Ossification involves the conversion of other types of connective tissue into bone and can be subdivided based on the precursor tissue type. Ossification from a primitive connective tissue template, termed mesenchyme, is referred to as intramembranous or periosteal ossification. Alternatively, bone formed...
The development of ossification centres in the membranous occipital squama is described, based on observations on human fetal skulls. The interparietal par... G Matsumura,T Uchiumi,K Kida,... - 《Journal of Anatomy》 被引量: 68发表: 1993年 FURTHER OBSERVATIONS ON THE FRACTURED DISTAL RADIAL ...
Heterotopic ossification is formation of mature lamellar bone in soft tissue and is often associated with traumatic injuries 1. It was first described in 1692 by Patin in children with myositis ossificans progressive 2. Based on a hypothetical etiopathogenetic mechanism, several terms have been used...
While surgical excision may provide palliation, the procedure is often burdened with significant intra-operative blood loss due to a more robust contribution of blood supply to the pathologic bone than to native bone. Based on these clinical observations, we set out to examine the role of ...
Once HO has developed to the point that it interferes significantly with the functional capacity of the patient, the only treatment option remaining is surgery, which most commonly is required at the hip. [19] The usual surgical technique used on HO occurring anteriorly at the hip is anterior...
Although a few case reports exist, the radiology literature on this topic is scant. Based on our experience, this entity is under-recognized on imaging studies and often results in diagnostic confusion due to its resemblance to other pathologies such as barium leak and extraskeletal bone-forming ...
Ossification continues toward one or both ends of the diaphysis, but a layer of cartilage (the metaphysis) persists until elongation is finished (this timing differs within and between different bones; see the upcoming section on epiphyseal fusion). This plate of cartilage is often called the ...
A novel skull clamp positioning system and technique for posterior cervical surgery: clinical impact on cervical sagittal alignment. A prospective radiographic study.The purpose of this study was to analyze whether a novel skull clamp positioning system and technique is useful for obtain... Nodoka,Man...
Based on the above findings, we deduce that the impaired osteogenic differentiation abilities of periodontal ligament cells may be a consequence of S100A4 elevation in periodontitis. In conclusion, the results of this study that S100A4 is upreg- ulated in experimental periodontitis models and by ...
Bone - Osteogenesis, Ossification, Intramembranous: Bone is formed in the embryo in two general ways. For most bones the general shape is first laid down as a cartilage model, which is then progressively replaced by bone (endochondral bone formation). A
