CONTEXT Mobile water within the bone marrow is a physiological phenomenon that is identifiable on magnetic resonance (MR) imaging, and signal changes can result from blood pooling, reactive hyperemia, edema, and microfracture. When these MR lesions are associated with an acute traumatic event, the findings are referred to as bone bruises and so represent a unique manifestation of injury. This r...

Atraumatic fractures of the skeleton in osteoporotic patients are directly related to a deterioration of bone strength. However, the failure of the bone tissue to withstand functional load bearing cannot be explained as a simple decrease in bone mineral density (quantity); strength is also significantly dependent upon bone quality. While a formal definition of bone quality is somewhat elusive, ...

OBJECTIVE To evaluate the applicability of the WHO densitometric criteria for the diagnosis of spinal osteoporosis in men and to compare it with women with vertebral fractures, as well as to analyze the role of vertebral dimensions in the development of spinal fractures. METHODS For these purposes we analyzed, using DXA, vertebral projected area and lumbar bone mineral density (BMD), as well ...

Aim: The aim of this case report was to reconstruct the alveolar buccal bone plate lost in consequence of a root fracture in the maxillary central incisor area after immediate implant placement (IIP). A 48-year-old patient was referred to our office with the chief complaint of spontaneous bleeding in his left central incisor. After careful examination, the following comprehensive treatment appr...

Spontaneous splenic rupture, also referred to as atraumatic splenic rupture, is a rare but life-threatening emergency condition. Without timely diagnosis and treatment, the mortality rate of splenic rupture approaches 100%. The etiology of atraumatic splenic rupture varies; it is reportedly associated with neoplasms or splenic infection, but is rarely encountered in patients with both condition...

We report the case of a patient with acute exacerbation of chronic pancreatitis and he suffered an atraumatic splenic rupture. Splenic rupture not associated with trauma is a rare entity that can occurs in normal spleen (spontaneous) or damaged spleen (pathological). This entity may be associated with local inflammatory processes, such as pancreatitis. Ultrasound is a non-invasive technique whi...

OBJECTIVES The aims were to overview healing of extraction socket, recommendations for atraumatic tooth extraction, possibilities of post extraction socket bone and soft tissues preservation, augmentation. MATERIALS AND METHODS A search was done in Pubmed on key words in English from 1962 to December 2011. Additionally, last decades different scientific publications, books from reference list...

PURPOSE To describe a new, relatively atraumatic method of cauterizing the maxillary artery and its effectiveness in treating cluster headache. MATERIALS AND METHODS Five patients with cluster headache were treated with arterial ligation of certain terminal branches of the external carotid artery. A new, atraumatic method of cauterizing the maxillary artery is described. RESULTS The success...

The primary objective of the Atraumatic Restorative Treatment (ART) is to reduce the indication of tooth extraction by means of a low-cost technique. Considering the difficulties of Brazilian public services to meet the demand of care of the low-income population, with lack of care to the adult population, which usually receives only emergency care, the aim of this study is to assess the perfor...

Morphological vessel injury after clamping has been an important problem in vascular surgery. Although various techniques have been employed to occlude a vessel during a surgical procedure, a complete, atraumatic occlusion method has not yet been developed. In the present study, we describe use of a novel pressure-controlled and balloon-jawed vessel clamp to provide atraumatic vessel occlusion....
