Stanley White ("Claimant") was born on February 7, 1952. Claimant began work for Employer in 1979, and has worked for Employer continuously since that time. From 1979 through 1993, Claimant's position was that of "pipefitter/welder"; that position required significant overhead work and hand-intensive work. As a pipefitter/welder, Claimant used jackhammers, welders, grinders and other vibrating tools. Since 1993 or 1994, Claimant's position has been "gas service worker". As a gas service worker, Claimant services both commercial and residential customers in a large geographic area. Claimant drives a heavy duty pickup truck furnished by Employer. Until 2001, the trucks had five-speed manual transmissions; since that time the trucks have had automatic transmissions.
On August 25, 2005, Claimant filed with the Missouri Division of Worker's Compensation his "Claim for Compensation" alleging a date of accident or occupational disease of August 16, 2005, and claiming injury to "(l)eft and right shoulders, arms, hands and wrists" and further stating: "(i)n the course and scope of employment, constant and repetitive use of his hands and arms has led to the development of injuries". The Claim for Compensation clearly posits a theory of occupational disease due to repetitive motion. The evidence presented at the hearing, as well as the post-hearing briefs, further define Claimant's alleged injuries due to the alleged occupational disease(s) to be right carpal tunnel syndrome, left carpal tunnel syndrome, and bilateral shoulder impingement syndrome and rotator cuff tendinitis. Employer has denied the allegations of the Claim for Compensation, and no medical benefits or other benefits have been provided under Chapter 287, RSMo.
In 1994, Claimant suffered a rotator cuff tear in his right shoulder for which he underwent surgery. About a year post-surgery, Claimant's right shoulder again became symptomatic with pain, weakness and soreness; injections in his shoulder provide only temporary relief.
In March 2002, Claimant was seen by Dr. Robert Orell for right hand and right shoulder complaints. Dr. Orell's initial diagnoses were right shoulder impingement syndrome and Raynaud's phenomenon of the right hand. Claimant's shoulder was injected on March 19, 2002; on May 17, 2002 Claimant told Dr. Orell that his shoulder was much better following the injection. Claimant did not see Dr. Orell again until January 15, 2004, when an additional injection was done of the right shoulder. Claimant then saw Dr. Orell again on April 19, 2004; on that visit Claimant stated that the injection improved his shoulder approximately 60 %. Also on that visit Dr. Orell noted that Claimant had a new complaint of left carpal tunnel syndrome which had been present for three years but had gotten worse over the past three months. On June 8, 2004, Claimant indicated to Dr. Orell that his left carpal tunnel symptoms were much better and that his right shoulder was better. Also on June 8, 2004 Dr. Orell noted that nerve conduction/EMG testing showed bilateral carpal tunnel syndrome, worse on the right. Claimant canceled his appointment with Dr. Orell on October 19, 2004, but returned to see Dr. Orell on March 22, 2005; Claimant's right shoulder was injected.
In April 2005, Claimant had an accident at home when a large engine struck his right hand. Claimant saw Dr. Orell on June 15, 2005 and Dr. Orell suspected tendon damage in the right hand as a result of the accident, and referred Claimant to Dr. Subbaro Polenini. Claimant underwent surgery with Dr. Polenini on August 17, 2005 to repair extensor tendon lacerations caused by the accident; a right carpal tunnel release and right trigger thumb release were also performed by Dr. Polenini at the same time. (Dr. Polenini performed additional surgery on the tendons on April 14, 2006.)
On September 20, 2005, Claimant again saw Dr. Orell, who injected Claimant's right shoulder again. Discussion was held concerning right shoulder surgery, left carpal tunnel release surgery and left index finger surgery; on that date Claimant wished to defer all surgeries.
On December 2, 2005, Claimant was seen by Dr. James Schaberg at Dr. Polenini's request for right shoulder pain. Another shoulder injection was done on that date. A rotator cuff tear was suspected, therefore a right shoulder MRI was performed on December 6, 2005 which showed no tearing but suggested impingement syndrome. Physical therapy was started.
Claimant was seen at the request of his attorney by Dr. Bruce Schlafly on February 12, 2008 for an evaluation. Dr. Schlafly opined in his report of that date that Claimant had developed work-related bilateral carpal tunnel syndrome, and that Claimant's repetitive work with his hands while working for Employer was the substantial and prevailing factor in the cause of the bilateral carpal tunnel syndrome. Dr. Schlafly recommended left carpal tunnel release and noted that Claimant had already undergone right carpal tunnel release. Dr. Schlafly also recommended that Claimant consider surgery on his right shoulder, and that "given the type of work that he has been performing over the years for Ameren UE, including carrying the heavy gas meters, it is probable that these work activities are the substantial and prevailing factor in the need for additional treatment of the right shoulder." There is no mention of the left shoulder in Dr. Schlafly's report of February 12, 2008.
At Employer's request, Claimant was seen by Dr. Mitchell Rotman. At the time of his initial evaluation on October 8, 2008, Dr. Rotman noted that Claimant had chronic problems with his right shoulder ever since his original injury in the mid-1990's. Dr. Rotman recommended an MRI scan be obtained of the left shoulder, although Dr. Rotman felt that the need for the MRI could not be clearly related to any type of work related injury. Dr. Rotman also believed that the need for any further treatment with respect to the right shoulder would be related to his incident back in the 1990's.
With respect to the bilateral carpal tunnel syndrome, Dr. Rotman stated that in his opinion, Claimant did not do a repetitive job in that his jobs are spaced apart with prolonged driving from one job to the other, although admittedly, his job requires heavy use of the hands and occasionally may have involved use of some power tools or hand tools. He noted that Claimant's job based on his description did not fit the criteria for a work related carpal tunnel syndrome.
Dr. Rotman evaluated Claimant again on November 21, 2011. Dr. Rotman believed that Claimant did not do repetitive overhead work and, therefore, he did not see any evidence of a work related injury to the left shoulder; Dr. Rotman believed that the left shoulder findings were simply age related. Dr. Rotman again noted that he did not see any evidence of a work related injury to Claimant's hands or shoulders. Dr. Rotman's deposition testimony was consistent with his narrative reports.
Claimant continued to treat with Dr. Schaberg periodically off and on through September 23, 2011, undergoing injections to both shoulders. An MRI of the left shoulder was also done on February 23, 2009, which revealed tendonopathy of the supraspinatus tendon and AC joint hypertrophic changes and mild bursitis of the deltoid bursa. Dr. Schaberg treated Claimant conservatively with injections and physical therapy, with the diagnosis being impingement syndrome. Dr. Schaberg's records do not contain any mention of causation with respect to Claimant's bilateral shoulder conditions.
Dr. Bruce Schlafly evaluated Claimant again on July 9, 2013. Dr. Schlafly's diagnoses were rotator cuff tendinitis and impingement of both shoulders and bilateral carpal tunnel syndrome. In Dr. Schlafly's opinion, Claimant's repetitive and forceful physical labor duties performed by him in the course of his employment as a gas service man were the substantial and prevailing factor in the cause of his bilateral carpal tunnel syndrome and bilateral shoulder impingement and rotator cuff tendonitis and the need for treatment. Dr. Schlafly recommends a left carpal tunnel release as well as bilateral shoulder arthroscopies as recommended by Dr. Rotman. Dr. Schlafly noted that if Claimant was not able to obtain additional treatment, then he has a 35 % permanent partial disability of the left hand due to the left carpal tunnel syndrome and 45 % of the left shoulder due to impingement syndrome and rotator cuff tendonitis. Dr. Schlafly also reiterated his prior ratings of 25 % permanent partial disability of the right hand and 45 % permanent partial disability of the right shoulder.
The testimony of Claimant and the testimony of his supervisor, Donald Schaper, were quite consistent regarding Claimant's duties as a gas service worker. Schaper testified that the job requires lots of overtime and long hours. Schaper testified that Claimant's work is hand intensive with the use of tools and that approximately $1 / 4$ of Claimant's work day consists of the
use of hand intensive tools. Schaper also agreed that Claimant's work requires approximately 2 hours of computer keyboard work per day.
