Abstract Cortical bone is semi-brittle and anisotropic, that brings a challenge to suppress vibration avoid undesired fracture in precise cutting process surgeries. In this paper, novel analytical model proposed represent cortical processes. The utilized predict the chip formations, material removal behavior cracks propagation under varying osteon angles depths. Series of orthogonal experiments...

The piezosurgery has been used with increasing frequency and applicability by health professionals, especially those who deal with dental implants. The concept of piezoelectricity has emerged in the nineteenth century, but it was applied in oral surgery from 1988 by Tomaso Vercellotti. It consists of an ultrasonic device able to cut mineralized bone tissue, without injuring the adjacent soft ti...

Distal fibula fractures are the most common injury of weight bearing bones. Several studies have shown the benefit of locking plates especially in osteoporotic bone. The aim of this biomechanical study was to test the anatomically shaped VariAx Distal Lateral Fibula Plate in comparison to a commonly used 1/3 Tubular Plate. The implants were assembled to bone surrogates simulating a comminuted f...

Since the cancellous bone displays a fluid-solid coupled porous structure, its solid matrix exhibits excellent osteogenic property and has been extensively used as the scaffold material of tissue-engineering bone. It is the aim of the present paper to examine the transversely isotropic behavior of cancellous bone. Correspondingly, a two-dimension image analysis method was developed to determine...

he mid-frontobasal approach can be carried out with the help of several tools, thanks to the technical improvements in the neurosurgical field. Cutting thick bone is one of the drawbacks of the power saw, this needs rongeuring of the bone or the use of manual spiral wire with handle.1 The use of the Gigli saw2 requires additional time compared with power-driven drills, however, this is amply co...

OBJECTIVES Because of the contradictory body of evidence related to the potential benefits of helical blades in trochanteric fracture fixation, we studied the effect of bone compaction resulting from the insertion of a proximal femoral nail anti-rotation (PFNA). METHODS We developed a subject-specific computational model of a trochanteric fracture (31-A2 in the AO classification) with lack of...
