#SRHaccess Facebook LIVE Recap: Limb Lengthening Devices

On this week’s Facebook live, Division Director Alex Cherkashin, M.D.* and Co-director of the Center for Excellence in Limb Lengthening David A. Podeszwa, M.D. joined us to discuss the devices used for limb lengthening and reconstruction. Below is a recap of the conversation.

History of the Ilizarov device 
The original Ilizarov external fixator system has been around for about 60 years ago as a form of treatment to lengthen limbs and correct deformity. The external fixator has evolved to become more comfortable and easier for the patient to use/handle while wearing it.  

How has the device evolved?
  • TRUE/LOKTM: first generation developed from Scottish Rite Hospital as a different iteration of the original Ilizarov equipment. It is more comfortable for the patient and easier for the surgeon to apply. 
  • TL-HEX: the most advanced external fixation system involving six struts to allow for more flexibility and precise adjustments for correction.
Most common conditions where the external fixator is used: 
  • Congenital conditions of limb length differences or deformities
  • Post traumatic injuries
  • The Ilizarov method was initially used for lengthening. However, through the years of innovation, the device has evolved to be a form of treatment for correction of limb deformity. 
  • If bones or joints need correction, the external fixator provides the best results. 
Research: Center for Excellence in Limb Lengthening 
  • Cherkashin is a member of the hospital’s research team. Most of his work involves developing the software that builds these devices. 
  • The center’s research revolves around improving the devices, patient outcome studies and analyzing clinical results of patients who undergo this treatment.
Experts who travel the world
  • Members for our Center for Excellence in Limb Lengthening travel world-wide to train orthopedic surgeons on applying the external fixator. 
  • The equipment continues to become more complicated and proper education is necessary for best results in treatment for the patient.
