Humerus shaft fractures, approaches and management

Area of Science:

• Orthopedic surgery
• Traumatology
• Skeletal repair

Background:

• Humeral shaft fractures are common injuries with evolving treatment strategies.
• Conservative treatment with functional bracing faces challenges due to rising nonunion rates.
• Surgical interventions are increasingly considered for optimal outcomes.

Purpose of the Study:

• To update current trends in managing humeral shaft fractures.
• To describe surgical indications for plate osteosynthesis and intramedullary nailing.
• To review advancements in treating associated radial nerve palsy.

Main Methods:

• Review of current evidence and surgical techniques for humeral shaft fractures.
• Description of open reduction internal fixation (ORIF) for simple fractures.
• Explanation of minimally invasive plate osteosynthesis (MIPO) and intramedullary nailing (IMN) approaches.
• Discussion of ultrasound-guided diagnosis and management of radial nerve palsy.

Main Results:

• ORIF remains suitable for simple AO/OTA type A fractures.
• MIPO offers a less invasive approach with relative stability and callus formation.
• IMN is gaining acceptance due to improved implant designs and techniques.
• Ultrasound provides reliable diagnosis of radial nerve conditions, comparable to intraoperative findings.

Conclusions:

• Treatment indications for humeral shaft fractures require re-evaluation due to conservative treatment nonunion rates.
• MIPO and IMN represent significant advancements in surgical management.
• Further randomized controlled trials are needed to refine treatment guidelines for humeral shaft fractures.
