Internal Lengthening Technology

Precice Nail Lengthening

Precice Nail Lengthening, also known as internal lengthening, is an advanced limb lengthening technique that eliminates the need for bulky external frames. The device is inserted inside the bone canal and gradually increases bone length using controlled magnetic technology.

At Height Increase Info (HII), Precice internal lengthening is performed under strict orthopedic supervision with a customized lengthening protocol designed for each patient.

How It Works

Mechanism of Precice Internal Lengthening

01

A motorized intramedullary nail is surgically inserted inside the bone.

02

The device contains a small internal magnetic motor.

03

An External Remote Controller (ERC) activates the nail externally.

04

The nail lengthens gradually according to the surgeon’s prescription.

05

Controlled distraction allows natural bone regeneration.

Advantages

Benefits of Precice Nail Lengthening

No External Fixator

The internal nail eliminates the need for external frames, improving mobility and patient convenience.

Lower Infection Risk

No pins or wires passing through the skin significantly reduce infection risk compared to external fixators.

Greater Comfort

Patients experience improved comfort during recovery due to the fully internal lengthening mechanism.

Precise Magnetic Control

The nail lengthens through a magnetic motor controlled externally by the surgeon’s programmed settings.

Gradual Distraction

Lengthening occurs gradually and precisely, allowing soft tissues and bone to adapt naturally.

Because the lengthening is extremely controlled and gradual, pain during the distraction phase is typically minimal.

Eligibility & Restrictions

Requirements for Precice Nail Surgery

  • Bone canal diameter must be wide enough to fit the nail
  • Sufficient bone length for safe insertion
  • Healthy bone quality
  • No uncontrolled systemic conditions
  • MRI scans may be restricted after nail insertion
  • ERC device produces sound during activation
  • Weight bearing is partial and surgeon-controlled
  • Strict adherence to physiotherapy is required
Insertion Techniques

Femoral Internal Nail Insertion Methods

Antegrade Insertion

The intramedullary nail is inserted from the upper part of the femur near the hip joint. This technique allows the nail to pass through the natural canal of the femur from the proximal end.

Retrograde Insertion

The nail is inserted from the lower end of the femur near the knee. This approach is commonly used when surgical access from the distal femur provides better alignment control.

The choice of insertion technique depends on limb anatomy, surgeon preference, and patient-specific biomechanical considerations.

Weight Bearing & Recovery Guidelines

  • Weight bearing is partial and gradual.
  • Allowed load depends on the diameter of the nail used.
  • Progression is prescribed strictly by the surgeon.
  • Physiotherapy is essential to maintain joint mobility.

At HII, Precice internal lengthening is performed with structured planning, precision monitoring, and comprehensive rehabilitation to ensure safe and predictable height gain.
