Correct diagnosis of vertical root fractures is in most cases difficult because of lack of specific symptoms and signs, and/or radiological conclusive aspects; therefore, the differential diagnosis with other pathological entities can be challenging. The purpose of this study is to evaluate, clinically and radiologically, a number of 35 teeth with vertical root fracture. For early identification of vertical root fracture, should be carefully combined the reason of patient presentation, clinical examination and rigorous interpretation of radiographs (periapical, bitewing and CBCT if necesary). Diagnosis of vertical root fracture is based on some subjective parameters; is important to recognize at an early stage vertical root fracture and to inform the patient, to recive adequate information about proper treatment. Vertical root fracture can sometimes be difficult to distinguish from incorrect endodontic treatments or some periapical pathology; vertical root fracture is the main cause of extraction of endodontic treated teeth.

Aim. Segmental bone defects of the tibia after high-energy trauma are limb-threatening conditions. Multiple treatment options have been proposed, including nonvascularized bone grafts, vascularized bone transfers, and callus distraction. A series of 4 patients with major segmental defects of the tibia treated with vascularized bone reconstruction is presented. Methods. Four chronic segmental bone defects of the tibia, 5 cm or more in length, were included in the series. Reconstruction was performed with double barrel free vascularised fibular graft by a surgical team of orthopaedics and plastic surgeons. Bone fixation was performed with screws and external fixation, with early conversion to locking plate internal fixation. Results. They were not any case of graft lost or infection. Bone healing occurred in all cases. Stress fractures did not occurred. Time to bone union was 5 to 8 months, and time to full weight bearing was 4 to 6 months. Conclusions. The use of vascularized bone transfer in the treatment of major segmental tibial defects was successful in the present series. The management of bone fixation in these cases is discussed. INSET: 93.

We present a transversal study in 306 anti-osteoporotic free medication, postmenopausal women, who were analyzed based on DXA. The 153 patients with osteopenia were statistically significant different from those 103 with normal DXA by following parameters: body mass index, bone formation marker serum osteocalcin, bone resorbtion marker serum CrossLaps. The heel quantitative ultrasound (QUS) analyze by two devices Achilles and Sonost Chrono 3000 revealed differences between the Stiffness index values between osteopenia and each of the other two groups.

Objectives: the study aims to determine the mineral bone loss in ankylosing spondylitis (AS) patients, by eveluating the bone turnover markers and bone mineral density (BMD) and to correlate the results to the main clinical and biological parameters characterising AS. Matherial and methods: we have determined osteocalcin and beta-crosslaps blood concentrations, alongside of clinical, biochemical, radiological parameters as well as lumbar and femural neck BMD, on a sample of 27 patients diagnosed with ankylosing spondylitis. Same parameters have been determined in a sample of 27 healthy men, with similar demographic characteristics. Results: most patients presented high concentrations of bone turnover markers, directly correlated with BMD measured at femural neck and with inflamation markers. Conclusions: ankylosing spondylitis is a condition that is charactherised by both bone mass production and loss, directly correlated with the inflammatory stage of the disease.

The objective of this study was the identification of the therapeutic possibilities for the fractures of the distal humerus type B3.3 - classification AO. In a series of 773 cases of distal humerus fractures, only 5 cases were identified with this type of fracture. In the treatment of this type of fracture the following methods were taken into consideration: open reduction and internal fixation with Herbert screws in 3 cases; arthroplastic resection in one case and a conservatory treatment (upon request) in one case - this latter case was subsequently excluded for failure to show up. Given the very small number of cases recorded, no solid conclusions could be drawn from the results obtained. However, the data support the following assertions: the arthroplastic resection remains a solution to consider when the possibilities of fixation are out of the question, the great inconvenient of this procedure being the residual instability; the internal fixation with Herbert screws is the method of choice because the fixation with plate according to the AO recommendations is often impracticable [ABSTRACT FROM AUTHOR]

The purpose of this study is to determine a relation between wine consumption and bones structure, especially the relation with the complexity of the fracture trajectories. As we have shown in our previous articles, in wine chemical composition there are a series of metabolically active compounds, especially at vascular level. Therefore, there is a higher probability that at least a part of these compounds influence, in one way or another, the stage of vascular invasion of the fibrous callus. This study included a number of 121 cases who came at the emergency service with fractures at the level of the inferior extremity of the radius. To quantify the fracture trajectory and the degree of displacement of the fragments, the Kapadnji classification (1988) was used, which divides the fractures of the distal extremities of the radius in 12 types. We observed that the frequency of simple fractures is higher in the cases who declared to be wine consumers, which leads to the idea that bone resistance is higher among this population.

In order to evaluate the functional results, 32 cases with surgical treatment were followed, namely 19 in which the open reduction and Herbert screws fixation was attempted and 13 in which the excision of fragments was conducted. All the cases in which the excision was used showed instability, while instability was identified in only one case of osteosynthesis. The cases in which excision was used showed a clearly inferior evolution as compared to those in which osteosynthesis was used. The deterioration of the MAYO score for the cases in which excision was used is due mainly to residual instability [ABSTRACT FROM AUTHOR]
