Dr. Manish Agarwal, India’s leading Onco Orthopedic surgeon in Mumbai, Maharashtra being a pioneer in treated tumor bone/ECRT aided surgeries studied medical history, imaging and histopathology reports. It was decided to proceed with ECRT line of treatment. The challenge was to salvage growing epiphyses in this 7 year-old boy’s femur thus using patient specific cutting guides and patient specific femur implant. Incredible team discussed with Dr. Agarwal, the designing and entire manufacturing process. It was initially started with surgical planning and case simulation with the help of US FDA & CE approved Materialise Mimics software by superimposing CT & MRI DICOM data & Anatomical Model. As Anatomical model maintained 1:1 ratio with the anatomy, hence showed excellent detailing of the defect, the model was also used to design jigs & implant on actual bone, which further helped the pre surgical planning. Once the planning was finalized, the surgery was accompanied with not only Customized Implant but also Cutting guides & Jigs. Read more

Customized Jig helped in precise cutting of bone tissue, and are manufactured using biocompatible Nylon material which is autoclavable. The design was completed with valuable inputs between the doctor and the Incredible design team together. The benefits of a 3D printed implant was its customization which resembled not only the anatomy but also gave a perfectly fitting implant. The variable sizes helped in strengthening the particular area required. Finite Element Analysis was carried out which to determine the strength, stability and functionality of the implant. The specialty of the design was the pre-planned screw trajectory which was defined by surgeon team to avoid physes and to achieve maximum bone purchase. Excellent combination of combi and locking holes provided to ensure strong and stable hold of bone fragment. Read less
