Locking Pinion (Female locking pinion)

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

Function & Purpose :
——————

• The female locking pinion serves as the receptacle part that mates with the male locking pinion.
• It ensures a tight interlocking mechanism, preventing rotational play or loosening during elbow movement.
• Maintains mechanical stability and ensures smooth articulation throughout the range of motion.
• Provides secure coupling and maintains the alignment of the prosthetic hinge assembly.

Design Features :
——————

• Precision-machined internal grooves or teeth for accurate engagement with the male pinion
• Cup-like or socket configuration for firm interlocking
• Smooth internal finish to reduce friction and wear
• Allows easy assembly and removal during surgery

Advantages :
——————

• Provides secure mechanical interlock with the male pinion
• Ensures smooth hinge motion without instability
• Reduces wear, friction, and mechanical failure
• Enhances alignment accuracy of the elbow prosthesis
• Durable and reliable under repeated motion cycles

Applications :
——————

• Used in Total Elbow Arthroplasty (TEA) as part of the DKSORTHO Prathmesh Elbow System
• Connects with the Male Locking Pinion to form the central hinge mechanism
• Suitable for both primary and revision elbow replacements
