Numerical methods such as boundary element and finite element methods are widely used for the stress analysis in solid mechanics. This study presents boundary element method based on the displacement discontinuity formulation to solve general problems of interaction between hydraulic fracturing and discontinuities. The crack tip element and a higher order boundary displacement collocation techn...

BACKGROUND Fracture of the distal radius is a common clinical problem particularly in elderly white women with osteoporosis. OBJECTIVES To determine the most appropriate conservative treatment for fractures of the distal radius in adults. SEARCH STRATEGY We searched the Cochrane Musculoskeletal Injuries Group trials register, MEDLINE, PubMed, CINAHL, CENTRAL (Issue 2, 2000 of The Cochrane L...

The incidence of complications secondary to fracture stabilization, particularly osteolytic lesions and bony tumor formation, has long been difficult to evaluate. The objective of this study was to describe the long-term incidence of aggressive bony changes developing in dogs with long bone diaphyseal fractures stabilized by metallic bone plates compared to a breed-, sex-, and age-matched contr...

OBJECTIVE To investigate the injury mechanism in patients who had peroneal neuropathy after a tibio-fibular fracture and the correlation between tibio-fibular fracture location and the severity of the peroneal neuropathy by using electrodiagnosis. METHOD Thirty-four patients with peroneal neuropathy after a tibio-fibular fracture were recruited for this study. Their medical records, radiologi...

fat embolism syndrome is a clinical diagnosis, and diagnostic procedures are not specific. in every trauma patient, fat embolism syndrome has to be considered as a possibility and supportive treatment should begin as soon as possible. the authors reported a rare case of fat embolism syndrome whose only neurological symptom was motor aphasia. a young man sustained comminuted femoral shaft fractu...

Between January 2005 and May 2009, a total of 26 patients, 21 males and 5 females, were admitted for treatment of Lisfranc lesion. All patients were radiologically evaluated and classified according to the criteria proposed by Myerson: 5 (19.2%) patients had a type A injury, 2 patients (7.7%) presented with a type B1 injury, 17 (65.4%) sustained the most common type B2 injury and 1 (3.8%) patie...

BACKGROUND Treatment intervention thresholds for prevention of osteoporotic fractures can be derived from reports from the World Health Organization (diagnostic criteria) and National Osteoporosis Foundation (treatment criteria). It is not known how well these thresholds work to identify women who will fracture and are therefore candidates for treatment interventions. We used data from the Nati...

BACKGROUND Studies comparing internally linked (person-identifying) and unlinked (episodes of care) hospital discharge data (HDD) on hip fractures have mainly focused on incidence overestimation by unlinked HDD, but little is known about the impact of overestimation on patient profiles such as comorbidity estimates. In view of the continuing use of unlinked HDD in hip fracture research and the ...

Correction After the publication of this abstract [1], we found some mistakes in the text. In details: Methods section: the correct sentence is “We modified these protocol improving screening criteria to all patients with petrous bone fracture, even without carotid canal involvement”. Results section: the correct sentence is “According to our proposed modified Memphis criteria, 53 patients (ins...

This paper reports a prospective study of 72 consecutive patients with fractures or fracture-dislocations of the upper end of the humerus, treated during 1981. Most were elderly and treatment was conservative. Of the 72 patients 64 were followed up for a period of six months. Observations were made on the type of fracture, the speed and pattern of recovery of shoulder movements, on the time of ...
