[Osteosynthesis of proximal humerus fractures]

Area of Science:

• Orthopedic Surgery
• Traumatology

Background:

• Fractures of the proximal humerus constitute only 5% of adult fractures.
• While 80% result in good outcomes due to stability and early mobilization, 20% pose challenges.
• These complex fractures risk poor reduction, inadequate fixation, humeral head necrosis, and shoulder ankylosis.

Purpose of the Study:

• To review current operative treatment strategies for displaced proximal humerus fractures.
• To highlight the benefits of minimally invasive osteosynthesis for complex cases.
• To emphasize the utility of the Neer classification system.

Main Methods:

• Review of current literature and treatment paradigms for proximal humerus fractures.
• Discussion of minimally invasive osteosynthesis techniques.
• Analysis of the Neer classification's role in treatment decisions.

Main Results:

• Minimally invasive osteosynthesis provides stability for early functional therapy in complex proximal humerus fractures.
• The Neer classification system is crucial for guiding treatment indications and surgical choices.
• Addressing biological aspects and fracture extent is key in operative management.

Conclusions:

• Operative treatment for displaced proximal humerus fractures has evolved towards less invasive methods.
• Minimally invasive osteosynthesis is a viable option for complex fractures, promoting early mobilization.
• The Neer classification remains a valuable tool for managing these injuries.
