METAFIX Metatars Fixator

The METAFIX Metatarsal Lengthening Fixator by MEDINTERA (distributed globally via NAFX) is a cutting-edge external fixation system designed for safe, precise, and patient-friendly metatarsal lengthening. Below is a structured breakdown of its key features, clinical benefits, and technological innovations:

1. Core Advantages

• High Stability, Low Profile:

  • Compact, lightweight design (anodized aluminum/titanium) for biocompatibility, radiolucency, and minimal dorsal foot bulk.

  • Optimized rigidity for controlled distraction osteogenesis.

• Precision & Control:

  • Millimetric lengthening (0.25–0.5 mm/day) with modular clamps adaptable to various metatarsal lengths.

  • Targeted extension: 10–20 mm (up to 30 mm if needed).

• Patient Comfort:

  • Low-profile structure for daily activity compatibility.

  • Open-system design for easy pin care and wound monitoring.

2. Unique Innovations

A. Distal Synchronized Clamp Mechanism

• Protects the PIP joint during lengthening by synchronizing movement with the primary clamp.

• Prevents complications: Hyperextension, subluxation, or dislocation of toes (critical in pediatric/adolescent cases).

• Clinical benefit: Maintains toe alignment and joint integrity.

B. Multiplanar Angled Pin Placement

• Oblique/crossed pin insertion vs. traditional uniplanar fixation.

  • Reduces cortical splitting risk (especially in narrow/osteoporotic bones).

  • Avoids tendons, vessels, and soft tissues.

• Technical benefit: Enhanced pin stability and surgical flexibility.

3. Surgical Workflow

1. Latent Phase: 5–7 days post-corticotomy.

2. Lengthening Phase:

   • Daily adjustments (0.25 mm × 2 or 0.5 mm × 1).

3. Consolidation Phase:

   • Rigidity maintained for callus formation; radiological monitoring.

4. Clinical & Aesthetic Outcomes

• Functional restoration: Addresses brachymetatarsia, post-traumatic defects.

• Aesthetic improvement: Ideal for young female patients seeking foot balance/cosmetic enhancement.

5. Reliability & Compliance

• Manufactured by MEDINTERA (Turkey), distributed via NAFX.

• CE-certified, ready to use packaged, and globally validated.
