a 3-year-old arabian colt was presented for a major gingiva wound at the right rostral part of mandible. after clinical assessments, rostral mandibular fracture was determined. stabilization of fractured region was achieved via cerclage wire application under general anesthesia. fixation wires were left in place for 6 weeks. a 3 -month follow up revealed complete fracture healing. the purpose o...

absractall perilunate fracture-dislocations combine bone avulsions, ligament disruptionand fractures in different forms. the most frequent pattern is the dorsal transscaphoidperilunate fracture-dislocation. the reported risk of missed initial diagnosisin perilunate dislocations is as high as 20%. concerning pathomechanics of theperilunate fracture-dislocation, it should be noted that most dorsa...

introduction: the aim of the present study was to compare hand stainless steel k-files and nickel-titanium profile 0.04 taper 29 series rotary instruments for their efficiency, procedural errors and time consumed in preparation of root canal system. materials and methods: a total of 46 maxillary and mandibular first premolars extracted for orthodontic purposes were collected (two contralateral ...

Osteoporosis is a disease in which the density and quality of bone are reduced, leading to weakness of the skeleton and increased risk of fracture. Osteoporosis literally means "porous bone". When a bone has become osteoporotic or osteopenic (low bone mass), the risk of a fracture increases. The forearm, spine and hip are the most common fracture sites, accounting for more than 80 percent of al...

The Habanero 1 and 3 doublet is the major component in the original electricity generation plan for the Geodynamics geothermal project in the Cooper Basin of South Australia. Various heat extraction studies have been conducted using simplified models such as a single fracture connecting the two wells or an equivalent porous medium representing the reservoir. In our approach, a more realistic fr...

In this paper the Discrete Element Model (DEM) ‘ESyS_Particle’, previously used to model fracture of brittle rocks and earthquake processes, is further developed to be able to be applied to the hydraulic fracturing process in Engineered Geothermal Systems (EGS). The advantage of DEM is that large deformations and dynamic process can be modelled easily. ESyS_Particle has been used to successfull...

BACKGROUND The aim of the study was to refine current evaluation systems used to assess outcome after a hip fracture and to devise a simple and practical system to assess all hip fracture patients. METHODS Three continuous scales were defined for pain, mobility and functional independence. These were all found to have an acceptable degree of inter-observer agreement. The pre-fracture mobility...

INTRODUCTION We report the case of an unusual combination of concomitant subcapital and intertrochanteric fractures of the hip in a patient after a motorcycle accident. To the best of our knowledge, there is no previous report in the literature of these conditions as a result of high energy trauma or of the treatment used. CASE PRESENTATION A 36-year-old Caucasian man was admitted with this r...

statement of problem: endodontically treated teeth are more prone to fracture. the post and core are often used to provide the necessary retention for prosthetic rehabilitation. objectives: the purpose of this study was to: 1) compare the fracture strength of endodontically treated teeth restored either with nickel-chromium (ni- cr) post or non- precious gold-color alloy (npg) post compared to ...
