Stoppa approach for intrapelvic damage control and reconstruction of complex acetabular defects with intra-pelvic socket migration: A case report

The para-rectus approach for extraction of intra-pelvic migrated acetabular implants

Primary and revision total hip arthroplasty can be complicated by intrapelvic migration of the acetabular components. This complication constitutes an evolutionary turning point in the history of this prosthesis since it could lead to compression or invasion of noble intra-pelvic structures. The second problem lies in the extraction of these implants in this anatomically dangerous region. We report the case of a patient who was operated on for a septic loosening of her total hip arthroplasty with protrusion of the acetabular components (Kerboull cross-plate and the cup) intrapelvicly via the para-rectus approach which allowed safe removal of these implants. This is an intra-pelvis approach lateral to the rectus abdominis muscle, initially described in acetabular fractures, with few studies reporting its use in this type of complex situations.

Artificial intelligence planning and 3D printing augmented modules in the treatment of a complicated hip joint revision: a case report

Total hip revision with osseous defects can be very difficult. Artificial intelligence offers preoperative planning, real-time measurement, and intraoperative judgment, which can guide prothesis placement more accurately. Three-dimensional printed metel augment modules which are made according to the individualized osseous anatomy, can fit the osseous defects well and provide mechanical support. In this case, we used AI to plan the size and position of the acetabular cup and 3D-printed augmented modules in a complicated hip revision with an acetabular bone defects, which achieved stable fixation and relieved hip pain postoperatively.

Modified Stoppa Approach for Acetabulum Fracture: A Review

Fracture acetabulum is a grave injury and a challenge for orthopedic surgeons. Anterior and posterior approaches have been described for fixation of acetabulum fractures. The modified Stoppa approach is considered an alternate to anterior approach, which provides access to pelvis from inside the cavity. The purpose of this article is to review the available literature on use of the modified Stoppa approach in acetabulum fractures. The available data suggest that modified Stoppa approach is useful in anterior acetabulum fractures and some posterior acetabulum fractures, especially where buttressing of medial wall is required.
