Summary: The biomechanical effects of topping-off instrumentation on the sacroiliac joint (SIJ) after lumbosacral fusion were investigated. It was found that the use of topping-off devices increased motion, stress, and ligament strain at the SIJ, suggesting a higher risk of degeneration and pain compared to fusion alone.

Summary: While anterior sacroiliac joint fixation shows better performance in reducing stresses and loads, posterior fixation remains the preferable treatment due to its less invasive nature and potential for improvement with different screw and cage configurations.

Summary: This study aimed to elucidate the biomechanical mechanism of sacroiliac joint pain caused by sacroiliac joint subluxation. A finite element model was established to quantify simulate the subluxation, and the results showed that different shifts of the sacroiliac joint led to varying stress and strain on ligaments and articular surfaces, potentially resulting in sacroiliac joint pain.

Summary: This study analyzed how the number of implants affected SIJ stabilization with patient-specific characteristics, showing that one or two implants can decrease the joint range of motion but three implants did not further improve joint stability, and that low bone density can affect joint stabilization.

Summary: This study aimed to investigate the biomechanical effects of horizontal meniscal tears and different resection strategies on a rabbit knee joint using finite element analysis. The results showed that the horizontal meniscal tears had little biomechanical impact on the rabbit knee joint, and some of the partial meniscectomy strategies also had minimal effect on joint stress. It is recommended to preserve the posterior root and the remaining peripheral edge of the meniscus during surgery for a horizontal meniscal tear.

Summary: The percutaneous SI screw is commonly used for posterior ring disruption in pelvic fractures, but its placement is difficult and can damage adjacent neurovascular structures. The SAI screw is a safe and reliable technique for sacral pelvic fixation. Finite element analysis showed that SAI screws provided biomechanical stability for SI joint dislocation. Various fixation methods achieved sufficient stability, with the TS1 + TS2 group having the smallest displacement and lowest peak screw stress. These findings suggest that SAI screws are a valuable option for treating SI joint dislocation.

Summary: Artificial joint revision surgery often requires patient-specific prostheses for bone defect repair. This work presents a clinical case on the design and mechanical analysis of 3D-printed porous tantalum prostheses for knee revision, providing useful guidance for designing patient-specific prostheses.

Summary: This article is a systematic review of diagnostic tests for identifying the source of low back pain. The findings suggest that there are informative tests for the disc, sacroiliac joint, and facet joint, which can guide targeted treatment approaches.

Summary: This paper proposes an effective thermal design scheme for space manipulator joints based on their thermal characteristics, including the harsh external thermal environment, complex flight attitude, and large internal power dissipation. The adaptability of different sizes of radiating surfaces under extreme operating conditions is compared and analyzed. The results show that a radiating surface with dimensions of 100 mm x 120 mm meets the thermal requirements in extreme high and low-temperature running modes. The study provides a theoretical basis for improving the reliability and thermal optimization of manipulator joints.

Summary: This study aimed to assess biomechanical parameters in fused and contralateral sacroiliac joints (SIJs) and implants during spinal motions for males and females. Results showed that females had lower stresses and greater reductions in motion at the contralateral SIJ compared to males. Implants in females had higher stresses than in males, but the risk of implant failure in females was still minimal. Surgical approaches were effective in both sexes, with the lateral approach potentially providing a better biomechanical response, especially in females. Design characteristics of the implants did not have a significant impact on biomechanical performance.

Summary: Minimally invasive SI joint fusion using the iFuse Implant System showed greater improvements in pain and physical function compared to conservative management at 6 months, with similar findings at 1- and 2-year follow-ups. Adverse events were higher in the fusion group, with a revision surgery incidence up to 3.8% at 2 years. Limited evidence is available for comparing different minimally invasive devices.

Summary: This study compares the effects of compression, traction, and oblique-pulling manipulation on sacroiliac joint (SIJ) motion, and finds that oblique-pulling manipulation can cause nutation and separation of the SIJ, which may be neutralized by regular standing and weight-bearing load.
