Article Synopsis
- Acetabular fractures are complex injuries that pose significant challenges in surgery due to their anatomy, prompting interest in minimally invasive endoscopic techniques as an alternative approach.
- The study involved 34 participants with varying surgical experience, assessing four coupling mechanisms for a new suprapectineal plate, focusing on failed attempts, fixation time, and the influence of experience on outcomes.
- Results show that plates with grooved and pressure-sliding mechanisms performed better with fewer failures and shorter times, and participants rated these designs as more supportive and feasible for minimally invasive surgeries.
Pelvic ring injuries or acetabular fractures present a challenge to trauma surgeons. Recently, endoscopic dissection techniques for visualization of the anterior pelvic ring and acetabulum have been presented. Robotic-assisted surgical systems offer advantages in terms of improved visualization and easier instrument handling.

The process window for highly efficient laser-based powder bed fusion (LPBF), ensuring the production of parts with low porosity, was determined by analyzing cross-sections of samples that were generated with laser powers varying between 10.8 W and 1754 W, laser beam diameters varying between 35 μm and 200 μm, and velocities of the moving laser beam ranging between 0.7 m/s and 1.
