What Is A Total Talus Replacement? Total talus replacement is a surgical procedure performed for avascular necrosis of the talus. Avascular necrosis of the talus means that the talus bone (the bone in the center of the ankle) has lost its blood supply and is no longer alive.

Total talus replacements are a surgical treatment for talar avascular necrosis (AVN) replacing the entire talus. The potential for total talus replacements has increased with the advent of patient-specific implants using 3D printing based on computed tomographic scanning of the ipsilateral or contralateral talus.

Nov 9, 2023 · University of Florida Health recently joined the ranks of health systems nationally using a 3D printing technology that can build a new talus bone with a metal alloy to the exact specifications of a patient’s anatomy, allowing a faster recovery and providing a greater range of ankle motion after surgery, UF Health surgeons said.

MUSC Health performs its first 3D-printed talus replacement. by Carin Moonin The talus connects the lower leg and foot and is crucial for foot and ankle mobility. But compared to other nearby bones — the tibia, fibula and calcaneus — it receives relatively low blood supply. For this reason, it takes a long time to heal.

Jul 25, 2022 · What is ankle replacement surgery? Ankle replacement is a surgical treatment for ankle arthritis in which portions bone and cartilage in joint removed and replaced with prosthetic implants.

Bulk allograft transplantation takes bone and cartilage from a deceased donor (cadaver) and places it into the damaged talus. This surgery is reserved for severe cases of OLT that have either failed previous surgical treatment or involve a very large part of the talus. These types of OLTs may not respond to less invasive procedures.

We present our preferred surgical technique for talectomy and implantation of a custom talus for isolated TTR that articulates with the native tibial plafond. The most common indication for TTR is talar collapse due to avascular necrosis.

Introduction: The treatment of pathologic changes to the talus and surrounding joints presents a unique challenge to the foot and ankle surgeon.

A talar fracture is a break in the talus bone while talar extrusion is when the talus is fully pushed out due to high force trauma. Depending on the severity and the state of the talus, a reconstruction involving replacement of the talus may be appropriate to prevent further deterioration of adjacent

Jul 15, 2023 · Total talus replacement (TTR) is a surgical procedure which involves the removal of a pathologic talus and replacement with a patient-specific 3D-printed titanium (Ti) prosthesis coated with titanium nitride (TiN). DICOM data from a CT scan is used with specialized software to determine the size and dimensions of a TTR prosthesis.
