Abstract. This study was performed to evaluate the correlation between serum biochemical marker levels of bone metabolism and bone mineral density (BMD) in patients with ossification of the posterior longitudinal ligaments (OPLL). In addition, the efficacy of these markers in the prediction of the progression of OPLL was also examined. In 40 patients with OPLL, and in age- and gender-matched controls (n= 36), the levels of C-terminal extension peptide of type I procollagen (PICP) and intact osteocalcin were quantitated by a sandwich enzyme-linked immunosorbent assay as serum markers of bone formation. BMD of the whole body was measured using dual-energy X-ray absorptiometry. Serum PICP and intact osteocalcin levels were significantly increased in patients with OPLL. There was a significant correlation between serum bone formation marker levels and BMD in both the OPLL and the control groups. Patients with radiological progression of OPLL showed a level higher than the mean + 2 SD of controls in PICP, intact osteocalcin, and BMD. In addition, the levels of serum PICP and intact osteocalcin increased in correspondence with the progression of OPLL without statistical significance. In patients without any growth of OPLL, however, all the parameters were below the mean + 2 SD of controls. Thus, aggravation of bone formation activity was suggested to be closely correlated with the development of OPLL. In addition, serial measurements of these parameters might be useful for estimating the progression of OPLL.
