The PHILOS Proximal Humeral Locking Plates Titanium are orthopedic fixation implants designed for stabilization of appropriately selected proximal humerus fractures requiring operative fixation. The PHILOS-style configuration provides a dedicated proximal humeral locking platform with multiple screw trajectories intended to support fixation of the humeral head and proximal shaft.

Proximal humerus fractures can involve the humeral head, surgical neck, greater tuberosity, lesser tuberosity, or combinations of these structures. Fracture morphology can range from minimally displaced injuries to displaced, comminuted, unstable, and complex fracture patterns. In appropriately selected cases requiring surgery, a proximal humeral locking plate can provide a stable fixation construct while allowing controlled fixation of multiple fracture fragments.

The multi-angle locking design is intended to provide flexibility in the trajectory of compatible locking screws. Rather than relying solely on a single fixed screw direction, the system can allow screws to be positioned within the manufacturer’s specified angular parameters. This can assist the surgeon in targeting different regions of the proximal humerus and optimizing fixation according to fracture morphology and available bone stock.

The proximal portion of the plate is designed to accommodate multiple screws directed toward the humeral head. Appropriate screw positioning is particularly important because the humeral head has a complex three-dimensional anatomy and lies close to the glenohumeral joint. Screw length and trajectory should therefore be carefully planned using appropriate imaging and the manufacturer’s surgical technique.

The system includes 3-, 5-, 7-, 9-, and 11-hole configurations, providing multiple plate lengths and fixation spans. Shorter plates can be considered for appropriately localized fracture patterns, while longer plates may provide additional shaft fixation when clinically indicated. The appropriate configuration should be selected based on fracture location, fracture extension, bone quality, patient anatomy, and the surgeon’s fixation strategy.

The plates are manufactured from titanium, a material widely used in orthopedic implant applications because of its favorable strength-to-weight characteristics, corrosion resistance, and established biocompatibility. Titanium can provide a relatively lightweight implant while maintaining properties appropriate for orthopedic fixation. The exact titanium grade, mechanical properties, dimensions, and surface treatment should be confirmed through the manufacturer’s technical documentation.

The 52-piece selection provides multiple proximal humeral plate configurations for orthopedic trauma departments, hospitals, shoulder surgery units, surgical centers, and medical implant suppliers. The range of hole configurations allows selection of a suitable plate length according to the fracture pattern and desired fixation span.

PHILOS-style proximal humeral locking plates may be considered for selected displaced proximal humerus fractures, surgical neck fractures, tuberosity-associated fractures, comminuted fractures, and other appropriately selected proximal humeral fracture patterns requiring operative stabilization. They may be particularly useful where angular-stable fixation is clinically indicated. Final implant selection should be based on imaging, fracture classification, bone quality, soft-tissue condition, and surgeon judgment.

Accurate fracture reduction and restoration of appropriate proximal humeral anatomy are essential. The surgeon should assess the humeral head, tuberosities, shaft alignment, and fracture relationships before definitive fixation. Compatible reduction instruments, guidewires, drills, drill guides, depth gauges, and screwdrivers should be used according to the applicable surgical technique.

Screw placement requires careful attention because excessive screw length or inappropriate trajectory can result in joint penetration or damage to surrounding structures. Intraoperative fluoroscopy or other suitable imaging may be used to evaluate reduction, plate position, screw length, and the relationship of the screws to the humeral head and glenohumeral joint.

The plate should be positioned according to the manufacturer’s recommended anatomical landmarks and surgical technique. Soft-tissue handling is also important around the proximal humerus because the region contains important tendons, muscles, and neurovascular structures.

The implant should be handled carefully to prevent contamination, scratches, deformation, or damage to the threaded locking holes. Plate bending or modification should only be performed when specifically permitted by the manufacturer and using the approved technique. Unauthorized modification may affect the locking interface or structural performance.

Sterility, packaging, storage, and processing requirements depend on the manufacturer’s product labeling and supplied configuration. Reusable surgical instruments should be cleaned, inspected, packaged, and sterilized using validated healthcare-facility procedures according to applicable manufacturer instructions.

With 3–11 hole configurations, multi-angle locking technology, titanium construction, and a 52-piece selection, these PHILOS-style proximal humeral locking plates provide a versatile orthopedic fixation option for appropriately selected proximal humerus fracture procedures.

FAQs

1. What are PHILOS Proximal Humeral Locking Plates?

PHILOS-style locking plates are anatomical orthopedic implants designed for selected proximal humerus fractures. Their proximal portion provides multiple locking screw options for fixation of the humeral head and associated fracture fragments.

2. What hole configurations are available?

The product includes 3-, 5-, 7-, 9-, and 11-hole configurations, providing multiple plate lengths and fixation spans.

3. What does multi-angle locking mean?

Multi-angle locking allows compatible screws to be inserted at different permitted trajectories within the manufacturer’s specified angular range. This provides flexibility when targeting different regions of the proximal humerus.

4. What material are the plates made from?

The plates are manufactured from titanium, a material widely used in orthopedic implants because of its corrosion resistance, biocompatibility, and favorable strength-to-weight characteristics.

5. What fractures can proximal humeral locking plates be used for?

They may be considered for selected displaced proximal humerus fractures, surgical neck fractures, tuberosity-associated fractures, comminuted fractures, and other proximal humeral fracture patterns requiring operative fixation.

6. Why are multiple screw trajectories useful in proximal humerus fixation?

The proximal humerus has complex anatomy and variable fracture patterns. Multiple permitted screw trajectories can allow the surgeon to target different fracture fragments and regions of the humeral head according to the surgical plan.

7. Why is screw length important in proximal humerus surgery?

The humeral head is adjacent to the glenohumeral joint. Accurate screw measurement and trajectory control are therefore important to reduce the risk of unintended joint penetration.

8. Why are different plate lengths available?

Different hole counts provide different plate lengths and shaft fixation spans. The appropriate plate is selected according to fracture morphology, anatomical location, bone quality, and desired fixation strategy.

9. How many pieces are included?

The product is supplied as a 52-piece selection of proximal humeral multi-angle locking plates and associated compatible components according to the specified configuration.
