Graphene nanoribbons (GNRs) have received a great deal of attention due to their promise for electronic and optoelectronic applications. Several recent studies have focused on the synthesis of GNRs by the bottom-up approaches that could yield very narrow GNRs with atomically precise edges. One type of GNRs that has received a considerable attention is the chevron-like GNR with a very distinct p...

Exposure of the distal humerus in case of an articular fracture is often performed through a Chevron osteotomy of the olecranon. Several options have been described for re-fixation of the Chevron osteotomy. Pull-out of the hard-wear is often seen as complication. In this study, an evaluation of the re-fixation of the Chevron osteotomy through a cancellous screw and suture tension band was perfo...

They are associated with valgus deviation of the great toe which moves towards the second toe. Hallux valgus is found in at least 2% of children aged 9 to 10 years, and almost half of adults, with greater prevalence in women. METHODS AND OUTCOMES: We conducted a systematic review and ai...

INTRODUCTION This treatment-outcome assessment objectively compares Invisalign (Align Technology, Santa Clara, Calif) treatment with braces. METHODS This study, a retrospective cohort analysis, was conducted in New York, NY, in 2004. Records from 2 groups of 48 patients (Invisalign and braces groups) were evaluated by using methods from the American Board of Orthodontics Phase III examination...

The questionnaire contained the following six questions: 1. What instrument do you play? 2. How long did you play it before you had braces? 3. How did braces affect the way you played your instrument? 4. How long did it take you to get used to playing your instrument with braces? 5. Did any specific aids (examples: wax, brace guard, etc.) help you get used to playing your instrument with braces...

Introduction There are a wide variety of brace applications available today with different outcomes and different characteristics. The purpose of this study is to compare in-brace corrections of the series applied today to recent Chêneau series braces as presented in literature. methodology All patients were registered and fulfil the Scoliosis Research Society inclusion criteria for studies on ...

Braces are commonly used for the management of musculoskeletal injuries. With improvements in design and application, the knee brace has gained recognition by many as a treatment and prevention modality. However, there exist many different categories of knee braces, leading to confusion among many end users. The theoretical basis of the mechanism of action of the unloader, prophylactic, patello...

Braces today are named according to the author's name or town. The existing classification of braces considers only the anatomical spinal section involved (C: cervical; T: thoracic; L: lumbar; S: sacral; Orthosis). The absence of a more detailed classification do not allow to really distinguish between the different braces and to have a common language between the conservative treatment experts...
