The applicant was seriously injured in a motor vehicle accident, resulting in a through-the-knee amputation of his right leg.
He applied for a catastrophic impairment designation under paragraph 2(1)(f) of the Statutory Accident Benefits Schedule, claiming a whole person impairment (WPI) of 55% or more.
The arbitrator evaluated the applicant's physical, skin, and mental/behavioural impairments using the AMA Guides.
The arbitrator found that the applicant sustained a 37% WPI for his lower extremity, a 20% WPI for skin impairment, a 15% WPI for mental and behavioural disorders, and additional minor ratings for his low back, left knee, and left wrist/elbow.
Combining these ratings, the arbitrator concluded the applicant sustained a 62% WPI, meeting the threshold for catastrophic impairment.
