A 3D anatomical model saves a 4-year-old child from long-term complications of post septic arthritis destruction

In August of 2020, a 4-year-old child was diagnosed with Post Septic Arthritis Destruction and was ready to undergo surgery on his left proximal femur for hip reconstruction by femoral and pelvic osteotomies and abductor transfer. Septic Arthritis is extremely painful and can develop very quickly. It’s a very serious condition which can affect people of any age and needs to be treated in hospital as soon as possible as an emergency.

The physician sent Axial3D a model request for this patient to help them see the precise shape and length of the remaining femoral neck and greater trochanter. This new insight removed the previous uncertainty and the surgical team were able to proceed with full confidence on their refined plan.


The patient's family's understanding of the surgery and the resulting outcome became much easier to explain due to having a physical model in hand. In turn this made the consent process more informed and consensual.

As a further benefit, a significant amount of time was saved within the diagnosis of the patient and planning before this procedure. By having an exact plan of what would happen during the procedure, the physician was able to bring into surgery only the equipment that was necessary, saving money on the sterilization of these tools.

Post-operative recovery was extremely successful and fast for the 4-year-old child. The physician quoted to us, “I strongly agree with using 3D printed models as a way to improve surgical outcomes”. In the end, the model reassured the physician that his Plan A fixation would work. If the kit they keep in the hospital for these procedures was taken out as a loan kit (as it is in most hospitals) then this model would have prevented waste and money. The visualization of the anatomy was key to performing the correct osteotomy (the shaving or reshaping of bones) and to ensure that the physician could trial the angles of insertion beforehand.
