Traumatic Spinal Cord Injury (TSCI) is one of the most incident pathology that causes irreversible physical sequels in young people. As TSCI patient’s life expectancy increases, they also end up living longer with the comorbidities that involve the spinal cord injury. One of the major secondary consequences involving TSCI is osteoporosis, which makes fractures by imminent trauma more frequent. This aggravates the health and causes the treatment to be expensive. The loss of bone mass in the spinal injured is not yet established in the literature. However, some factors have been linked to its protection or risk, yet the studies are controversial. Thus, there is no consensus about it. Moreover, the function of the biochemical parameters that are involved in the bone metabolism were not defined either, as well the rehabilitation therapies able to stop bone loss. As a result, in this controlled cross-sectional lineation research, we studied the possible risk/protection factors for the low bone mass density (BMD) in 57 men with TSCI, older than 18 years old. Factors connected to health, lifestyle, and physiotherapy were highlighted throughout a questionnaire. Lab analysis were carried out to characterize parameters such as parathyroid hormone, calcium, vitamin D, urea, and creatinine. The bone density was utilized to verify the individuals’ bone mass. After the data collection, the sample was divided between two groups, according to their bone mass: 38 were placed in this case group, BMD (z-score≤ -2,0DP), and 19 were placed in the control group, without BMD (z-score>-2,0DP). The collected variables were related to both denouements.Lastly, we found that the majority of subjects (66.6%) presented BMD in at least one of the three sites of interest studied (total body, lumbar spine and/or proximal femur). The total femur site was the one that presented more prevalence of BMD (45.5%). Inside this site, the sub-regions of intertrochanteric area and femoral neck presented a medium BMD in the studied population. The average serum levels of Vitamin D were localized in the insufficient range and there was no association among the biochemical parameters averages and the BMD of these individuals. After the adjust of confusion factors, three of these presented associations according to the variables associated to the BMD: the type of complete lesion (PR:1-0,76 CI 90%: 0,57-1,02), the Index of body mass (PR:1- 0,93 CI 90%: 0.89 – 0.98 ), and the walking training (PR:10,45 CI 90% 0,20 – 1,01). Thus, we can verify that people with incomplete TSCI have 24% of protection for BMD when compared to complete TSCI patients. For each BMI unit increasing there is a 7% protection for BMO; and patients that reported performing gait training during physiotherapy have 55% of protection for BMD when compared to patients that never did it.
