An article ¿mean 5 year clinical and radiographic outcomes of 40 consecutive cementless total hip arthroplasties in 34 patients under the age of 30¿ by jeremy m gililland et al reports a retrospective review of radiographic and clinical results following total hip arthroplasty in a series of 40 young patients under the age of 30 (16 males, 24 females; mean age- 22 years) with advanced coxarthrosis primarily secondary to noninflammatory processes using modern cementless implants and bearing couples between 1996 to 2008.Following hip implants were used: taperloc and s-rom for femoral components; m2a or magnum, asr, pinnacle for acetabular components.Perioperative complications include relatively high estimated blood loss and rate of transfusions, dislocation (n=4), infection (n=1) and pulmonary embolism (n=1).This article also indicates two intra-operative fractures, but it does not specify the product (depuy or another) associated with these adverse events, and the information whether the fracture was patient bone or implant device.7 cases underwent to revision surgery in which depuy products were used in 4 cases (3 with mom-asr articulation (depuy srom and depuy asr); and 1 case with mop articulation (depuy srom and biomet rb)).2 of mom-asr articulation) out of 3 were revised due to metallosis while other one was due to aseptic loosening (acetabular and femoral component).One case of mop was revised due to periprosthetic femur fracture.No clarification was found on which events were specifically present on specific patients except implant used and adverse event.Asr was found to be associated with above reported adverse events.Case # 2 involves patient who was diagnosed with osteoarthritis underwent mom-asr revision after 26.7 months.Patient received revision for both components: depuy srom as femoral component and depuy asr as acetabular component (per table 3, page 4).Noted are the following patient adverse events: infection, pulmonary embolism, dislocation, high estimated blood loss and rate of transfusions, aseptic loosening.Noted are the following product adverse events: implant loosening (stem).
