Abstract
The surgical techniques and outcomes of acetabular reconstruction for periprosthetic
pelvic discontinuity cases are reported. The mean time to surgery for 9 patients with
acute pelvic discontinuity was 16.3 days, with 8 patients (88%) having posterior column
plating and a porous metal acetabular cup. No cases required revision surgery, with
a mean follow-up of 34 months (range, 24-67 months). Of the 62 chronic pelvic discontinuity
cases, 20 had an ilioischial cage, with a revision rate of 29%. There were 42 cup-cage
reconstructions with an 8-year survivorship of 86.3%, with a mean follow-up of 35
months (range, 24-93 months). Stable reconstruction of chronic pelvic discontinuity
was achievable by distraction using a cup-cage acetabular reconstruction; however,
satisfactory stability of acute pelvic discontinuity was achieved with compression
of the posterior column using screw augmentation of the acetabular shell supplemented
by posterior column plating.
