Design outcomes

Primary

MeasureTime frameDescription
Visual Analog ScorePostoperative hour 3Patient reported pain score from zero to ten where zero is no pain and ten is the most pain
Evidence of motor blockPostoperative hour 3Patient reported yes/no answer to survey question: Are you able to wiggle your toes?

Secondary

MeasureTime frameDescription
Neuralgia symptoms: survey questionPostoperative week twoPatient reported yes/no answer to survey question: Have you had any signs of neuralgia, such as persistent numbness, tingling, or increased sensitivity in your foot or ankle that you feel is not at the surgical location? 1 = yes, I have had signs of neuralgia; 2 = no, I have not had signs of neuralgia.
Pill countPostoperative week 2Patient reported fill-in-the-blank answer to survey question: Total number of pain pills taken during this time.
