At the request of the employee's attorney, Dr. David Volarich performed an independent medical examination and evaluation of the employee on March 13, 2009.
Dr. Volarich is a board-certified radiologist, and is currently licensed to practice medicine by the State of Missouri.
As part of his review of medical records supplied to him by the employee's attorney, Dr. Volarich noted that X-rays taken at St. Francis Medical Center of the employee's low back on the day after the work-related accident demonstrated moderate posterior wedging at the L5 level in the employee's lumbar spine, with a 40 % loss of the L5 vertebral body height. Dr. Volarich also noted that lumbar spine x-rays taken September 14, 2002, demonstrated an apparently solid fusion of the employee's lumbar spine with no compression deformity, a finding which Dr. Volarich believes "contrast starkly" with the x-rays taken the day after the work-related accident.
Dr. Volarich made the following observations regarding the employee's pre-existing medical conditions:
Low back: On 9/17/79, he underwent surgical decompression with the removal of the posterior elements of L5, exploration of the nerve roots of L5 and S1 on the left and a fusion of L4 to the sacrum with bone from the iliac crest. On 1/18/81, he was readmitted for neurolysis and revision of the fusion of L4 to the sacrum. On 10/8/81, he was readmitted for treatment of a failed fusion of L4 in the sacrum. He underwent revision of the fusion of L5 to S1 with another iliac crest bone graft.
Right knee: On 5/18/73, he underwent anterior and posterior exploration of the medial aspect of his right knee with removal of the medial meniscus for persistent knee pain and "clicking". On 2/9/82, he underwent a right knee arthroscopy with repair of a medial collateral ligament. On 4/8/97, he underwent a right knee arthroscopy with patellofemoral chondroplasty and debridement of the medial and lateral meniscal remnants.
Left knee: On 6/21/78, open medial menisectomy on his left knee for intractable left knee pain after jumping off a truck. On 4/4/00, he underwent left knee arthroscopy with partial medial menisectomy, debridement of the patellofemoral and medial compartments with synovial biopsy. Following this procedure, his pain in his left knee worsened considerably and his advanced degenerative joint disease progressed.
Right shoulder: On 7/97, slipped on a patch of oil in a grocery store in Houston, and on 7/8/97, he underwent right shoulder arthroscopy with distal clavicular excision, acromioplasty, debridement of the glenoid labrum and mini right open rotator cuff repair. In 1999, he was chasing a robber in a store in Houston and attempted to stop him with his right arm and sustained another injury to his right shoulder. On 7/13/99, he underwent right shoulder arthroscopy with arthroscopic debridement and revision of a rotator cuff tear.
In 1967 while in the military, he fell down approximately 50 stairs. He sustained an injury to his neck.
He was involved in a truck accident in 11/72 and sustained an injury to his neck and subsequently, on 3/10/74, underwent C5-6, and C6-7 fusions with iliac crest bone grafting.
Dr. Volarich reviewed voluminous medical records, interviewed the employee and performed a physical examination of the employee as part of his independent evaluation. Dr. Volarich's objective findings upon examination of the employee for his work-related injuries and pre-existing conditions included:
- Asymmetric bulk of the upper extremities and atrophy;
- Weakness in motor testing;
- A limp favor the left leg;
- Difficulty bearing weight on the left leg;
- Inability to perform certain gait maneuvers;
- Various diminished ranges of motion of both the cervical and lumbar spines;
- Muscle spasm;
- Surgical scars consistent with the Employee's history of prior surgeries;
- Positive signs upon impingement testing;
- Positive signs upon Phalen's testing;
- Positive signs upon provocative testing.
Dr. Volarich diagnosed and rated the following injuries and disabilities as a result of the work-related accident:
- 20 % of the body as a whole due to compression fracture at L5 with 40 % loss of vertebral height, and aggravation of the employee's lumbar radicular syndrome with worsening left leg radiculopathy.
- 15 % of the body as a whole at the cervical spine due to aggravation of the employee's cervical radicular syndrome with worsening left upper extremity radiculopathy.
Dr. Volarich also diagnosed and rated multiple pre-existing disabilities, including, but not limited to:
- 50 % of the body as a whole at the level of the lumbosacral spine based, in part, upon the employee's prior surgeries.
- 35 % of the body as a whole at the level of the cervical spine to the employee's prior surgeries.
- 45 % of the right upper extremity at the level of the shoulder based, in part, upon the employee's prior surgeries.
- 5 % of the right upper extremity at the level of the hand based, in part on the employee's prior surgery.
- 65 % of the left lower extremity at the level of the knee based, in part, upon the employee's prior surgeries.
- 75 % of the right lower extremity at the level of the knee based, in part, upon the employee's prior surgeries.
According to Dr. Volarich, the employee's pre-existing disabilities are hindrances or obstacles to his employment or re-employment, a synergistic enhancement has occurred in which
the combined totality of the employee's disability is greater than the sum of its parts, the degree or percentage of disability caused by the combination of the employee's work-related and preexisting disabilities is substantially greater than that which would have resulted from the workrelated injury considered alone and by itself, and the amount of the employee's disability resulting from the combination of the work-related and pre-existing disabilities is greater than the sum or the amount of those disabilities when each disability is considered separately.
Dr. Volarich is reasonably certain that the employee is permanently and totally disabled as result of the combination of his work-related and pre-existing disabilities.
Dr. Volarich noted that medical records indicate that the Employee was felt to be stable on September 9, 2005. He noted that the Employee was at maximum medical improvement as of the date of his independent evaluation.
Dr. Volarich recommended numerous permanent physical restrictions for the Employee, including:
With regard to work and other activities referable to the spine:
- Limit all bending, twisting, lifting, pushing, pulling, carrying, climbing and other similar tasks to an as needed basis.
- Do not handle any weight greater than 10-15 pounds, and limit this task to an occasional basis assuming proper lifting techniques.
- Do not handle weight over his head or away from the body, nor carry weight over long distances or uneven terrain.
- Avoid remaining in a fixed position for any more than about 20 minutes at a time including both sitting and standing.
- Change positions frequently to maximize comfort and rest when needed including resting in a recumbent fashion.
With regard to work and other activities referable to the spine prior to 9/6/05:
- Limit repetitive bending, twisting, lifting, pushing, pulling, carrying, climbing and other similar tasks to an as needed basis.
- Do not handle any weight greater than 35 pounds, and limit this task to an occasional basis assuming proper lifting techniques.
- Do not handle weight overhead or away from the body, nor carry weight over long distances or uneven terrain.
- Avoid remaining in a fixed position for any more than about 60 minutes at a time including both sitting and standing.
- Change positions frequently to maximize comfort and rest when needed.
With regard to work and other activities referable to the lower extremities:
- Avoid all stooping, squatting, crawling, kneeling, pivoting, climbing, and all impact maneuvers.
- Be cautious navigating uneven terrain, slopes, steps, and ladders especially when handling weight; handle weight to tolerance.
- Limit prolonged weight bearing including standing or walking to 30 minutes or to tolerance. Place a pad on any surface upon which he may kneel.
With regard to work and other activities referable to the right shoulder,
- Avoid all overhead use of the right arm and prolonged use of the right arm away from the body, especially above chest level.
- Minimize pushing, pulling and particularly traction maneuvers with the right upper extremity.
- Do not handle weights greater than about 5 pounds with the right arm extended away from the body or overhead, and limit these tasks to as needed or as tolerated.
- Handle weight to tolerance with right arm dependent, assuming proper lifting techniques, but, in general, limit lifting to 15-20 pounds with the right arm alone.
With regard to work and other activities referable to the right hand, limitations were not required.
