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.

Condition or disease
Ankle Fractures

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.

Primary Outcome Measures :
  1. Change in Functional Outcome [ Time Frame: 6, 12, and 24 months ]

    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.

Secondary Outcome Measures :
  1. Radiographic Outcome [ Time Frame: 24 month ]
    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.

Other Outcome Measures:
  1. Additional surgical procedures [ Time Frame: 2 years ]
    Documentation of any additional surgical procedures conducted on the affected ankle. Any surgical procedure will be noted. These may include debridement for infection or dehiscence, revision for hardware failure, arthroscopy, ankle arthrodesis, or cartilage restoration procedures.

  2. Postoperative Complications [ Time Frame: 2 years ]
    Postoperative complications will be documented and analyzed to determine if there are significant differences between the two groups. These will include infection requiring antibiotics or debridement, hardware failure, nerve or vascular injury, deep venous thrombosis, or revision surgery.
