A-DHS (Antirotator Dynamic Hip Screw) Plates

Antirotator Dynamic Hip Plate System (A DHS) increases the rotational stability of the femoral head thanks to the blade that can be sent over the lag screw that allows sliding compression. It consists of 4 parts: plate, lag screw, antirotator blade, and compression screw.

  • The flat-designed part of the lag screw extending distal matches the compatible notches in the barrel part of the plate and provides anti-rotation in the screw-plate system.
  • The femoral head stability is provided by the blade, which provides the stability by passing over the blade groove.
  • Anti-rotator blades are used as the same size as the lag screws and have 11 different size options.
  • ADHS contributes to reducing the risks of delayed union, preventing cut-out problems, and varus angulation of unstable trochanteric fractures.
  • Compression is provided at the fracture line with the help of a compression screw.



It is used in subtrochanteric, pertrochanteric, intertrochanteric, and femoral neck fractures.



Plate thickness: 6,5 mm

Plate width: 19 mm

The compression screw is 25 mm long and 4 mm in diameter. The screw head diameter is 9.5 mm and prevents the wedge from being “pull-out”.

Lag screw diameter: 8 mm

Lag screws offer 14 different length options from 50 mm to 115 mm, increasing at intervals of 5 mm.

Antirotator wedges offer length options from 60 mm to 110 mm.
