Ankle Fracture vs Ankle Fracture-Dislocation

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to compare outcomes of patients with an ankle fracture to those with ankle fracture-dislocations. We hypothesize that long-term clinical outcomes for patients sustaining ankle fracture dislocations are poorer than those without dislocation.

Detailed Description
-----------------
Orthopaedic literature has very limited data regarding outcomes following ankle fracture dislocations. Increased knowledge of the long-term consequences of these injuries could usher in changes to treatment paradigms, potentially resulting in improved outcomes. Thirty patients will be enrolled into two arms of this prospective study: isolated ankle fractures and ankle fracture dislocations. Patients will be followed through their operative and postoperative course and clinical and radiographic assessments will be analyzed. We plan to compare the clinical, radiographic, and functional outcomes of patients with ankle fractures to those with ankle fracture-dislocations. We also plan to identify factors that contribute to or predict poor clinical, functional, and/or radiographic outcomes in patients with ankle fractures and fracture-dislocations.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Functional Outcome | Clinical and functional outcomes will be measured using the Foot and Ankle Ability Measure (FAAM) and the Short Form Musculoskeletal Functional Assessment (SMFA). Radiographic analysis will be performed to determine nonunion, malunion, joint space incongruity, hardware failure/loosening, and/or severity of osteoarthritis. The Van Dijk grading scale will be used for radiographic assessment. | 6, 12, and 24 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Radiographic Outcome | Radiographic analysis will be performed to determine nonunion, malunion, joint space incongruity, hardware failure/loosening, and/or severity of osteoarthritis. The Van Dijk grading scale will be used for radiographic assessment. | 24 month |
