Flexoelectricity in Bones

Bones generate electricity under pressure, and this electromechanical behavior is thought to be essential for bone’s self-repair and remodeling properties. The origin of this response is attributed to the piezoelectricity of collagen, which is the main str ...

Osteogenesis imperfecta: from diagnosis and multidisciplinary treatment to future perspectives

Dominique Pioletti, Lee Ann Laurent-Applegate

Osteogenesis imperfecta is an inherited connective tissue disorder with wide phenotypic and molecular heterogen- eity. A common issue associated with the molecular ab- normality is a disturbance in bone matrix synthesis and homeostasis inducing bone fragil ...

Surgical Anatomy of the Human Round Window Region: Implication for Cochlear Endoscopy Through the External Auditory Canal

Demetri Psaltis, Simon Nessim Henein

Objective: To enable development of an endoscope for cellular-level optical imaging of the inner ear. Study Design: A prospective study of 50 cadaveric human temporal bones to define detailed surgical anatomy of the round window (RW) region and the range o ...

Muscles in a Shoulder Model: Identification of the necessary number of muscle cables

Jeannette Liniger

The shoulder complex is a complex articulation of the human body. It consists of several bones and joints and is moved and stabilized by 16 muscles. The muscle forces can not be measured experimentally, but can be computed using numerical methods. An exist ...

Pulsatile blood flow in human bone assessed by laser-Doppler flowmetry and the interpretation of photoplethysmographic signals

Dimitri Nestor Alice Van De Ville, Jean-Noël Hyacinthe, Jonas Richiardi

Human bone blood flow, mean blood speed and the number of moving red blood cells were assessed (in arbitrary units), as a function of time, during one cardiac cycle. The measurements were obtained non-invasively on five volunteers by laser-Doppler flowmetr ...

Finite element analysis of knee squat with an osteochondral defect

Ernst Remij

In this work a 3D musculoskeletal model of the knee joint, that can simulate a squat movement, has been developed. Such a model would be useful to understand the biomechanics of the knee. The model consisted of all the the bones with their articular surfac ...

Homeobox genes d11-d13 and a13 control mouse autopod cortical bone and joint formation

Denis Duboule

The molecular mechanisms that govern bone and joint formation are complex, involving an integrated network of signaling pathways and gene regulators. We investigated the role of Hox genes, which are known to specify individual segments of the skeleton, in ...

Finite element analysis of strain distribution in a bone scaffold used with revision knee prosthesis

Line Aschwanden

The goal of this study is to analyze mechanical behavior of a new scaffold composed of PLA/bTCP in revision knee arhtroplasty (RKA). For this purpose, finite element models of RKA was developed to study the importance of the geometry of bones, the fixation ...

Fetal bone cells for tissue engineering

In this thesis, the potential use of fetal bone cells for tissue engineering was evaluated. At first, fetal bone cells were characterized in vitro regarding their proliferation rate, the induction of their osteoblastic phenotype, and their antigenicity. Th ...
