Comparative Overview of Limb Lengthening Methods

Explore Our Limb Lengthening Innovations

Limb lengthening surgeries have evolved over time, offering innovative methods to address bone length disparities. This article provides a brief comparison of prominent limb lengthening techniques, emphasizing both internal and external approaches.

From the traditional Ilizarov method to the advanced STRYDE and PRECICE 2 systems, each method has its unique characteristics and benefits.

Ilizarov Method:

The Pioneer in Extra-Bone Limb Lengthening Surgery The Ilizarov method, the pioneering technique in bone lengthening, involves the use of thin wires and circular external fixator devices.

By securing the bone, these components prevent rotation and misalignment, marking a foundational approach to addressing limb length differences.

LON Method:

Internal Nails for Lengthening Over Nails In the LON Method, bones are distracted using a monolateral external fixator device, and the lengthening occurs over internal intramedullary nails.

This approach allows for the removal of external devices approximately 3-4 months post-surgery, while the intramedullary nails remain in place for 1-1.5 years to ensure complete consolidation and healing.

STRYDE and PRECICE 2:

Innovations in Intra-Bone Limb Lengthening The STRYDE method, an advanced version of PRECICE 2, represents the latest limb lengthening system.

Employing internal intramedullary nails, both systems boast reduced pain levels compared to external fixator methods like LON, Holyfix, and Ilizarov. STRYDE introduces various innovations, enhancing patient comfort during the recovery process.

Holyfix Method:

Accelerated Bone Formation with External Fixation Holyfix stands out in Extra-Bone Limb Lengthening Surgery, utilizing monolateral external fixators attached by pins to secure bones.

The apparatus facilitates accelerated bone formation while strategically transferring the burden from the bone without inducing any shortening. The external fixator device in Holyfix shares similarities with the LON method, but the key distinction lies in the absence of internal intramedullary nails.

The diverse limb lengthening methods cater to different patient needs, considering factors such as pain tolerance, recovery time, and internal versus external fixation.

From the time-tested Ilizarov method to the cutting-edge STRYDE and PRECICE 2 systems, each approach contributes to the field's ongoing progress, offering viable solutions for individuals seeking limb length correction.

Patients and healthcare professionals can make informed decisions based on the specific advantages and considerations of each method.
