On the evening of June 19, 2002, employee was examined at St. Joseph's Health Center. He complained of right-sided neck, shoulder, and hip pain, and numbness and tingling into the right leg. He was diagnosed with a contusion of the right hip and shoulder and a neck strain. He received an injection of Toradol and was prescribed Vioxx and Flexeril and advised to follow up with "work comp" in 2 to 3 days. (Claimant's Exhibit U, Pages 5-7)
Dr. Timothy Soncasie at Unity Corporate Health examined claimant on June 21. Mr. Hampson reported right shoulder, hip and lower back pain and headaches. X-rays taken of the right shoulder and low back were negative for fracture. Dr. Soncasie diagnosed claimant with a right shoulder/neck strain and a lumbar strain. Employee was told to continue taking Vioxx and Flexeril and was prescribed Vicodin and advised to start gentle stretching. (Claimant's Exhibit W, Pages 65-68) Dr. Soncasie reexamined claimant on June 25. He reported right shoulder, hip, and lower back pain and tingling in the fingers of the right hand. Dr. Soncasie diagnosed claimant with a right shoulder strain and a lumbar strain and told him to take Naprosyn when he finished the Vioxx. (Claimant's Exhibit W, Pages 70-72) He prescribed physical therapy for claimant's low back and right shoulder strains. (Claimant's Exhibit X, Page 199)
Mr. Hampson was evaluated by a therapist at St. Charles Sports and Physical Therapy on July 3. He reported pain in his right upper trapezius, shoulder, hip and low back. Claimant attended 6 sessions of physical therapy through July 15. He progressed slowly with cervical range of motion and continued to have mild to moderate pain with activities of daily living and shoulder retraction. (Claimant's Exhibit X, Pages 190-192 \& 200-203) Dr. Soncasie reexamined employee on July 16. Mr. Hampson reported right shoulder pain and right hip pain and popping. Dr. Soncasie referred employee to an orthopedic surgeon. (Claimant's Exhibit W, Pages 73-75)
Dr. James E. Walentynowicz at Chesterfield Orthopedics examined claimant on June 24, 2002. Mr. Hampson complained of lower back and right hip pain. On examination employee had some spasm in the right trapezius and tenderness in the low back, soreness in the region of his neck and right shoulder, and tenderness without spasm in the lower lumbar spine region. (Claimant's Exhibit FF, Page 3).Dr. Walentynowicz diagnosed employee with cervical, right trapezius, and lumbar strains and prescribed additional physical therapy for claimant's back, neck and right shoulder. (Claimant's Exhibit X, Page 198)
Mr. Hampson resumed physical therapy at St. Charles Sports and Physical Therapy on July 31. He attended 2 sessions of physical therapy through August 6, 2002. (Claimant's Exhibit X, Pages 193-94 \& 203-04) Dr. Walentynowicz reexamined claimant on August 6, 2002. Employee reported that his neck and back pain was improving. He walked stiffly. Dr. Walentynowicz prescribed additional physical therapy. Claimant had apparently undergone a whole body scan which Dr. Walentynowicz felt was normal. (Claimant's Exhibit FF, Page 573)
Mr. Hampson attended 10 additional sessions physical therapy through August 28. The therapist noted that
employee had achieved pain free full cervical range of motion with only infrequent episodes of right shoulder pain during movement and overhead activity. However, he continued to experience increasing warmth and numbness into both hip joints and the lumbar spine. (Claimant's Exhibit X, Pages 195-96 \& 204-210)
Dr. Walentynowicz examined claimant again on August 28, 2002. Employee complained primarily of back pain with radiation into both legs with occasional numbness. He had some soreness in his right shoulder. His cervical range of motion was normal. He ordered an MRI of the lumbar spine. (Claimant's Exhibit FF, Pages 3-4) It was performed on September 9, 2002.
Mr. Hampson attended 3 additional physical therapy sessions through September 10, 2002. The therapist noted that employee had achieved pain free full cervical range of motion with only infrequent episodes of right shoulder pain movement and overhead activity. He had full range of motion of the neck and right shoulder in all planes. However employee's bilateral hip and low back pain had increased during functional movement patterns during the final two sessions and he continued to experience increasing warmth and numbness into both legs and the lumbar spine with prolonged walking on the treadmill. (Claimant's Exhibit X, Pages 197 \& 210-11)
On September 11, Dr. Walentynowicz reexamined claimant who reported back pain with radiation into the buttocks and posterior thighs. Dr. Walentynowicz reviewed the MRI with Mr. Hampson and advised him that it showed a left-sided disk protrusion. He recommended referral to a neurosurgeon. (Claimant's Exhibit FF, Page 4)
On September 15, 2002 claimant sought treatment from the St. Joseph Health Center emergency room for low back pain. Claimant told the physician that he had two herniated disks and could not take the pain; he requested something until his doctor's appointment. He was given an injection of Dilaudid and Phenergan and prescribed Vicodin and Lortab, and Soma. (Claimant's Exhibit U, Pages 16-21)
Dr. John E. Krettek, a neurosurgeon, examined claimant on September 16, 2002. Mr. Hampson reported low back and bilateral hip pain posteriorly and numbness over the anterior thighs. Dr. Krettek reviewed the MRI and opined that it showed a central and left herniation at L4-5 and a central herniation at L5-S1. He diagnosed claimant with neck pain, depression of the right biceps with complaint of right shoulder pain, low back pain and bilateral leg numbness. He prescribed a Medrol DosePak followed by Naprosyn and physical therapy. (Claimant's Exhibit C, Pages $1 \& 5)$ Dr. Krettek ordered an MRI of claimant's cervical spine which was performed on September 18. The radiologist reported that it showed a central disc protrusion at C4-5, a mild central disc protrusion at C5-6, and mild degenerative changes. (Claimant's Exhibit C, Page 32)
After claimant reported increasing back symptom, Dr. Krettek arranged for claimant to received an L4-5 epidural steroid injection on October 8. On October 25 claimant reported that his back pain had become so severe and incapacitating that he was not able to sit or stand. He was more comfortable in bed. He also reported tingling in both legs. Dr. Krettek recommended a two-level lumbar discectomy. (Claimant's Exhibit C, Pages 1, 5 \& 6)
On October 29, 2002 Dr. Krettek performed a laminotomy of S1 and noted a large broad bulging disk at L5S1. He removed most of the disk material. After performing an inferior laminotomy at L4 on the left and a superior laminotomy at L5 on the left, he noted that the L5 nerve root had a very high take-off. He removed the inferomedial facet and decompressed the nerve root in the lateral recess. He noted that the disk was bucked back, but not herniated. No disk material was removed at L4-5. (Claimant's Exhibit C, Pages 9-10)
Dr. Krettek reexamined claimant on December 9, 2002. Claimant reported that his back pain was not as severe, that his greatest pain was over the left buttock, that the right leg symptoms had resolved, and that he had occasional left leg paresthesia. He also reported that two weeks earlier he experienced an episode of not being able to move his left arm or leg. Dr. Krettek opined that it was related to the brain and recommended that he see his private physician. Dr. Krettek did not record any complaints regarding the right shoulder or neck. He switched employee's pain medication from Vicodin to Robaxin. (Claimant's Exhibit C, Pages 11-12)
Dr. Krettek reexamined claimant on January 20, 2003. Claimant reported that he had minimal back soreness, but continued left hip pain. Dr. Krettek did not record any complaints regarding the right shoulder or neck. Sensory
examination revealed some decrease in the L5 and S1 dermatomes. Claimant reported that he was not taking pain medication. He also told Dr. Krettek that he had suffered a small stroke, was hospitalized at Barnes Hospital in late December, was found to have bilateral carotid stenosis and underwent a right carotid endarterectomy. (Claimant's Exhibit C, Pages 13-14) On March 6, 2003 Dr. Krettek noted that claimant's physical therapy was being delayed because of the stroke. (Claimant's Exhibit C, Pages 15-16) On March 20, 2003 Dr. Krettek noted that claimant's physical therapy was being delayed because of his carotid artery disease. Claimant reported no back pain and occasional left hip aching. He was taking an occasional Vicodin. Dr. Krettek did not record any complaints regarding the right shoulder or neck. Claimant underwent x-rays of the hip and pelvis, which were normal, an MRI of the left hip, which was normal, and a bone scan, which showed degenerative changes in his feet. (Claimant's Exhibit C, Pages $17-18 \& 33-36)$
Dr. Krettek reexamined claimant on April 21, 2003. Claimant reported left hip pain but no back pain. He told Dr. Krettek that he had undergone a left carotid endarterectomy and suffered a stroke postoperatively. Physical therapy was again delayed to allow his stroke residual to clear. Dr. Krettek recommended orthopedic evaluation of the hip. On May 19, 2003 Dr. Krettek prescribed physical therapy. Dr. Krettek did not record any complaints regarding the right shoulder or neck during either examination. (Claimant's Exhibit C, Pages 20-21)
Claimant began physical therapy on May 24, 2003 at Team-Work Rehabilitation, Inc. He attended 13 sessions through June 18. Exercises included the use of both upper extremities. The therapist documented complaints of low back and left hip pain, but did not record any complaints regarding the right shoulder or neck. Exercises included the use of both upper extremities. (Claimant's Exhibit DD, Pages 213-18 \& 232-33)
On June 19, 2003 Dr. Krettek indicated that claimant told him and the physical therapy records documented that he had suffered an increase in low back pain on June 18, while doing a stand-up lift. Dr. Krettek discontinued that exercise, but continued physical therapy for another month. He had a "very frank discussion with [employee] about his ability to return to a labor occupation." On July 17 Dr. Krettek noted that claimant continued to have left hip pain. He did not record any complaints regarding the right shoulder or neck during either examination. He prescribed a sacroiliac stabilization brace and work hardening activities. (Claimant's Exhibit C, Pages 22-23)
Claimant attended 19 additional sessions through August 1. Exercises included the use of both upper extremities. The therapist documented complaints of low back and left hip pain, but did not record any complaints regarding the right shoulder or neck. (Claimant's Exhibit DD, Pages 218-224 \& 235-37)
On August 4, 2003 claimant reported that he experienced more back pain two weeks earlier after walking up a steep hill and that he continued to have significant pain in his left hip. Dr. Krettek again recommended an orthopedic evaluation. He prescribed Ultracet for pain and additional physical therapy. He also recommended a return to light duty. On August 29 Mr. Hampson complained that lifting and weightbearing activities increased his left hip pain. Dr. Krettek noted hyperreflexia and sensory dysfunction on the left side from the small stroke. He did not record any complaints regarding the right shoulder or neck during either examination. Dr. Krettek opined that claimant had reached maximum medical improvement from the lumbar disk surgery and released him to return to work "with permanent restrictions of no lifting greater than 50 pounds, no lifting from below waist level, and no repetitive bending, lifting, or twisting." (Claimant's Exhibit C, Pages 24-26)
Claimant attended 14 additional sessions through September 10. Exercises included the use of both upper extremities. The therapist documented complaints of low back and left hip pain, but did not record any complaints regarding the right shoulder or neck. (Claimant's Exhibit DD, Pages 218-230 \& 239)
Dr. Joseph R. Ritchie, an orthopedic surgeon, examined Mr. Hampson on September 12, 2003 for complaints of left hip pain which radiated down his left leg to his foot and ankle. Dr. Ritchie concluded that there was no evidence on diagnostic testing or physical examination of any problem coming from the claimant's hip or leg. He opined that claimant's pain was coming from his back and might be due to continued compression or to residual from his presurgery radiculopathy. (Claimant's Exhibit Y, Pages 28-29)
On December 12, 2003 claimant sought treatment from the St. Joseph's Health Center emergency room for
complaints of stabbing pain in the center of his low back and radiculopathy into the left leg. He was out of Vicodin. He was diagnosed with chronic back pain with left radiculopathy, given an injection of Dilaudid and Vistaril and prescribed Vicodin. (Claimant's Exhibit U, Pages 25-31)
Due to ongoing pain complaints claimant returned to Dr. Krettek on February 2, 2004. Mr. Hampson told Dr. Krettek that he had developed pain extending over the entire leg to the heel and sole of the foot and into the toes. He had no right leg pain. Dr. Krettek did not record any complaints regarding the right shoulder or neck. Sensory examination showed mild decrease to touch and pin over L4 and L5 and marked decrease over the S1 dermatome in the foot. He ordered lumbar x-rays, a lumbar MRI and a myelogram which were performed on February 3, 2004. The radiologist reported that the MRI showed post-operative changes on the left at L5-S1 consistent with scar tissue and a central disk protrusion to the right and posterior disk bulging and central protrusion to the left at L4-5. X-rays showed degenerative disk disease and degenerative disk disease at L4-5 and L5-S1. The CT post-myelogram showed some disk protrusion lateralizing to the left at L5-S1 and degenerative disk disease at L4-5 with a diffusely bulging disk and osteophyte formation lateralizing to the left. (Claimant's Exhibit C, Pages 27-29 \& 37-43)
On February 20, 2004 Dr. Krettek reviewed the various diagnostic studies and opined that claimant had an anterior extradural defect, a bulge suggesting a disk herniation at L4-5 and a prominent defect of the left S1 nerve root probably related to the osteophyte. He opined that S1 nerve root impingement could explain employee's symptoms. Though he recommended another surgical decompression, he also suggested a second opinion. (Claimant's Exhibit C, Pages 30-31)
On March 15, 2004 claimant sought treatment from the St. Joseph's Health Center emergency room for complaints of sharp and burning pain in the center of his low back. He was diagnosed with chronic back pain and acute myofascial strain, given an injection of Dilaudid and Vistaril and prescribed Flexeril. (Claimant's Exhibit U, Pages 35-40)
Employer requested Dr. Michael C. Chabot, an orthopedic spine surgeon, to evaluate Mr. Hampson. He did so on March 17, 2004. Employee complained of back and left hip pain radiating into the left foot. He indicated that he was taking 3 to 4 Vicodin a day. He did not complain any pain in his neck or right shoulder. Dr. Chabot reviewed the medical records and the recent diagnostic studies. Dr. Chabot impression was lumbar radiculopathy and disc degeneration. Dr. Chabot's recommended a lower extremity EMG and nerve conduction study and selective nerve root injections. He noted that he found no clear evidence of neural compression to account for his complaints. He stated the employee could return to limited work duties, with no lifting of more than 30 or 40 pounds. (Claimant's Exhibit FF, Pages 2-8)
On April 21, 2004, Dr. Patricia Hurford performed an EMG and nerve conduction study. She concluded that the studies showed chronic left L5-S1 radiculopathy primarily in the L5 nerve root distributions with no evidence of ongoing denervation in any of the L5-S1 supplied muscles. (Claimant's Exhibit FF, Pages 9-16)
On April 23, Dr. Chabot reviewed Dr. Hurford's studies and recommended selective nerve root injections. (Claimant's Exhibit FF, Page 17) Claimant underwent L5 and S1 nerve root injections on May 27, 2004. (Claimant's Exhibit FF, Page 577)
Dr. Chabot reexamined Mr. Hampson on May 28, 2005. Claimant told him that he had not obtained any significant improvement in his symptoms with the selective nerve root injections. Dr. Chabot opined that claimant had chronic post-laminectomy symptoms which were unlikely to improve with further surgery. He recommended referral to a pain management specialist. (Claimant's Exhibit FF, Page 19)
Dr. John D. Graham, a pain management specialist, examined claimant on July 14, 2004. His assessment was chronic sciatica. He noted that a self-administered psychologic test was given to the patient, the results of which showed a mild elevation in the somatization scale into the clinical range. He prescribed Naprosyn, Neurontin, and Ultram for pain and Elavil as a sleep aid and discontinued the Vicodin. (Claimant's Exhibit FF, Pages 23-25) On August 11 Claimant reported that his pain had not increased, but he still had trouble sleeping at night. He was advised not to take naps during the day. Dr. Graham discontinued the Elavil and prescribed Trazadone. (Claimant's Exhibit FF,
Dr. Graham reexamined claimant on September 1, 2004. He reported that claimant had gone to the emergency room on August 25, 2004 and received an injection of Dilaudid and Vistaril without first contacting him. Dr. Graham indicated that claimant was not taking his medications as directed by him and had been adjusting them on his own. Dr. Graham decided to discontinue treating him. (Claimant's Exhibit FF, Pages 27-28)
Dr. Chabot reexamined claimant on September 30, 2004. Dr. Chabot's impression was chronic back pain with radiculitis and failed back syndrome. He recommended that Dr. Schmidt, a pain management specialist, examine employee. He returned claimant to limited work duties and no lifting of more than 35 to 40 pounds. (Claimant's Exhibit FF, Pages 29-30)
On April 18, 2005 ALJ Cornelius T. Lane issued a temporary award in which he ordered employer to retain a neurosurgeon with Neurosurgical Associates to perform the surgery recommended by Dr. Krettek. (Claimant's Exhibit J)
Employer retained Dr. Michael Boland, a neurosurgeon, to treat claimant's lumbar spine. Dr. Boland examined Mr. Hampson on July 11, 2005. Employee reported that he was experiencing a burning, sharp pain in the center of his back across his hips and down the left leg. He reported that it occurred daily and lasted all day and night. He indicated that it worsened with standing, walking, and sitting, and was relieved with lying down on his right side with a pillow between his knees. He did not complain any pain in his neck or right shoulder. Dr. Boland's impression was back and left buttock pain related to a lumbar radicular syndrome. On reviewing his diagnostic studies, Dr. Boland ordered an MRI. (Claimant's Exhibit Y, Pages 47-51 \& 53)
Claimant underwent an MRI of the lumbar spine on August 1, 2005. It showed prominent diffuse degenerative change of the L5-S1 disk with no definite evidence of recurrent disk herniation and prominent diffuse degenerative change of the L4-5 disk with evidence of slight focal lateralization to the left. (Claimant's Exhibit Y, Pages 55-58) Dr. Boland reviewed the MRI films on August 8 and concluded that there were degenerative changes at L5-S1, but no recurrent disk herniation, and that there was a left-sided disk herniation at L4-5 and severe left L5-S1 neuroforaminal stenosis. Dr. Boland recommended a revision decompressive laminectomy at L4-5 and L5-S1 with a facetectomy on the left at L5-S1, accompanied by a posterior spinal fusion at L4-5 through S1. When he discussed the films with Mr. Hampson he described degenerative disk disease at L4-5 and L5-S1 and recurrent disk herniations at both levels with osteophytic narrowing of the lateral recess on the left, all of which was causing his back and left leg pain. Claimant opted for surgery. (Claimant's Exhibit Y, Pages 59-61)
On September 9, 2005, Dr. Boland performed surgery on claimant's back. During the surgery he noted that there was abundant scar tissue, mostly at L5-S1, and a large bone spur coming off of the facet joint at L5-S1 compounding the neuroforaminal stenosis. He noted that the ligamentum flavum was calcified and indenting the margin of the S1 nerve root. This was resected. He incised the disk spaces at L4-5 and L5-S1, removing all of the nuclear material. He then completed the bilateral interbody fusion with grafts and pedicle screw instrumentation from L4-5 and L5-S1. (Claimant's Exhibit Y, Pages 65-67)
Claimant followed up with Dr. Boland on October 17, 2005. He was noted to be doing well. On December 6, 2005, he followed up again with Dr. Boland and reported that he was able to stand upright much longer periods of time. He had been walking about half a block before the onset of pain in his left hip. However, he reported increased pain and morning stiffness. Dr. Boland prescribed Norflex and Vicodin. (Claimant's Exhibit Y, Pages 73 \& 75)
Dr. Boland reexamined claimant on January 18, 2006. This time employee denied any lower extremity pain. He noted some intermittent stiffness in the back, with occasional pain in the left hip, especially if he tried to walk more than two blocks. At this time Dr. Boland referred him for physical therapy. (Claimant's Exhibit Y, Page 76 \& 78)
Mr. Hampson was evaluated at Team-Work Rehabilitation, Inc. on January 23, 2006. The therapist noted that claimant rated his pain as 2 to 3 out of 10 and up to 7 to 8 out of 10 with activity. He reported morning stiffness and a burning pain in his hip. The pre-surgery numbness and tingling in his legs had improved. (Claimant's Exhibit Y, Pages
Dr. Boland reexamined claimant on February 23, 2006. Claimant complained of discomfort in low back and pain in his left hip extending down to the foot with extended walking. He was taking Norflex twice a day and Vicodin 0 to 3 per day. Dr. Boland noted that claimant walked well on his heels and toes; his gait was nonantalgic. There was no tenderness in the paralumbar musculature. He prescribed additional physical therapy.(Employer's Exhibit 2, depo ex 2)
Claimant returned to Dr. Boland on April 3, 2006. Dr. Boland reported that claimant had completed 30 physical therapy sessions. He noted that employee's range of motion had improved. Employee was still having pain in the low back, especially in the left buttock; the pain extended into the leg if he walked too long or stood too long. Employee reported taking 5 to 6 Vicodin per week. On examination Dr. Boland noted some tightness in the paraspinal muscles on the left. Heel to toe walking was normal. Straight leg raising showed some hamstring tightness at 45 degrees with some pain in the left buttock. Dr. Boland ordered a CT scan to check the integrity of the fusion. (Employer's Exhibit 2, depo ex 2)
On April 4, 2006, Dr. Boland noted that while claimant was not at maximum medical improvement, he could return to work with lifting restrictions of 20 pounds maximum and no highly repetitive bending, stooping or twisting. (Employer's Exhibit 2, depo ex 2)
Dr. Boland reported that the CT scan performed on claimant's lumbar spine on April 5, 2006 showed evidence of bridging healing bone between the L4-5 and L5-S1 vertebral bodies. He opined that this was consistent with the development of fusion at both levels. He prescribed work hardening for the next 8 weeks. (Employer's Exhibit 2, depo ex 2)
On June 15, 2006, Dr. Boland reported that claimant had undergone a functional capacity evaluation on June 8. Team-work Rehabilitation, Inc. had scheduled two days for the evaluation. Although claimant completed the first day of testing, he was unable to complete any testing on the second day because of pain complaints. Based on the results of the functional capacity evaluation, Dr. Boland concluded that claimant had reached maximum medical improvement. He gave employee permanent restrictions of 20 pounds lifting frequently, 10 pounds lifting occasionally with no repetitive bending and no overhead work. (Employer's Exhibit 2, depo ex 2)
