Introduction:

Complex distal femur fractures AO/AOT type 33C3.3 constitute a challenge for orthopedists due to the difficulty of their treatment and associated complications. The surgical planning and procedure use condylar plates; but these are associated with loss of fixation and collapse of the reduction.

Objective:

To describe preoperative planning for an AO/AOT 33C3.3 distal femur fracture with 3D bioprinting and computer reconstruction.

Case report:

The case of a 34-year-old male patient is reported. He has comminuted left fracture of the distal femur, AO/AOT type 33C3.3, due to a traffic accident. Surgical planning and treatment were successfully performed with 3D biomodel printing and reconstruction. Based on the patient's tomographic images, the main fragments, the reduction sequence, the number and position of the implants to be used were identified.

Conclusions:

Preoperative planning is a critically important stage in managing complex fractures. Conventional techniques can be optimized with computer-assisted surgery and reconstruction with 3D printed biomodels. This novel proposal will allow the appropriate use of materials, optimal reduction sequence, better stability of the fracture and lower risk of surgical complications.
