Brief Summary:
The immediate goal of the proposed research is to test the value of a new low-cost, low-dose standing CT system for efficient early detection of both joint degeneration and elevated contact stress. The standing CT scanner holds promise for detecting arthritic changes earlier than other imaging modalities because of the combination of its 3D nature and ability to image joints in a weight-bearing pose. A secondary goal of the proposed research is to enable predictive models for osteoarthritis risk based on measures of post treatment contact stress, both to inform treatment and so that new interventions can be tested in a manner incorporating risk stratification.

Condition or disease Intervention/treatment Phase
Orthopedic Disorder Trauma Ankle Fractures Post-traumatic Osteoarthritis Radiation: pedCAT Not Applicable

Detailed Description:
Individuals who present with an intra-articular of the tibial plafond will be consented to participate in this study. We will obtain pedCAT scans at 6, 12, and 18 months post-injury, as well as several questionnaires that will be administered during the clinical visits. We will also review the subjects' electronic medical record for data related to the injury, including the timing and mechanism of injury, time from injury to surgery, length of hospital stay, any complications and/or subsequent ankle surgeries, as well as any clinic notes, imaging, and/or outcomes scores related to the calcaneus fracture.

Arm Intervention/treatment
Experimental: Experimental: pedCAT
Subjects in this group will undergo weight-bearing CT (pedCAT) imaging at 6 months, 12 months, and 18 months post-ankle injury.
Radiation: pedCAT
Weight-bearing CT scan (pedCAT) of ankles to measure 3D joint space width following ankle fracture.

Primary Outcome Measures :
  1. Changes in the ankle joint space width [ Time Frame: 18 months ]
    Tracking longitudinal changes in the 3D joint space width as seen in pedCAT imaging compared to baseline pedCAT imaging

Secondary Outcome Measures :
  1. Change in ankle pain [ Time Frame: 18 months ]
    Subjective measure of foot and ankle pain gathered by patient reported outcomes questionnaires

  2. Change in ankle function [ Time Frame: 18 months ]
    Subjective measure of foot and ankle function gathered by patient reported outcomes questionnaires
