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...

Background:

Accurate localization of rib fractures is critical for successful surgical stabilization of rib fractures (SSRF).
Mixed reality (MR) technology offers potential for real-time anatomical imaging overlay, aiding fracture visualization and incision planning.
This pilot study investigated the feasibility of MR for rib fracture localization in SSRF.

Purpose of the Study:

To assess the feasibility of using mixed reality (MR) technology for precise rib fracture localization in the context of surgical stabilization of rib fractures (SSRF).
To evaluate the performance of MR in identifying rib fractures compared to traditional methods.
To identify technical challenges and areas for improvement in MR systems for surgical applications.

Main Methods:

A pilot study involving a pre-clinical phase (2 healthy patients) and a clinical phase (6 patients undergoing SSRF).
CT scans were converted into 3D holographic models and projected onto patients using Microsoft HoloLens2 (HL2) after anatomical calibration.
Key metrics assessed included hologram projection stability, fracture identification, time taken for marking, and skin-to-fracture displacement.

Main Results:

Stable and accurate hologram projection was achieved in both study phases.
MR identified 54 rib fractures, including subscapular fractures, compared to 30 identified by ultrasound (US).
Mean fracture marking time was 9.07 minutes for MR vs. 10.02 minutes for US; mean displacement was 2.89 cm for MR vs. 2.04 cm for US.

Conclusions:

Mixed reality (MR) technology is feasible for surgical stabilization of rib fractures (SSRF), enhancing the visualization of rib fractures.
The study identified technical limitations, such as distorted surface anatomy and positional variations, that need to be addressed.
Further development is necessary before MR can be widely implemented in clinical practice for SSRF.
