Rim Plate to Buttress Plate for Posterior Wall Acetabular Fractures With and Without Inter-fragmentary Screws

Description

The hypothesis of this study is that the Rim Plate method utilizing interfragmentary screws placed through the plate will result in superior fixation, a lower rate of loss of reduction of the fracture fragment, better anatomic healing of the articular (joint) surface, a decreased rate of early post-traumatic arthritic changes of the joint (cartilage) surface, and improved functional outcomes.

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.

Eligibility Criteria

  • 1. Skeletally mature males and females, ≥ 18 years old and with age less than 65 years.
  • 2. Fracture of the acetabular posterior wall fracture due to acute traumatic hip dislocation, confirmed with anteroposterior pelvic or hip radiographs, and CT scan
  • 3. Operative fixation of fractures within 14 days of presenting to the emergency room.
  • 4. Patient was ambulatory prior to fracture, with or without walking aids
  • 5. Medically optimized for operative intervention
  • 6. Provision of informed consent by patient or legal guardian.
  • 1. Patients not suitable for internal fixation (severe osteoarthritis, rheumatoid arthritis, or pathologic fracture).
  • 2. Pre-existing orthopedic fixation, implant, or prosthesis around the affected acetabulum.
  • 3. Patients with metabolic bone disease including diagnosis of osteoporosis.
  • 4. Patients with bony or soft tissue infections around the acetabulum.
  • 5. Patients unable to provide informed consent.
  • 6. Patients having other fractures of Pelvis or acetabulum other than an isolated posterior acetabular wall fracture.
  • 7. Patients with previous history of acetabular fracture (operative or nonoperative)
  • 8. Patients with previous history of hip pathology such as avascular necrosis, hip dysplasia, Legg-Calve Perthes Disease, or advanced degenerative arthritis.
