Ankle Fracture vs Ankle Fracture-Dislocation

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.

Inclusion Criteria:

- Patients who sustain an isolated bi-malleolar or trimalleolar ankle fracture or an
ankle fracture-dislocation requiring open reduction internal fixation

- Patients ages 18 and over

- The subject is psychosocially, mentally, and physically able to understand and comply
with the requirements of the study

- Open and closed fractures (excluding Gustilo grade 3)

- English must be patient's primary language

Exclusion Criteria:

- Previous injury or significant osteoarthritis to the affected ankle

- Current ipsilateral or contralateral lower extremity injury with the exception of a
contralateral ankle fracture or fracture-dislocation

- Retained hardware from a previous injury at or around the tibia-talar joint of the
affected extremity

- Patients under the age of 18

- History of inflammatory arthropathy

- Traumatic Brain Injury or Spinal Cord Injury preventing weightbearing on the lower
extremities

- The subject has another concurrent physical or mental condition that is likely to
affect compliance with the study requirements

- Patients with Gustilo grade 3B and 3C open fractures
