METAFIX
Metatarsal Lengthening 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
Latent Phase: 5–7 days post-corticotomy.
Lengthening Phase:
Daily adjustments (0.25 mm × 2 or 0.5 mm × 1).
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.
