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 ...

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 ...

Additive and global functions of HoxA cluster genes in mesoderm derivatives

Denis Duboule, Freddy Radtke, Ute Koch

Hox genes encode transcription factors that play a central role in the specification of regional identities along the anterior to posterior body axis. In the developing mouse embryo, Hox genes from all four genomic clusters are involved in range of develop ...

Changes in Hox genes' structure and function during the evolution of the squamate body plan

Denis Duboule

Hox genes are central to the specification of structures along the anterior-posterior body axis, and modifications in their expression have paralleled the emergence of diversity in vertebrate body plans. Here we describe the genomic organization of Hox clu ...

Scanning and transmission electron microscopy for evaluation of order/disorder in bone structure

Philippe Buffat, Elena Suvorova Buffat

A comparative characterization of the structure of normal and abnormal (osteoporotic) human lumbar and thoracic vertebrae samples was carried out to reveal the type of possible disorder. Samples from the bone fragments extracted during the surgery due to v ...

Analysis of the stability of a posterior fusion system for the treatment of burst fractures

Dominique Pioletti, Arne Christian Vogel, Martin Aeberhard

In the framework of spine traumatology, burst fractures are severe and are often caused by car accidents or by falls. The vertebra breaks under the traumatic compression and pieces of it are shattered in all directions. This type of fracture is often treat ...

Hox gene function in vertebrate gut morphogenesis: the case of the caecum

Denis Duboule, Jozsef Zakany

The digestive tract is made of different subdivisions with various functions. During embryonic development, the developing intestine expresses combinations of Hox genes along its anterior to posterior axis, suggesting a role for these genes in this regiona ...
