Total hip arthroplasty (THA) is an increasingly common procedure; more than 1 million hip arthroplasties are implanted worldwide per year . By dedicating this procedure to ever younger patients, revision of hip arthroplasties is to be expected to increase in the future. Periacetabular bone loss remains the greatest challenge in revision hip surgery [2-5]. The general principles in treatment of periacetabular bone loss still include restoration of bony continuity between the ilium and the ischium, and reconstruction of the anatomical hip center [6,7]. Intrapelvic cup protrusion provides many challenges, from implant removal, as nerves and vessels are at risk for injury, to the need to use massive acetabular allografts to reconstruct bone loss [8-10].
Girard et al.  have established an effective strategy to reduce complications to a minimum, while performing a revision in presence of a pelvic protrusion. We present the case of an acute intrapelvic migration of a broken acetabular component, and the strategy used to perform a successful revision
