Is this trial a fit for you?

Likely a good fit

Ideal candidates are skeletally mature individuals aged 18 to 65 with acute posterior wall acetabular fractures due to hip dislocation.

Probably not a fit

Patients with severe osteoarthritis, metabolic bone diseases, or those unsuitable for internal fixation will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates two surgical techniques for fixing posterior wall acetabular fractures: the Rim Plate method with interfragmentary screws and the Buttress Plate method without screws. The study aims to determine which method provides better fixation, reduces the risk of fracture displacement, promotes better healing of the joint surface, and minimizes early post-traumatic arthritis. A total of 60 skeletally mature patients with acute traumatic fractures will be randomly assigned to one of the two treatment groups. The outcomes will be assessed to evaluate the effectiveness of each surgical approach.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and functional recovery for patients with acetabular fractures.

How similar studies have gone: While similar surgical techniques have been explored, this specific comparison of the Rim Plate and Buttress Plate methods is novel.

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. Medically optimized for operative intervention
6. Provision of informed consent by patient or legal guardian.

Exclusion Criteria:

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)
