Customized Distal Tibial Cage
For cases with large bone defects from trauma or tumors, the customized distal tibia cages are designed to fit the intramedullary nail used by the physician and to replace the bone defect. They feature a porous structure for better osseointegration.
Product Overview
Product Overview
Before the advent of 3D printing technology, vascularized fibular transfer, allograft and autograft spacers, and the cumbersome method of moving bone pieces with external fixation and braces were used in cases of severe bone defects.
As the tibiotalar joint was damaged, an intramedullary hole was designed in the customized distal tibia cage to allow for the passage of the tibia-talo-calcaneal (TTC) nail to maintain postoperative compression across the joint surfaces.
However, customized distal tibial cages are designed based on the surgeon’s preoperative planning while taking into account the unique geometry of the patient’s bone and any defects that may be present. This leads to a great surgical outcome and reduced stress for the surgeon as everything has been determined preoperatively and conforming prostheses have been manufactured accordingly.
Workflow
Imaging
CT scan and X-ray imaging are acquired to create an accurate 3D model of the patient's lower extremity, and identify the extent of the defect.
Implant Design
Clinical engineers design a custom implant based on the patient's anatomy and the intramedullary nail being used.
Product Manufacturing
Upon physician approval, the implant is manufactured using 3D printing technology.
Surgery
The sterilized implant is delivered to the attending physician along with an anatomical model of the patient. A company representative may be present in the operating room to assist with cage placement.
Specifications
Surgeons can collaborate with the engineering team to design the implant’s geometry and features based on their clinical assessment of the patient and the intended treatment plan.
At the interface between the bone and the prosthesis, it is possible to have a TPMS lattice structure such as a gyroid, to promote bone ingrowth as a secondary mechanism of fixation.
The prosthesis is designed based on the axial geometry of the bone shaft to fit perfectly on the bone and promote osseointegration.
The height of the cages is made according to the opposite limb to prevent limb shortening.
