Clinical and morphological aspects of lateral femoral condyle status after an osteochondral fracture. A case report.

Although osteochondral fractures of the lateral femoral condyle are uncommon, fixation of the fragments is recommended, mostly when is about young athletes with such post-traumatic pathology. We present a case of a professional handball player teenager female, with a lateral femur condylar osteochondral fracture after a fall with the right knee in extension and in internal rotation. Magnetic resonance imaging (MRI) showed an osteochondral fracture of the lateral femoral condyle, 34.

Pathological fracture of the femur in a patient with Paget's disease of bone: a case report.

Paget's disease of bone is a benign disease characterized by exaggerated remodeling of the bone matrix after osteoclast-mediated bone destruction. Its etiology is still unknown, despite the fact that it was discovered and described in 1877, but genetic factors and environmental triggers were shown to play their part in the pathogenesis of the disease. The main clinical presentations of the disease are related to bone pain and deformities.

Experimental morphologic and radiologic study of the integration of bone grafts into the host tissue and of the dynamics of the graft-receptor interface.

Bone is the second tissue in terms of number of transplants after blood. There is an increased trend of incidence of severe bone lesions with comminuted fractures, with significant lack of substance, as well as an increased incidence of cancer types combined with therapeutic advances in recent decades, allowing for large surgical interventions that affect the bones and create significant defects in bone and contribute to the overall increase in the number and complexity of bone transplants. Autografts may be used singly or in various combinations, with significantly better effects than other implant materials.

Morphometric analysis of bone vascular channels during the biointegration of autologous bone grafts.

Vascularization of the transplanted bone tissue is a key factor for success and precedes the formation of bone tissue. Vascularized bone grafts have been widely used in bone transplantation for their efficiency. Maturation of the bone tissue at the place of the transplant involves the change in the vascular patterning, from plexiform irregular vascular networks, to regular, polygonal networks following the structure of osteons.

Microdensity and morphometric analysis of autologous bone grafts cells.

Bone transplantation as a mean to reduce the fracture healing time in large defects was attempted for the first time more than 300 years ago, with nowadays several techniques and methods of assessment of its efficacy. The bone graft was longtime thought as initiating the osteogenesis from the recipient, but new data show that cells from the graft contribute to osteogenesis and to its incorporation into newly formed bone. There is no accurate assessment of the microdensity of bone graft cells in evolution so far, the only studies published recently referring to newly formed bone area.
