Historical vignette

Dan Leksell and Christer E. H. Lindquist

The authors commemorate the life and career of Dr. Ladislau Steiner, one of the world's most highly regarded neurosurgeons, from Stockholm and Charlottesville, Virginia, who has died at age 92. They review the events of Dr. Steiner's early life, including his early training in his native Romania, his escape with his family from East Berlin, and his postgraduate training in neurosurgery at the Karolinska Institute in Stockholm. Dr. Steiner's work in the development of microsurgery and his collaboration with Lars Leksell in the development of Gamma Knife radiosurgery are described. After his retirement from Karolinska, Dr. Steiner had a second career as head of the Lars Leksell Gamma Knife Center at the University of Virginia in Charlottesville. The authors recall their own long association with Dr. Steiner and celebrate his contributions to the field of neurosurgery.

✓ A device is presented that permits several applications for the Leksell stereotaxic system. The patient is fixed in this new system by means of a rectangular instrument that connects to the standard Leksell stereotaxic coordinate frame and maintains spatial orientation after the frame itself is removed. Specific uses for this device include stereotaxic radiosurgery and stereotaxic guidance during microsurgery. Other attractive features of this device are its capability of being precisely reapplied, its compatibility with both computerized tomography and magnetic resonance imaging, and the availability of an accessory device to adapt it for animal stereotaxis.
