Prefabricated customized cranioplasty implants are anatomically more accurate than manually shaped acrylic implants but remain costly. The authors describe a new cost-effective technique of producing customized polymethylmethacrylate (PMMA) cranioplasty implants with the use of prefabricated 3-dimensional (3D) printed molds. ⋯ Making customized PMMA cranioplasty implants via 3D printed polylactic acid molds is a cost-effective technique for delayed reconstruction of various cranial defects.

We sought to report the operative techniques of the endoscopic supracerebellar transtentorial approach (ESTA) to the atrium of the lateral ventricle, especially focusing on the role of the endoscope and analyzing optically related issues. ⋯ ESTA is an alternative route to the atrium of the lateral ventricle. However, the collateral sulcus, which is highly relied on in neuronavigation, is illegible in the limited area. And the visual field deficit remains the primary challenge with this approach.

To present our experience with anterior transthoracic surgery for high-risk thoracic disc herniations (TDHs) using motor evoked potential monitoring (MEPm). ⋯ Maximal TDH AP diameter, SCO, SCC, (sub)total calcification, and ISC correlate with lower extremity MEP signal deterioration. In experienced hands, TMD with MEPm support is a safe, efficient procedure for high-risk TDHs.

The objective of this study was to investigate the effect of single-level disc degeneration on dynamic response of the whole lumbar spine to vertical whole body vibration that is typically present when driving vehicles. ⋯ The results indicated that single-level disc degeneration can alter vibration characteristics of the whole lumbar spine especially for the degenerated disc level, and increasing the degeneration did not deteriorate the effect of vertical vibration on the spine.
