locking cancellous screw
The locking cancellous screw represents a significant advancement in orthopedic fixation technology, combining robust mechanical stability with enhanced healing capabilities. This specialized medical device features a unique thread design specifically engineered for cancellous bone applications, where traditional screws might prove insufficient. The screw's distinctive locking mechanism creates a fixed-angle construct when paired with compatible plates, effectively preventing screw toggle and maintaining reduction stability throughout the healing process. Its design incorporates a larger thread diameter and deeper thread depth compared to cortical screws, allowing for superior purchase in less dense bone structures. The locking cancellous screw's thread pattern is specifically optimized for grip in metaphyseal regions, where bone quality may be compromised. Modern versions feature self-tapping designs that eliminate the need for pre-threading, streamlining the surgical process while maintaining precise placement control. These screws are typically manufactured from medical-grade titanium or stainless steel, ensuring both biocompatibility and durability. The locking feature provides enhanced stability in osteoporotic bone, making it particularly valuable for elderly patients or those with compromised bone density.
