- ACRONYMCOOS
- hypothesisOsteoporosis is common in patients with SCI and often causes fractures and is undertreated.
Besides immobilization, other (endocrine) disturbances such as hypogonadism and/or growthhormone deficiency, which are seen after SCI with accompanying Traumatic Brain Injury (TBI) might also aggravate loss of BMD. Also, The decentralized autonomic nervous system with periodic high sympathetic activity (often seen in SCI patients), might be related to the frequency of occurrence and severity of osteoporosis.

- Brief summarySpinal cord injury (SCI) is a major risk factor for osteoporosis due to immobilization. Limited data suggest that osteoporosis has a prevalence of approximately 60-80% in men with SCI and fractures occur in 20 to 35% of patients. Despite this high prevalence, patients are not usually analyzed for the presence of osteoporosis and data on prevalence and incidence of osteoporosis and fractures are limited and although bisphosphonates have been shown to be effective in reducing bone loss after acute SCI, chronic SCI is not seen as an indication for secondary prevention with antiosteoporotic medication.
This study aims to determine prevalence of osteoporosis, fractures and active treatment in patients with SCI since more than 1 year. Also we will investigate other possible pathophysiologic processes as accompanying traumatic brain injury or autonomic dysfunction, that might contribute to the high bone loss in SCI. It is a 2-year monocenter, cross sectional observational study in which 40 wheelchair-bound patients with traumatic SCI since more than 1 year and 40 healthy controls will be investigated for osteoporosis according to WHO-criteria. Data regarding fractures, quality of life, level, completeness and duration of SCI will be collected. In case of traumatic brain injury pituitary hormone levels will be measured. Autonomic (dys)function will be investigated. After completion of the study, participants will receive a treatment advice.
