  Purpose

This prospective case series will essentially examine the influence of reduction quality on the primary functional outcome (as assessed using the FAAM) of patients with pilon fractures treated with plate fixation.

The plates used in this trial can be chosen according to the preferences of the surgeon.


Condition
Pilon Fracture of Tibia

Primary Outcome Measures:
  • Examine the influence of reduction quality on the primary functional outcome (as assessed using the Foot and Ankle Ability Measure (FAAM)) of patients with pilon fractures treated with plate fixation. [ Time Frame: 2 years ]
    The most important predictors of functional outcome after pilon fracture will be identified by evaluating the influence of radiologically assessed parameters of reduction quality and other factors (age, high/low energy trauma, AO fracture type, open/closed fracture, delay between trauma and definitive fracture fixation) on the FAAM. In parallel, the radiological parameters will also be validated with respect to their reliability.


Secondary Outcome Measures:
  • Surgical details [ Time Frame: 1 year ]
    • Length of surgery (skin-to-skin time)
    • Type of implant used
    • Use of bone graft
    • Soft tissue or wound-related procedures (eg, debridement, free flap, local flap, split skin graft)

  • Pre- and postoperative treatment [ Time Frame: 1 year ]
    Perioperative management data will include documentation of the use of thromboprophylaxis or prophylactic antibiotics, therapeutic antibiotics and pain medication including nonsteroidal antiinflammatory drugs (NSAID).

  • To assess whether patient and surgeon expectations are met with regard to the trauma outcome [ Time Frame: 1 year ]
    Trauma expectations factor (TEF) to assess the patient and surgeon expectations about the outcome of the treatment

Primary Completion Date: January 2017 (Final data collection date for primary outcome measure)
Detailed Description:
A prospective case series to examine the influence of reduction quality on the primary functional outcome (as assessed using the FAAM) of patients with pilon fractures treated with plate fixation. Radiological parameters including single/combined alignment and various articular measurements will also be validated according to their reliability. The sensitivity of the effects of reduction quality on functional outcome, and an extended evaluation of patient-rated functional and social outcomes as well as their outcome expectations will also be assessed as part of the secondary study aims.
