Recruitment & Eligibility

Status: Recruiting

Sex: Not specified

Target Recruitment: 150

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

- *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.

Study & Design

Study Type: Interventional

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
<p>The primary endpoint is the residual fracture displacement (in mm), as measured<br /><br>on the postoperative CT-scan. </p><br>

Secondary Outcome Measures

Name	Time	Method
<p>The secondary endpoint includes patient reported outcome, which will be<br /><br>assessed with validated follow-up questionnaires at one-year follow-up.<br /><br>Additionally, surgery related factors e.g. operation time, intraoperative blood<br /><br>loss, and complications. For the patient-specific implants, the accuracy of the<br /><br>screw positions will be assessed by matching the preoperative virtual planning<br /><br>with the post-operative CT images.</p><br>
