Reconstruction using the saddle prosthesis following excision of primary and metastatic XXXX .

@entity1 @entity530 @entity5
From 1988 to 1991, 17 @entity1 with @entity5 underwent limb-sparing surgery and reconstruction using the saddle prosthesis. There were 8 @entity1 with primary @entity5 (Group 1), and 9 @entity1 with metastatic or systemic @entity5 involving the periacetabular pelvis (Group 2). All resections included excision of the acetabulum. @entity1 ranged in age from 24 to 76 years (average, 59.8 years). Local control was achieved in all @entity1 . Wide margins were obtained in all @entity1 with primary @entity530 . Functional outcomes were rated as follows excellent (10), good (2), fair (1), and poor (4). Three @entity1 , all of whom had pulmonary metastasis before surgery, died within 8 months of surgery. Of the remaining 14 @entity1 , 5 @entity1 died between 6 and 28 months after the index procedure. At the end of the followup period, 9 @entity1 were still alive (6 in Group 1 and 3 in Group 2), with a followup period ranging from 15 to 62 months (average, 33.4 months). The overall results for surviving @entity1 were 7 excellent and 2 good results, with no fair or poor results.
