Abstract
Study design: Cadaveric investigation.
Objective: Rigid internal fixation (RIF) using plates and screws is often not feasible in low and middle-income countries due to limited resources. Interosseous wiring to achieve semi-rigid fixation is often used, but lacks biomechanical force data. Herein we aim to quantitatively compare interosseous wiring to RIF.
Methods: Cadaveric mandibles were fractured at the parasymphysis and angle. Fixation was achieved using interosseous wiring in both single wire loop and figure-of-eight formations, as well as plate and screw fixation (n = 5 for each fixation type at each fracture site). A force gauge was used to measure the number of Newtons (N) required to achieve diastasis and complete failure at the fixation site.
Results: For angle fractures, the mean force required for initial diastasis was 4.1, 5.9, and 10.9 N for single wire, figure-of-eight wiring, and plating respectively (P < .001). Complete failure was achieved with 152.9, 168.9, and 237.6 N of force for the three methods, respectively (P < .001). Complete failure was achieved for parasymphyseal fractures with 197.7, 263.0, and 262.8 N of force for single wire, figure-of-eight wiring, and plating respectively (P = .002). Forces to achieve initial diastasis for parasymphyseal fractures were not statistically significant among the three fixation methods (P = .29).
Conclusions: Figure-of-eight interosseous wiring resists comparable forces across mandibular fractures compared to the gold standard of plating. In resource-limited settings when plates and screws are not available, this technique can be considered to achieve semi-rigid fixation of mandibular fractures.
期刊介绍:
Human Studies is an international quarterly journal dedicated primarily to take forward and enlarge the dialogue between philosophy and the human sciences. Therefore the journal addresses theoretical and empirical topics as well as philosophical investigations in different areas of the human sciences. Phenomenological perspectives and hermeneutical orientations, broadly defined, are the primary focus and frame for published papers. The journal benefits from scholars working in a variety of fields and who seek a forum to address these issues, in order to bridge the gap between philosophical and other modes of inquiry in the human sciences. Considering this as the main conceptual aim of Human Studies its wide-ranging interdisciplinary coverage includes contributions from sociology, philosophy, psychology, political science, communication studies, social geography, anthropology, history, and qualitative social research (especially ethnomethodology). A particular accent is set upon communication possibilities between these different perspectives. Thus, interdisciplinary approaches using phenomenology as starting point and reference in trying to analyze and explain the social reality are encouraged and welcome. Both established lines of interpretation and contemporary questions can be used either as basis or subject-matter. Human Studies is the official journal of the Society for Phenomenology and the Human Sciences (SPHS).
