Claimant was taken by ambulance to St. Anthony's Medical Center where he was admitted for a period of five days. X-rays of the right tibia and fibula showed a comminuted fracture in the tibial plateau and proximal tibial shaft and a mildly displaced fracture involving the medial malleolus of the right ankle. A CT scan of the right knee also showed a nondisplaced fracture involving the fibular head extending into the proximal tibial fibular joint. X-rays of the left ankle showed a mildly displaced fracture involving the lateral malleolus. His left ankle was placed in a cast. ${ }^{[2]}$ X-rays of the dorsal spine showed a compression of deformity of T12 with 30 % to 40 % loss of height anteriorly. A CT Scan of the lumbar spine showed the compression fracture of the superior endplate of T12. Additional findings in the lumbar spine included a vacuum phenomenon at L3-4 associated with a broad based disc protrusion, seven millimeters anterolisthesis of L4 on L5 associated with mild spinal stenosis, and discogenic degenerative disease at L2-3, L3-4, and L4-5. ${ }^{[3]}$ (Claimant's Exhibits D, Pages 9, 15, 18-19, \& 22-23 and E, Pages 3-16) On September 24, 2003 employee underwent an open reduction and internal fixation of the comminuted right tibial plateau fracture by Dr. David B. Fagan. Claimant was nonweightbearing on discharge and was taking Percocet for pain control. He was to see Dr. Fagan in three weeks. (Claimant's Exhibit D, Page 24 \& 26)
On October 2, 2003 Dr. John D. Graham evaluated employee for pain management. Employee was in a wheelchair. Claimant advised Dr. Graham of his past history of drug and alcohol abuse, stating that he would like to remain clean and sober if at all possible. Dr. Graham prescribed OxyContin for 12 hour pain relief. On October 14 employee reported that the OxyContin was controlling his pain very well. He complained of some low back discomfort in the early morning hours. Dr. Graham thought it was from the compression fracture. He prescribed Lidoderm patches for the low back. (Claimant's Exhibit F, Pages 9-10 \& 13-14)
Dr. Fagan reexamined claimant on October 14. Employee was in a wheelchair. X-rays showed healing of the tibial plateau fracture and left ankle fracture. He recommended that employee work on range of motion exercises, but remain nonweightbearing. X-rays of the back showed a compression fracture of approximately 50 % of T12 and a fracture of L5 with spondylolisthesis at L4 and L5. (Claimant's Exhibit F, Page 12)
On November 6, 2003 employee told Dr. Graham that his pain was well controlled, except for some back pain and occasional pain in his right knee. Dr. Graham decreased the dosage of OxyContin and prescribed Celebrex. (Claimant's Exhibit F, Page 20)
Dr. Fagan reexamined claimant on November 6. X-rays of the right tibial plateau and left ankle looked good. He removed both casts and prescribed home physical therapy and weightbearing of no greater than 50 pounds. (Claimant's Exhibit F, Page 21)
Dr. Thomas K. Lee examined claimant's back on November 10. Mr. Lampe complained of pain in his lower back, particularly at L5. Dr. Lee reviewed x-rays which he thought showed acceptable healing. He noted that Dr. Graham was treating him for pain. (Claimant's Exhibit F, Page 26)
On December 4, 2003 Dr. Graham noted that claimant was walking with a cane and not using a wheelchair. Claimant told him that he was doing very well. He was no longer taking OxyContin and only occasionally taking Celebrex and using the Lidoderm patch. Dr. Graham prescribed additional Celebrex for employee to take as needed and discharged employee from his care. (Claimant's Exhibit F, Page 27)
Dr. Fagan also reexamined claimant on December 4, 2003. Dr.Fagan noted that employee had excellent range of motion of his ankle and knee. X-rays showed that his fractures were healing in good position. Dr. Fagan prescribed outpatient physical therapy. (Claimant's Exhibit F, Page 28)
Claimant was evaluated at ProRehab for physical therapy for his lower extremities on December 9, 2003. Employee rated his pain level as 6 on a scale of 1 to 10 . He complained of stabbing pain in the outside of his left ankle and pressuretype pain and stiffness in his right knee. He reported that his lower lumbar pain was worse with sitting and riding and better with lying completely flat in bed. He indicated that back pain restricted his travel over two hours and prevented him from sitting more than 1 hour and often more than $1 / 2$ hour. Claimant was started on a program of ankle and knee exercises. (Claimant's Exhibit L, Pages 7-9 \& 12-15)
On December 10 Mr. Lampe complained to Dr. Lee of tenderness in the T12 region only. X-rays showed healing of the T12 compression fracture. Forward flexion was to 60 degrees without pain. Dr. Lee prescribed physical therapy consisting of gradual progressive range of motion exercises. (Claimant's Exhibits F, Page 30 and L, Page 22)
Claimant attended 10 of 14 scheduled physical therapy sessions through January 2, 2004. He missed 4 sessions due to personal problems including a recurrence of alcoholism. He worked at a high intensity level and demonstrated no adverse reactions to the in-house exercise programs. As of January 2 the therapist thought that employee was making progress. (Claimant's Exhibit L, Pages 37-38)
On January 16 Dr. Lee noted that claimant's forward flexion was to 95 degrees. Mr. Lampe had some tenderness at T10 and L5. Dr. Lee advised him to lift no more than 20 pounds. Dr. Lee recommended work hardening of four hours per day, five days per week. (Claimant's Exhibit F, Page 32)
Dr. Fagan reexamined claimant on January 16, 2004. He noted swelling about the left ankle and good range of motion of the right knee and both ankles. X-rays of the knee and ankle looked good. Dr. Fagan felt that employee could weight bear as tolerated. He agreed with Dr. Lee's recommendation for two additional weeks of work conditioning. (Claimant's Exhibit F, Page 33)
Mr. Lampe underwent a functional evaluation at Farmington Sports and Rehabilitation Center in Farmington, Missouri on January 21, 2004. The therapist noted that he had limited tolerances to prolonged weight bearing positions and increased discomfort in his knees and ankles with prolonged sitting. She noted that he stood with reduced weight bearing through the right lower extremity and had antalgia with walking. He demonstrated signs of discomfort and slowing of movement during transition to and from crouched and squatted postures. He was able to lift 88 pounds from floor to waist and 58 pounds from waist to overhead. She opined that he was functioning in the heavy physical demand level. His primary limiting factors were pain and limitations in range of motion and flexibility in his knees and ankles, limited tolerance to weight bearing postures, including standing, walking, and climbing, and limited material handling tolerances. All symptom magnification testing was negative. (Claimant's Exhibit H, Pages 35 \& 37-39)
Dr. Fagan reexamined Mr. Lampe on February 6, 2004. Mr. Lampe indicated that his main problem was with balance and some pain in his back. He indicated that his knee was not much of a problem. He had full range of motion in the right knee and a little swelling in his leg and ankle. Dr. Fagan advised employee that he could return to work after the additional therapy recommended by Dr. Lee. (Claimant's Exhibit F, Page 34)
Dr. Lee reexamined claimant on February 6. He indicated that claimant had pain in the L4-5 region. X-rays showed a well consolidated fracture at T12, a minimal amount of early degenerative scoliosis at L3-4, and spondylolisthesis of L4 on L5. Dr. Lee restricted him from working on uneven surfaces or pitched roofs and restricted him from prolonged bending or crawling. (Claimant's Exhibit F, Pages 35-36)
Claimant participated in 17 sessions of work hardening through February 19, 2004. Thetherapist noted at the conclusion of the program that Mr. Lampe had continued to make good progress and that he appeared to be able to perform all essential job demands as a sheet metal worker. The therapist again stated that there was an absence of symptom magnification. (Claimant's Exhibit H, Pages 43-44)
Dr. Lee reexamined claimant on February 23, 2004. Mr. Lampe reported pain with his work hardening and swelling in the left ankle. On examination Dr. Lee noted mild to moderate decreased inversion of both ankles and tenderness at T12 and L5. As claimant's request Dr. Lee released him to full duty and prescribed Celebrex. (Claimant's Exhibit F, Page 37)
Claimant returned to Dr. Lee on March 22, 2004. Claimant indicated that he was working cleaning film off 10 feet pieces of sheet metal. On examination he was tender from L2 to L4. He reported that Celebrex was not adequate. He nevertheless wanted to keep working. Dr. Lee recommended continued home exercises. (Claimant's Exhibit F, Page 39)
Dr. Fagan also reexamined claimant on March 22. On examination employee had well-developed quadriceps and calf musculatures bilaterally. He had swelling in his right knee and left ankle. His range of motion of his knee and ankle looked good. Dr. Fagan thought that claimant would continue to improve. (Claimant's Exhibit F, Page 40-41)
Dr. Ronald Hertel, an orthopedic surgeon, examined Mr. Lampe on April 13, 2004 atthe request of employee's attorney. Based on his examination and review of the medical records, he opined that while claimant's anterior subluxation of L4 on L5 preexisted the work accident of September 22, 2003, the work accident aggravated that condition. He opined that it also caused compression fractures to the vertebral bodies of T12 and L1. ${ }^{[4]}$ He recommended that claimant undergo a lumbar myelogram. He opined that the work accident substantially contributed to the need for a myelogram and consideration for surgery. (Claimant's Exhibit A, depo ex 2, pp 5-6)
Dr. Lee reexamined claimant on May 17, 2004. Claimant was still working though he was still experiencing pain. Dr. Lee felt that he was a maximum medical improvement and released with him to full duty. (Claimant's Exhibit F, Page 43)
Dr. Fagan also reexamined claimant on May 17. Mr. Lampe reported that he occasionally felt that his knee was going to give way. X-rays of the knee and ankle showed that his fractures had healed in good position. Dr. Fagan told him that he would continue to improve and that he could take anti-inflammatories. (Claimant's Exhibit F, Pages 44-45)
In response to claimant' request for a surgical referral made to the employer, Dr. Lee on July 13, 2004 recommended an MRI of the lumbar spine. He noted that claimant had a preexisting fracture deformity at L5 and an acute fracture at T12. (Claimant's Exhibit F, Pages 46-47)
An MRI of Mr. Lampe's lumbar spine performed on July 28, 2004 showed grade I anterolisthesis of L4 on L5 with severe central canal stenosis and bilateral neural foraminal stenosis and degenerative disc disease at all lumbar levels with annular disc bulges at the remaining lumbar levels. (Claimant's Exhibit F, Page 49)
Dr. Lee reexamined claimant on October 27, 2004. Mr. Lampe told him that he was working full duty, but was getting tired of hurting every day. He complained of pain in the back and legs. Dr. Lee opined that Mr. Lampe's current ongoing complaints were due to an aggravation of his preexisting lumbar spine condition. He recommended an epidural steroid injection. (Claimant's Exhibit F, Pages 50-51)
Dr. David G. Kennedy, a neurosurgeon, examined employee on January 26, 2005. Mr. Lampe told Dr. Kennedy about the September 24, 2003 fall and his increasing low back complaints, especially after returning to work. His principal complaints were persistent pain in the lower lumbar area with radiating pain into both legs, the left greater than the right. On examination claimant's straight leg raising test was positive bilaterally at 45 degrees. Dr. Kennedy reviewed the MRI of the lumbar spine performed on May 1, 2001, the CT scan of the lumbar spine performed on September 23, 2003, and the MRI of the lumbar spine performed on July 28, 2004. ${ }^{[5]}$ Dr. Kennedy diagnosed claimant with a listhesis at L4-5 with significant spinal stenosis at that level and recommended that employee undergo a decompression and fusion at this level. He advised claimant not to lift more than 20 pounds nor to do more than occasional bending, twisting, or stooping prior to further treatment. (Claimant's Exhibit M, Pages 6-8)
Dr. Hertel also reviewed the July 28, 2004 MRI. He indicated that it showed that there was significant pressure on the dura at the L4-5 level and significant encroachment on the L4-5 nerve roots and the dura. He opined that claimant was a candidate for decompression and spinal fusion at the L4-5 level. (Claimant's Exhibit A, depo ex 4)
Claimant underwent a lumbar myelogram and CT scan post-myelogram on April 7, 2005. Theyshowed Grade I spondylolisthesis at L4-L5 with moderate to several spinal canal stenosis at that level. There was nonfilling of both L5 nerve root sheaths. There was a mild broad focal lateralization to the right of the L4-L5 disc which encroached with mild compromise into the right L4 foramen. There was no significant abnormality at L5-S1. There were diffuse degenerative disc
changes at L2-L3 and L3-L4. Old compression deformities were noted at T12 and L5. (Claimant's Exhibit M, Pages 9-10) Lumbar spine x-rays taken on April 18, 2005 showed minimal anterolisthesis of L4 on L5, compression deformities at T12 and L5, spondylitic changes and changes of degenerative disk disease in the mid-lumbar spine, and facet disease in the lower lumbar spine. (Claimant's Exhibit M, Page 13)
On April 25, 2005 Drs. David Robson and David Kennedy performed a bilateral lumbar laminectomy, facetectomy and foraminotomy at L4-L5 and fusion with insertion of cage and pedicle screw fixation. Dr. Kennedy noted that the L4-5 facets were severely enlarged. (Claimant's Exhibit M, Pages 20-23)
Dr. Kennedy reexamined Mr. Lampe on May 25. Employee told him that he was not taking any pain medication and having only minimal leg pain. He was advised to walk as tolerated. On July 19 Mr. Lampe told him that he had some aching pain in his lower lumbar area and decreased range of motion. Dr. Kennedy thought that it was due to persistent muscle and ligament aggravation. He initiated physical therapy. He also complained of pain and crackling in his left knee. Dr. Kennedy advised him to see Dr. Fagan. (Claimant's Exhibit M, Pages 27 \& 29)
On July 28, 2005 claimant was evaluated for physical therapy for his low backat Farmington Sports and Rehabilitation Center. The therapist noted that employee had pain in his low back, decreased truck range of motion, decreased flexibility, decreased awareness of pain causing activities and decreased core strength/lumbar stabilization. (Claimant's Exhibit H, Pages 50-51) Claimant attended attending 15 sessions of physical therapy through August 29, 2005. The therapist noted that claimant reported much less low back pain, but more right knee and left ankle pain. He met nearly all of his physical therapy goals. She recommended work hardening prior to employee returning to work. (Claimant's Exhibit H, Page 57)
On August 30 Mr. Lampe told Dr. Kennedy that his range of motion had improved. Dr. Kennedy wanted to start him on a work conditioning program. (Claimant's Exhibit M, Page 32)
Dr. Fagan reexamined claimant's right knee and left ankle on August 30, 2005. Claimant reported that his knee started acting up during physical therapy. He complained of a lot of popping and pain in the knee and pain and swelling in the left ankle. On examination there was a lot of swelling in his ankle and a lot of crepitus in the right knee. X-rays of the left ankle revealed an old fracture of the distal fibula which had healed in good position and degenerative spurs at the inferior pole of the fibula. X-rays of the knee showed some arthritic changes. Dr. Fagan recommended glucosamine chondroitin sulfate and anti-inflammatories. (Claimant's Exhibit F, Pages 52-53)
Claimant underwent a work hardening evaluation at Farmington Sports and Rehabilitation Center on September 6, 2005. His symptom magnification testing was negative. He presented with limited lumbar flexibility and intermittent symptoms in the lower extremity since his back surgery. He reported that prolonged sitting and bending caused back and leg discomfort. (Claimant's Exhibit H, Pages 59 \& 76-77) Claimant attended 13 sessions of work hardening through September 27, 2005. The therapist concluded that Mr. Lampe demonstrated improved tolerance to material handling, but continued to exhibit limited positional tolerances to bending, sitting and sustained overhead postures. He continued to have lower extremity flexibility. He made slight improvement in lumbar flexibility, but deficits remained. (Claimant's Exhibit H, Pages 88-90)
Dr. Kennedy reexamined claimant on September 28, 2005. Mr. Lampe indicated that he was still having quite a bit of aching back pain particularly with prolonged standing or sitting. Dr. Kennedy indicated that employee had done well from the standpoint of strengthening, but that certain activities aggravated his pain. (Claimant's Exhibit M, Page 35)
Dr. Fagan also reexamined claimant on September 28. Claimant reported that while his ankle had gotten much better, his knee was about the same. He walked with a slight limp. Dr. Fagan again recommended a cortisone injection. On October 27, 2005 claimant reported that he experienced some relief for two or three days after which his pain returned. He complained of a grinding sensation. Dr. Fagan suspected some articular cartilage damage and recommended arthroscopic surgery. (Claimant's Exhibit F, Pages 55-57)
Dr. Kennedy also reexamined Mr. Lampe on October 27. employee indicated that he was better, but that he still had some aching pain. His forward flexion was reduced about 50 %. Straight leg raising was negative. Xrays showed incorporation of fusion material. Dr. Kennedy felt that employee was a maximum medical improvement. He advised him not to lift more than 40 pounds and to not do more than occasional bending, twisting, or stooping. (Claimant's Exhibit M, Pages 38-40)
Claimant underwent arthroscopic surgery on the right knee on November 2, 2005. Dr. Fagan found extensive articular
cartilage damage of the femoral trochlea, tears of the posterior horns of the lateral and medial menisci, mild articular cartilage damage to the medial femoral condyle, and a large flap of articular cartilage in the lateral compartment. He performed medial and lateral meniscectomies and chondroplasty of the femoral trochlea, lateral tibial plateau and medial femoral condyle. (Claimant's Exhibits F, Page 59-60 and Substitute S, Pages 1-2) Dr. Fagan reexamined claimant on November 9 and December 6, 2005, and January 3, 2006. Dr. Fagan told claimant that he found a rather significant amount of arthritis in right his knee. He thought that the knee would function fairly well, though it would never be completely normal. On January 3, 2006 claimant was walking without an assistive device. He could fully extend his knee and bend it back approximately 130 degrees. Dr. Fagan opined that claimant's knee was doing fairly well and that it would continued to improve. He told Mr. Lampe that he would see him on an as needed basis. Dr. Fagan did not give claimant any permanent work restrictions. (Claimant's Exhibit F, Pages 61-65)
