Fractures: Bone Repair

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Area of Science:

Biomedical Engineering
Oral and Maxillofacial Surgery
Additive Manufacturing

Background:

Severe mandibular avulsion injuries present significant reconstructive challenges.
Traditional reconstruction methods may have limitations in achieving optimal functional and aesthetic results.

Observation:

A 25-year-old male patient sustained a near-total mandibular avulsion due to a gunshot injury.
The patient's defect was reconstructed using a patient-specific, three-dimensional (3D) laser-printed titanium implant.

Findings:

The 3D laser-printed titanium mandible was successfully implanted, restoring masticatory function.
The implant cavity was filled with the patient's bone fragments and iliac crest bone graft, covered by periosteum.
The procedure was described as fast and predictable, yielding excellent aesthetic and functional outcomes.

Implications:

Three-dimensional laser printing offers a viable and effective solution for complex craniofacial bony reconstruction.
This technology represents a significant advancement in treating severe facial trauma and congenital defects.
The future of craniofacial reconstruction is likely to involve increased utilization of additive manufacturing techniques.
