Intrapelvic cementless component extraction with immediate triflange acetabular reconstruction using the retroperitoneal approach

Use of the retroperitoneal approach has been well documented and used for intrapelvic cemented components or cement masses. We report on a single stage revision hip arthroplasty that incorporates a retroperitoneal approach for safe removal of an extensively entrapped porous-coated acetabular component and modular femoral head followed by an immediate reconstruction using a triflange acetabular prosthesis via a posterior approach.
