Connexin 43 Modulation in Human Chondrocytes, Osteoblasts and Cartilage Explants: Implications for Inflammatory Joint Disorders.

Connexin 43 (Cx43) is crucial for the development and homeostasis of the musculoskeletal system, where it plays multifaceted roles, including intercellular communication, transcriptional regulation and influencing osteogenesis and chondrogenesis. Here, we investigated Cx43 modulation mediated by inflammatory stimuli involved in osteoarthritis, i.e.

[Maxillary distraction and implantology].

Vertical alveolar distraction can be a useful surgical technique in preprosthetic reconstructive surgery, especially after failed autogenous onlay bone grafting. The main advantage of this technique is to allow expansion of both the bone and soft tissue. Through a case of vertical alveolar reconstruction by distraction osteogenesis and implant rehabilitation in a patient who had undergone two previously unsuccessful interposition bone graft procedures, this report illustrate the advantages of alveolar ridge augmentation by distraction osteogenesis.

[The retromandibular approach in fractures of the mandibular condyle].

Various approaches have been proposed for surgical treatment of displaced condylar fractures included submandibular approach, preauricular approach, rhytidectomy approach or intraoral approach. Since 1992, we used a short retromandibular approach to treat displaced subcondylar fractures with a miniplate. When open reduction and osteosynthesis are required, the retro-mandibular approach is an easy and safe technique for displaced condylar fractures.
