Brief 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).

Outcome Measures

Primary Outcomes (3)

  • Patient Reported Outcome of Pain

    Patients will self-report pain using a numeric pain rating scale (NPRS), 11-point numeric scale. 0 = No pain and 10 = Worst Possible Pain

    Week 6 to week 52

  • Patient Reported General Health State

    General Health State will be measured using the CDC HRQOL question 1, categorized into excellent, very good, good, fair, and poor.

    Week 6 to week 52

  • Patient Functional Health Score

    Olerud and Molander Scoring System is a 9 question self-assessment of pain, stiffness, swelling, ability to climb stairs, run, jump, squat, use of supports, and work/activities of daily life. A total score of 100 is calculated, with 100 equaling best.

    Week 6 to week 52

Secondary Outcomes (1)

Study Arms (2)

Standard of Care

ACTIVE COMPARATOR

Standard of care imaging techniques (3D CT scan and plain film radiographs) will be obtained for the surgeon to pre-operatively plan the surgery.

Other: 3D CT scanOther: Plain film radiographs

Intervention

EXPERIMENTAL

A 3D printed plastic model prototype will be developed for the surgeon to use, in addition to the standard of care imaging techniques (3D CT scan and plain film radiographs), to pre-operatively plan the surgery.
