Proximal Humerus Locking Plate Narrow with 4–14 Hole Fixation Range

Proximal Humerus Locking Plate Narrow, SKU PS-O-302, is an orthopedic implant plate manufactured in stainless steel and titanium options for fixation of proximal humerus fractures and shoulder reconstruction procedures. The available narrow head configurations include 4 holes, 5 holes, 6 holes, 7 holes, 8 holes, 9 holes, 10 holes, 12 holes, 13 holes, and 14 holes, allowing selection across compact, routine, and extended proximal humeral constructs. The visible implant design includes a contoured shaft, clustered proximal screw holes, elongated combination openings, countersunk seating zones, and a smooth machined surface for controlled intraoperative handling. It is used during two-part, three-part, and selected four-part proximal humerus fracture fixation, surgical neck fracture stabilization, greater tuberosity fixation, metaphyseal comminution support, proximal humeral osteotomy stabilization, nonunion reconstruction, and selected veterinary shoulder fracture repair. Orthopedic trauma surgeons, shoulder reconstruction specialists, sports trauma teams, hospitals, clinics, distributors, and veterinary orthopedic services can use this implant within CE, ISO 13485, and FDA-compliant procurement workflows.

Narrow Head Geometry and Proximal Screw Distribution

The narrow head profile is designed for proximal humeral fixation where the surgeon needs clustered screw purchase without excessive plate width across the lateral proximal humerus. The proximal hole group supports multiple screw trajectories into the humeral head, greater tuberosity region, surgical neck, and metaphyseal segment, helping distribute fixation across short or cancellous fragments. The contoured shaft follows the humeral cortex and provides a stable bridge from the proximal cluster into the diaphyseal support zone. Elongated combination openings along the shaft allow controlled plate positioning and compression or locking sequence planning before final fixation. Countersunk hole geometry helps screw heads seat within the implant surface after tightening, reducing prominence under the deltoid and surrounding soft tissue envelope. The narrow configuration is selected when the bony surface, patient anatomy, or surgical approach favors a reduced proximal plate footprint. This geometry supports angular stability, fragment capture, and shaft alignment during proximal humerus fracture reconstruction.

Shoulder Fracture Fixation and Reconstruction Workflow

In operative workflow, Proximal Humerus Locking Plate Narrow is introduced after deltopectoral or deltoid-splitting exposure, fracture assessment, reduction, tuberosity control, and provisional fixation have established the intended construct. During surgical neck fracture fixation, the shaft is aligned along the lateral humeral cortex while the proximal cluster is positioned to capture the humeral head segment. In three-part fracture patterns, proximal screws support the head and tuberosity fragments while shaft fixation maintains alignment across the metaphyseal transition. For greater tuberosity involvement, the implant works with reduction sutures, clamps, or temporary wires before final screw placement. In osteotomy or nonunion reconstruction, the plate maintains the planned relationship between proximal and shaft segments after bone preparation. Veterinary orthopedic teams can apply the same fixation principles when implant length, material, and screw system match the planned repair. Final assessment includes fluoroscopic screw length review, head penetration check, shoulder motion clearance, irrigation, and layered closure.

Selection Across 4, 5, 6, 7, 8, 9, 10, 12, 13, and 14 Hole Options

The 4 and 5 hole plates are selected for compact proximal humerus fractures where the shaft segment allows shorter fixation and the surgical exposure favors a smaller construct. The 6 and 7 hole options support routine proximal humeral fracture fixation with additional diaphyseal purchase for surgical neck and metaphyseal patterns. The 8 and 9 hole configurations provide broader load distribution when comminution extends distally or when tuberosity fixation requires a longer shaft support zone. The 10 hole plate is selected when the fracture line or osteotomy requires extended fixation beyond the proximal metaphysis. The 12, 13, and 14 hole options support long bridging constructs, segmental extension, revision fixation, nonunion reconstruction, and selected veterinary orthopedic repairs involving larger humeral anatomy. Hole-count selection is guided by fracture morphology, bone quality, proximal fragment size, tuberosity involvement, shaft extension, and the screw inventory available in the operating room implant system.

Implant Material, Sterile Handling, and Procurement Compliance

Stainless steel provides rigid fixation behavior and familiar handling for orthopedic trauma inventories, while titanium offers an alternate implant material for facilities managing mixed shoulder fixation systems. The smooth machined finish supports screw seating, visual inspection, and controlled handling during sterile tray preparation. Countersunk openings and elongated shaft holes require inspection before use so the selected screws seat correctly and the implant surface remains free of handling damage. The plate is managed through validated hospital implant handling, packaging, and sterilization workflows before implantation according to facility protocol. After implantation, removal, sterile-field contamination, or loss of sterile integrity, the implant is not returned to reusable instrument circulation. CE marking, ISO 13485 manufacturing controls, and FDA procurement context support purchasing files for hospitals, clinics, distributors, and orthopedic supply departments. The $17.60 price, one-piece MOQ, OEM availability, one-year warranty framework, and return or replacement support help procurement teams manage shoulder fixation inventory and distributor catalog requirements.

How does Proximal Humerus Locking Plate Narrow differ from Proximal Humerus Locking Plate Wide?
Proximal Humerus Locking Plate Narrow has a reduced proximal head footprint for shoulder fixation where a smaller lateral plate profile is preferred. Proximal Humerus Locking Plate Wide provides broader proximal coverage when the fracture pattern or bone surface requires wider screw distribution. The narrow version is selected when the surgeon wants clustered humeral head fixation without placing a wider implant under the deltoid region. The wide version is selected when fragment size, comminution, or tuberosity involvement requires broader proximal support. Proximal Humerus Locking Plate Narrow still provides shaft fixation through multiple hole-count options. The clinically relevant difference is proximal head width, soft-tissue profile, and screw distribution strategy.

Which hole count should be selected for proximal humerus fixation?
Proximal Humerus Locking Plate Narrow is available across 4, 5, 6, 7, 8, 9, 10, 12, 13, and 14 hole narrow head configurations. Short 4 and 5 hole plates are selected for compact fractures with limited shaft extension. The 6 and 7 hole options support routine surgical neck and metaphyseal fixation. The 8, 9, and 10 hole plates provide additional diaphyseal purchase when fracture extension or bone quality requires broader support. The 12, 13, and 14 hole configurations are selected for long bridging constructs, nonunion reconstruction, revision fixation, and selected veterinary orthopedic repairs. Selection depends on fracture morphology, humeral shaft extension, tuberosity involvement, implant length requirement, and operating room screw system planning.

How do CE, ISO 13485, and FDA details support procurement?
Proximal Humerus Locking Plate Narrow is supplied with CE, ISO 13485, and FDA procurement context for orthopedic implant purchasing. CE marking supports conformity documentation for healthcare markets requiring European medical device references. ISO 13485 indicates manufacturing under a medical device quality management system with controlled production and traceability. FDA procurement context supports hospitals, clinics, and distributors serving United States orthopedic supply channels. These details assist tender submissions, vendor onboarding, operating room inventory approval, and distributor catalog documentation. The $17.60 price, one-piece MOQ, OEM availability, and one-year warranty framework support replacement inventory and shoulder fixation tray planning.

How are the locking holes and elongated shaft openings used intraoperatively?
The elongated shaft openings can be used early in placement to help position the plate after fracture reduction and provisional fixation. The surgeon can refine plate height, rotation, and shaft alignment before final screw insertion. Proximal locking holes accept compatible screws that engage the implant and create angular stability across the humeral head and metaphyseal segment. Shaft screws then secure the construct along the lateral humeral cortex according to the selected hole count. Proximal Humerus Locking Plate Narrow is applied under direct visualization and fluoroscopic confirmation before final tightening. Final assessment includes screw length, trajectory, head penetration review, tuberosity reduction, shoulder motion clearance, and implant seating.

What should hospitals and distributors consider before ordering this implant?
Hospitals should select Proximal Humerus Locking Plate Narrow according to hole count, material preference, screw system, proximal humerus fracture workload, and shoulder reconstruction inventory needs. Stainless steel and titanium options allow procurement teams to align ordering with existing orthopedic implant protocols. Unused plates are managed through validated implant handling, packaging, and sterilization workflows before surgery. After implantation or sterile-field contamination, the plate is treated as a single-use implant and is not returned to reusable tray circulation. Distributors can stock available narrow head configurations to support trauma, shoulder reconstruction, veterinary, and teaching hospital demand. The one-piece MOQ, carton-box packing, OEM availability, warranty framework, and return or replacement service support practical inventory planning.
