Periprosthetic fractures in patients with consequences of shoulder joint traumas

Complications of shoulder joint traumas stand as a significant concern in modern traumatology. Various forms of endoprosthetics offer the potential to restore lost function resulting from fractures or dislocations of the proximal humerus. In the context of a significant deficiency in the rotator cuff of the shoulder (RC) in elderly patients with notably aged injuries, reverse endoprosthetics (RE) emerges as a justifiable choice. The accrued experience from the widespread adoption of anatomical arthroplasty of the shoulder joint (PS) has significantly influenced the evolution of this approach. Complications and progressive failures with short-term outcomes prompted the quest for solutions to the challenges posed by complex fractures and dislocations through the method of reverse arthroplasty, originally devised for treating rotatory arthropathy of the shoulder. However, the extensive application of RE has not consistently yielded excellent and good results in all cases of post-fracture and dislocation consequences. Mechanical complications, particularly periprosthetic fractures, are prevalent in RE and occur three times more frequently than in anatomical total arthroplasty of the shoulder joint. The urgency of this problem, considering the diminished rehabilitation potential of patients against the backdrop of intraoperative or postoperative fractures of the humerus and scapula, leading to a persistent deficit in the function of the shoulder joint, underscores the necessity of this study.
