Surgical approaches to the capitellum: a comparative anatomic study

Alexandre Terrier, Patrick Goetti, Frédéric Vauclair

Background: Osteochondritis dissecans (OCD) of the humeral capitellum is an important cause of elbow disability in young athletes. Large and unstable lesions sometimes require joint reconstruction with osteochondral autograft. Several approaches have been ...

Mimicking Loading-Induced Cartilage Self-Heating in Vitro Promotes Matrix Formation in Chondrocyte-Laden Constructs with Different Mechanical Properties

Dominique Pioletti, Peyman Karami, Naser Nasrollahzadeh Mamaghani, Theofanis Stampoultzis, Yanheng Guo

Articular cartilage presents a mechanically sensitive tissue. Chondrocytes, the sole cell type residing in the tissue, perceive and react to physical cues as signals that significantly modulate their behavior. Hyaline cartilage is a connective tissue with ...

Enrichment of immobile elements in synmagmatic fractures

Alexandra Roma Larisa Kushnir, Michael Heap

Useful minerals containing rare Earth elements (REE) and metals are sourced from magma bodies, but exactly how these elements initially leave the magma is not well known. Here we present textural and chemical analyses of mineral-filled fracture bands withi ...

What are you synching about? Emerging complexity of Notch signaling in the segmentation clock

Andrew Charles Oates, Olivier François Venzin

The Segmentation clock is a population of cellular genetic oscillators, located in the posterior of the elongating vertebrate embryo, that governs the rhythmic and sequential segmentation of the body axis into somites. Somites are blocks of cells that give ...

Patterning and mechanics of somite boundaries in zebrafish embryos

Andrew Charles Oates, Sundar Ram Naganathan

The body axis of vertebrates is subdivided into repetitive compartments called somites, which give rise primarily to the segmented architecture of the musculoskeletal system in the adult body. Somites form in a sequential and rhythmic manner in embryos and ...

Statistical Shape Model for robotic spine surgery

Charles Baur, Marine Chantal Elisabeth Geneviève Clogenson

The goal of the project is to generate a 3D model of the C2 cervical vertebra for surgery planning using an atlas-based segmentation technique. A Statistical Shape Model of the C2 vertebra has been created from 91 CT scans using Statismo [1], a toolkit for ...

Polarity establishment, asymmetric division and segregation of fate determinants in early C. elegans embryos

Pierre Gönczy

Polarity establishment, asymmetric division, and acquisition of cell fates are critical steps during earlydevelopment. In this review, we discuss processes that set up the embryonic axes, with an emphasis onpolarity establishment and asymmetric division. W ...

In vitro quantification of the performance of model-based mono-planar and bi-planar fluoroscopy for 3D joint kinematics estimation

Arnaud Barré

Model-based mono-planar and bi-planar 3D fluoroscopy methods can quantify intact joints kinematics with performance/cost trade-off. The aim of this study was to compare the performances of mono- and bi-planar setups to a marker-based gold-standard, during ...

An Actuated Transfemoral Prosthesis with Optimized Polycentric Knee Joint

Serge Pfeifer

Powered transfemoral prostheses can give above-knee amputees more flexibility than passive devices, for example allowing them to ascend and descend stairs more easily, or allowing a more natural and symmetrical gait pattern. To achieve the high torques req ...

Cement distribution in vertebroplasties: imaging and simulation

Vincent Stadelmann

Prophylactic vertebroplasty, the percutaneous injection of bone cement into a weak vertebral body (VB), has been shown to reinforce the bone and possibly to minimize fracture risks. Cement leakage is still a common occurrence that can cause severe complica ...
