Proximal Humerus Locking Plate Multiple Sizes with 5–14 Hole Cobra Head Range

Proximal Humerus Locking Plate Multiple Sizes, SKU PS-O-112, is an orthopedic implant plate manufactured in stainless steel and titanium options for proximal humerus fracture fixation and shoulder reconstruction. The available cobra head configurations are 5 holes, 7 holes, 8 holes, 9 holes, 10 holes, 11 holes, 12 holes, 13 holes, and 14 holes, giving surgeons graded construct length for compact, routine, and extended proximal humeral fixation. The visible implant design includes a broad cobra head, clustered proximal screw holes, elongated combination shaft openings, countersunk seating zones, and a smooth machined surface for controlled handling during implantation. It is used during surgical neck fracture stabilization, greater tuberosity fixation, metaphyseal comminution support, proximal humeral osteotomy stabilization, nonunion reconstruction, selected three-part and four-part fracture patterns, and 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.

Cobra Head Geometry and Fixed-Angle Screw Support

The cobra head profile is designed to place multiple proximal fixation points across the humeral head and metaphyseal region while the shaft extends distally along the lateral humeral cortex. Clustered head holes support divergent screw trajectories for capturing the head segment, greater tuberosity fragment, surgical neck, and cancellous metaphyseal bone. The elongated shaft openings allow provisional positioning, compression planning, and controlled adjustment before final locking screw placement. Countersunk seating zones help screw heads sit within the implant surface after tightening, reducing prominence beneath the deltoid and adjacent soft-tissue envelope. In a locking construct, the screw head engages the plate hole to create fixed-angle support, which is clinically important when comminution or reduced bone quality limits compression-based fixation. The curved shaft helps follow the proximal humeral contour and maintains alignment between the head cluster and diaphyseal support zone. This geometry supports fragment capture, angular stability, and staged fixation during proximal shoulder fracture reconstruction while preserving a predictable plate orientation throughout screw sequencing.

Shoulder Fracture Fixation and Reconstruction Workflow

In operative workflow, Proximal Humerus Locking Plate Multiple Sizes is introduced after deltopectoral or deltoid-splitting exposure, fracture assessment, reduction, tuberosity control, and provisional fixation. During surgical neck fracture stabilization, the shaft is aligned with the lateral humeral cortex while the cobra head is positioned to capture the head fragment. In three-part fracture patterns, proximal screws support the humeral head and tuberosity fragments while shaft fixation maintains alignment across the metaphyseal transition. In selected four-part fractures, the implant assists fixation after reduction of the head, tuberosities, and shaft relationship has been established. For osteotomy or nonunion reconstruction, the plate maintains corrected alignment after bone preparation, decortication, graft placement, or segment repositioning. Veterinary orthopedic teams apply the same fixation principles when patient size, bone geometry, material preference, and screw system match the planned repair. Final assessment includes fluoroscopic screw length review, head penetration check, tuberosity reduction, shoulder motion clearance, irrigation, and layered closure before postoperative implant documentation is completed for operating room records.

Selection Across 5, 7, 8, 9, 10, 11, 12, 13, and 14 Hole Plates

The 5 hole cobra head plate is selected for compact proximal humerus fractures where short shaft fixation is adequate and the operative exposure favors a smaller construct. The 7 and 8 hole configurations support routine surgical neck and metaphyseal fracture fixation with added diaphyseal purchase. The 9 and 10 hole options provide broader shaft support when fracture extension, comminution, or osteotomy planning requires additional working length. The 11 and 12 hole plates are selected for longer fracture lines, nonunion reconstruction, revision fixation, and cases where load distribution must extend farther down the humeral shaft. The 13 and 14 hole configurations support long bridging constructs, segmental instability, and selected veterinary orthopedic repairs involving larger humeral anatomy. Cobra head selection is guided by proximal fragment size, tuberosity involvement, shaft extension, bone quality, and planned screw trajectory. Hospitals can stock the full range to cover compact, routine, and extended shoulder fixation workflows in trauma and reconstruction trays without changing implant family classification or set layout.

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 plating systems. The smooth machined implant surface supports screw seating, visual inspection, and controlled handling during sterile tray preparation. Countersunk openings and elongated shaft holes require inspection before use so compatible screws seat correctly and the plate surface remains free of handling damage. This implant 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 plate 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 $22.00 price, one-piece MOQ, OEM availability, one-year warranty framework, and return or replacement support help procurement teams manage proximal humerus implant inventory, material selection, and distributor catalog requirements across stainless steel and titanium configurations.

How does Proximal Humerus Locking Plate Multiple Sizes differ from Proximal Humerus Locking Plate Narrow?
Proximal Humerus Locking Plate Multiple Sizes uses a cobra head configuration for clustered proximal fixation across the humeral head and metaphyseal region. Proximal Humerus Locking Plate Narrow has a reduced proximal footprint for cases where a slimmer lateral plate profile is preferred. The cobra head version is selected when the surgeon wants broader proximal screw distribution and graded construct length from 5 to 14 holes. The narrow version is selected when the surgical approach, bony surface, or soft-tissue envelope favors a smaller head profile. Proximal Humerus Locking Plate Multiple Sizes provides additional hole-count options for extended shaft support in longer constructs. The clinically relevant difference is head shape, proximal screw distribution, and implant footprint during shoulder fracture fixation.

Which hole count should be selected for proximal humerus fixation?
The 5 hole plate is selected for compact fracture patterns with limited shaft extension. The 7 and 8 hole options support routine surgical neck and metaphyseal fixation where additional diaphyseal purchase is required. The 9 and 10 hole plates are selected when fracture extension or comminution needs broader shaft support. The 11 and 12 hole configurations support nonunion reconstruction, revision fixation, and longer metaphyseal-to-diaphyseal constructs. The 13 and 14 hole plates are selected for extended bridging, segmental instability, and selected veterinary orthopedic repairs involving larger humeral anatomy. Selection depends on fracture morphology, proximal fragment size, tuberosity involvement, shaft extension, bone quality, and planned screw trajectory.

How do CE, ISO 13485, and FDA details support procurement?
Proximal Humerus Locking Plate Multiple Sizes is supplied within 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 $22.00 price, one-piece MOQ, OEM availability, and one-year warranty framework support replacement inventory and shoulder fixation tray planning.

How are the cobra head holes and elongated shaft openings used intraoperatively?
The cobra head holes are used to distribute proximal screw fixation into the humeral head, tuberosity region, surgical neck, and metaphyseal segment. The elongated shaft openings can be used early in placement to help control plate height, rotation, and shaft alignment after reduction. The surgeon confirms implant position under direct visualization and fluoroscopic review before completing the final screw sequence. Locking screw engagement creates angular stability across the proximal cluster and supports fixation when cancellous bone purchase is limited. Proximal Humerus Locking Plate Multiple Sizes is applied after reduction, provisional fixation, and trajectory planning have been completed. Final assessment includes screw length, 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 Multiple Sizes according to hole count, material preference, screw system, shoulder fracture workload, and 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 the 5–14 hole cobra head range 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.
