Product Description

Combines the advantages of intramedullary nailing with high cephalic stability. Its double axis cephalic screws allow either parallel sliding screw or convergent locking screw placement to provide the surgeon with one nail to treat even the most difficult pertrochanteric fractures.

Indication
  • Proximal locking is accomplished via two possible configurations: parallel by means of two sliding screws that permit controlled compaction of the fracture site, or convergent with two screws converging in the femoral head and locked firmly to the nail.
  • Locked convergent screws are used to treat unstable fractures 31.A3 according to the AO classification, where the cephalic screws do not pass across the fracture line. Dynamic distal locking is recommended in 31.A3 fractures.
  • Parallel sliding screws are used to treat fractures 31.A1 and 31.A2 according to the AO classification in fractures where the cephalic screws pass across the fracture line to permit controlled compaction. Static distal locking is optional in 31.A1 fractures and recommended in 31.A2 fractures.

Physician Benefits

Proximal and distal diameter permits percutaneous insertion without reaming in the majority of elderly patients. The unique feature that distinguishes it from other double axis systems is the alternative configuration of the cephalic screws, with either two parallel sliding screws or two convergent screws locked to the nail. The surgeon therefore has a versatile implant to treat all types of trochanteric fractures. The instruments are thus contained and the appropriate stability provided for early rehabilitation.

  • 10 mm distal and 15 mm proximal diameter minimizes trochanteric entry damage and permits percutaneous insertion without reaming
  • Inventory contained in only one instrument tray
  • Lateral wall preservation via two small cephalic screws
  • Rotational stability
  • Increased biomechanical strength
  • MRI compatible titanium nail and locking screws 10 mm Static hole Dynamic hole 10 mm
