On Aug. 15, 2015, plaintiff Manasse Shenouda, 18, a college student, was driving east on Golden Trails Street, in Ontario, when his vehicle entered the intersection with South Turner Avenue and was struck by a vehicle operated by Barry Knutson, who was attempting to turn left onto Golden Trails Street from South Turner Avenue. Manasse claimed to his back, left shoulder, left thumb, left wrist and left arm. Manasse sued Knutson, alleging that Knutson was negligent in the operation of his vehicle. Manasse claimed that Knutson failed to yield to oncoming traffic before entering the intersection. Defense counsel asserted that Manasse was comparatively at fault for the accident for entering the intersection while Knutson was making his turn., Manasse sustained an impingement of his left shoulder, and soft tissue to his left thumb, wrist and arm. He also sustained herniations at the L3-4 and L4-5 levels, as well as a bulge at the L5-S1 level. Manasse was taken by his brother to a hospital later that day. Although he had no thumb fracture, the thumb on his left hand was placed in a splint. Manasse later underwent MRIs and received chiropractic care. Manasse claimed that his were resolved by the time of trial. However, he alleged that he played football in high school and was active prior to the accident and that even though he was able to continue with school after the crash, he was physically impaired for two years. Manasse sought recovery of past medical costs, and damages for his past pain and suffering. Defense counsel questioned the reasonableness and amount of treatment that Manasse underwent.
