introduction: distal radius fractures are a common traumatic injury, particularly in the elderly population. in the present study we examined the effectiveness of ultrasound guidance in the reduction of distal radius fractures in adult patients presenting to emergency department (ed). methods: in this prospective case control study, eligible patients were adults older than 18 years who presente...

Trial-by-trial strategy assessments and a microgenetic design were used to examine 4- and 5-year-olds' learning of rules for solving balance scale problems. The design allowed us to examine simultaneously the contribution to rule learning of distal variables (qualities and knowledge with which children enter the learning situation) and proximal variables (processes that they execute during lear...

This paper discusses alternatives to single-step mixture modeling. A 3step method for latent class predictor variables is studied in several different settings including latent class analysis, latent transition analysis, and growth mixture modeling. It is explored under violations of its assumptions such as with direct effects from predictors to latent class indicators. The 3-step method is als...

  Abstract   Background: The tibial diaphyseal fractures are the most common type of long   bone fractures encountered by most orthopedic surgeons. In accordance with descriptive indices of tibia fractures on the basis of their location in the bone, distal tibia   fractures have the second incidence of all tibia fractures after the middle tibia fractures.   The purpose of the study was to asses...

background: here we describe a new case of partial distal 10q trisomy in a 6-year-old iranian girl from healthy parents with mental, growth, and psychomotor retardations. methods: additional clinical features include dysmorphic craniofacial features, microcephaly, bilateral hydronephrosis without heart problems, small and rotated low-set ears, bow-shaped mouth, abnormal teeth, short neck, and a...

anatomically precontoured locking plates are intended to facilitate the fixation of articular fractures and particularly those associated with osteoporosis. fractures of the distal humerus are relatively uncommon injuries where operative intervention can be exceptionally challenging. the distal humeral trochlea provides a very narrow anatomical window through which to pass a fixed-angle locking...

background: root morphology is of utmost importance to endodontic sciences. since there are a few studies on the morphology of mandibular second molars’ roots, and some anatomical variables are not evaluated before, the aim of this study was to investigate thoroughly radicular anatomy of this tooth. materials and methods: this ex vivo study was performed on 150 intact mandibular second molars. ...

Background: Genu valgum usually originates from a deformity of distal femur that is often corrected by distal femoralvarus osteotomy. The osteotomy includes both components of angulationcorrection and translation because the siteof osteotomy is not commonly at the apex of deformity. Improvement of patellar tracking not only depends on valguscorrection, but also it may be partially due to centra...
