Introduction: The modified pedicle screw fixation (PSF) was designed to simulate an integrated framework structure to ameliorate the resistance to vertical and shearing forces of the disrupted sacroiliac complex, and the aim of this study was to compare the biomechanical characteristics of PSF and traditional lumbopelvic fixation (LPF) for the treatment of sacroiliac joint disruption.
Methods: The digital computer simulation model of an intact spine-pelvis-femur complex with main ligaments was built from clinical images. A left sacroiliac joint disruption model was mimicked by removing the concerned ligaments.
Article Synopsis
- - This study aimed to assess the mechanical stability of a modified pedicle screw fixator compared to unilateral lumbopelvic fixation for treating sacroiliac joint disruption using advanced simulation technology.
- - The researchers created digital models to simulate a typical spine-pelvis-femur structure and analyzed how each fixation method responded to a 400 N load, measuring displacement and stress distribution.
- - Results indicated that the modified pedicle screw fixator achieved significantly less displacement and stress on the bones and fixation components, along with greater stiffness, making it a more effective option than unilateral lumbopelvic fixation for this condition.
This study was to compare the relative strength of fixation and clinical outcomes of single lateral plate and double plating of comminuted supracondylar femoral fractures. Eight matched pairs of embalmed cadaveric femurs were selected. A gap osteotomy was created to stimulate an AO/OTA A3 comminuted distal femoral fracture.

Objective: To analyze the effectiveness ofvolar locking compression plate (LCP) and radial styloid process plate for the treatment of type C fractures of the distal radius.
Methods: Between May 2010 and May 2011, 24 cases of type C fractures of the distal radius were treated, including 8 males and 16 females with an average age of 52 years (range, 23-73 years). Injury was caused by falling in 20 cases and by traffic accident in 4 cases.
