abstract

background:  distal femur wedge osteotomies for varus or valgus alignment of the lower extremity could be done in either uniplanar or biplanar fashion.:union: time and stability of the osteotomy site has been considered important in this anatomic region. in this study, clinical and radiographic findings of biplane distal femur osteotomy were reported. methods: clinical, functional, and radiological findings of eight patients (10 knees)underwent biplane distal femur osteotomy were evaluated. visual analogue score (vas) and lysholm-tegner knee score were used for the assessment of pain and function before and three months after surgery. results:  in this study, eight patients were included. all patients were female. the mean age was 28±6.3. the mean pre-operativemechanical anglewas 8.7±2.2˚and the post-operativeangle was 1.4±0.53˚ in patients with valgus alignment whileit was 7.0±1.0˚preoperatively and 0.66±1.2˚ postoperatively in patients with varus alignment. the mean lateral distal femoral angle (ldfa)was 85±8.0˚ before surgery and was 88±1.3˚ after surgery. according to lysholm- tegner knee score, in the post-operative visit, sixknees were good and four were excellent. the mean :union: time was 9.2±2.3 weeks.   conclusions:  biplane distal femur osteotomy is a reliable technique that creates larger surfaces and more stability at the osteotomy site with further rapid :union:.

Single Cut Distal Femoral Varus Osteotomy (SCFO): A Preliminary Study

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...

the effect of consciousness raising (c-r) on the reduction of translational errors: a case study

در دوره های آموزش ترجمه استادان بیشتر سعی دارند دانشجویان را با انواع متون آشنا سازند، درحالی که کمتر به خطاهای مکرر آنان در متن ترجمه شده می پردازند. اهمیت تحقیق حاضر مبنی بر ارتکاب مکرر خطاهای ترجمانی حتی بعد از گذراندن دوره های تخصصی ترجمه از سوی دانشجویان است. هدف از آن تاکید بر خطاهای رایج میان دانشجویان مترجمی و کاهش این خطاها با افزایش آگاهی و هوشیاری دانشجویان از بروز آنها است.از آنجا ک...
