A wide range of orthopedic, cardiothoracic, neurological, and maxillofacial procedures requires that the bone be cut or resected, either to operate on the osseous tissue itself or to gain access to other organs. As any living tissue, bone bleeds when cut or fractured, and to reduce the risk of post-operative complications, bone bleeding needs to be managed during surgery. The present chapter ex...

The aim of this study was to compare the peripheral bone damage induced by different cutting systems. Four devices were tested: Er:YAG laser (2.94 mm), Piezosurgery, high-speed drill and low-speed drill. Forty-five bone sections, divided into 9 groups according to different parameters, were taken from pig mandibles within 1 h post mortem. Specimens were fixed in 10% buffered formalin, decalcifi...

We assessed the hydration state of antlers and its effect on antler mechanical properties compared with wet femur. Red deer antlers were removed from the head at various times, from a few days after velvet shedding till late in the season, and weighed weekly until after casting time. Antlers cut just after losing their velvet lost weight rapidly in the first few weeks, then settled down and cha...

Although 2-dimensional assessments using postoperative plain radiographs have been used after total knee arthroplasty (TKA) in previous studies, a strong possibility exists that deviation can occur when assessing 3-dimensional (3-D) objects. The purpose of this study was to test the hypothesis that novel 3-D image-matching software could accurately assess the positioning of implants and could b...

OBJECTIVE The aim of this study was to investigate the predictability of bone density at posterior mandibular implant sites using cone-beam computed tomography (CBCT) intensity values. MATERIALS AND METHODS CBCT cross-sectional images for 436 posterior mandibular implant sites were selected for the study. Using Invivo software (Anatomage, San Jose, California, USA), two observers classified t...

Background: An oscillating bone saw is rarely used to perform laminectomy. The purpose of this study was to describea relatively quick and harmless technique for multilevel laminectomy in patients with lumbar spinal stenosis (LSS) usingan oscillating bone saw to find out how this instrument affects the time of surgery and rate of complications.Methods: This prospective study w...

Abstract The aim of this study was to analyze biomechanically the impact bone cement augmentation on fixation strength and cut-out resistance Proximal Femoral Nail Antirotation (PFNA) Trochanteric Fixation Advanced (TFNA) head elements within femoral in a human cadaveric model with poor quality. Methodology: Fifteen pairs fresh-frozen heads were randomized three sets five each for center-center...

Introduction. Skills training using artificial bones became more critical in response to the Orthopedic surgical restriction caused by COVID-19 pandemic. To cut expenses of buying commercial bones, Ilizarov Limb Reconstruction Service has decided fabricate its for skills training. Objective. determine if resin-coated polyurethane (PU) rigid foam is a suitable, low-cost alternative bone. Metho...

Aseptic loosening of the tibial component is the major complication of total knee arthroplasty. There is an association between early excessive shear micromotion between the bone and the tray of the tibial component and late aseptic loosening. Using non-linear finite element analysis, whether a tibial tray with a circumferentially flanged rim and a mating cut in the proximal tibia could minimiz...
