with femoralrevision combined with (14) or without (7) attempted fracture fragment reduction; a diaphsealengaging stemwas utilized in all revisions. One patient was lost to follow-up leaving 31 patients for evaluationRESULTS: Nineteen (61%) patients sustained twenty-two major complications including nonunionof the greatertrochanter in 10 of the 12 Ag fractures, three Brooker grade 3 heterotopic ossification (10%),non-unions ofboth B-1 fractures (6%), two deep infections (6%), one stem subsidence that required repeatrevision (3%),one greater trochanteric fracture with instability (3%), one non-union of an extendedtrochantericosteotomy, one hematoma (3%) and one peroneal nerve palsy (3%). Seven patients (23%)required a secondoperative procedure for management of a complication and one patient required a thirdoperation.CONCLUSIONS: Operative treatment of acute post-operative periprosthetic fractures isassociated with a high rate of major complications (61%) and re-operation (23%). Operativetreatment of acute post-operative fractures of thegreater trochanter was associated with non-union in 10 of 12 cases (83%).Friday, October 8, 2010, 11:10-11:50Session A13: Alternate Bearing Materials in ArthroplastyModern Alternative Bearing Total Hip Arthroplasty in Patients Less Than21 Years OldAtul Kamath - University of Pennsylvania - Philadelphia, USA*Neil Sheth - OrthoCarolina - Charlotte, USAOladapo Babtunde - Columbia University - New York, USAHarish Hosalkar - University of California San Diego - San Diego, USAGwo-Chin Lee - University of Pennsylvania - Philadelphia, USACharles Nelson - University of Pennsylvania - Philadelphia, USA*Email: neilshethmd@gmail.comINTRODUCTION: Total hip arthroplasty (THA) is not commonly performed in youngpatients. However, markedly advanced hip disease can cause disabling end-stage arthritis, andTHA may be the only available option for pain relief and restoration of function. We report ourexperience with modern alternative bearing THA in patients younger than 21 years.METHODS: Twenty-one consecutive primary THAs were performed in 18 patients. Pre- andpost-operative Harris Hip Scores (HHS) and any postoperative complications were recorded.Radiographs were reviewed for evidence of premature component loosening.
