Our initial concept and technique over many years have remained unchanged purchase 200 mg nizoral overnight delivery. We have studied and looked into the problems of biological ﬁxation with the goal of improving our long-term results in hip joint replacement buy 200mg nizoral overnight delivery. Still generic nizoral 200mg without prescription, we must consider the relative merits of cemented and cementless technique for each patient, but in the case of the cementless primary hip replacement, proximal load transfer and high axial and rotational stability were deﬁned as the key charac- teristics for our “Bicontact”-philosophy. These requirements meanwhile, after 19 years experience, are well accepted today and we use them before many others. We have added to our earlier concepts the methods of contemporary cementing tech- niques, press-ﬁt cup arthroplasty, and advanced hip joint articulation. Implant exten- sions also met additional requirements of implant sizing in primary and revision surgery. We have seen remarkable change within our patient community, with an increase of elderly people—and a more disadvantageous increase of many young patients—receiving total replacement as a ﬁrst and primary choice. This change must lead our attention to an individual decision, that is, whether to select the cemented or noncemented technique, which choice quite often has to be made intraoperatively. The Bicontact Hip System fulﬁlls all these aspects and thus justiﬁes the catalogue of requirements we initially have laid down. After more than 19 years of Bicontact hip replacement, a statement on the correct- ness of our considerations relating to design and performance of the entire Bicontact philosophy can be made. This self-critical appraisal is based on the experiences of our own prospective study results, other published Bicontact results, and multiple worldwide experience reports. Many constructive thoughts and developments in the ﬁeld of hip arthroplasty have been communicated, implemented, and introduced in clinical practice during the last few decades (46 years since Charnley). In many respects, these have resulted in visible and fundamental improvements concerning basic implant design, materials, and clinical results [4–10]. The cemented ﬁxation of the prosthetic components introduced by Charnley (1959/1960) with his low-friction principle of the joint implant had a fundamental inﬂuence and promoted its growing use in clinical medicine.
Flipchart Flipcharts buy nizoral 200mg line, like whiteboards generic 200mg nizoral free shipping, are very useful as notepads for workshop or seminar discussions generic nizoral 200mg with visa. The sheets tear off, making them ideal for use in re cording group discussions like brainstorms. Unlike the whiteboard the sheets can be retained for reference later in the seminar. When using flipchart sheets remember to: ° Check that all the students have a clear view of the flipchart. Either mask with paper or leave blank pages in between your prepared sheets. PREPARING MATERIALS FOR TEACHING 149 ° Fold back sheets rather than tearing them off, as you may need to refer to them later. Start writing or drawing about a third of the way in so your body is not obstructing the audience’s view. Use the first two thirds of the chart (the part furthest away from you). These are handy for preparing material in advance, but their small size restricts their use to groups of ten or less. Some are designed for use in preparing for a session, for example a list of preparatory reading or a document containing introductory material. Many are for use during the session, for example a gapped handout to be completed by the student during the lecture, while others are to promote further individual study by the student after the session, for example a reading list. Use handouts to: ° provide preparatory reading, for example background information, glossary of terms or ‘stop and think’ activities ° provide complex information such as detailed numerical data or diagrams ° give evidence in support of the main arguments, for example research studies, detailed case studies and explanations ° aid note-taking by supplying copies of essential acetates or illustrations ° encourage active listening by supplying gapped handouts to be completed during the lecture, for example labelling a diagram or filling in key terms ° encourage self-assessment by using true/false or multiple-choice questionnaires 150 WRITING SKILLS IN PRACTICE ° facilitate learning activities, for example instructions for practical tasks, data sets and case studies for problem solving ° give students the opportunity to apply new concepts or principles, for example analysing data sets ° promote further study by giving lists of references, further reading or a set of questions to focus students’ reading and note-taking. When using handouts remember to: ° Decide on a system for distribution as giving out paper to a large group is time-consuming and may disrupt the flow of your presentation. Some ideas are to: ° Place handouts on chairs before the audience arrives. PREPARING MATERIALS FOR TEACHING 151 Evaluation Monitor the cost-effectiveness and efficacy of your teaching materials. Summary Points ° Additional written materials, such as acetates, slides, flipcharts or handouts, are used to support teaching.
