Overhead projector An overhead projector purchase nexium 40 mg with amex, or OHP discount nexium 20mg without a prescription, projects written or printed images from acetate sheets onto a screen in an enlarged form trusted 40mg nexium. Acetates are easy to prepare and are useful for displaying numerical information as well as text. These may be pre-prepared or handwritten straight onto the acetate during a teaching session. The main consideration when using an OHP is that there is a limit to the amount of information that can be clearly portrayed at any one time. Too much text means having to use smaller print in order to fit it onto the PREPARING MATERIALS FOR TEACHING 145 acetate. This will be difficult to read from a distance and requires more time for students to assimilate all the details. It is therefore important when preparing acetates that you make text legible and restrict the amount of data. When preparing your acetates remember to: ° Limit text to a maximum of six to ten lines. Only put letters in capitals when labelling graphics or where there is a mixture of letters and numerals. When using an overhead projector remember to: ° Check that the projected image is in focus and is visible from the back of the room. This helps to focus the audience’s attention and controls the pace of the presentation. This technique can be used to build up a complex overhead from two or three simple ones. Alternatively you can slide your acetate under the roll of acetate on the machine and write on this. Always know where you put your last acetate, and where to get the next one. Filing acetates in a ring binder is one of the most effective ways of keeping them tidy. Slide projector A slide projector, like the OHP, projects images onto a screen. Slides are the source of the image, rather than an acetate, and are particularly useful for portraying certain material, for example histology slides. They are prefera ble to the OHP when lecturing to an audience of 50 or more students. When preparing your slides remember to: ° Limit text to a maximum of six to ten lines. Only put letters in capitals when labelling graphics or where there is a mixture of letters and numerals. PREPARING MATERIALS FOR TEACHING 147 ° Blue on white is probably the best choice if you have a large number of slides to show.

He spoke of there being a 115 Who’s Who in Orthopedics regional orthopedics with its central orthopedic hospital, satellite clinics and uniﬁed staff. During the First World War he was prevented from serving overseas by the effects of a serious chest injury, the result of a motor cycle accident. However, he was placed in charge of the ortho- pedic division of a military hospital in Oxford, which rapidly developed until there were some 400 beds under his care. At this time, the Wing- ﬁeld Convalescent Home was an old-fashioned institution in the neighboring village of Heading- ton; thanks to Robert Jones, Girdlestone was later able to take charge of some army huts, which were erected in the grounds of this convalescent home. In 1919 the Wingﬁeld Hospital, to give it its new name, came under the Ministry of Pensions, but provision was made for crippled children to be treated in one of its wards. In 1922, the whole hospital was transferred by the Ministry Gathorne Robert to the Wingﬁeld Committee and Girdlestone was GIRDLESTONE thus provided with the instrument which, until the end of his life, he wielded with such astonishing 1881–1950 success. Immediately after the war, Robert Jones and his Gathorne Robert Girdlestone was the son of staunch disciple launched their campaign for the the Rev. Girdlestone, Honorary Canon of establishment of regional orthopedic services, and Christ Church, Oxford. He was born in 1881 and in 1920 they organized the Central Council for the was educated at Charterhouse, at New College, Care of Cripples, of which Girdlestone was for Oxford, and at St. Thomas’ he settled in own experience in the three counties of Oxford- Shropshire at Oswestry and there came under the shire, Berkshire and Buckinghamshire was such inﬂuence of Sir Robert Jones, an inﬂuence that that he was able to write with authority on how a was destined to shape the whole of his career.

This conclusion is especially true for large and ﬂoating bucket-handle lesions of a degenerated labrum (Fig generic 20mg nexium fast delivery. We further learned over the years that acetabular dysplasia is not uniform antero- lateral insufﬁciency of coverage of the femoral head but shows a multitude of pure and combined anterior discount nexium 20 mg online, lateral effective nexium 40 mg, and posterior dysplasias. Li and Ganz showed that one of six dysplastic hips were retroverted (Fig. Although the classic anterolateral dysplasia remains the most common, pure lateral deﬁciency of coverage is rare and the pure posterior deﬁciency is an exception, and then is seen in functional hips of proximal Fig. Intraoperative view of a bucket-handle avulsion of a degenerated labrum (arrow) Fig. AP-pelvic radiograph of the dysplastic acetabulum of an Asian woman shows retroversion of the superior one-third of the acetabulum 154 R. Leunig femoral focal deﬁciency (PFFD) or posttraumatic dysplasia. One important group of a posterior insufﬁciency of coverage or anterior overcoverage consists of hips with Salter or triple osteotomies in childhood in which a correct version of the acetabulum was difﬁcult to establish in the presence of an unossiﬁed acetabular rim. If a retroverted dysplastic acetabulum is redirected in the same way as an antero- laterally dysplastic acetabulum, the problem of this hip may be increased and further treatment even more difﬁcult. The acetabulum is extremely retroverted (arrows show the anterior border; the posterior border is hidden behind the inner acetabular wall). On the femoral side the head is deformed, the neck is short, and there is subtrochanteric abduction with medialization of the femoral shaft. The hip showed impingement with 40° ﬂexion, creating severe problems with sitting on a chair. To bridge the displacement necessary for such a correction, the plate had to be prebended stepwise. Fixation was then only possible on the inside of the stable ilium and on the outside of the acetabular fragment. On the femoral side, femoral neck lengthening, trochanteric advancement, and subtrochanteric alignment were necessary to regain an anatomical morphology Periacetabular Osteotomy in Treatment of Hip Dysplasia 155 Our ﬁrst 75 cases with a minimum of 10 years’ follow-up (10–13. Taking all hips, the success rate dropped to 73% with good or excellent results. The higher early failure rate was in the group with grade III osteoarthritis, an observation that caused us to exclude most of such hips from the indication for a reorientation.
I liked going to the supermarket generic 20mg nexium overnight delivery, because you can hold onto the cart and walk around generic nexium 20 mg with amex. I traded it in for that old bus [a minivan] and got a little crane to lift the cart cheap nexium 40 mg with amex. Edith Leder, a physical therapist, echoes Louisa’s comments, saying “walking isn’t really the most important thing most people do. It’s really an asset to me, because I suffer with my balance and my walking, my gait, they call it. Jody Farr had danced around using a wheelchair for years: “It’s deﬁnitely a decision you have to come to yourself. She refused and continued walking until a bad fall hospitalized her for a week, followed by two weeks on the rehabilitation unit. Warren, who was my senior colleague and treated me like gold, really wanted me to stop walking. I would not do that just for him, though, as good as he was to me, a father ﬁgure. A wheelchair is an invalid thing, and I couldn’t manage pushing it myself. The guy from the medical supply store wanted to just drop off this wheelchair one afternoon, and I said, ‘Wait, I’m not sure that I want this. Farr has used a scooter ever since, although she has a manual wheelchair for airplane travel. Nelda Norton’s mother had used a wheelchair before she died, so they had one at home. He uses all his energy in the air- port just trying to get to the plane. These fears are ironic given that today’s wheelchair technologies increase independence and control. Perhaps the contradiction arises from differing frames of reference: a focus on speciﬁc physical losses or on the whole per- son. People who fear dependence often emphasize their psychic determina- tion to endure and push on. The interviews suggest that this frame of reference ﬂips at some point, prompted by increasing physical debility or frustration with existing limi- tations.
