"literature article abstract entitled, ¿complications after hip resurfacing using the asr prosthesis in patients with osteoarthritis¿ by m.Klein, et al, published by z orthop unfall (2008), pp.179-84, doi: 10.1055/s-2008-1038397, was reviewed for mdr reportability.The purpose of this study was to evaluate peri- and postoperative complications and the clinical/radiological results after hip resurfacing with the asr prosthesis in patients with osteoarthritis.Materials: 115 asr cups and heads implanted between 1/2005 and 7/2006.At the time of follow-up an x-ray (a.P.And axial) of the operated hip was performed in addition to the to standard clinical examination.To measure the functional outcome the harris hip score was used.Results: there were 18 total complications.Three non-trauma-related femoral neck fractures were seen after a mean of 58 days (range: 41 to 70 days).One trauma-related femoral neck fracture was found after 7 months.Neural complications were found in two patients.In 8 patients a revision of the acetabular component was necessary, the reasons for revision surgery were unspecified.3 dislocations were treated without further revision.One revision was necessary because of a persisting pseudotumor without infection.No infections or thromboembolic complications were seen.The mean harris hip score developed from preoperative 59 points (range: 50 to 65 points) to postoperative 96 points (range: 85 to 100 points).Conclusions: excellent early postoperative results can be reached by hip resurfacing.This article is an abstract.No further information regarding patients or implanted products was available for review.This is for an asr cup and head.".
