Background: Alkaline phosphatase (ALP) and bone-specific alkaline phosphatase (BAP) activities may serve as markers of the course and rate of bone healing after sustained fractures. The aim of this study was to examine whether the assessment of BAP as a biochemical parameter in the early posttraumatic phase may indicate the course of fracture healing. To date, the methods used to monitor the bone healing process have been based on the patients' assessment and the radiographic findings. In view of the fact that patient opinion is highly subjective, that the radiographic findings depend on the radiologist's experience and that the monitoring of bone healing is a long-lasting process, measurements of biochemical parameters appear to be the only objective evidence of the changes occurring during bone regeneration. In this study, the activity of bone-specific alkaline phosphatase was measured in the serum of 30 male patients who had sustained facial fractures aged between 20 to 60 years. All patients were treated surgically. The activity of BAP was assessed at day 0, 1, 3, 7, 21, 45 and 90. 90% (n=27) subjects showed positive correlation of gradual increase in BAP values with radiological evidence of bone healing. In the remaining 10% (n=3) there was a decrease in BAP values and correlated with poor or complicated healing. The value of callus correlates with the level of BAP. Results of the present study lead us to the conclusion that by monitoring BAP, one can predict the dynamics of bone healing. © 2016, Datta Meghe Institute of Medical Sciences Deemed University.
