“…It results from the partial protecting from functional stress afforded to the bone by load sharing with the plate, and is characterized by bone atrophy and reduced strength in the plated bone segment (Uhthoff & Dubuc 1971, Stromberg 1975, Tonino et al 1976.…”

The purpose of the present study was to find the extent of stress-protection by a steel plate (45 X 5 X 1 mm) on the rabbit tibia. The animals were sacrificed after 6, 12 and 18 weeks. The median strength after plate application was 84, 73 and 72%. respectively. The elastic stiffness of plated bones was also reduced, while the deformation at fracture showed no significant reduction. The mineral content in the bone segment previously covered by a plate was measured by photon absorptiometry; it was reduced after 12 and 18 weeks. The stress-protecting effect caused by this thin steel plate was less pronounced than that previously reported by groups using more rigid plates on rabbit tibiae. The stress-protecting effect increased up to 12 weeks, but subsequently no further increase occurred.

“…Whether the observed reduction in biomechanical strength may be counterbalanced by early removal of the implants remains to be seen. Uhthoff & Dubuc (1971) demonstrated histologically a slow recovery of the bone after implant removal. Preliminary data from this laboratory suggest that the bone strength returns to normal at a rate which corresponds to the length of time the implants have been attached to the bone (Joukainen et al 1983).…”
