Claimant is a fifty-five year old man who earned his GED while in the military. He worked for Employer from February 1996 to September 2008. In 2003, Claimant was working full-time as a yard worker. His duties included driving vehicles off an assembly line onto a parking lot.
On Friday, June 20, 2003, while talking on a cell phone with his wife and getting out of a panel van, a co-employee slammed the van door, striking his head and knocking him back inside the van. He experienced "serious headache and neck pain," and later reported seeing stars, but initially declined Employer's offer of medical care. Over the weekend, he experienced headaches, nausea and loss of focus. He could not recall the name of his daughter's boyfriend. Upon his return to work Monday morning, Claimant requested treatment.
In response to Claimant's request for treatment, Employer referred him to Barnes Care in Fenton, Missouri on June 24, 2003 where his chief complaint was pain in his neck and headaches. Barnes Care records indicates "no numbness or loss of feeling in arms or hands...had no LOC...says he was dazed after injury...no visual problems...no dizziness." The medical history taken at that time indicated no prior headaches or neck problems.
X-rays taken at BarnesCare on June 24, 2003 indicated a normal skull and degenerative spondylosis along the anterior inferior end plate of C5 and C6 with adjacent intervertebral disc space narrowing at C6-7 and very minimal narrowing at C5. The diagnosis at that time was strained neck and mild frotal head contusion. BarnesCare released Claimant to return to work without restrictions, and discharged him from care on June 25, 2003.
Claimant saw his personal physician, Dr. Tim E. Baker, on June 26, 2003 complaining of "headaches and dizziness.....some short term memory loss." Dr. Baker's physical exam reflected "some memory loss...some cognitive impairment," and his diagnosis was a closed head injury. He took Claimant off work. Washington Medical Group charged $\ 57.00 for the June 26, 2003 date of service. An MRI of the head taken at St. John's Mercy Hospital on June 27, 2003 revealed findings consistent with a small venous angioma within the right cerebellar hemisphere, and an otherwise normal study. The charges from St. John's for the MRI were $\ 1,189.75, with an additional charge of $\ 284.00 from West County Radiological Group ( $\ 1,473.75 total charges for June $27^{\text {th }}$ date of service).
On June 27, 2003, Counsel for Claimant demanded additional treatment and TTD, and warned the insurance adjuster that there was "reason to believe that [Claimant] may have suffered a brain contusion." The reply from Employer's counsel, thirteen days later, was a complete denial of the additional medical treatment and TTD.
At his next visit on July 8, 2003, Claimant's complaints included continuing headaches; dizziness, ear ringing, memory loss and trouble hearing. ${ }^{1}$
On July 22, 2003, Claimant reported to Dr. Baker that he was feeling better and wanted to go back to work. Dr. Baker authorized Claimant to return to work, and BarnesCare approved Claimant to work, which he did on July 23, 2003. Washington Medical Group charged $\ 42.00 for the July 22, 2003 date of service. Claimant returned to work performing his normal duties.

[^0]: ${ }^{1}$ According to Exhibit 10, A Notice of Lien from Claimant's Insurance Fund, Dr. Albert Marchiando generated charges of $\ 190.00 on July 18, 2003. Presumably, Dr. Marchiando evaluated some diagnostic tests associated with Claimant's work injury, bty because De. Marchiando's records are not in evidence, there is no basis on which to award the charges incurred.
Beginning sometime in early 2004, Claimant began to experience an increase in the frequency of his headaches, and when he complained, Dr. Baker referred Claimant to Dr. Peebles, a neurosurgeon. On May 10, 2004, Dr. Peebles took a history, performed an exam, and issued a report. Dr. Peebles concluded that Claimant had chronic headaches "which were likely at least in part due to a post concussive etiology." He noted the increasing symptoms over time were atypical and additional diagnostic testing was unnecessary, but suggested several options for management of the pain with prescription drug therapy. The charge for Dr. Peebles' exam was $\ 250.00.
Claimant did not receive any relevant medical treatment until January 27, 2006, when he complained to Dr. Baker of severe headaches for a couple of weeks. Dr. Baker diagnosed "recurrent" headaches and prescribed medication. The charges with this visit were $\ 57.00.
On March 28, 2006, Dr. Shawn Berkin performed an Independent Medical Examination ("IME"). He took a history, conducted an exam, and issued a report. Claimant complained of violent headaches every other day, migraines with blurred vision, photosensitivity and nausea, and $4 / 10$ neck pain with stiffness. The final impression was: 1) Closed head injury; 2) Postconcussion cephalgia; and 3) Cervical strain. The work accident was the prevailing factor in causing these diagnose. He felt the resulting disability totaled 20\% PPD of the body as a whole. Dr. Berkin opined that Claimant's status would not significantly improve from further medical or surgical treatment, although he did recommend conservative measures to help Claimant deal with his ongoing symptoms. Dr. Berkin's deposition was not submitted into evidence.
On May 19, 2006, Claimant presented to Dr. Anthony Guarino for treatment of his neck pain. On exam, Dr. Guarino found no spasm, trigger points or tenderness. He diagnosed cervical radiculitis and spondylsis. He found Claimant had a degenerative process in his neck with symptoms that appear to be coming from the aggravation of C7 bilaterally, and began a series of nerve root injections. Claimant did not get lasting relief.
Claimant consulted neurosurgeon Todd Stewart on or about August 24, 2006. The record of the initial office visit is absent from the Trial Record, specifically Exhibit L, which purports to be the records and billing of Dr. Todd J. Stewart, M.D., and is not fully certified. Claimant submitted to surgery on September 12, 2006, and in the "Indications for Procedure" section of the operative report, Dr. Stewart noted a two-year history of neck pain, which was "worse over the past five months." Dr. Stewart diagnosed right C7 radicuopathy, removed disc osteophyte complex at C6-7 and fused Claimant's neck (C6-7 ACDF). Claimant reported marked improvement in his symptoms.
Two doctors testified by deposition regarding their IME's and the opinions formed therein. Dr. Robert Margolis, testifying for Claimant, gave his expert opinion that the incident of June 20, 2003 was the substantial and prevailing factor in accelerating Claimant's cervical spine degenerative disease leading to the surgery performed by Dr. Stewart. Dr. Margolis assessed Claimant's PPD at 35 % of the person as a whole. He further stated that Claimant's persistent unresolved headaches and memory problems, in which the work incident was a substantial factor, lead him to believe that additional evaluation and treatment if indicated was warranted. He felt that Claimant has still not reached maximum medical improvement for headaches and memory problems.
Dr. Daniel Kitchens evaluated Claimant on behalf of Employer. Dr. Kitchens has been a neurosurgeon since 1994. He performs cervical surgery and provides treatment for cervical spondylosis. Dr. Kitchens' diagnosis for the work injury was a mild concussion. Claimant should have reached maximum medical improvement approximately one month after the work accident. Dr. Kitchens testified that Claimant's work accident was not a substantial factor in the need for medical treatment from July 2003 to the present time.
Dr. Kitchens testified about Claimant's cervical spondylosis. He compared the radiographic studies from 2003 and 2006 that showed there was a worsening of Claimant's cervical spondylosis. This worsening of the cervical spondylosis would have been a natural event and would have occurred without trauma.
