Saturday, October 9, 2010, 9:10-9:50Session A18: Complication ManagementDual Mobility Acetabular Implants-a Solution for Dislocating Total HipProsthesis: Our Early ResultsIntroduction*Sabyasachi Ghosh - Kettering General Hospital - Kettering, UKBhavik Shah - Kettering General Hospital - Kettering, UKHardik Bhansali - Kettering general Hospital - Kettering, UK*Email: docbapeted@hotmail.comRevision surgery is generally recommended for recurrent dislocation following Total hiparthroplasty (THA). However, dislocation following revision THA continues to remain aproblem with further dislocation rates upto 28% quoted in literature.We present early results of one of the largest series in U.K. using dual mobility cementedacetabular cup for recurrent hip dislocation.MethodsWe retrospectively evaluated 40 patients where revision of hip replacement was performedusing cemented dual mobility acetabular prosthesis for recurrent dislocations from March 2006till August 2009 at our district general hospital by a single surgeon (senior author). The seriescomprised of 13 men and 27 females with average age of 73.4 years (49-92). The mean followupperiod was 23 months. (36 months –6 months).All the hips that were revised had 3 or more dislocations, some them more than 10 times. Thecause of dislocation was multifactorial in majority of cases including acetabular componentmalpositioning mainly due to loosening and wear .A cemented dual mobility cup was used inall cases. In six cases the femoral stem was also revised.ResultsAt mean follow up of 26 months none of the revised THA had dislocated nor did they have anyfeatures of instability. No patients were lost for follow up. Clinically and radiologically therewere no features of loosening of the acetabular component.DiscussionThe dual mobility cup appears to be a reliable method in treatment for recurrent total hipdislocations. Although our early results are encouraging with no loosening of acetabularcomponents a further evaluation at longer follow- up is recommended.file:///E|/ISTA2010-Abstracts.htm[12/7/2011 3:15:47 PM]
