costs.
