The use of the Söring bone instrument leads to significantly less heat development on the bone than the use of a high-speed drill. This is the result of a single-blinded prospective randomized controlled study conducted at the department of neurosurgery at the University Medicine Greifswald.

In this study the authors examined Söring’s bone instrument compared to a high-speed drill in terms of heat generation during bony decompression of lumbar spinal stenosis. A low temperature plays an important role for the preservation of nerves and vessels as well as for the viability of the bone. Burns can lead to irreversible damage and slower healing of the bone.

"The temperature development when using the Söring bone instrument is lower than with the high-speed drill. In addition to the technology-related selectivity, this reduces the risk of damaging neurovascular structures," says Dr Jan-Uwe Müller, deputy director of the department of neurosurgery at the University Medicine Greifswald, summarizing the results.

This first study on the ultrasonic-assisted Söring bone instrument was recently published online in the renowned magazine World Neurosurgery (2018, 111: e72-e81). We have summarized the main results of the study in a one-pager, which you can request here.
