Transverse Tibial Bone Transport (TTT) in the Management of Chronic Diabetic Lower Extremity Wounds
This study is testing a new treatment for chronic, hard-to-heal wounds on the legs and feet caused by poor blood flow (ischemia) and diabetes. The treatment, called Transverse Tibial Bone Transport (TTT), involves a surgical procedure that uses a device to slowly move a piece of bone in the lower leg, which may help grow new blood vessels and improve healing. The trial is currently recruiting participants and is taking place in Jacksonville, United States. It will evaluate how well wounds heal and whether limbs can be saved in patients who have few other options. This research matters because diabetic foot ulcers are a leading cause of amputation, and many patients do not respond to standard treatments like wound care, offloading, and medications. In China, TTT and similar bone transport techniques are already used at some specialist centers, so this trial may confirm their benefits and help make them more widely available. The study uses a device called Biodynamik XT3.
Key takeaways
- The trial is testing a surgical technique called Transverse Tibial Bone Transport (TTT) that may stimulate new blood vessel growth in the leg, potentially healing wounds that haven't responded to other treatments.
- For patients with chronic diabetic foot ulcers and poor circulation, this approach could offer a chance to avoid amputation, but it is still under study to confirm its safety and effectiveness.
- The study is recruiting at a single location in Jacksonville, United States, so international patients would need to travel there to participate.
- Ask your doctor: Is TTT or a similar bone transport procedure available at your center? Would you be a candidate? What are the risks and recovery time?
- This trial may help validate a technique that is already used in some Chinese hospitals, potentially leading to broader acceptance and insurance coverage.

Editor's note
This treatment aims to solve the problem of poor blood flow in your leg, which is often why diabetic wounds don't heal. By gradually moving a small piece of bone in the shin, it tricks your body into growing new blood vessels around the area, bringing oxygen and nutrients to the wound. If your wound hasn't healed with standard care, or if amputation has been mentioned, this could be a limb-saving option worth exploring—it's designed for exactly that situation. In China, TTT and similar bone transport techniques are already available at some specialist DFU centers, so you might not need to travel abroad. If you're considering overseas treatment, ask if the procedure is offered locally first, and discuss with your doctor whether you're a suitable candidate.
