4.0 mm Cannulated Screws The 4.0 mm Cannulated Screw is developed for fracture fixation, fusion and osteotomy applications of large and small bones. The screws are cancellous threaded. In addition to the 16 mm threaded and fully threaded screws, the washers used for compression are also included in the set.


  • With their threads located distally, 16 mm threaded screws provide compression.
  • Fully threaded screws are used for fracture fixation.
  • The entire body of cannulated locking screws is threaded and is used for fixed angle fixation
  • It is used with 1.25 mm diameter k-wires.



4.0 mm Cannulated Screws are used for arthrodesis and osteotomies of small bones and small joints, including scaphoid and other carpal bones, metacarpals, tarsals, metatarsals, patella, ulnar styloid, capitellum, radial head and radial styloid.
