Comparison of planimetric transilluminational and X-ray densitometric data in the healing of bone defects

We conducted a study of the effect of the thermal factor on the healing of a bone defect. To apply burns to bone tissue, a special device was designed — a thermoidenter consisting of an electrothermometer and a powerful heater with a sting, in which a thermosensitive element — a thermistor was mounted. In the femur of rabbits under thiopental anesthesia, a hole with a diameter of 3.4 mm was drilled with abundant irrigation with saline solution, where the sting of the thermoident was then placed, preheated to the required temperature, and kept in it for the required time. The intervals of the studied parameters were 40-180 ° in temperature, 5-240 s in exposure (t), 0.60 days in regeneration period (T).
