A Randomized Prospective Study Comparing Rim Plate to Buttress Plate for Posterior Wall Acetabular Fractures With and Without Inter-fragmentary Screws
University of Cincinnati
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.
Description
Study type: Interventional Estimated enrollment: 60 Allocation: block randomization. The block randomization method is designed to randomize subjects into groups that result in equal sample sizes. This method is used to ensure a balance in sample size across groups over time. Interventional model: parallel assignment Description: two different methods of screw and plate fixation of posterior wall acetabulum fractures. Time perspective: Prospective Population: Skeletally mature patients who have presented with an acute traumatic fracture of the posterior wall of acetabulum due to dislocatio…

Inclusion 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.

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