Proximal Hemerus Phillos locking plate 3.5mm

Our Proximal Humerus PHILOS Locking Plate 3.5mm (Proximal Humeral Internal Locking System) is a state-of-the-art, high-stability orthopedic implant engineered specifically for the internal fixation of complex proximal humerus fractures. Highly effective for treating 2-part, 3-part, and 4-part fractures of the humeral head, this anatomically pre-contoured plate is the premier clinical choice for managing displaced fractures, dislocations, and challenging reconstructions in osteoporotic bone tissue.

Crafted from medical-grade, high-mirror electropolished Surgical Stainless Steel 316L or Premium Titanium Alloy, the plate features a widely expanded proximal head. This head cluster is meticulously engineered with an array of multi-directional, convergent, and divergent locking screw holes designed to securely capture fragments of the greater and lesser tubercles and form an ultra-stable subchondral raft beneath the humeral head. The structural plate shaft incorporates advanced combi-holes (locking/compression combination holes), providing orthopedic surgeons with maximum intraoperative flexibility to achieve rigid fixed-angle stability or apply standard dynamic axial compression.

Key Features & Benefits

• Multi-Directional Head Screw Array: The proximal head cluster accommodates multiple 3.5mm locking screws at targeted convergent and divergent angles, maximizing mechanical purchase in weak cancellous bone and preventing varus collapse.

• Advanced Shaft Combi-Holes: Dual-purpose combination holes in the plate shaft accept threaded locking screws for absolute structural rigidity or smooth-sloped cortical screws for standard axial compression.

• Dedicated Suture/Wire Eyelets: Features small specialized perimeter holes along the proximal head to allow the attachment of structural sutures or cerclage wires for reinforcing the rotator cuff tendons and securing tuberosity fragments.

• Fixed-Angle Construct Security: Threaded screw-to-plate locking eliminates screw back-out, plate migration, and loss of reduction—essential for successful healing in elderly patients with osteopenic bone quality.

• Anatomically Low-Profile Geometry: Smoothly rounded outer borders, a tapered distal tip, and a low-mass profile minimize post-operative subacromial impingement and reduce soft-tissue friction.
