Robotic Total Hip Arthroplasty for Traumatic Acetabular Fracture Using an Image-free Second-Generation System.

Complex traumatic acetabular fractures with concomitant hip dislocations are an orthopaedic emergency often requiring open reduction and internal fixation; however, total hip arthroplasty (THA) for acute acetabular fractures may be indicated in certain scenarios. This study reports the case of a 65-year-old male who had a motor vehicle collision that resulted in acetabular fracture dislocation with concomitant femoral head fracture. The patient underwent acute image-free robotic THA. At 6-month follow-up, the patient had good pain management and was doing well after surgery. With the reported technique using a reamer basket, an image-free robotic system can be used in acute THA in patients to achieve appropriate cup positioning.
