BACKGROUND A neuronavigation interface with extended function as compared with current systems was developed to aid during temporal bone surgery. The interface, named EVADE, updates the prior anatomical image and visualizes the bone drilling process virtually in real-time without need for intra-operative imaging. Furthermore, EVADE continuously calculates the distance from the drill tip to segm...

BACKGROUND Osteoid osteoma is a painful benign osteogenic tumour for which the treatment objective is surgical resection of the nidus. The acetabular fossa is an uncommon site of involvement where surgical access can prove challenging. MATERIALS AND METHODS We report a case-series composed of five patients with osteoid osteoma of the acetabular fossa treated with percutaneous bone resection a...

AIM To assess the efficacy of the far lateral approach, without drilling of the occipital condyle, in the management of anterior intradural tumors at the craniocervical junction. MATERIAL AND METHODS Ten patients suffering from foramen magnum tumors were operated upon via the far lateral approach without drilling of the occipital condyle. All patients underwent postoperative C...

Microdamage reduces bone mechanical properties and thus could possibly contribute to implant failure. The objective of this study was to investigate whether the diameter of mini-implants (MI) affects microdamage generation and whether this differs between the mandible and maxilla due to their contrasting cortical thicknesses. Methods: Maxillary and mandibular quadrants of 5 dogs were randomly a...

BACKGROUND The aim of the present study was to evaluate the relationship between insertion torque and stability of miniscrews in terms of resistance against dislocation, then comparing a self-tapping screw with a self-drilling one. METHODS Insertion torque was measured during placement of 30 self-drilling and 31 self-tapping stainless steel miniscrews (Leone SpA, Sesto Fiorentino, Italy) in s...

In bone cutting, the tissue is exposed to necrosis due temperature elevation, which can significantly influence postoperative results in orthopaedic surgeries. This damage usually revealed through histological analysis show necrotic extent; however, this technique does not capture mechanical damage, essential for a full material integrity assessment. Here, with micro-mechanics, it demonstrated ...
