Axi+Line® Proximal Bunion Correction System Surgical Technique

Axi+Line® Proximal Bunion Correction System • 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...

Axi+Line® Proximal Bunion Correction System Surgical Technique Overview Pronation Correction IM angle and frontal plane rotation correction are built into the plate. The degree of first metatarsal pronation is linearly related to the amount medial deviation of the first metatarsal.13 Left Plate Right Plate Approximated Pronation Correction Approximated IM Angle Correction 1. Osteotomy Guide Standard medial incision should be made to visualize entire first metatarsal shaft. Prepare site using standard surgical techniques, such as resecting exotosis if present. Place left/right side specific...

Axi+Line Proximal Bunion Correction System - Surgical Technique Overview 2. Pin Insertion Insert Drill Tubes into the Osteotomy Guide. Place proximal Threaded Pin, then distal Threaded Pin, making sure to achieve bi-cortical purchase with both pins. 3. K-Wire Insertion Drive K-wire through dorsal hole, ensuring wire crosses both cortices. Remove K-wire and repeat for the middle and plantar diagonal holes. Remove non-threaded K-wires from diagonal holes. NOTE: Use a surgical marker on K-wires prior to drilling the three diagonal holes for better visualization when cutting osteotomy. 4....

Axi+Line Proximal Bunion Correction System - Surgical Technique Overview 5. Cut Keeping saw blade parallel to the proximal Threaded Pin, make a Proximal Modified Mau osteotomy by sawing along the line extending through the three holes created by the K-wires. Verify distal fragment mobility. 6. Trial Placement Based on desired degree of correction, select appropriate left or right Axi+Line Plate Trial (5, 7.5, 10 or 12.5 degrees of correction) and place trial over the Threaded Pins as shown. 7. Trial & Manual Plate Reduction Place Threaded Nuts on each Threaded Pin. Manually reduce with...

Axi+Line Proximal Bunion Correction System - Surgical Technique Overview Screw Placement It is recommended to use non-locking screws in holes 1,2,and 3. It is also recommended to use locking screws in holes A and B. NOTE: All holes will accept either locking or non-locking screws at surgeon discretion Thread Drill Tube into second distal hole. Using the provided AO Drill Bit, drill through both cortices and measure using either the Depth Gauge or using the Drill Bit’s laser scale as measured from the top of the Drill Tube. Remove Drill Tube. Verify plate is sitting flush to the distal bone....
