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 HeightIncreaseInfo (HII), Precice internal lengthening is performed under strict orthopedic supervision with a customized lengthening protocol designed for each patient.
Mechanism of Precice Internal Lengthening
A motorized intramedullary nail is surgically inserted inside the bone.
The device contains a small internal magnetic motor.
An External Remote Controller (ERC) activates the nail externally.
The nail lengthens gradually according to the surgeon’s prescription.
Controlled distraction allows natural bone regeneration.
Benefits of Precice Nail Lengthening
No external fixator required
Lower infection risk (no pins or wires)
Greater patient comfort
Highly precise magnetic-controlled lengthening
Gradual distraction with minimal pain
Because the lengthening is extremely controlled and gradual, pain during the distraction phase is typically minimal.
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
Femoral Internal Nail Insertion Methods
Antegrade Insertion
Nail inserted from the top of the femur near the hip.
Retrograde Insertion
Nail inserted from the lower end of the femur near the knee.
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.
