[Osteotomy with ultrasound - animal experiments (author's transl)].
In animal experiments with minipigs the SARNS sternum saw and an ultrasonic saw were compared. Groups of five animals were sacrificed after three months and the sterna were examined radiologically and pathoanatomically. A positive hemostyptic effect of the ultrasonic saw, as described in the literature, could be confirmed. Contrary to data in the literature disturbances of bone healing and the extent of tissue lesions in the form of necrosis were considerably more common in the sterna separated with the ultrasonic saw than in the control group.
