Based on the above exhibits and the testimony presented at the hearing, I make the following findings:
- The claimant is a 55 -year-old woman who is left hand dominant.
- The claimant has worked for the employer as a registered nurse for the past 14 years. She performs her job on a full-time basis, with some overtime work.
- While working with her hands, the claimant performs activities such as pulling and pushing files in a file cabinet, manually pumping blood pressure cuffs, pushing carts of laundry, lifting bags of laundry, keyboarding, giving injections, and performing ear lavage.
- The claimant developed symptoms in her hands, in the form of numbness and tingling that would wake her at night. She sought medical care from her employer, Patients First Health Care. On November 6, 2006, Dr. Kenneth Smith at Patients First noted that the claimant had bilateral carpal tunnel syndrome. He indicated that he would check nerve conduction studies and EMGs, and that the claimant might be a candidate for surgery in the future. Dr. Smith told her that she could continue her nocturnal wrist splinting. On November 15, 2006, the notes from the EMG and NCV studies revealed mild bilateral carpal tunnel syndrome affecting sensory and motor components.
- The claimant saw Dr. Benjamin Verdine on November 28, 2006. Dr. Verdine noted that the claimant has carpal tunnel syndrome, left greater than right. He gave her an injection. His notes indicate that they discussed her options, including continued splinting or surgical intervention.
- Dr. Verdine performed surgery on each of the claimant's wrists in March 2007. The left wrist was operated on first, with an open carpal tunnel release being performed on March 2, 2007. Surgery was performed on the right wrist about two weeks later, on March 16, 2007. The claimant was off work for four weeks due to her wrist surgeries. She was compensated for this time off by the employer/insurer.
- After the surgeries, the claimant received physical therapy through Washington Physical Therapy. The claimant began physical therapy around March 22, 2007, and completed the therapy on April 16, 2007. At discharge, the therapist noted that the claimant made good progress, although she complained of some weakness.
- The claimant saw Dr. Verdine for follow-up visits on March 28, 2007 and on April 18, 2007. He released her to work full duty effective April 23, 2007. At the May 14, 2007 visit, the doctor noted that the claimant had reached maximum medical improvement. He also wrote that he believed that the claimant will have no permanent partial disability related to the injury, and that he did not believe that she will require any additional treatment.
- The claimant again saw Dr. Verdine on October 17, 2007. Dr. Verdine reported that "her biggest complaint now is of some fatigability of her forearm." Dr. Verdine reported that the fatigability occurs when the claimant carries several heavy charts at a time or when she does a lot of repetitive activities. The doctor noted that the claimant's sensation was normal, as was her range of motion. He did not feel any CMC arthritis. Dr. Verdine thought that the claimant's current symptoms were not related to her carpal tunnel release, but he was unsure of the pain's "exact etiology."
- An undated medical record from Patients First Health indicates that the claimant's next appointment was on March 28, 2007, and that her bilateral carpal tunnel syndrome is work-related. A similar form, showing the next appointment as April 18, 2007, also indicates that the diagnosis is bilateral carpal tunnel syndrome and that the condition is work related. The same form, dated April 18, 2007, again reflects the same diagnosis and that the condition is work-related. Another copy of the form, dated May 14, 2007, gives a diagnosis of bilateral carpal tunnel syndrome, and notes that the condition is work related.
- Dr. Mark Lichtenfeld examined the claimant on May 29, 2008. In his report, he noted that the claimant has the following diagnoses: 1) bilateral carpal tunnel syndrome; 2) status-post bilateral carpal tunnel release; and 3) residual symptoms from her bilateral carpal tunnel syndrome. He also indicated that the substantial cause of the claimant's bilateral carpal tunnel syndrome was the cumulative trauma work she did for her employer. He rated the claimant's permanent partial disability at 30 % of her left wrist and 27.5 % of her right wrist, and he added a loading factor of 15 %. He opined that she is in need of further treatment as a result of her bilateral carpal tunnel syndrome in that she would benefit from treatment with anti-inflammatory medications to be taken on an asneeded basis. Due to her history of gastrointestinal symptoms, she should use caution in taking antiinflammatory medication on a regular basis. He indicated that she might be able to be treated with Celebrex for her ongoing wrist and hand symptoms. He also felt that she would benefit from work restrictions of avoiding repetitive and power gripping with her hands; avoiding using any type of gas, electric or air-powered tools with her hands; avoiding using torquing and impact tools; avoiding repetitive lifting of more than six to eight pounds with either hand; and avoiding working with her arms outstretched and overhead.
- Dr. Lichtenfeld's deposition was taken August 8, 2008. In addition to reiterating his findings noted above, he testified that claimant has continued irritation in her wrists, probably from scar tissue around the nerve, but possibly from epineural fibrosis. Dr. Lichtenfeld found that the claimant has lost motion in her wrists, which he attributes to scar tissue. The claimant has a decreased pinprick sensation in the median nerve distribution of her hands, which is a sign of ongoing damage to the median nerve. Dr. Lichtenfeld found that there was decreased circumference in the claimant's left forearm, her dominant arm, which is indicative of atrophy due to an avoidance of using her arm. Dr. Lichtenfeld also clarified that the claimant's work was the substantial and prevailing cause of her bilateral carpal tunnel syndrome.
- Dr. Lichtenfeld took issue with several things in Dr. Verdine's May 14, 2007 report. Dr. Lichtenfeld pointed out that although Dr. Verdine indicates that there was no limitation of the range of motion, the doctor does not provide "even one quantitative measurement in any of the six planes of movement. He fails to test any type of sensation, pinprick sensation. He doesn't mention the Tinel's sign, Phalen's sign or reverse Phalen's sign. There's no notation of any measurement of the forearm to ascertain if there's any atrophy." Although Dr. Verdine did not assess any permanent partial disability, Dr. Lichtenfeld points out that "it's hard to assess the permanent partial disability when a quantitative examination is not performed or noted in their examination."
- Dr. Verdine's deposition was taken on October 7, 2008. Dr. Verdine did not place any restrictions on the claimant when he discharged her, and he does not believe that she has any permanent disability. He acknowledged that the claimant returned to see him in October 2007 due to ongoing symptoms, particularly in the left forearm. He also admitted that he did not measure the circumference of her forearms. He erroneously testified that the claimant is right-handed. Dr. Verdine used the AMA (American Medical Association) guidelines when he evaluated the claimant's permanent partial disability. He testified that for carpal tunnel syndrome, the AMA guidelines look at the function of the nerves post-operatively.
- The claimant continues to have complaints in her hands and wrists. Her complaints include an occasional numbness with pain on pressure of the palms, along with pain in her hands and wrists. Her symptoms sometimes wake her at night, and they are made worse with activity. She has difficulty driving, pulling charts, performing ear lavage, opening jars, picking up coins, fishing, and similar activities. The claimant tends to drop things. She believes that her right hand is a bit better than her left hand. She treats her symptoms with ibuprofen.
- The claimant has never injured her hands or wrists in the past.
