Rim Plate to Buttress Plate for Posterior Wall Acetabular Fractures With and Without Inter-fragmentary Screws
A Randomized Prospective Study Comparing Rim Plate to Buttress Plate for Posterior Wall Acetabular Fractures With and Without Inter-fragmentary Screws
University of Cincinnati
60 participants
Aug 1, 2023
INTERVENTIONAL
Conditions
Summary
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.
Eligibility
Inclusion Criteria6
- Skeletally mature males and females, ≥ 18 years old and with age less than 65 years.
- Fracture of the acetabular posterior wall fracture due to acute traumatic hip dislocation, confirmed with anteroposterior pelvic or hip radiographs, and CT scan
- Operative fixation of fractures within 14 days of presenting to the emergency room.
- Patient was ambulatory prior to fracture, with or without walking aids
- Medically optimized for operative intervention
- Provision of informed consent by patient or legal guardian.
Exclusion Criteria8
- Patients not suitable for internal fixation (severe osteoarthritis, rheumatoid arthritis, or pathologic fracture).
- Pre-existing orthopedic fixation, implant, or prosthesis around the affected acetabulum.
- Patients with metabolic bone disease including diagnosis of osteoporosis.
- Patients with bony or soft tissue infections around the acetabulum.
- Patients unable to provide informed consent.
- Patients having other fractures of Pelvis or acetabulum other than an isolated posterior acetabular wall fracture.
- Patients with previous history of acetabular fracture (operative or nonoperative)
- Patients with previous history of hip pathology such as avascular necrosis, hip dysplasia, Legg-Calve Perthes Disease, or advanced degenerative arthritis.

Interventions
The posterior wall fracture will be operatively stabilized with a pelvic reconstruction plate and interfragmentary screws placed through the plate.
The posterior wall fracture will be operatively fixed with a buttress plate applied under compression without interfragmentary lag or position screws.
