Serum osteocalcin in patients with spinal cord injury / 中华物理医学与康复杂志

ABSTRACT

Objective To explore the correlation between the time course of disease and bone metabolism changes in patients with spinal cord injury. Methods Data on serum osteocalcin(SO)measured by radioimmunoassay(RIA)from a database on 167 patients with spinal cord injury(SCI)were analyzed retrospectively.The patients were divided into four groups according to the time post-injurygroup A(＜3 months post-injury,n=44),group B(3-6 months post-injury,n=42),group C(7-12 months post-injury,n=37)and group D(＞12 months post-injury,n=44). Results The mean SO value in all 4 groups of patients was significantly higher than normal.The mean SO value of group B was significantly higher than that of group A,but not significantly different from that of group C.The mean SO value of group D was significantly lower than that of group C,but not significantly different from that of group A.Conclusion Serum osteocalcin is elevated in the early stages of SCI,and its subsequent de-cline is closely correlated with the time post-injury.
