Karen Larson was employed by the Missouri Chamber of Commerce and Industry (Chamber) from January through June of 2007. Ms. Larson was hired as an executive assistant to Daniel Meehan, the Chamber president. During the last week of March 2007, Ms. Larson was assigned to work at the Capitol, where she would obtain amendments to bills from the copy room and then walk to a scanner where she would scan and transmit the amendments back to the offices of the Chamber. The distance from the copy room to the scanner varied, depending on the location of the scanner, but appears to have been no more than 145 feet at any time. Although Ms. Larson

did not initially have a chair to sit in while she was stationary, after a few weeks of work at the Capitol, a chair was always available for Ms. Larson's use. Ms. Larson appears to have been at the Capitol for no more than 17.5 hours a week during the eight weeks that she was assigned to work there, sometimes working as little as four or five hours a week at the Capitol. The number of amendments handled varied from three to 40 per week, depending on the weeks and hours worked, as well as whether there was assistance from other Chamber employees.
Ms. Larson claimed that she dressed in a more business-like fashion, wearing two to two-and-one-half inch high heels when she worked in the Capitol, and that walking on the marble floors caused her to have arthritis in her left big toe, a condition called hallux limitus. There is some question regarding the requirement of wearing high heels for her work in the Capitol, as there is with regard to whether Ms. Larson actually wore heels for all of her work in the Capitol.
Ms. Larson initially complained of pain in her left big toe in April of 2007, and went to a podiatrist, Dr. Carron, on May 14, 2007. Dr. Carron initially treated Ms. Larson conservatively with a steroid shot and a flat shoe for the left foot, but operated on Ms. Larson's left big toe in November of 2007.
Dr. Carron, DPM, testified by deposition with regard to his treatment of Ms. Larson's left great toe. Dr. Carron diagnosed Ms. Larson with an arthritic condition or hallux limitus of the left great toe. Dr. Carron stated that hallux limitus is an arthritic condition of the joint that limits Ms. Larson's ability to move the joint and causes pain as she walks and tries to move the joint. Dr. Carron stated that wearing a high heel will aggravate the condition of hallux limitus and possibly precipitate symptoms "because you're forcing the foot into a position where you're - by lifting the heel, you're putting stress and dorsiflexion on the joint to the point where it can cause the spurring, if there's spurring there, to jam into the joint with more force and more pressure and become more symptomatic. So I would say that there is a correlation to wearing a high-heeled shoe aggravating the symptomatology..." When directly asked about whether the high-heeled shoes caused the hallux limitus, Dr. Carron responded that "there may be some underlying factors there, but by placing the foot in what I would consider an unnatural position in a high heel would cause the stresses that would develop the spurring and the inflammation of the joint." Dr. Carron acknowledged that the visible spurring that Ms. Larson had in the x-ray of her left big toe in May of 2007 would have taken "months to years" to develop. With regard to the surface walked on, Dr. Carron stated that the softer the surface walked on "should correlate into less pain."
Dr. Craig Aubuchon, MD, testified by deposition that he evaluated Ms. Larson's left great toe and also diagnosed hallux limitus of the left great toe. Dr. Aubuchon described hallux limitus as arthritis of the big toe and limited motion. Dr. Aubuchon stated that "high heels certainly will cause more symptoms because if one has limited motion of the big toe and you raise your heel which requires you to bring your toes up that is painful to people with arthritis of their big toe. The big toe then hits that - that spur on the top of the first metatarsal head and causes pain. It stretches things. So someone with arthritis of the big toe is more painful in high heels because of a necessity to bring the big toe up." Dr. Aubuchon stated that the surface walked on was not a big factor in aggravation of hallux limitus, rather that it was the position of the toe in pushing up and hitting the spur that caused the pain. Dr. Aubuchon opined that Ms. Larson's left great toe complaints were not work related, saying that "the fact that shortly after she developed
symptoms she sought ... medical treatment and at that time the X-rays revealed this hallux rigidus with marked narrowing of the joint and a spur formation. So something like that to form had to take years to form. It wasn't -it didn't develop over weeks or even months. So that was a preexisting condition." Dr. Aubuchon stated that hallux limitus and hallux rigidus are interchangeable terms designating arthritis of the big toe. During cross-examination, Dr. Aubuchon again reiterated that the degenerative changes in Ms. Larson's left great toe would have taken years to develop.
