Fractures: Bone Repair01:27

Fractures: Bone Repair

4.5K
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...

Sutures of the Skull01:22

Sutures of the Skull

9.5K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Summary

Rigid fixation from prior orthognathic surgery may complicate subsequent facial trauma. A broken titanium plate worsened a zygomaticomaxillary complex fracture, highlighting concerns about long-term implant effects.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Trauma Surgery
  • Biomaterials Science

Background:

  • Rigid fixation is standard for orthognathic surgery stabilization.
  • The long-term necessity and fate of these implants remain debated.
  • Routine removal of rigid fixation is not universally established.

Observation:

  • A 26-year-old male with prior two-jaw surgery experienced high-velocity facial trauma.
  • CT revealed a zygomaticomaxillary complex fracture.
  • Intraoperative findings included a fractured L-shaped titanium plate with associated bony fragments.

Findings:

  • The pre-existing rigid titanium fixation may have contributed to fracture comminution.
  • The broken plate potentially exacerbated the severity of the traumatic injury.
  • This case raises questions about the mechanical behavior of rigid implants under secondary trauma.

Implications:

  • Consideration of pre-existing rigid fixation is crucial in managing secondary facial trauma.
  • The potential for implant failure and fracture comminution warrants further investigation.
  • This case suggests a need to re-evaluate long-term management protocols for orthognathic surgery implants.
