18 Years to 99 Years
Inclusion criteria
Inclusion criteria: - Patients >= 18 years with an acute (2 weeks from the injury) displaced acetabular fracture - Available diagnostic (preoperative) CT scan with slice thickness of
Exclusion criteria
Exclusion criteria: - Patients 2 weeks after the injury). - Pathological fractures. - Patient with previous hip surgery or surgery in the pre-peritoneal space (Stoppa approach) making an anterior intrapelvic approach hardly possible. - Patient unfit for acetabular surgery. - Patients with body-mass index (BMI) >35. - Acetabular fractures not suitable for an anterior intrapelvic approach
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To assess the accuracy of the screw placements. The accuracy of the screw placement (the difference between the intended position and the achieved position will be determined in terms of screw direction in degrees) which will be assessed, by matching the preoperative virtual planning with the post-operative CT images. | — |
Secondary
| Measure | Time frame |
|---|---|
| - To assess whether the use of 3D guided screw placement reduces the residual fracture displacement compared to a similar retrospective cohort. Residual fracture displacement is measured on the post-operative CT-scan in terms of: Gap (mm displacement in line with articular surface) and step-off (mm displacement perpendicular to the articular surface). - To assess whether 3D guided surgery leads to an increase in the efficiency of the operative treatment in terms of: operation time, time for plate contouring and fixation and surgeons satisfaction (about implant handling, positioning and fixation). | — |
