Dual Mobility in "High Risk" Patients

Description

The aim of this study is to compare clinical outcomes of patients considered to be high risk for prosthetic dislocation undergoing primary total hip arthroplasty (THA) with the use of a dual mobility bearing versus a conventional, single bearing design.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * Primary THA for a diagnosis of osteoarthritis or inflammatory arthritis in the setting of a history of prior lumbar or lumbosacral fusion performed at least 6 months prior to their THA. In addition, patients considered high-risk for potential prosthetic dislocation will be included based on the presence of one or more of the following: neuromuscular disorder (e.g. cerebral palsy, Parkinson's disease, history of a stroke), dementia or cognitive impairment, substance or alcohol abuse (\>10 drinks per week), acute displaced femoral neck fracture, age \> 75 years, inflammatory arthritis, and increased preoperative range of motion (calculated as described by Krenzel et al.: combined flexion, adduction, internal rotation \> 115 degrees).
  • * Less than 18 years of age
  • * Revision THA
  • * spinopelvic fusion that is more recent than 6 months prior to THA
  • * isolated cervical or thoracic fusion
  • * intent to undergo a revision spinopelvic fusion within one year of their index THA
  • * a history of prior infection in the affected hip
  • * a history of prior open surgery on the affected hip (i.e. prior proximal femur fracture or osteotomy)
  • * or a preoperative diagnosis of post-traumatic arthritis, avascular necrosis, or fracture
