[Alkaline phosphatase of granulocytes in open fractures of the long tubular bones].

Investigations carried out in 60 patients with open fractures of long tubular bones in osteosynthesis with the Ilizarov apparatus indicated that alkaline phosphatase (AP) of granulocytes fully reflects the postoperative course. 10--24 hours following the trauma the level of AP in patients with grave injuries exceeds that in patients with slight ones. The differences are found to be reliable from the 1st to the 5th day after the injury.
