Summary
Comminuted midshaft clavicle fractures often feature coronal plane breaks and anterior/inferior fragments. Posterior-superior cortical contact aids surgical reduction in these clavicle fractures.
Area of Science:
- Orthopedic surgery
- Traumatology
- Radiology
Background:
- Parametric analysis of clavicle fracture morphology is lacking in existing literature.
- This study addresses the descriptive features of comminuted midshaft clavicle fractures in surgically treated patients.
Purpose of the Study:
- To characterize the morphology of comminuted midshaft clavicle fractures.
- To identify key features guiding surgical reduction in these fractures.
Main Methods:
- Retrospective evaluation of 117 consecutive patients with acute displaced midshaft clavicular fractures.
- All patients underwent open reduction and internal fixation.
- Collection and analysis of radiographic and surgical data, including 3D CT imaging.
Main Results:
- Fractures were classified as AO type B (39) and type C (78).
- Coronal plane fracture lines were present in 88.89% of patients on 3D CT.
- Anterior/inferior fragments were common (80.34%), with a constant segment for reduction identified in 87.18% of cases.
- Cortical contact in the posterior-superior quadrant facilitated reduction in 96.08% of cases where anatomic reduction was achieved.
Conclusions:
- Comminuted midshaft clavicle fractures commonly exhibit coronal plane fracture lines.
- Fragments are predominantly located anteriorly or inferiorly.
- Posterior-superior cortical contact serves as a reliable landmark for guiding anatomic reduction.
