What is the rating for immobility of the hip where the arc of motion is 0 - 60 degrees?

What is the rating for immobility of the hip where the arc of motion is 0 - 60 degrees?

• A. 10%
• B. 23%
• C. 30%
• D. 40%

Answer: (B)

The key idea is that hip impairment ratings based on immobility use the actual arc of motion measured in degrees. The impairment table assigns a specific percentage to each range of motion. An arc of motion from 0 to 60 degrees falls into the category that corresponds to a 23% impairment. So, even though some movement remains, the limited 0–60° arc is what places the hip at 23% impairment. The other percentages would align with different, either greater or smaller, motion ranges on the table, not with a 0–60° arc.
