3D printed models have been a major player in Orthopaedics. Surgeons currently utilize 3D printing for:

  • Visualization of complex fractures

  • Selecting the right surgical equipment and implants.

  • Pre-contouring of fixation plates to better fit the patient's anatomy

3D printed bone models for visualization of fractures

A two year study was conducted by Bizzoto et al on articular fractures for trauma surgery. The study used 3D printed models to assist surgeons in visualising complex displaced fractures and deciding on treatment options. Sterilized models were also used for navigation and spatial orientation during the surgery. The study also reported that 3D models helped improve the patient’s understanding about his/her fracture.

Pre-contouring of fixation plates for a complex acetabular fracture

3D models printed from CJP were used to pre-contour fixation plates during this acetabular reconstruction surgery (University of New Mexico Health Science Centre). The OR time was reduced by 2 hours and the length of incisions required reduced from 12” to little as 4”.

Implant Sizing for joint reconstruction cases

3D models printed from patient-specific data can be used as reference for pre-operative implant sizing and selection  for joint reconstruction surgeries in total hip replacement and knee reconstruction cases.
