Eligibility
Age
18 Years to 99 Years
Inclusion criteria
Inclusion criteria: - Patients >= 18 years with an acute (2 weeks from the injury) displaced acetabular fracture will be included after a signed informed consent. - Elementary acetabular fracture types (isolated posterior wall, isolated posterior column, anterior wall, anterior column and transverse fractures) - Associated type acetabular fracture types (posterior column and wall, transverse and posterior wall, T-type, anterior column and posterior hemitransverse, both column fractures).
Exclusion criteria
Exclusion criteria: - *Late* acetabular fractures more than 2 weeks after the injury - Pathological fractures - Patient with previous hip surgery or surgery in the pre-peritoneal space (Stoppa approach) making an anterior or posterior pelvic approach hardly possible. - Patient unfit for acetabular surgery (e.g. anterior and posterior approach in one tempi). - Patients with body-mass index (BMI) >35.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary endpoint is the residual fracture displacement (in mm), as measured on the postoperative CT-scan. | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary endpoint includes patient reported outcome, which will be assessed with validated follow-up questionnaires at one-year follow-up. Additionally, surgery related factors e.g. operation time, intraoperative blood loss, and complications. For the patient-specific implants, the accuracy of the screw positions will be assessed by matching the preoperative virtual planning with the post-operative CT images. | — |
