The issues to be determined by this hearing are as follows:
1) whether the medical treatment of the low back received after August 5, 2002 was causally related to the December 10, 2001 date of injury;
2) whether the Employer is liable to Claimant for past medical expenses of $\ 39,377.88;
3) whether the Employer is liable to Claimant for future medical care; and
4) whether the Claimant sustained any injury and, if so, the nature and extent of that injury.
The parties agree that Claimant sustained injury to his low back on December 10, 2001 that occurred within the course and scope of his employment. However, the parties disagree that Claimant's physical symptoms of his low back after Dr. Ebelke found him at maximum medical improvement on August 5, 2002 are causally related to the work injury of December 10, 2001. The parties also dispute whether the medical treatment, including a fusion performed by Dr. MacMillan after August 5, 2002, was causally related to the December 10, 2001 injury.
Claimant began employment with Wire Rope in 1971. He worked performing various job duties that required heavy repetitive activity. Claimant did not have any back problems that were hindrances or obstacles to his employment prior to December 10, 2001.
On December 10, 2001, Claimant felt a sharp pain of his low back when attempting to move a 1,000-pound spool. The Employer immediately sent him for treatment. An MRI taken revealed degenerative disk disease at L5-S1 and a herniated disk at L3-4. Dr. Ebelke recommended a series of epidural injections. Thereafter, on March 29, 2002, Dr. Ebelke recommended surgery at the L5-S1 and L3-4 levels.
The Employer then sent Claimant to Dr. MacMillan who opined Claimant was a candidate for lumbar fusion. Dr. Ebelke advised against the fusion procedure and released Claimant at maximum medical improvement on August 5, 2002. However, Dr. Ebelke also noted, "I have no objections to him returning to see Dr. MacMillan if he still wishes to pursue the possibility of surgery." (See Dr. Ebelke's report of August 5, 2002.)
Claimant continued to work at Wire Rope after August 5, 2002. Claimant on many occasions requested additional treatment of his low back but was denied by his Employer. Claimant then sustained bilateral shoulder injuries that required surgical intervention. Claimant reached maximum medical improvement of his left shoulder on July 17, 2003 and reached maximum medical improvement of his right shoulder in June of 2004. Despite receiving treatment on his shoulders, Claimant, through his attorney, continued to demand medical care of his low back based on Dr. MacMillan's recommendations. His Employer denied the request.
In September of 2004, Claimant was involved in a motor vehicle accident. Claimant sustained injury to his neck and his left upper extremity. Claimant received treatment of those areas and eventually the neck and left upper extremity resolved. Claimant testified the pain of his low back remained the same as it did prior to the motor vehicle accident.
Thereafter, Claimant sought treatment of his low back on his own. He received epidural injections by a Dr. Aks in November 2004 without relief. On June 3, 2005, Claimant went to Dr. MacMillan, who performed a fusion as recommended in April of 2002.
Several doctors' opinion were admitted into evidence regarding medical causation of Claimant's low back condition a
