Article Abstract
The aim of this study was to analyze the proteomic differences in bone marrow aspirate concentrate (BMAC) between extraction sites, specifically, the iliac crest and humeral head. Using support vector machine (SVM) models, SVM-(linear) and SVM-(rbf), we identified six key proteins (MCSF, CD14, CD40, CD163, Ephrin-A4, and Matrilin-3) as essential for distinguishing between these sites. The results indicate that site-to-site proteomic differences are likely influenced by the surrounding tissues of each extraction site. Higher levels of chondrogenic and osteogenic proteins in the humeral head BMAC in addition to immune-modulatory proteins in the iliac crest BMAC suggest site-specific proteomic profiles. This study provides insights that may assist clinicians in selecting site-appropriate BMAC for therapeutic applications and inform future research into BMAC proteomics.

Fibrin Sealant-Assisted Fixation of an Autologous Iliac Bone Graft in Orbital Floor Reconstruction.

Orbital floor fractures can lead to enophthalmos and diplopia, often requiring surgical intervention to restore orbital volume. Autologous iliac bone grafts are commonly used due to their biocompatibility and mechanical stability, but achieving adequate fixation remains a challenge. Traditional fixation methods, such as plates and screws, may introduce risks of foreign body reactions, graft displacement, and surgical morbidity.

Giant cell tumor (GCT) of the bone, although benign, demonstrates local aggressiveness, a potential for recurrence, and, in rare instances, malignant transformation. Functional preservation is crucial in cases involving the articular surface, often utilizing the Sandwich Technique. We propose an enhanced reconstruction method using the inner table of the iliac crest in a reverse fashion, offering a more anatomically contoured proximal tibial plateau and reducing donor site morbidity compared to tricortical iliac crest grafting.

Recurrent anterior instability with glenoid bone loss is a difficult problem with several surgical options. The Latarjet technique remains the gold standard for glenoid bone reconstruction in the setting of critical glenoid bone loss with excellent long-term outcomes. However, this technique has well known downsides including high rates of complications.
