central osteophytes in hip osteoarthritis based on the radiographic and anatomical findings ofour patients. In cases where multiple consecutive radiographies fail to reveal the geography ofacetabulum, it is helpful to obtain pre-operative CT-scan especially by the young inexperiencesurgeon. Thus reducing the risk of failure resulting from the interrupted acetabular landmarks.Poster: 59Clinical Results of Reserved v-Shaped High Tibial Corticotomy WuthMinimally Invasive Surgery Without Internal Fixation Devices*Firooz Madadi - Akhtar Hospital - Tehran, Iran*Email: fmedadi@yahoo.comGenu varum is among the most common orthopaedic problems which mostly leads inosteoarthritis. High tibial osteotomy (HTO) is a way for prevention and treating kneeosteoarthritis . Various models of HTO have been proposed and in parallel, HTO-associatedproblems.. The purpose of this study was to investigate the clinical results of a new innovativemethod of HTO named MIS reversed V-shaped high tibial corticotomy in a follow-up period of3-13 years.MethodsBetween 1996 and 2006, 293 patients with medial compartment osteoarthritis and or genuvarum were operated on, using our new method. Patients were examined and interviewed beforeand 6 months after surgery and clinical examination recordings and post-operativecomplications were registered. Also at the final follow up limb alignment and patients’satisfaction was reassessed.ResultsThe early post operative complications were varus recurrence, knee pain and no sign of tibialnon-union or infection were observed. In final follow up the only observed complications werefew cases of mild genu recurvatum, knee pain and loss of correction. There was no relationshipbetween the underlying pathologies and loss of correction in this study and no significantdifference between age groups regarding loss of correction was observedConclusionThis method can be a feasible alternative for correction of genu varum because of a smallincision, being soft tissue friendly, a corticotomy instead of osteotomy, no internal fixationdevices, shorter duration and an acceptable rate of complications and recurrences and finallyhigher patient satisfaction.file:///E|/ISTA2010-Abstracts.htm[12/7/2011 3:15:47 PM]
