Ad. Svindland et al., PERIOSTEAL RESPONSE TO TRANSIENT ISCHEMIA - HISTOLOGICAL STUDIES ON THE RAT TIBIA, Acta orthopaedica Scandinavica, 66(5), 1995, pp. 468-472
Complete arrest of blood flow was induced for 4.5 hours in the left hi
ndlimb of Wistar rats by a tourniquet applied proximally to the thigh.
Histologically the periost of the tibial bone after 3 days showed mar
ked hypertrophy and hyperplasia of the periosteal cells with an osteog
en differentiation. This response is similar to the initial formation
of external callus during fracture healing. Transient ischemia may be
an important factor in initiating fracture healing.
