Locking Dynamic Hip Screw Plate

Specifications - Locking Dynamic Hip Screw Plate

  • Plates available holes are available in a wide range of sizes (3 to 16 holes) and barrel angles (130 degree, 135 degree, 140 degree, 145 degree), with 38 mm (standard) or 25 mm (short) barrels, for varied clinical situations..
  • Plate has combi holes and round holes. Combi holes allow fixation with locking screws in the threaded section and cortex screws in the dynamic compression unit section for compression.
  • The Locking Dynamic Hip Screw Plate lag screw, available from 50 mm to 150 mm lengths, easily glides within the plate barrel for controlled collapse and impaction of fragments. When the fracture requires additional intraoperative compression, the Dynamic Hip Screw Plate compression screw can be used; only one size compression screw is needed.
  • Two flats within the plate barrel correspond to the two-flat design of the Dynamic Hip Screw Plate lag screw, preventing rotation of the lag screw within the barrel. The two-flat design also eases insertion of the plate over the lag screw.
  • Locking Dynamic Hip Screw Plate allow implant placement to address the individual fracture pattern.
  • Limited-contact surface reduces bone-to-plate contact and helps to preserve the periosteal blood supply.
  • Dynamic compression plate holes in the Plate side plate allow angulation of 4.5 mm cortex screws, for lag screw fixation of medial fragments, and allow axial compression and multiple-screw fixation of the main fragment in subtrochanteric fractures with shaft extension.
  • Choice of different lengths of plate eliminates the need to cut plates.
  • Available in both Titanium and Stainless steel.
  • Locking plate increases construct stability, decreases risk of screw back-out and subsequent loss of reduction. It also reduces the need for precise anatomic plate contouring and minimizes the risk of stripped screw holes.
  • Polished surface and rounded edges minimize potential for tendon adhesion.
  • Low plate and screw profile minimizes potential for tendon and soft tissue irritation.
  • Smaller plates and screws address fracture fragments individually, with less overall implant bulk locking plate increases construct stability, decreases risk of screw back-out and subsequent loss of reduction.
  • A complete Instruments Set is available for Locking Dynamic Hip Screw Plate. General Instruments are available for this plate such as Plate Bending Press, Plate Holding Forceps, Plate Bending Pliers, Bone Holding Forceps, Bone Elevators, Bone Cutter, Bone Nibbler, Depth Gauge, Sleeve, Screw Driver, Trocar Sleeve etc.

Uses of Locking Dynamic Hip Screw Plate

The Locking Dynamic Hip Screw Plate is indicated for the following fractures of the proximal femur:

  • Pertrochanteric fractures of type A1 and A2
  • Intertrochanteric fractures of type A3
  • Basilar neck fractures B1, B2, B3
  • Subtrochanteric fractures

Benefits of Locking Dynamic Hip Screw Plate

  • Locking Dynamic Hip Screw Plate does not have to precisely contact the underlying bone in all areas. When screws are tightened, they “lock” to the threaded screw holes of the plate, stabilizing the segments without pulling the bone to the plate. Locking screws make it impossible for screw insertion to alter the reduction. Nonlocking plate/screw systems require a precise adaptation of the plate to the underlying bone. Without this close contact, tightening of the screws will pull the bone segments toward the plate, resulting in loss of reduction and possibly the occlusal relationship.
  • Locking plate/screw systems do not disrupt the underlying cortical bone perfusion as much as conventional plates, which compress the plate to the cortical bone.
  • Screws are unlikely to loosen from the plate. Similarly, if a bone graft is screwed to the plate, a locking head screw will not loosen during the phase of graft incorporation and healing. The possible advantage to this property of a locking plate/screw system is decreased risk of inflammatory complications due to hardware loosening.
  • Locking plate/screw systems have been shown to provide more stable fixation than conventional nonlocking plate/screw systems.
