Functional and Radiological Outcome of Proximal Humerus Fractures Treated with Proximal Humerus Internal Locking...

Area of Science:

• Orthopedic Surgery
• Traumatology
• Biomedical Engineering

Background:

• Proximal humerus fractures are common, particularly in the elderly, often leading to pain, stiffness, and functional loss with non-operative management.
• Displaced fractures require effective treatment to restore shoulder function and prevent long-term complications.

Purpose of the Study:

• To evaluate the functional and radiological outcomes of displaced proximal humerus fractures treated with the proximal humerus internal locking osteosynthesis (PHILOS) system.
• To assess the efficacy of the PHILOS plate in achieving stable fixation and promoting early mobilization.

Main Methods:

• A study involving 20 patients (18-75 years) with displaced proximal humerus fractures (Neer's 2, 3, or 4-part, or associated with dislocation) treated with the PHILOS plate between April 2022 and April 2024.
• Patients were followed up at 4 weeks, 12 weeks, and 6 months, with functional outcomes assessed using the Constant-Murley Shoulder score.

Main Results:

• Excellent functional outcomes were observed in 7 patients, good in 10, moderate in 2, and poor in 1, with a mean Constant-Murley score of 81.26 at final follow-up.
• Neer's 2- and 3-part fractures demonstrated better functional and radiological outcomes compared to 4-part fractures.
• The PHILOS plate allows for more screw fixation points, enhancing stability for humeral head fractures.

Conclusions:

• Surgical treatment of proximal humerus fractures, particularly with the PHILOS plate, provides significant stability, facilitates early mobilization, and leads to a good range of motion.
• The PHILOS system is a viable option for managing displaced proximal humerus fractures, offering improved outcomes over conventional plates.
• Early mobilization and stable fixation are crucial for optimal recovery following proximal humerus fractures.
