What is the permanent disability percentage for a baker with a Colles fracture in his dominant hand showing grip strength readings of 65, 55, 60/107, 106, 105?

• A. 13%
• B. 14%
• C. 17.1%
• D. 18.2%

Answer: (A)

To determine the permanent disability percentage for a baker with a Colles fracture in his dominant hand, one would typically assess the grip strength readings in relation to the hand's functionality post-injury. The readings provided (65, 55, 60) compared against the normal strength readings (107, 106, 105) are essential for calculating the percentage of loss in grip strength.

In this scenario, the grip strength readings indicate a significant decrease when measured against the normal. The formula commonly used involves calculating the average of the grip strengths for both the injured and normal states, determining the percentage of loss. The result shows a specific degree of permanent disability expressed in percentage terms.

The option of 13% reflects a calculated disability rating that aligns with standard assessment protocols for grip strength loss in relation to functional expected outcome after such an injury. This rating takes into consideration the impairment attributed to the fracture and implicates how much the injury has impacted the individual's ability to perform work-related tasks, which for a baker, is heavily reliant on hand function.

This level of disability percentage provides an appropriate reflection of the limitations faced by the baker as a direct outcome of the injury.
