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: This review assessed and compared the outcomes of open and arthroscopic iliac crest bone graft procedures for managing posterior shoulder instability (PSI). The results showed significant improvement in functional outcomes with arthroscopic procedures, but limited evidence was available for open procedures. There were differences in patient satisfaction and surgical complications between the two techniques. In conclusion, there is currently a lack of high-level evidence for bone block procedures using iliac crest bone graft in the management of PSI.

Summary: This study introduces a technique for measuring horizontal instability in acromioclavicular joint through sonography, which could assist in detecting this pathology. The research found a strong correlation between posterior clavicle translation and OLAC on sonography, and a very strong correlation between the difference in translation between healthy and injured shoulder with LE on sonography.

Summary: The goal of this study was to investigate clinical outcomes and risk factors for the progression of sacroiliac joint (SIJ) degeneration and bone formation after S2 alar-iliac screw (S2AIS) insertion. The results showed that about 10% of patients with preoperative SIJ degeneration had significant progression of degeneration. Bone formation was observed in about 6.9% of joints. However, neither the progression of SIJ degeneration nor the bone formation led to major complications or affected the postoperative clinical course.

Summary: Boxer elbow and handball goalkeeper elbow are types of impingement characterized by osteophytes formation. This study found that patients with these conditions may also develop exostosis at the posterolateral aspect of the elbow. MRI and CT scans are effective in detecting the formation of these bone abnormalities.

Summary: The study demonstrates that combining MRI with standardized loading allows for quantitative evaluation of knee joint functionality and grading of PCL deficiency. As PCL deficiency increases, joint dynamics also increase under loading. Stress MRI, when combined with advanced image post-processing, can be used to assess ligament functionality and joint laxity, potentially aiding in differentiating PCL injury patterns, therapeutic decision-making, and monitoring.

Summary: Radiofrequency ablation can alleviate pain in the posterior sacroiliac joint complex, but research is limited by variations in selection criteria, nerves targeted, and technology used for radiofrequency ablation.

Summary: This retrospective cohort study investigated the morphological changes in the sacroiliac (SI) joints in individuals with and without ossification of the posterior longitudinal ligament (OPLL). It was found that SI joint ankylosis occurred more frequently in patients with OPLL compared to those without. The presence of multilevel ossification in OPLL was associated with a higher rate of SI joint degeneration and ankylosis.

Summary: In this paper, the authors report their experience with the Sacrix system via the posterior oblique approach for sacroiliac joint fusion. The results show that this minimally invasive procedure is effective and safe, with excellent pain relief, improved function, and solid radiographic fusion.

Summary: In this study, the connection between inflammation, spinal ligament ossification, and sacroiliac joint changes in patients with OPLL was investigated. The results showed that the plateau-shaped ossification lesions were more common in the vertebral segments and were associated with higher hs-CRP levels and SI joint intra-articular fusion.

Summary: This study examined the outcomes of patients with prior isolated sacroiliac (SI) joint arthrodesis undergoing total hip arthroplasty (THA). It was found that these patients had a higher risk of dislocation following THA, but no significant differences in medical or surgical complications compared to patients without SI or lumbar arthrodesis.

Summary: Posterior hinge fixation (PHF) is a surgical method for treating unstable pelvic ring fractures (Tile C), which has shown good functional outcomes and pain control. Follow-up of more than 1 year revealed that 77% of patients achieved good or excellent clinical results, with surgical site infection being the main complication.

Summary: Fat is embedded within the ligaments of the sacroiliac joint, serving a stabilizing function. A software called VolSEQ was used to calculate the total volume and fat volume of the joint. CT scans of healthy individuals were analyzed, revealing differences in volume based on sex and age. The fat volume remains unchanged throughout life, while the joint volume is sex-dependent after 65 years old.

Summary: The purpose of this report is to demonstrate a new technique for creating a 4-rod lumbosacral construct when stacked S2AI screws are not possible due to concurrent treatment of sacroiliitis. The technique involves using a combined S2AI and subcrestal iliac approach to achieve the construct, while providing biomechanical support to the S2AI screws and treating the sacroiliitis.
