We report our experience with the Aesculap Pneumatic Powered Kerrison Rongeur (Aesculap AG Company) Tuttlingen, Germany. ⋯ The new pneumatically powered Kerrison rongeur not only is safe and easy to use but also virtually eliminates the manual fatigue and, at times, pain associated with prolonged bone removal from the use of standard Kerrison rongeurs.

The purpose of this study was to evaluate the clinical outcomes of patients with metastatic thoracic and lumbar tumors after palliative surgery using PTA with posterior instrumentation. ⋯ The PTA with posterior instrumentation for metastatic thoracic and lumbar spinal tumors achieved good surgical results. Palliative surgery for patients with a Tomita's prognostic score of more than 8 may be considered in selected cases, especially in those with ECOG grade III.

The physiologic tremor may cause difficulties in microsurgery, in spite of using armrest. The new (robot hand) technique consists of the I-III finger support, which holds the instruments on Bethlehem (ANDAN BT, Budapest, Hungary) bridge above the operation area, which reduces the tremor at the end of the instruments. ⋯ By this technique, the microsurgical work has become more precise.
