Custom Ankle Fusion Cages

Custom ankle cages are specialized implants designed for patients with talar avascular necrosis (AVN), tailored to each patient’s unique anatomy. These implants improve patients’ satisfaction with great surgical outcomes through the use of biocompatible medical-grade materials and cutting-edge 3D printing technology. The following conditions warrant the utilization of these cages: avascular talus necrosis, severe arthritis [1], traumatic fractures, and Charcot deformities [3].

Product Overview

Product Overview

Since every patient’s anatomy is unique, off-the-shelf cages limit the surgeon’s choice for a treatment plan, while customized cages are created based on the physician’s ideal treatment plan, which results in higher-quality care for the patient.

In order to ensure optimal compliance with the patient’s anatomy and the physician’s treatment plan, custom ankle cages are designed based on patient CT scans, accounting for the possibility of larger bone necrosis during the design and manufacturing process.

The likelihood of a successful surgical result is greatly increased when biocompatible medical-grade materials and state-of-the-art 3D printing technology are used in the production of these cages with special porosity design based on surgeon’s preference.

For patients with avascular bone necrosis, Tibotalocalcaneal Arthrodesis [1] or Charcot ankle deformity [3]; these cages are the best option since they do away with the requirement for prefabricated, one-size-fits-all designs, which frequently necessitate alterations and adjustments to the cage and the fusion intramedullary nail and also limit the treatment plan options available to physicians.

Workflow

Step 1

Imaging

To match the existing deficiency without the need for future bone reduction, a realistic 3D model of the patient's anatomy is generated using CT and Xray imaging.

Step 2

Cage Design

Considering the patient's anatomy and soft tissue features, biomedical engineers create a tailored cage.

Step 3

Product Manufacturing

3D printing technology is used to construct the cage with titanium, cobalt-chrome, and tantalum when a doctor gives permission to proceed.

Step 4

Surgery

Anatomical model of the patient and the sterilized cage are given to the physician. An employee of our company may serve in the operating room to help with cage placement.

Specifications

Based on the clinical evaluation of the patient and the desired course of therapy, surgeons and the engineering team can work together to develop the shape and features of the cage.

In addition to intramedullary nails, to encourage bone ingrowth and osteointegration for the better secondary stability, the base structure of the spherical cage may incorporate a TPMS lattice structure, such as gyroid.

Personalized cages allow for the customization of any design according to the doctor’s preferences, and the inclusion of a truss-based lattice which is filled with autograft, reduces the possibility of non-union.

Based on the intended nail size used by the surgeon, we manufacture the intramedullary canal size.

We create modular cages that are tailored to the one-of-a-kind anatomy of the patients with the deformity or issue in their distal tibia. [2]
