What this Trial Is About

Researchers are evaluating two different surgical methods for fixing fractures of the posterior wall of the acetabulum, a part of the hip bone. This study focuses on patients who have experienced an acute traumatic fracture due to dislocation of the femoral head. The goal is to compare the Rim Plate method, which uses interfragmentary screws through the plate, against the Buttress Plate method without these screws, to see which provides better fracture stability, joint surface healing, and functional outcomes while reducing early arthritic changes. The study involves two groups of 30 patients each. One group will receive the Rim Plate treatment with interfragmentary screws placed through a pelvic reconstruction plate. The other group will be treated with a Buttress Plate applied under compression without interfragmentary lag or position screws. All surgeries are performed by surgeons experienced in both techniques, and patients undergo operative fixation within 14 days of injury. Participants will be assessed over 12 months for fracture displacement, healing of the posterior wall fragment, and loss of joint space. Functional outcomes will be measured using multiple hip and health scores. Patients will have regular evaluations including imaging and clinical exams to monitor recovery, healing, and joint health. The study aims to provide detailed insights into how these two fixation methods perform over time in adults with this specific hip fracture.
