Eight Plates

Specifications - Eight Plates

Guided growth using Eight Plates are commonly used for correction of angular limb deformities in growing children. The principle is of tethering at the physeal periphery while enabling growth in the rest of the physis. The method is also applied for epiphysiodesis to correct limb-length discrepancy.
The Guided Growth Eight Plates System acts like a flexible hinge and it can temporarily inhibit bone growth in the area where plates and screws are applied.
By tethering only one side of the physis (hemiepiphysiodesis), bone growth is not inhibited in the remaining areas of the growth plate, providing the potential to redirect the growth of long bones to gradually correct angular deformities of lower limbs.
By tethering two opposite sides of the same physis the longitudinal bone growth is temporarily halted, providing the potential to correct limb length discrepancies.

  • Plates available holes are .
  • 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.
  • Eight Plates 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.
  • 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 Eight Plates. 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 Eight Plates

Eight Plates are used for control and correction of angular deformities like genu valgum or varus by a performing epiphysiodesis.

Eight Plates serves as a tension band and restores the physiological axis. The tension band plate, with screws on either side of the physis, creates a non-rigid fulcrum outside of the physis, relatively lengthening the moment arm. Due to screw fixation, the risk of hardware extrusion is minimal.

Plates could be used and applied at the area of the knee, hip or ankle joints or to the area of the elbow and wrist.

Benefits of Eight Plates

  • Eight Plates 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.
