ARIX Fibula Plate is indicated for the following conditions ‧AO-OTA 44 B (trans-syndesmotic) , C (supra-syndesmotic) lateral malleolar fractures ‧Non-unions after lateral malleolar fracture fixation ‧ tabilization of osteotomies of the metaphyseal and diaphyseal region of the distal fibula, especially in S osteoporotic bo

Lateral Distal Fibula Plate Hole for 1.6 mm positioning pin Shaft holes: 3 ~ 8 holes Minimized distal thickness less than 1.3 mm Oblong holes for syndesmosis screw insertion General Features • Anatomically pre-contoured • Low profile with 2.0 mm thickness • No screw head overhang avoids irritation • Four choices in screw types and sizes - Locking and cortical screws - 2.8 mm or 3.5 mm in screw diameter • Variable locking up to ± 15° • Plates length with 3 to 8 shaft screw holes No screw head protrusion Tapered screw hole enables surgeons to control appropriate trajectory for syndesmosis...

Refined shape of the plate head is based on the bone anatomy • Posteroinferior end of distal fibula corresponds to the recess for the posterior talo-fibular ligament(PTFL). • Screw holes over posterior talo-fibular ligament(PTFL) is redundant due to its thickness which only allows placement of very short screws. • No screw penetration in the recess for PTF ligament minimizes soft tissue irritation & potential articular cartilage damage. Lateral View Ø 2.8 mm & Ø 3.5 mm locking- or cortical screws applicable No screw penetration in recess for posterior talo-fibular ligament Inferior View...

Lateral Distal Fibula Plate - continued STARIX Screw with self-retaining function • Internal recess T10 according to international standard • Minimizes the risk of cam-out and recess breakage • Allows higher torque transmission • Optimal self-retaining function achieved through precision machining Variable Locking Interface with Locking Screw • Poly-axial screw insertion • Angle range: ±15° • Plate-screw locking interface Screw Options Self-retaining function of STARIX screw Allows easy screw pick up from the box and prevents screw fall out

Instrument – Variable Angle Drill Sleeve ❶ he variable angle drill sleeve enables the surgeons to T insert locking screws with preferred angle in range of +/ -15°. ❷ he drill sleeve handle facilitates engaging the drill sleeve T into the screw holes. Assemble the sleeve handle to the drill sleeve. Once the drill guide is engaged to the screw hole by turning it clockwise, disconnect the drill sleeve handle by simply pulling it out.

Surgical Technique 1. Patient Positioning and Exposure Position the patient in supine and make a straight lateral or posterolateral surgical incision to expose the fracture of the fibula based upon the fracture pattern and surgical planning. When posterior malleolar fragment is planned to be stabilized via posterolateral approach, a floppy lateral position with posterolateral incision can be considered. Most AO 44 B simple spiral lateral malleolar fractures can be reduced directly with a Weber or lion jaw clamp. Once anatomical reduction is verified with c arm images a lag screw can be...

Surgical Technique 4. Distal Screw Placement distal plate holes can accept either Ø 2.8 mm or Ø 3.5 mm All locking screws. To insert screws into the distal cluster of holes, drill 2.7 mm drill bit (112-35-703) for 3.5 mm screws through 2.7 mm drill Guide for 3.5 screws the drill guide (111-203 for Ø 3.5 mm screw) to the desired depth. *Instruments for Ø2.8mm screw are provided separately. 3.6 mm drill Guide for over-drilling & lag screwing With fixed angle drill sleeve (111-173), the locking screw can be inserted only in predefined or nominal angle. With variable angle drill sleeve...

Surgical Technique 4. Distal Screw Placement - continued Measure the screw length by using the depth gauge (111-086). Insert 3.5 mm locking or cortical screws by connecting the T10 driver (113-HF-616) to the driver handle (111-206). CAUTION: Use the maximum number of screws based on the indication to get the maximum stability Confirm screw placement under fluoroscopy. Required Instruments Depth Guide 111-086 ARIX Ankle System

Surgical Technique 5. Order of Screw Placement Insert most distal screw(❶) first, then one of proximal screws(❷) to prevent plate rotation. Then insert rest of screws as needed. Lateral Distal Fibula

Surgical Technique 6. Syndesmosis Screw (Optional) the surgeon decided to insert syndesmosis screws, a 3.5 mm If cortical screws can be utilized through the two oblong holes. Drill the screw hole with an angle of 30° anterior to target the center of the tibia. Measure the screw length and insert screw according to usual screw insertion steps. Confirm screw placement under fluoroscopy. Closing and postoperative protocol are at the discretion of the surgeon. WARNING: Screws placed across the syndesmosis have a higher probability of fatigue failure of screws due to the repetitive motion across...
