The administrative law judge found that, as a result of the primary injury, employee sustained permanent partial disabilities of 271 / 2 % of the body as a whole due to his cervical spine injuries; 5 % of the body as a whole due to a concussion; and, 5 % of the right elbow. We affirm these findings.
The administrative law judge found that as of the date of the primary injury, employee suffered a pre-existing permanent partial disability of 171 / 2 % at the level of the left ankle. We affirm.
Dr. Lichtenfeld described the physical restrictions he would impose for each disability and opined that employee's disabilities constituted hindrances or obstacles to employment. Dr. Lichtenfeld also opined that the disabilities from the primary injury combined with the preexisting ankle disability to result in greater disability than the simple sum of the disabilities. We find credible these opinions of Dr. Lichtenfeld.
The administrative law judge found that a 10\% enhancement factor fairly represents the synergistic effect of the combination of the primary injury and the preexisting disabilities. We agree.
The administrative law judge included the following disabilities when calculating employee's overall disability.
27.5 % of the body as a whole ( 400 week), cervical spine $=$ 110.00 weeks
5 % of the body as a whole ( 400 week), concussion $=$ 20.00 weeks
5 % at the right elbow ( 210 week) $=$ 10.50 weeks
17.5 % of left ankle ( 155 week level) $= 27.12 weeks
Overall Disability =$ 167.62 weeks
The administrative law judge then applied the 10 % enhancement factor to the overall disability and awarded to employee 16.76 weeks of enhanced permanent partial disability from the Second Injury Fund.
