Provides corrections of intermetatarsal (IM) Angle and Frontal Plane Deformity, offering a seamless transition from templating to plating to produce precise, reproducible outcomes.
Provides corrections of intermetatarsal (IM) Angle and Frontal Plane Deformity
In one study of 166 feet, 87.3% of patients with hallux valgus had abnormal frontal plane rotation, also known as pronation, of the 1st metatarsal1
The Proximal Modified Mau Osteotomy:
- Provides superior intrinsic stability compared to most other midshaft, proximal osteotomies2-4
- Maximizes fusion surface area and provides the ability to correct moderate to large angular deformities2,5
- Avoids violating a healthy metatarsal-cuneiform joint compared to a Lapidus procedure
- Minimizes shortening of the metatarsal by eliminating the need to remove healthy bone while eliminating the need for interpositional grafts.5,6
Procedure Hallux Valgus (or Bunion)
Precise, Reproducible Osteotomy
Long Oblique Proximal Modified Mau Osteotomy
The system includes an Osteotomy Guide that provides a visible path for surgeons to cut a long oblique Proximal Modified Mau osteotomy.
The Axi+Line Proximal Bunion Correction System instrumentation provides full control of all bone fragments during the procedure and allows for a seamless transition from templating to plating.
The Axi+Line Proximal Bunion Correction System can be used to correct IM angle deformities of up to 18 degrees.
4 Left plates and 4 right plates
- Correction of 5°, 7.5°, 10°, 12.5°
- Instrumentation is designed to provide full control of all bone fragments during the procedure and allows for a seamless transition from templating to plating.
All components in kits are pre-sterilized
- Instrumentation has never been used, damaged, or worn prior to surgery
- Time and cost savings as sterilization before surgery is no longer necessary
- Complete sets at delivery minimizes time at the back table
