This section introduces screws used for general fractures.

General Fractures

CCS (cannulated screw)

The screw heads are Torx® shaped.

First Torx® shape screw to have been adopted by the medical industry.
It is superior in torque transferring ability and has a lower screw head profile.
The 3.0 mm and 3.5 mm versions designed to suit the skeleton of the Japanese are particularly highly rated.

  • Large choice of sizes
    3.0mmCCS（cancellous, cortical）
    3.5mmCCS（cancellous, cortical）
    4.0mmCCS
    4.5mmCCS
    5.5mmCCHS
    6.5mmCCHS
    Slipped capital femoral epiphysis (SCFE) screw （5.5/6.5mm)
  • Each size is available with flat or spike washers. (with some exceptions)
  • Self-drilling & self-tapping
  • Manufacture and sale approval number: 20700BZZ00125000  / Brand name: NRS titanium cannulated screw  / Material: Titanium alloy
  • Manufacture and sale approval number: 21000BZZ00335000  / Brand name: NRS titanium bone screw  / Material: Titanium alloy
  • Manufacture and sale approval number: 20900BZZ00861000  / Brand name: NRS titanium washer  / Material: Titanium alloy
  • Manufacture and sale approval number: 21200BZZ00607000  / Brand name: Titanium short thread screw  / Material: Titanium alloy

6.5mm CCHS（full thread）

  • Full-thread type（Total length: 100 mm to 150 mm）
  • Self-drilling & self-tapping
  • T30 Torx(6.5 mm CCHS and surgical instrument shared specification)
  • Reposition maintenance without compression is possible
    Please use along with conventional half-thread screws.

DTJ screw

The DTJ screw is a hollow screw that is optimal for insertion and fixation, allowing percutaneous screw insertion.

The screw heads are Torx® shaped.

  • The DTJ Mini Screw and DTJ Screw are unprecedented screws with a drilling mechanism and tapping mechanism at the distal screw tip, making drilling and tapping unnecessary.
  • These are hollow screws that are optimal for insertion and fixation, allowing minimally invasive percutaneous screw insertion.

*1：Since the DTJ Large Screw is not self-drilling, drilling is required.

Scaphoid fractures, etc.

DTJ screw (standard)

Hexagonal screw head

  • Uses 1.2-mm guide pin
  • Self-drilling & self-tapping

Available in most frequently used size range (20 mm to 26 mm), in 1-mm increments

  • Manufacture and sale approval number: 21200BZZ00606000  / Brand name: DTJ Screw  / Material: Titanium alloy

Scaphoid fractures, radial head fractures, etc.

DTJ mini screw

  • Uses 0.8-mm guide pin
  • Self-drilling & self-tapping
  • Length of 10 mm to 20 mm in 1-mm increments (except 11mm)
  • Manufacture and sale approval number: 21900BZX00736000  / Brand name: DTJ mini screw  / Material: Titanium alloy

Proximal tibia, distal fracture, etc.

DTJ large screw（*1）

  • Uses 1.6-mm guide pin
  • Self-tapping
  • Applicable for a wide range of cases centering on the lower extremities
  • Manufacture and sale approval number: 21500BZZ00664000  / Brand name: DTJ large screw  / Material: Titanium alloy
