The Importance of Periostal Circulation After Osteosynthesis with Plates and Screws

The function of periosteum presents an important clinical and sciencitific interest in the process of bone healing. Today, we know much more about phy siological, histological and biochemical process that happen in the fractured tissue. Our aims were: to quantify microcirculation of the intact periosteum ; to quantify the microcirculation of the periosteum after osteosynthesis with plates and screws ; to use our result for the construction of the new plate, with decreased damage to periosteum. In our investigatiog we used sheep. The plate was implanted on sheep tibia, supraperiostaly on the intact bone. Contralateral leg was used as the control group (without plates). Our results show that periostal circulation seems to be very sensitive to compression caused by plate implantation (number of capillares in damaged tissue is almost double less than in normal, 43%, what is statistically significant).
