The Proximal Humerus Locking Plate is anatomically contoured for internal fixation of proximal humerus fractures. It features multiple 3.5 mm locking holes positioned at specific angles to support fixation of the humeral head and shaft.
The plate uses 20° conical locking screw holes to create a fixed-angle construct, providing angular stability and secure screw anchorage. This configuration is particularly suited to fixation where bone quality is reduced, including osteoporotic bone.
The plate is manufactured from TA3G pure titanium or TC4 titanium alloy, combining the material characteristics required for orthopedic fixation with biocompatibility, corrosion resistance, and mechanical performance.
The 20° conical locking holes are compatible with specially designed locking and cannulated screws, providing a secure threaded interface between the plate and screws.
The plate is anatomically contoured to the proximal humerus and incorporates rounded edges and a highly polished surface to help minimize soft-tissue irritation.
The anodized surface treatment provides corrosion protection and facilitates implant identification.
Sharp self-tapping screw tips facilitate screw insertion and help simplify the implantation procedure.
Ball-head cortical screws allow eccentric insertion when axial compression is required, providing additional flexibility during fracture fixation.
The plate is available in multiple lengths and hole configurations to accommodate different patient anatomies and fixation requirements.
The fixed-angle locking interface supports maintenance of fracture reduction and stable fixation in complex fracture patterns and reduced bone quality.
The angled locking screw configuration allows screws to be positioned to provide support within the humeral head.
The locking mechanism secures the screws to the plate without requiring direct compression of the plate against the bone, helping limit interference with the periosteal interface.
The low-profile plate design is intended to reduce implant prominence and the potential for subacromial impingement.
The deep-thread design of cancellous bone screws provides increased thread engagement in cancellous bone to support fixation.
The system accommodates both locking and non-locking cortical screws, allowing hybrid fixation techniques according to surgical requirements.
