Abstract:
O bjective To introducetheosteotomyofacetabularmedialwallas a techniqueto facilitateanatomicalimplantationand securefitofacetabularcupsfordysplastichips. Methods Eighteen hipreplacementswereperformedwithuseofan osteotomyofacetabularmedialwalltostabilizethecups in 17 dysplasticpatients. The patientswere aged from35-70 years, withan averageof51.4 year. Among all thedysplastichips,4 were oftypeⅠ,7 oftypeⅡ,4 oftypeⅢ,and 3 oftypeⅣ accordingtotheCrowe criteria. A Ranawat trianglewas drawn on theX-ray film, and a supposedoptimalrotatingcenterwas located.Bothofthehorizontaland verticaldistancesbetweenfemoralhead and supposedrotatingcenterwas decreasedsignificantlyafteroperation.Results With medialwallosteotomy,alltheacetabularcomponents wereplacedinthetrueacetabulum.The diametersoftheimplantedcupswere44-56 mm withan averageof 50.78 mm . Medialbony wallwas preservedwithan averagethicknessof9.5 mm . The horizontaldistance was 21.09 mm (12-40 mm )preoperativelyand 3.73 mm (-3-10.1 mm )postoperatively,therewas statistical difference(t=7.95,P
