Axi+Line™ Proximal Bunion Correction System

Axi+Line™ Proximal Bunion Correction System

The Axi+Line Proximal Bunion Correction System addresses treatment of deformities of larger angles and addresses correction in the frontal plane.

  • Corrects both IM angle and frontal plane deformity
    • 87.3% of patients with hallux valgus have abnormal frontal plane rotation (pronation) of the 1st metatarsal1
    • Other proximal/midshaft osteotomies, such as the Scarf do not address the frontal plane deformity, which has been shown to result in a recurrence rate of 78 percent2
  • The long oblique Proximal Modified Mau osteotomy
    • Provides intrinsic stability that may allow (at surgeon’s discretion) for early weight bearing3,4,5
    • Maximizes fusion surface area and provides the ability to correct moderate to large angular deformities4,6
    • Avoids violating a healthy metatarsal-cuneiform joint compared to a Lapidus procedure
    • Minimizes the probability of shortening compared to performing sawcut Lapidus procedure without use of the interposition autograft6,7
  • Osteotomy guide
    • Provides a templated path for a precise osteotomy
  • Instrumentation provides full control of all bone fragments during the procedure and allows for a seamless transition from templating to plating
    • Four angles of correction built into the plate, providing a self-reducing, 5-hole construct with bicortical locking or non-locking screw options
    • Sterile kit – provides added efficiency and convenience for surgical team8
