Primary Subtalar Arthrodesis for Calcaneal Fractures

Primary Outcomes (4)

• Return to Work/Duty - Metabolic Equivalent for Tasks (METs) Score

  The primary outcome is return to work/duty as measured by the International Physical Activity Questionnaire (IPAQ). The IPAQ is a validated, self-report measure that captures detailed information about participation in a wide range of physical activities, including the number of days and amount of time spent in the previous 7 days. Responses for each type of physical activity are then transformed into the number of Metabolic Equivalent for Tasks (METs), and a METs/week is calculated for each patient. The IPAQ has moderate concordance with accelerometry-measured METs in an orthopaedic injury patient population. (one MET is defined as 3.5 mL O2 uptake/kg per min, which is the resting oxygen uptake in a sitting position). Less than 5 METS is poor, 5-8 METS is fair, 9-11 METS is good, and 12 METS or more is excellent.
