Based on the testimony of Doris Dobbs ("employee") and the medical records and reports admitted, I find as follows:
At the time of the hearing, the employee was 49 years old and had worked for Jefferson Memorial Hospital ("employer") for the past 20 years. According to her testimony, the employee first sought treatment for her wrists in 1997 with Dr. Sides who prescribed her splints. Additionally, she had nerve conduction studies from Dr. Keely on September 29, 1997 (Employer-Insurer Exhibit 1, Deposition Exhibit 2, Page 2). At that time, the employee was working as a physical therapy rehab technician/aide where she was required to repetitively use her upper extremities to move patients, utilize gate belts, push wheelchairs, and lift patients (Employee Exhibit H)(Employer-Insurer Exhibit 2). The employee continued to work for the employer for the next several years without missing work for her wrists' condition. The employee began working in the employer's histology lab in 2000. While in the histology lab, the employee was required to work with a microtone where she would roll a knob 50,000 to 60,000 times in a three hour period every day. For the rest of the day, the employee would pick up specimens, take requisitions, keep up stock, and do computer work. All of her duties at the histology lab required constant use of her upper extremities. Since she continued to have problems with her wrists, the employee sought additional treatment for her wrists on August 17, 2000. At that time, the employee complained of pain in her left wrist and pain in her right shoulder with occasional numbness in hands that comes and goes. Dr. Sides diagnosed her with right proximal biceps tendinitis and left wrist tendonitis (Employee Exhibit B, Page 3). The employee went through some physical therapy, and Dr. Sides noted that the left wrist strain was resolved by September 14, 2000 (Employee Exhibit A1, Pages 65-71)(Employee Exhibit B, Page 4).
The employee next sought treatment for her wrists with Dr. Dwayne Helton on October 10, 2003. At that time, Dr. Helton diagnosed the employee with carpal tunnel syndrome and planned to order bilateral upper extremity nerve conduction velocity studies (Employee Exhibit C, Pages 2-3). Dr. John McGarry performed the nerve conduction studies on November 4, 2003 and noted abnormal nerve conduction study with definite evidence for median nerve entrapment on each wrist with a greater abnormality on the right than the left (Employee Exhibit D, Page 10). On December 22, 2003, Dr. Helton diagnosed the employee with moderately severe bilateral carpal tunnel and planned to refer the employee out for a surgery consult since she has failed wrist splints (Employee Exhibit C, Page 4). While getting treatment from Dr. Jeffrey Draves, the employee complained of carpal tunnel in both arms on March 17, 2004. The
employee continued to work for the employer and did not miss any work due to her bilateral carpal tunnel syndrome. On January 27, 2005, the employee filed her claim for compensation against the employer.
Dr. John McGarry did a second nerve conduction study on August 30, 2005 that supported his previous diagnosis of median nerve entrapment at the wrist on the right more than left (Employee Exhibit D, Pages 4-7). On October 13, 2005, Dr. Craig Ruble reviewed Dr. McGarry's nerve conduction studies and noted that the employee complained of bilateral hand numbness, tingling and pain that she could not relate to anything other than activity at work. Dr. Ruble provided the employee with splints and anti-inflammatory medication with a discussion of the risks of surgery. On October 20, 2005, Dr. Ruble performed a right carpal tunnel release on the employee. He performed the left carpal tunnel release on November 10, 2005. After releasing her back to work on December 5, 2005, Dr. Ruble noted on December 20, 2005 that the employee complained of a little weakness with her grip strength, occasional tingling and a little bit of soreness over the incision but stated that her releases were doing well. As a result, Dr. Ruble released her from his care to return on an as needed basis (Employee Exhibit F).
On March 30, 2006, the employee saw Dr. Robert Margolis for an evaluation. Dr. Margolis issued his report on April 24, 2006 and gave his deposition on November 20, 2007. Following his evaluation of the employee and a review of her medical records, Dr. Margolis noted that the employee first developed upper extremity symptoms while working in the physical therapy department but further continued while she was a histology technician. Further, he diagnosed the employee with bilateral symptomatic carpal tunnel syndrome and opined that her employment at Jefferson Memorial Hospital is the substantial prevailing factor in causing her bilateral carpal tunnel syndrome. In addition to noting that there is a synergistic effect between both wrists, Dr. Margolis opined that the employee suffered a permanent partial disability of 30 percent of each upper extremity at the level of the wrist (Employee Exhibit G).
On September 5, 2006, Dr. R. Evan Crandall evaluated the employee and later gave his deposition on January 8, 2008. At the time of her initial appointment, the employee filled out a questionnaire where she was asked about what part of her job that she thought caused your problem. As a result, the employee provided a detailed description of her job as a physical therapy technician and noted that her hands hurt so much she had to find another job and that is when she went to the lab. At the time of the hearing, the employee testified that she thought Dr. Crandall wanted her thoughts of the original cause of her bilateral carpal tunnel. Af
