MicroLift® Translation Fixator

MicroLift® is a translation fixator within the Smart Fixator® – Hexapod System product family. It provides controlled, single-axis transverse movement of a bone segment, including a cortical bone flap of the tibia or a segment of the fibula.

In tibial transverse transport (TTT), also called tibia transverse transport or tibial cortex transverse transport, a surgically prepared tibial cortical segment is moved gradually along a transverse axis. MicroLift® provides the mechanical control for this movement, with 0.25 mm adjustment increments and up to 15 mm of transport.

For tibial bone transport and fibular bone transport applications, MicroLift® controls transverse movement of the selected bone segment. Fibular transverse transport, also described as transverse fibular transport or transverse fibular bone transport, uses a segment of the fibula. The fixation configuration and transport plan are selected for the individual case within the system’s indications for use.

MicroLift® can be used independently with half-pin fixation or combined with the hexapod or circular fixator components of the Smart Fixator® – Hexapod System to form a hybrid frame. In hybrid applications, the rings can be connected to the bone using half pins or K-wires.

The Smart Fixator® – Hexapod System’s indications include correction of bony or soft tissue defects and deformities. Refer to the applicable Instructions for Use for the complete indications, contraindications, warnings and precautions.

The closed transport housing minimizes mechanical play, and the predefined linear distraction axis limits off-axis loading. The enclosed body also reduces the risk of soft tissue irritation from external contact.

Each click produces 0.25 mm of distraction or compression. The adjustment knob automatically locks after each increment to prevent unintended movement.

The 3.0 mm transport segment half pins are positioned in a V-shaped configuration to reduce the risk of pull-out and enhance fixation stability.

In a biomechanical study of a monolateral fixator model, converging pin pairs formed the stiffest construct (Klemeit et al., Bioengineering 2023).

15 mm maximum transport capacity within a compact device footprint. A marked transport module allows visual confirmation of the total transport distance.

Directional markings (UP/DOWN) indicate distraction or compression, and numerical indicators (1–4) assist the patient in tracking the prescribed daily adjustments.

A plastic safety clip engages designated grooves on the fixator body to prevent unintended disengagement of the transport module during the distraction phase.

This product is CE-marked and has also been cleared by the FDA for distribution in the United States (510(k) K263083).
