Locking Pinion (Male locking pinion)

Material : Stainless Steel LVM (316LVM)
Size : STD.

Function & Purpose :
——————

• The male locking pinion acts as a central locking mechanism between the humeral and ulnar components.
• It provides rotational stability and prevents micro-motion at the articulation interface.
• Ensures firm mechanical coupling and alignment throughout the range of motion.
• Designed to allow smooth, secure hinge motion while maintaining implant integrity.

Design Features :
——————

• Precision-machined male pinion teeth for accurate interlocking with the female counterpart
• Cylindrical shaft design for smooth rotation
• Polished surface finish to minimize wear and friction
• Ensures easy assembly and disassembly during surgery

Advantages :
——————

• Provides secure locking between implant components
• Maintains mechanical stability and alignment
• Reduces wear and loosening over time
• Facilitates smooth, natural elbow motion
• Durable and reliable under repetitive joint loading

Applications :
——————

• Used in Total Elbow Arthroplasty (TEA) with the DKSORTHO Prathmesh Elbow System
• Connects the humeral stem and ulna component through a mechanical hinge mechanism
• Suitable for both primary and revision elbow replacements
