- Abstract
Simple Summary: Reconstructing the proximal humerus after tumor resection remains a significant challenge, often resulting in reduced function and a diminished quality of life for patients due to the loss of soft tissues and bone. This research highlights the advantages of using an inverse tumor prosthesis for patients with proximal humerus bone tumors. It offers long-term results that have not been available in the existing literature, addressing concerns related to potential complications such as prosthetic loosening, infection, dislocation, and the loss of function. This study is valuable as it provides insight into an effective reconstruction method for a complex problem, fostering further research refinement in this field. Reconstructing the proximal humerus after tumor removal is challenging due to muscle and bone loss. The current methods often result in poor shoulder function. This study assessed the long-term functional and oncological outcomes of using an inverse proximal humerus prosthesis in 46 patients with bone tumors. The results showed a mean range of motion of 62° in anteversion, 28° in retroversion, and 55° in abduction. Notably, 23 patients achieved over 90° of shoulder abduction, with an average of 140°. The median Musculoskeletal Tumor Society Score was 25. Complications included infection in two radiotherapy patients and single dislocations in seven patients. One patient with recurrent dislocations needed revision surgery. In conclusion, the use of the inverse proximal humerus prosthesis in bone tumor treatment yields excellent shoulder function and high patient satisfaction. This approach is especially beneficial for those with metastatic disease.
