Product Introduction

The Periarticular Proximal Humerus Locking Plate is designed for anatomical fixation of proximal humeral fractures. Its periarticular design combines an anatomically contoured profile with locking fixation to support stable fracture fixation while helping minimize soft tissue irritation.

The plate incorporates 20° conical threaded locking holes for angular-stable screw fixation. Its low-profile, highly polished design reduces the need for direct plate-to-bone compression, helping preserve the periosteal blood supply. Manufactured from TA3G pure titanium or TC4 titanium alloy, the plate is suitable for orthopedic fixation applications requiring biocompatibility and fatigue resistance.

Features

Angular-Stable Locking

• 20° conical threaded locking holes accommodate compatible locking screws to provide angular stability without requiring compression of the plate against the bone surface.
• The locking interface supports stable plate-screw fixation for complex proximal humeral fracture patterns.

Anatomical Contour

• Anatomically contoured geometry follows the shape of the proximal humerus to facilitate positioning and stable fixation.
• The periarticular configuration is designed for fixation close to the joint while maintaining a low-profile construct.

Low-Profile Plate Design

• Rounded edges and a highly polished surface help reduce soft tissue irritation and potential impingement.
• The low-contact design reduces the need for direct compression between the plate and bone.

Screw Compatibility

• Sharp self-tapping cutting edges facilitate screw insertion and can reduce the need for pre-drilling in applicable surgical situations.
• Compatible with cortical, locking, and cannulated screws with spherical or conical heads.

Surface Treatment

• Anodized surface treatment provides corrosion resistance and facilitates color-based identification.

Advantages

• Secure Angular Fixation: The 20° locking-hole geometry provides a stable screw-plate interface and supports fixed-angle fixation.
• Reduced Plate-to-Bone Compression: The locking design minimizes the need to compress the plate against the bone, helping preserve the periosteal blood supply.
• Soft Tissue-Friendly Design: Low-profile geometry, rounded edges, and a polished surface help minimize soft tissue irritation.
• Enhanced Handling: Anatomical contouring facilitates intraoperative positioning and reduces the need for extensive plate contouring.
• Stable Fixation in Osteoporotic Bone: The locking construct is designed to provide stable fixation in bone with reduced quality, including osteoporotic bone.

Indications

The Periarticular Proximal Humerus Locking Plate is indicated for internal fixation of:

• Proximal humerus fractures, including 2-part, 3-part, and 4-part fractures
• Metaphyseal fractures and osteotomies of the humerus
• Fractures involving osteoporotic bone or poor bone quality
• Complex periarticular and comminuted proximal humerus fractures requiring stable fixation
