Summary: Shoulder reconstructions with Anatomic (AN) or Reverse Shoulder (RS) Endoprosthesis (EPR) after Malawer type 1 resection show similar complication rates, but RS EPR significantly improves post-operative range of motion and functional outcomes.

Summary: There are various treatment options available for proximal humerus fractures, and the choice should be based on the fracture characteristics and patient's condition. Although the indications for hemiarthroplasty have narrowed, there is still a place for this technique in practice.

Summary: This study aimed to explore the risk factors for surgical site infection (SSI) after internal fixation in patients with closed proximal humerus fractures. The results showed that high BMI, smoking, an increase in mean time from injury to definitive surgery, and prolonged surgical time were independent risk factors for the development of SSI in patients with closed proximal humerus fractures.

Summary: This study compared and evaluated the biomechanical performance of the extra-articular distal humerus plate (EADHP) and a modified proximal humerus locking plate (PHILOS) using finite element analysis. The results suggest that the PHILOS could be a viable alternative to the EADHP for the fixation of distal humerus shaft fractures.

Summary: RSA is a suitable treatment option for head-split fractures, with good clinical and radiographic outcomes; high-energy trauma has a significant impact on functional results, while patients with multifragmentation to the humeral head perform the worst.

Summary: Proximal humerus fractures, the third most common fracture type in adults, have diverse approaches to classification and treatment, with optimal treatments still under debate. This review summarizes current and historical treatment modalities for proximal humerus fractures, providing updates on advancements and trends in epidemiology, classification, and both operative and nonoperative treatments.

Summary: The aim of this study was to investigate the factors affecting the local and systemic prognoses of conventional, central chondrosarcomas (CSs) originating from the proximal humerus. The results showed that grade 1 CSs of the proximal humerus behaved as benign tumors with no local recurrence or deaths due to disease. Grade 2 CSs were locally aggressive but had low mortality rates and high disease-specific survival rates. The surgical management of grade 2 CSs should focus on preserving function while achieving margin-free resection.

Summary: Intraosseous schwannomas in the humerus are extremely rare, with less than five cases reported in the literature. This case presents a rare occurrence of intraosseous schwannoma with pathologic fracture in the proximal humerus. The patient underwent successful treatment with excisional biopsy, curettage, bone allograft, and fracture fixation, with no recurrence after 6 months of follow-up.

Summary: Although proximal humerus fractures account for a small percentage of all fractures, the bilateral differences of the proximal humerus are significant, with males showing more differences than females. Using contralateral data as a template for repairing an affected proximal humerus may still be possible.

Summary: This study aimed to investigate the impact of rehabilitation compliance on clinical outcomes for non-surgically managed PHFs and identify ways to improve compliance. The results showed a strong correlation between rehabilitation compliance and short-term clinical outcomes, with pain being the main reason for non-compliance.

Summary: A variation of the phase field method embedded into the finite cell method is proposed to simulate impacted humeral fractures in fresh frozen human humeri. The method is validated by comparing the force-strain response, failure loads, and fracture path with experimental observations. The results show good agreement and accurately predict the compressive failure pattern and force-strain relationship in proximal humerus fractures.

Summary: Reconstructing the proximal humerus after tumor removal is challenging due to muscle and bone loss. This study evaluated the long-term functional and oncological outcomes of using an inverse proximal humerus prosthesis in 46 patients with bone tumors. Results showed excellent shoulder function and high patient satisfaction, with a mean range of motion of 62 degrees in anteversion, 28 degrees in retroversion, and 55 degrees in abduction. This approach is particularly beneficial for those with metastatic disease.

Summary: The study evaluated the indications, feasibility, clinical effectiveness and complications of microwave inactivation in situ combined with curettage and bone grafting for proximal humerus tumors. The results showed that this treatment is feasible for proximal humerus tumors, especially malignant and metastatic tumors, without the need for shoulder replacement, with minimal trauma, good upper limb function, and low rates of local recurrence and distant metastasis.

Summary: This study aimed to develop a standardized and reliable computerized method for measuring three-dimensional spatial displacements of proximal humerus fractures (PHFs). Through analyzing CT scans of 77 PHFs, it was found that 96% of fractures could be measured using three-dimensional calculations, with 47% classified as displaced fractures according to Neer's criteria. Compared to two-dimensional methods, three-dimensional measurements provided more accurate assessment of displacement in PHFs.

Summary: Operative times for lower extremity orthopedic trauma increased as resident seniority increased. Senior resident participation was associated with increased wound dehiscence, whereas junior resident participation was associated with an increased risk of deep surgical site infections. Academic quarter within the academic year did not correlate with any of the surgical complications.

Summary: The clinical practice guideline focuses on the treatment of severe lower limb trauma and provides evidence-based recommendations for key decisions on limb salvage versus early amputation. There are 11 recommendations in the guideline to evaluate important decision factors. The work group also emphasized the need for further research on the treatment of high-energy lower extremity trauma and the shared decision-making process.

Summary: Tourniquets are critically important for controlling traumatic extremity hemorrhage. This study investigated the effects of prolonged tourniquet application and delayed limb amputation on survival, systemic inflammation, and remote organ injury. The results showed that prolonged tourniquet application and delayed limb amputation increased the risk of complications, including systemic inflammation and dysfunction of remote organs. Improved strategies are needed to mitigate these systemic effects, especially in military settings. Additionally, further research is necessary to extend the time window for evaluating limb viability after tourniquet deflation and develop new point of care tests to assess the risks of tourniquet deflation for limb preservation and patient care optimization.

Summary: Patients with combat-related lower extremity amputations experience a rapid decline in bone mineral density in both amputated and intact limbs, stabilizing after approximately 3 years, with an average loss of 100 HU after 1,000 days. Other factors affecting bone mineral density include ambulatory status, age, surgical complications, level of amputation, and vitamin-D treatment.

Summary: The aim of this study was to develop a data-driven approach for identifying limb salvage cases and studying their clinical outcomes. With the use of medical code data, a population of 2018 US Service members who underwent limb salvage was identified, representing 59.5% of the combat-related lower extremity trauma population. Comparison with expert opinion showed moderate agreement, and the approach demonstrated potential for future retrospective analyses of short- and long-term outcomes.

Summary: This study aimed to develop and characterize a closed intra-articular fracture (IAF) mediated post-traumatic osteoarthritis (PTOA) model in rats to serve as a testbed for putative disease modifying interventions. The results showed that a high-energy (5 J) blunt-force impact effectively induced intra-articular fractures in rats and resulted in typical osteoarthritic changes at 56 days, suggesting that this model can provide a reliable testbed for screening disease modifying interventions for high-energy joint injuries.
