Comminuted Intra-Articular Distal Tibia Fracture Fixation Using Computer Techniques

Study Summary

Comminuted intra-articular distal tibia fractures (OTA 43-C) typically are the result of high-energy trauma such as motor vehicle collisions or fall from a height. They are complex injuries often associated with significant fragment displacement and severe soft tissue injury, a combination that has long challenged orthopedic surgeons. Traditionally, surgeons use plain film (X-ray) and CT scans (2 or 3 dimensional) to determine fracture pattern and displacement. Yet, in some cases, it is still difficult to identify the relationship among bone fragments, which often makes articular restoration challenging. As a result, patients with non-anatomic joint reconstructions have a higher rate of poor outcomes. The primary objective of this study will be to compare patient outcomes in two groups, one group who will receive enhanced pre-operative planning (3D printed plastic prototype + standard of care \[SOC\] imaging with 3D CT scan + plain film radiographs) and a second group who will receive pre-operative planning using SOC imaging alone (3D CT scan + plain film radiographs only). Patient outcomes collected throughout the 12 month post-operative period will include an assessment of radiographic fracture healing (union, non-union, malunion), pain using a Numeric Pain Rating Scale, Olerud and Molander Score based on patient's self-report, and development of complications (infection, wound healing, re-operation, and re-hospitalizations). The secondary objective of this study will be to evaluate whether utilizing an enhanced pre-operative plan with a 3D printed plastic prototype altered the original pre-operative plan based on SOC imaging alone (3D CT scan + plain film radiographs only).
