Endoprosthetic reconstructions for bone XXXX .

@entity1 @entity0 @entity2045 @entity5 @entity79 @entity3
The purpose of the current study was to help define the role that endoprosthetic reconstructions have in the treatment of metastatic @entity79 . Of the 522 endoprostheses implanted at the University of California at Los Angeles (UCLA) between December 1980 and January 2002, 37 (6.9%) were used in 37 @entity1 with @entity3 . @entity2045 locations outnumbered lower extremity locations 2:1. The 20 males and 17 females ranged in age from 10 to 82 years, with a median age of 54 years. Metastatic @entity0 predominated and accounted for 60% of the lesions. The lesion was a primary @entity3 in 27 @entity1 (73%) and a revision of failed previous surgery in 10 @entity1 (27%). Only five @entity1 experienced local complications none of whom required reoperation or amputation. Thirty-three of the 37 @entity1 died of disease progression at a median of 12 months (range, 4-49 months). Function after endoprosthetic reconstruction for @entity3 is similar to that of function for endoprosthetic reconstructions used for primary @entity5 , but clearly is dependent on the @entity1 's general condition. Although infrequently used to treat bone @entity3 , endoprosthetic reconstruction can be a useful alternative reconstruction in selected situations.
