Abstract:

Objective To investigate the changes of bone mineral density of distal femur and proximal tibia in patients with spinal cord injury.

Methods Nine inpatients with spinal cord injury in Beijing Bo'ai Hospital for rehabilitation from November, 2018 to January, 2021 were recruited. The bone mineral density of distal femur, proximal tibia, total hip and femoral neck at admission and six months after admission was measured.

Results Compared with the results of admission, the bone mineral density of distal femur, proximal tibia, total hip and femoral neck decreased significantly six months after admission (∣Z∣ > 2.265, P < 0.01). The percentage of decreased bone mineral density in the femoral neck was inversely correlated with the lower extremity movement score at the second measurement (r = -0.515, P = 0.035).

Conclusion Within one year after the onset of spinal cord injury, the bone mineral density of distal femur and proximal tibia decreases.

Key words: spinal cord injury, bone mineral density, distal femur, proximal tibia
