“…Metal on metal bearings, which allow a head size closer to that of the native femoral head. These implants have displayed low rates of dislocation but their utilization has waned due to concerns of adverse reactions to metal debris (ARMD) [85,86]. Dual mobility constructs allow for large femoral head diameter in addition to an increased arc of motion, and will be discussed more thoroughly later in this chapter.…”

Total hip arthroplasty (THA) is becoming one of the most frequently sought-after surgeries in orthopedics. As the techniques and implants continue to evolve, the stability of the prosthesis is always at the forefront of the surgeon’s mind. Multiple factors contribute to implant stability and there are many intraoperative decisions that can be made by the surgeon to increase stability. Techniques including approaches, adjusting length, adjusting offset, as well as implant choices can dictate stability in THA. There are multiple options that exist including different liners and constraint. One non modifiable variable which surgeons often struggle with is the spinopelvic relationship which can also affect stability post operatively. These factors include lumbar arthritis, variable pelvic tilt, and others that can make a routine approach to a total hip unsuccessful and increase the risk of post-operative complications. Ultimately there are many things to consider when approaching THA in patients, especially in the setting of abnormal pathology.
