Computer-designed polyetheretherketone implants versus titanium mesh (± acrylic cement) in alloplastic cranioplasty: a retrospective single-surgeon, single-center study.

Background: Polyetheretherketone (PEEK) has emerged as one of the most promising alloplastic materials for calvarial reconstruction because of a number of desirable qualities including resistance to heat and ionizing radiation, biocompatibility, biomechanically similar to native bone, and being nonferromagnetic for postoperative monitoring. We aimed to evaluate and compare the outcomes of alloplastic cranioplasty performed with PEEK, titanium mesh only (Ti-only), and titanium mesh with acrylic cement (Ti-AC); titanium mesh has previously recorded many successes with low complication rates.

Methods: A retrospective, single-surgeon, single-center study for alloplastic cranioplasties was performed between January 2008 and December 2012.

Validating the use of smartphone-based accelerometers for performance assessment in a simulated neurosurgical task.

Background: Reductions in working hours affect training opportunities for surgeons. Surgical simulation is increasingly proposed to help bridge the resultant training gap. For simulation training to translate effectively into the operating theater, acquisition of technical proficiency must be objectively assessed.
