Dr. Jacques Van Ryn testified on behalf of employee by deposition on July 23, 2010. Dr. Van Ryn evaluated employee on June 10, 2010. Dr. Van Ryn reported reviewing the records regarding employee's treatment from 1996 to present. Dr. Van Ryn testified that employee's symptoms regarding his carpal tunnel syndrome began in
approximately 1999. Dr. Van Ryn did not ask employee if his symptoms in his body parts from his avascular necrosis had gotten better, worse, or stayed the same as they were in June 2001. However, Dr. Van Ryn testified that according to the records, his pain symptoms had gotten worse in the affected body parts. Dr. Van Ryn opined that the work employee performed while at employer is the "predominant prevailing factor and the causation of bilateral ulnar and carpal tunnel syndromes."
With regard to the primary injury, Dr. Van Ryn opined that employee is 15\% permanently partially impaired of both the right and left upper extremities rated at the wrists due to his carpal and ulnar tunnel syndromes. With regard to employee's preexisting conditions, Dr. Van Ryn opined that employee is 50\% permanently partially impaired of the upper left extremity rated at the shoulder, 20 % permanently partially impaired of the upper right extremity rated at the shoulder, 25 % permanently partially impaired of the lower left extremity rated at the hip, 10 % permanently partially impaired of the lower left extremity rated at the knee, and 5 % permanently partially impaired of the body as a whole due to his degenerative cervical disc disease. Dr. Van Ryn also noted that employee has significant medical disease including diabetes, sick sinus syndrome, and has a pacemaker; however, he did not assign a disability rating for these preexisting conditions.
Dr. Van Ryn concluded that "as a result of the bilateral carpal tunnel and ulnar tunnel syndromes combined with his extensive preexisting medical condition has caused [employee] to be unable to do any gainful employment. He cannot compete in the open labor market. Therefore[,] he is permanently completely disabled for work."
Ms. Delores Gonzalez, a vocational expert, testified by deposition on behalf of employee on July 26, 2010. Ms. Gonzalez evaluated employee on September 15, 2006 and November 24, 2006. Ms. Gonzalez opined that based on a combination of employee's physical ailments and conditions and his vocational background, he is unable to engage in substantial gainful activity.
Ms. Gonzalez testified that her opinion that employee is not employable is based in part on how he presented physically as of the date she saw him in 2006. Ms. Gonzalez did not ask employee if his preexisting conditions got better, worse, or stayed the same after the primary injury date of July 5, 2001.
