Brief summary

The goal of this observational study is to compare two localization methods used before surgical stabilization of rib fractures (SSRF): mixed reality (MR) and ultrasound-guided. Main Research Question Before SSRF, does MR help surgeons mark rib fracture locations more accurately (in centimeters) and faster than ultrasound-guided? Participants After the study ends, all participants will keep follow-up at the thoracic surgery clinic. The team will record wound healing and pain scores for use in the observational study.

Design outcomes

Primary

Measure	Time frame	Description
Rib fracture localization accuracy (cm)	Intraoperative assessment during the index SSRF procedure (immediately after fracture exposure and before plate fixation).	Definition: For each participant and each method (mixed reality \[MR; OpVerse\] and ultrasound), accuracy is the absolute linear distance (cm) between the preoperative skin mark and the intraoperatively identified center of the fracture after exposure. Measurement: After skin incision and minimal soft-tissue dissection to expose the fracture line, the surgeon measures the shortest distance from the skin mark to the fracture center with a sterile ruler, recorded to 0.1 cm. Analysis note: Accuracy will be summarized per method, and a within-subject difference (MR minus ultrasound) will be calculated. Procedural note: If exposure is inadequate, the incision may be extended at the surgeon's discretion to safely perform SSRF; this does not change the measurement definition.
