RV Evans Company Distributors (hereinafter referred to as "employer") hired the claimant, Mr. Joseph Harper, in the latter months of 2000. Mr. Harper was a delivery driver, and would bring boxed nails to construction sites. Claimant would carry boxes of nails weighing anywhere from 35 to 50 pounds each, and would deliver as many as 6 pallets of nails a day, 100 boxes of nails to a pallet. Mr. Harper testified that on either June $4^{\text {th }} or 6^{\text {th }}$ of 2003 , while in the process of stepping down out of his truck carrying a fifty pound box of nails at his side, he suffered a "pop" in his back. Mr. Harper recalls that he continued to work that day, and that he did not seek medical attention that evening, but believes that he advised Eric Frahm, his supervisor, that same day as to his back complaints. Mr. Harper alleges that his employer made a phone call to another office in Decatur, Illinois, and that as a consequence of that phone call claimant was advised
that the employer did not have a "company doctor" in the St. Louis area, and that claimant should go to his own physician until such time as the injury was determined to be work related.
Mr. Harper acknowledges that after the event described in June of 2003, he first sought medical attention from Dr. Thomas Lee on 6/30/03. Claimant acknowledged at hearing that he had seen Dr. Lee on a prior occasion, in September of 2002, for evaluation of back complaints after jumping out of his truck in early July of 2002. The testimony of Mr. Harper, to the extent that he was treated very briefly in September of 2002 for a back strain that resolved without further complaint, is consistent with the records of Dr. Lee. Those records fail to document any follow up evaluations by Dr. Lee after the injury was diagnosed on 9/04/02 as a lumbosacral sprain, until such time as Dr. Lee met with Mr. Harper again on 6/30/03 (See Claimant's Exhibit A1).
The records of Dr. Lee indicate that in June of 2003 Mr. Harper was complaining of "back pain symptoms corresponding to the right L5 radiculopathy". MRI was ordered to rule out possible right L4-5 herniation. MRI from
South County Open MRI was interpreted as showing degenerative discs at certain levels, with right facet hypertrophy and disc protrusion. The interpreter of the MRI noted "the protrusion does significantly affect the canal, S1, and possibly the L5 right roots".
Dr. Lee prescribed physical therapy and epidural steroid injections for "persistent symptoms related to right leg radiculopathy". The records of Dr. Graham document a history of having provided claimant with epidural steroid injection to the low back on 7/8/03 and again on 7/16/03 (See Claimant's Exhibit B-1).
While it is true that the treatment records of Dr. Lee for June and July of 2003 fail to document any history as to contemporaneous work injury, the hand written notes of Dr. Graham dated 7/8/03 (Exhibit B1) provide, in part, as follows with respect to complaints as to the right lower extremity: "Started in (sp?) 7/03, without event. Was working delivering nails."
Claimant continued to have complaints, and continued treating with Dr. Lee for back and right lower extremity symptoms. Claimant had ongoing physical therapy and was prescribed pain medication; on 11/17/03 Dr. Lee noted that claimant was having no improvement with physical therapy, and chose to order a lumbar myelogram. On 11/26/03, the date the myelogram was performed, Mr. Harper also had an examination performed by Dr. Barry I Feinberg. Dr. Feinberg performed his evaluation without the benefit of the CT myelogram, and concluded that the claimant would benefit from physical therapy for an apparent right L5 radiculopathy.
On 12/1/03 Dr. Lee met with the claimant after having the CT myelogram results, and interpreted the myelogram and post myelogram CT taken on 11/26/03 as showing an L5 herniation that would account for the claimant's complaints. Dr. Lee then discussed a surgical option with Mr. Harper, and as to possible fusion.
Claimant testified that after his injury in June of 2003 he continued to perform his delivery job, but notes that the employer accommodated his complaints by arranging for contractors to come to the curb for delivery of the nails, as opposed to having Mr. Harper carry the nails to the construction trailers. Mr. Harper did not seek further medical treatment for his complaints prior to leaving his employment in late January of 2004. Mr. Harper testified that delivery of nails became impossible due to his ongoing back and leg complaints.
Mr. Harper notes that in short order he went through a warehouse job, a carpenter job, and a painting job, before finding employment with Innsbruck Resort on 5/8/04. Claimant notes that his primary function is to go through a "punch list" with owners of new home construction, and to make the necessary corrections or minor repairs as listed on the punch list. The surveillance videotapes in evidence show Mr. Harper at work on 11/28/05, performing his usual duties for Innsbruck. Mr. Harper was observed carrying items from his truck, including a 20 gallon bucket filled perhaps as much as six inches deep with drywall mud for drywall repair. Claimant was also observed carrying large boxes believed to contain screens or screen frames for doors; a six-foot ladder; and, with the assistance of another worker, a cabinet believed by Mr. Harper to be made of particleboard, weighing about 20 pounds. Claimant testified that his employer was aware of his back complaints, and did not require claimant to perform any significant lifting.
Mr. Harper acknowledges that he continued working, and did not seek further medical care until returning to see Dr. Feinberg for a second evaluation in April of 2005. It is not at all clear that Dr. Feinberg had the benefit of the CT myelogram taken in November of 2003, inasmuch as he references the MRI but makes no comment as to the CT myelogram findings. Dr. Feinberg performed a physical examination and recommended a pain management program for what he describes as "a lumbar radiculopathy, primarily at the right L5 level", with other findings as to mechanical dysfunction of the lower back, and as to changes at the thoracic spine with occipital headaches developing (See Exhibit D1).
The employer and insurer then referred claimant to Dr. David R. Lange for an independent medical evaluation as to the spine. On 7/07/05 Dr. Lange had the opportunity to elicit a history from Mr. Harper; to review the medical records, including as to the lumbar myelogram and post myelogram CT; and to perform a physical examination. Dr. Lange believed the claimant to present with a lumbar radiculopathy, and noted that a simple discectomy alone would not be sufficient to treat ongoing leg and back pain See Exhibit C1).
On August 29, 2005 Dr. Lange performed a follow up examination, documented ongoing back and right lower extremity symptoms, and recommended a repeat MRI. By history provided by Dr. Lange (there is no 9/15/05 MRI report in evidence) the claimant had a repeat MRI, and that MRI showed, among others, a degenerative disc disease at L5-S1 with narrowing of the right L5 nerve canal due to an arthritic joint, and "a disc prominence, probably consistent with a contained herniation in the mid zone".
Dr. Lange recommended the lumbar discography performed at DePaul Health Center on 10/11/05. Dr. Robert J. Gresick Jr. performed the discography and recorded his conclusions (Report contained within Exhibit C-1). After having reviewed the report with Dr. Gresick, Dr. Lange concluded that he would be unable to "enthusiastically" offer surgery to Mr. Harper. Dr. Lange also did not believe that chronic pain management was warranted.
By deposition, Dr. Lange explained that he had a couple of reasons for being opposed to offering surgery. For one, he noted that the discography at L2-3 level showed reproduction of claimant's usual back pain, and Dr. Lange was loathe to offer a decompression and surgery at noncontiguous levels at L2-3 and L5-S1. Secondly, Dr. Lange noted that while the discography at L5-S1 level reproduced back pain, it failed to reproduce pain in the right leg, making it difficult for him to recommend surgery at a level that didn't reproduce symptoms (Joint Exhibit I, at pp. 2022).
Dr. David G. Kennedy met with Mr. Harper on 11/15/05, took a history, reviewed the various medical records, and performed a physical examination. Dr. Kennedy concluded that claimant exhibited pain radiating in to the right leg "in a clearly sciatic distribution". He also interpreted the 9/15/05 MRI as demonstrating a 6 mm disc prolapse at L5-S1 with foraminal encroachment on the right side (See Exhibit E-1). Dr. Kennedy agrees with Dr. Lange to the extent that both surgeons believe that a microdiscectomy alone would not offer sufficient long-term pain relief. Given a history of intractable sciatic pain dating back to the date of the alleged injury, Dr. Kennedy disagrees with the conclusion of Dr. Lange as to a surgical option. Dr. Kennedy believes that a history of intractable pain makes claimant a surgical candidate. Dr. Kennedy also recommended a follow up myelogram "to assess the bony detail and the facets at L5-S1."
