This case report evaluates current diagnostic and treatment approaches for intrapelvic acetabular migration, focusing on the rare but serious complication of acute limb ischemia following hip arthroplasty. A 67-year-old female with a history of total hip arthroplasty 10 years ago presented with acute limb ischemia after experiencing a traumatic event 72 hours prior, which had caused displacement of her hip prosthesis. Notably, she had a history of a traumatic event two years earlier for which she had been advised to undergo surgical correction, which she had refused.

Rare intrapelvic migration of a sliding hip screw after hip fracture fixation.

Sliding hip screws (SHSs) are commonly used for the operative treatment of extracapsular neck of femur fractures. We report 2 rare cases of intrapelvic migration of an SHS, resultant of non-unions, threatening regional major vessels. Only a handful of such cases have previously been reported in the literature.

Introduction: Total hip arthroplasty (THA) is commonly performed to alleviate hip pain and restore function. While generally safe, complications such as prosthesis migration can occur. Intrapelvic migration of hip prostheses, leading to bowel perforation and fistula formation, is a rare but severe complication requiring prompt diagnosis and management.

Bladder injuries, although rare, can occur as a complication of hip surgery, particularly when a hip prosthesis migrates into the bladder. We present the case of a 75-year-old woman with a bladder rupture secondary to prosthesis migration requiring repair via a transvesical approach. While total hip arthroplasty (THA) is common, intrapelvic complications such as bladder injury are less commonly reported.

Intrapelvic acetabular cup migration is a rare but serious complication that can occur following either primary or revision total hip arthroplasty. Medial acetabular wall weakening is considered the main predisposing factor for acetabular protrusion. A thorough preoperative plan is essential to advocate proper pelvic anatomy reconstruction, including osteosynthesis of the pelvis, if necessary, preservation of muscle and bone stock, and selection of the right prosthetic components without damaging adjacent anatomical structures.
