Background

The suicidal jumper's fracture of the pelvis is a special form of sacrum fractures associated with high energy trauma. The typical H-type fracture pattern runs transforaminal on both sides with a connecting transverse component between S1 and S3. Due to the high-grade instability operative treatment is imperative. Aim of this study was to compare iliosacral double screwing (2×7,3mm canulated screw with 16mm thread) with spinopelvic internal fixation.

Methods

Both methods were tested on 6 synthetic and 6 anatomical pelvises. After osteotomy and alternating osteosynthesis stability was tested with a universal testing machine (Zwick) in a simulated two-leg stand. Data were generated by a 3-dimensional computer-assisted ultrasoundsystem (Zebris©) (3 translational datasets x,y,z and 3 ankles). Testing was performed after preload of 50N and two setting cycles of 100N followed by a full load cycle of 150N. ASCII-data were then transferred to SPSS for statistical analysis.
