Clinical and Functional Outcomes of Proximal Humerus Internal Locking System Plate Fixation in Proximal Humerus...

Area of Science:

• Orthopedic Surgery
• Traumatology
• Biomechanics

Background:

• Proximal humerus fractures (PHFs) are common, especially in the elderly.
• Complex and displaced PHFs often necessitate surgical intervention.
• Proximal Humerus Internal Locking System (PHILOS) plating is an effective option, particularly for osteoporotic bone.

Purpose of the Study:

• To evaluate the efficacy of PHILOS plating for treating proximal humerus fractures.
• To assess functional outcomes and patient recovery following PHILOS plate fixation.

Main Methods:

• A 2-year retrospective and prospective study included 30 patients (aged 18-65) with PHFs.
• Fractures were classified using Neer's classification and treated with PHILOS plating.
• Functional outcomes were assessed using the Constant-Murley score after a minimum 4-month follow-up.

Main Results:

• The mean age was 39.56 years; 2-part (33.3%), 3-part (56.6%), and 4-part (10%) fractures were observed.
• Excellent outcomes were achieved in 46.7% of patients, with a mean Constant-Murley score of 78.
• 2-part fractures showed the highest mean score (81.2), while 4-part fractures had the lowest (59.3).

Conclusions:

• PHILOS plate fixation offers stable internal fixation for PHFs.
• The procedure facilitates early mobilization and leads to good-to-excellent functional outcomes.
• Less complex fracture patterns and early rehabilitation positively impact recovery.
