* Multiplanar sacral fractures are characterized by the combination of horizontal and bilateral vertical fracture lines, leading to complex fracture types.* With a resultant disconnect between the cephalad axial spine and the caudad segment attached to the pelvis and lower extremities, these fracture characteristics, along with associated soft-tissue complications, make these injuries difficult to treat.* Outcomes are maximized with stable fixation and often are based on initial neurological compromise, which can be a reliable predictor of a return to a functional level.* Several methods of reconstructing the posterior pelvic-sacral complex exist, each with its own advantages and disadvantages.* Surgeons should select a fixation strategy on the basis of a careful analysis of the specific fracture pattern and resultant vectors causative of pelvic, sacral, and spinal deformity.

A two-stage revision of an infected TEA with a periprosthetic fracture can be managed successfully with our novel hinged antibiotic-loaded cement spacer.

Introduction: In the revision setting, intrapelvic acetabular components provide a unique set of challenges for the treating surgeon. Retrieval is complicated by complex anatomical relationships within the pelvis and historically, surgeons have used multiple approaches to safely retrieve the cup. Case presentation: We present the case of a 53-year-old female with intrapelvic migration of the acetabular components of her total hip arthroplasty. Patient was treated through a novel, single incision approach with utilisation of an anterior inferior iliac spine (AIIS) osteotomy. Results: An AIIS osteotomy allows for improved visualisation within the pelvis and safe retrieval through a single exposure without compromising the ability to perform definitive, revision reconstruction. At 1-year follow-up, the patient has had no complications related to infection or failure of the implants. Ambulation is performed with the aid of a cane in the community with mild, occasional pain.
