Changes of bone mineral density in distal femur and proximal tibia in patients with spinal cord injury / 中国康复理论与实践

ABSTRACT

ObjectiveTo investigate the changes of bone mineral density of distal femur and proximal tibia in patients with spinal cord injury. MethodsNine 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. ResultsCompared 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). ConclusionWithin one year after the onset of spinal cord injury, the bone mineral density of distal femur and proximal tibia decreases.
