Ms. Johnson did not receive treatment for her neck and cervical spine during the period she treated with Dr. Mutchler from April 2003 to April 2004. Subsequent to treating with Dr. Mutchler, and in light of continuing pain and numbness in her upper extremity, Ms. Johnson requested the employer to provide additional treatment. The employer and insurer, however, declined to provide Ms. Johnson with additional medical care. Consequently, Ms. Johnson sought and obtained medical care with her primary care provider, Michael Hoeman, M.D.
In July 2004, Ms. Johsnson presented to Dr. Hoeman for examination and evaluation with complaints of "progressive pain in the left shoulder to the point where she had lost feeling in the dorsum of her hand and the $4^{\text {th }} and 5^{\text {th }}$ digits of her right hand", and "sensation of numbness and paresthesias involving the left arm.' In light of these symptoms, Dr. Hoeman referred Ms. Johnson to a neurologist with Ferrell-Duncan Clinic for an EMG and nerve conduction velocity study, which the neurologist identified as negative for a peripheral nerve injury or deficit. In light of this diagnostic study, and based on clinical findings, the neurologist felt that Ms. Johnson likely suffered a lower cervical radiculopathy.
Subsequently, in his reports dated October 13, 2004 and November 4, 2004, Dr. Hoeman offered a working diagnosis to include: (1) neck pain; (2) left shoulder pain; (3) paresthesias involving the left arm; and (4) possible cervical radiculopathy involving the left upper extremity. And Dr. Hoeman initiated a treatment plan to include "use of non-steroidal anti-inflammatory medication, skeletal muscle relaxants and physical modalities such as heat." Additionally, Dr. Hoeman noted that treatment included "uses of potent narcotic analgesics for control of her chronic pain" and other treatment may include physical therapy. Further, Dr. Hoeman opined that, based on her history, physical findings, and clinical course, this presenting medical condition is causally related to the March 2003 injury at Wal-Mart while pulling carts apart.
Eventually, in light of continuing complaints of pain, Dr. Hoeman referred Ms. Johnson to Robert Strang, who is a neurosurgeon with Springfield Neurological \& Spine Institute, and who had previously provided consultation to Ms. Johnson for her low back. Additionally, Ms. Johnson underwent an MRI of the cervical spine.
On May 5, 2005, Ms. Johnson presented to Dr. Strang for complaints of pain to her neck, shoulder, and arm. In his office note of May 5, 2005, Dr. Strang records the following history,
Ms. Johnson returns today with neck, shoulder and arm pain following an incident at work in March of 2003. She has some documentation with her today from other doctor's visits which do document that she sought medical attention following an injury at Wal-Mart that left her with neck and shoulder pain. Now the pain has traveled further down the arm and is more radicular in nature. The left side is more affected than the right and with distribution is approximately at C6 or C7. Her symptoms are aggravated by activity and are relieved somewhat by rest. She has had shoulder surgery, but continues to have shoulder pain. She denies any recent bowel or bladder changes.
In light of his examination and evaluation of Ms. Johnson, and in light of his review of the MRI, Dr. Strang opined that Ms. Johnson presented with a herniated disc of the cervical spine at C5-C6, and recommended that she undergo an anterior cervical discectomy with fusion and fixation at the level of C5-C6, and this condition presented a risk for spinal cord injury if she did not proceed with a surgery. Dr. Strang further opined that this condition was causally related to the work incident at Wal-Mart. In this context Dr. Strang propounded the following comments:
In reviewing her records it does appear that the symptoms are secondary to a work related injury. She initially had neck pain with radiation to the shoulder and in all likelihood this was an early cervical radiculopathy that has now progressed down the entire upper extremity.
Dr. Strang performed an anterior cervical discectomy with anterior cervical arthodesis on June 17, 2005. This procedure included an anterior cervical arthrodesis at C5-C6 the fixation of an anterior cervical plate, and a tube threaded cervical interbody spacer placement. Dr. Strang provided Ms. Johnson with follow-up treatment, which included office visits, physical therapy, x-rays, and MRI scan. On February 2, 2006 Dr. Strang released Ms. Johnson from his care, with directions to return on a PRN basis.
Notably, in responding to a suggestion that Ms. Johnson presented with an episode of numbness and/or paresthesias while sleeping prior to suffering the March 2003 injury at WalMart, and in responding to the employer/insurer's concerns that Ms. Johnson's presenting medical condition associated with her neck was not causally related to the March 29, 2003 accident, Dr. Strang issued a report dated December 13, 2007. In this report Dr. Strang propounded the following comments:
I am writing this letter in regard to Paula L. Johnson, whom I saw on May 5, 2005 for a neck injury/cervical radiculopathy. She was found to have a C5-6 herniated disc with cervical radiculopathy and significant stenosis at C5-6. She underwent a C5-6 anterior discectomy with fusion on June 17, 2005 due to the work-related injury.
It has come to my attention that several weeks prior to her injury she had an episode of numbness and/or paresthesias while sleeping. It is my opinion that this is unrelated to her C5-6 herniated disc, for which she underwent surgery on June
17, 2005. Indeed she had a similar episode later the same year in November 2005 and this is documented in my note from November 21, 2005. I feel that this is more likely a peripheral etiology and unrelated to the C5-6 process. Furthermore, the fact that it was present both preoperatively and postoperatively, and is related to positioning postoperatively (especially since the patient has had a fusion), would make it unlikely that the positional numbness/paresthesias are related to her herniated disc.
Subsequent to being released from medical treatment by Dr. Strang, Ms. Johnson continued to receive follow-up care from her primary care provider, Dr. Hoeman, and other physicians for multiple medical problems, including conditions predating the March 29, 2003 injury, and new conditions occurring subsequent to being released from medical care by Dr. Strang. Notably, in March 2006 Dr. Putnam diagnosed Ms. Johnson with a tear in the cartilage of her right shoulder. And on March 30, 2006 Ms. Johnson underwent a right shoulder arthroscopic surgery performed by Dr. Putnam. Additionally, in 2006 Ms. Johnson received treatment, including hospitalization, for chest pain and hypertension.
In 2007 and continuing through 2008, Dr. Hoeman provided follow-up treatment primarily for degenerative disc disease involving the lumbar and cervical spine. Additionally, she received treatment or evaluations from Dr. Strang. Dr. Hoeman provided pain management that included maintaining Ms. Johnson "on potent narcotic analgesic agents."
Shane L. Bennoch, M.D., who is a physician certified in disability evaluations through American Academy of Disability Evaluating Physicians, testified by deposition in behalf of the employee. Dr. Bennoch performed an independent medical examination of Ms. Johnson on January 11, 2006. At the time of this examination, Dr. Bennoch took a history from Ms. Johnson, reviewed various medical records, and performed a physical examination of her. In light of his examination and evaluation of Ms. Johnson, Dr. Bennoch opined that in the process of attempting to separate two carts on March 29, 2003, while engaged in her employment at WalMart, Ms. Johnson sustained an injury to her neck and left shoulder which necessitated surgical repair to both her neck and left shoulder.
Notably, in describing the nature of this injury, Dr. Bennoch opined that the injury to the neck involved a herniated disc at the level of C5-C6 "with cervical radiculopathy and cervical myelopathy secondary to delay in diagnosis"; and the injury to the left shoulder involved "impingement syndrome, secondary to a large anterior inferior subacromial spur and ossification of a coracocacromial ligament." The surgery for the neck condition involved a C5-C6 anterior cervical discectomy with anterior cervical arthrodesis and cervical plate fixation. The surgery for the left shoulder involved an open subacromial decompression with a left shoulder subacromial bursectomy. Additionally, Dr. Bennoch opined that the March 29, 2003 injury caused Ms. Johnson to suffer "neuropathic itching secondary to cervical myelopathy, bilateral, severe"; and it caused Ms. Johnson to suffer "depression secondary to her neck and shoulder injuries and subsequent neuropathic itching."
Further, Dr. Bennoch opined that, as a consequence of the March 29, 2003 injury, Ms. Johnson will require medication on a long-term basis for treatment of the neuropathic itching, and physical therapy for treatment of her left shoulder in an attempt to avoid adhesive capsulitis (frozen shoulder). In addressing the question of future medical care, Dr. Bennoch was not of the
opinion that Ms. Johnson will require further surgery for her neck, but should be provided a repeat MRI to make sure there is no other impingement or cord lesion or spinal stenosis that could be causing the bilateral radiculopathy, weakness of the arm, and paraesthesias.
In determining the nature and extent of the disabilities caused by the March 29, 2003 injury, Dr. Bennoch propounded the following opinions:
- Neck. The March 29, 2003 work-related injury caused Ms. Johnson to sustain a permanent partial disability of 35 percent to the body as a whole, referable to the cervical spine. In rendering this opinion, Dr. Bennoch takes into consideration the cervical discectomy and fusion, the residual and significant restriction in range of motion to Ms. Johnson's neck, and the persistent pain she is continuing to suffer, with bilateral cervical radiculopathy involving the ulnar nerves.
- Left Shoulder. The March 29, 2003 work-related injury caused Ms. Johnson to sustain a permanent partial disability of 25 percent to the left shoulder, referable to the surgery for the impingement syndrome. In rendering this opinion, Dr. Bennoch takes into consideration the open subacromial decompression and a subacromial bursectomy, the significant decrease in range of motion and positive impingement signs to her shoulder with pain during those movements and continuing physical therapy in an attempt to retain range of motion.
- Neuropathic Itching. The March 29, 2003 work-related injury caused Ms. Johnson to sustain a permanent partial disability of 20 percent to the body as a whole, referable to neuropathic itching of the skin secondary to a delay in diagnosis of cervical neck disease, associated with nerve damage. In rendering this opinion, Dr. Bennoch takes into consideration Ms. Johnson suffers from severe protracted itching to both arms, severe enough to cause skin lesions secondary to scratching, and has caused Ms. Johnson to take gabapentin in an attempt to help with itching.
- Depression. The March 29, 2003 work-related injury caused Ms. Johnson to sustain a permanent partial disability of 10 percent to the body as a whole, referable to the brain, secondary to depression. In rendering this opinion, Dr. Bennoch takes into consideration Ms. Johnson suffers from persistent depression requiring medication for partial control. (In his deposition, Dr. Bennoch modified this opinion, opining that, prior to March 29, 2003, Ms. Johnson presented with a permanent partial disability of 5 percent to the body as a whole, referable to the brain, secondary to depression; and the accident of March 29, 2003 caused Ms. Johnson to sustain a permanent partial disability of 5 percent to the body as a whole, referable to the brain, secondary to depression.)
In determining the nature and extent of the disabilities predating the March 29, 2003 injury, Dr. Bennoch propounded the following opinions:
- Low Back. Prior to March 29, 2003, Ms. Johnson suffered from a permanent partial disability of 20 percent to the body as a whole, referable to the lumbar spine due to multilevel disk disease and degenerative disk disease. In rendering this opinion, Dr.
Bennoch takes into consideration Ms. Johnson presented with decreased range of motion to the lumbar spine with persistent pain and radiculopathy in both legs.
- Hypertension. Prior to March 29, 2003, Ms. Johnson suffered from a permanent partial disability of 5 percent to the body as a whole, referable to cardiovascular system. In rendering this opinion, Dr. Bennoch takes into consideration Ms. Johnson has been required to take oral medication to control her blood pressure.
- Thoracic Outlet Syndrome. Prior to March 29, 2003, Ms. Johnson suffered from a permanent partial disability of 15 percent to the body as a whole, referable to the chest wall, secondary to obstructive thoracic outlet syndrome and resultant excision of the first rib on the right. In rendering this opinion, Dr. Bennoch takes into consideration Ms. Johnson continues to suffer from intermittent numbness to her right arm.
Dr. Bennoch did not identify any preexisting disability attributable to the neck. In his deposition, Dr. Bennoch acknowledged that, prior to March 29, 2003, Ms. Johnson suffered prior episodes of neck pain and sought treatment for this neck pain. Dr. Bennoch, however, characterized this neck pain as transient pain, and not of a permanent nature. Further, Dr. Bennoch noted that, prior to March 29, 2003, Ms. Johnson had not suffered a herniated disc of the cervical spine; and, prior to March 29, 2003, Ms. Johnson had not been diagnosed with cervical radiculopathy.
Finally, Dr. Bennoch opines that the combination of her impairments creates "a substantially greater impairment than the total of each separate injury and/or illness and a loading factor should be added." Dr. Bennoch further opines that Ms. Johnson's existing disabilities, including the restrictions and limitations he imposed upon her, is going to make it quite difficult for her to find a job that she is qualified for and able to perform. Notably, in placing restrictions on Ms. Johnson Dr. Bennoch does not differentiate the restrictions applicable to the March 29, 2003 work-related injury from restrictions applicable to the preexisting disabilities.
Concluding that Ms. Johnson is permanently and totally disabled because of the combination of the injuries and disabilities suffered by her, Dr. Bennoch states,
She has significant disease of both the neck and the lower back along with decreased range of motion to both arms along with paresthesias and radiculopathy both to her arms and legs.
On cross-examination Dr. Bennoch acknowledged that he did not review all of Ms. Johnson's medical records predating the March 2003 injury. Notably, in this regard, he did not review the actual records of Dr. Hoeman. Rather, he reviewed Dr. Corsolini's summary of Dr. Hoeman's medical records. In this context, Dr. Bennoch did not know whether Ms. Johnson's neck was symptomatic before March 2003, but understood her preexisting condition included degenerative disk disease and she presented with occasional transient neck pain prior to March 29, 2003.
And, in light of Dr. Bennoch having not reviewed the actual medical records of Dr. Hoeman, Dr. Bennoch acknowledged on cross-examination that he was not aware that Ms.
Johnson had been diagnosed with depression prior to March 29, 2003 and was taking Paxil, an anti-depressant, in April 2002 for depression/anxiety. Rather, he relied on Ms. Johnson reporting a history of never having any problems with depression or anxiety before March 29, 2003. In light of this preexisting depression, Dr. Bennoch conceded on cross-examination that his assessment of permanent disability attributable to the depression should be separated or apportioned, and he apportioned the disability to reflect 5 percent disability preexisting the March 29, 2003 injury and 5 percent disability caused by the March 29, 2003 work-related injury.
In addition, in his deposition Dr. Bennoch offered initially his opinions under the assumption that, at the time of Ms. Johnson's injury on March 29, 2003, Ms. Johnson was working 40 hours per week. And on cross-examination Dr. Bennoch acknowledged that he did not know whether Ms. Johnson was working more or less than 20 hours a week at the time of the March 29, 2003 injury.
Further, on cross-examination Dr. Bennoch acknowledged that, prior to March 29, 2003, Ms. Johnson suffered from significant preexisting disability, including disabilities to her low back and right shoulder, which caused her to be governed by restrictions and limitations which rendered her sufficiently symptomatic to cause her to be on social security disability. And in this context Dr. Bennoch opines that Ms. Johnson is now permanently and totally disabled as a result of the combination effect attributable to the preexisting disabilities and the work-related injury of March 29, 2003.
Notably, in examining Dr. Bennoch's opinion of permanent total disability, the employer and insurer, and the Second Injury Fund, proffered certain questions, which resulted in Dr. Bennoch propounding the following testimony:
By Mr. Harmison [Employer/Insurer]
Q. Okay. If Ms. Johnson didn't have any preexisting problems and just had this particular situation you attribute to March of 2003, is it your opinion that she couldn't return back to work at Wal-Mart, but she perhaps could do other more sedentary things?
A. I think if you take just strictly her neck as the way it is now and her shoulders as they are now, she could not do a job on an eight-hour-a-day, several-days-aweek basis. So she can't do repetitive. Could she do something for a few hours? She probably could, but she'd probably pay for it. In other words, any kind of over activity with her neck now causes significantly increasing pain, and she's on a number of medications for that.
Q. She was on the medications before, though, correct?
A. Yes.
Q. In fact, I think we've established her preexisting condition was so symptomatic such that she was receiving social security disability?
A. Yes.
Q. Okay. And if I heard you right, your conclusion about permanent total disability is it's a combination effect?
A. Yes.
By Ms. Colburn [Second Injury Fund]
Q. But to reiterate, you believe that even if she did not have any of the preexisting problems, she could not hold down a job now because of the neck and shoulder problems that we have been discussing from March of 2003?
A. That is correct.
Phillip Eldred, who is a vocational expert secured by the employee, testified by deposition and in person at the evidentiary hearing held on June 11, 2008 (trial between the employee and Second Injury Fund). Mr. Eldred opined that, prior to March 29, 2003, Ms. Johnson presented with disabilities referable to her low back and right arm which caused her to be governed by restrictions and limitations, which rendered her eligible for receipt of social security disability compensation. Mr. Eldred further notes that among the multiple physical problems that qualified Ms. Johnson for social security disability compensation included "chronic myofasical neck pain." Considering the preexisting restrictions imposed by Dr. Moshen, which related to Ms. Johnson's low back and right upper extremity, Mr. Eldred opined that these restrictions were vocationally disabling such as to constitute a hindrance or obstacle to employment.
Further, based on these preexisting disabilities and applicable restrictions and limitations, and taking into consideration Ms. Johnson's employment history and educational background, Mr. Eldred opined that, prior to Ms. Johnson securing employment with Wal-Mart, she presented with a medical condition governed by restrictions and limitations that would support a basis for him concluding that she was permanently and totally disabled. And in this context, Mr. Eldred states that, while she was unemployable, she secured employment solely due to the benevolence of the employer, who offered accommodations to her, as well as accommodations to other individuals working as "people greeters", including a quadriplegic, who could not orally speak to (greet) customers but was given an electronic sign to greet customers. Mr. Edlred specifically noted that Ms. Johnson's employment with Wal-Mart was an "accommodated position" since she was only able to work 24 hours per week because of her existing disabilities.
Thomas Corsolini, M.D., who is a physician practicing in the specialty of physical medicine, testified by deposition in behalf of the employer and insurer. Dr. Corsolini performed an independent medical examination of Ms. Johnson on September 22, 2006. At the time of this examination, Dr. Corsolini took a history from Ms. Johnson, reviewed various medical records, and performed a physical examination of her. In light of his examination and evaluation of Ms. Johnson, Dr. Corsolini opined that, on March 29, 2003, while separating two shopping carts, Ms. Johnson sustained an injury in the nature of an aggravation of a preexisting impingement of the rotator cuff tendon in her left shoulder, which necessitated the eventual surgical repair of the left shoulder.
Dr. Corsolini, however, opines that Ms. Johnson does not need any additional medical care, relative to the accident and injury she sustained on March 29, 2003. Additionally, Dr. Corsolini opines that Ms. Johnson is at maximum medical improvement, and he is in agreement
with Dr. Mutchler in the disability suffered by Ms. Johnson relative to this injury, which he notes to be 9 percent to the upper extremity.
In addition, relative to the cervical spine, Dr. Corsolini opined that the March 29, 2003 incident did not cause Ms. Johnson to sustain any injury to her cervical spine. Rather, Dr. Corsolini notes Ms. Johnson suffered from neck pain prior to the accident, which he attributed to the degenerative process consisting of a bone spur formation causing spinal stenosis.
On cross-examination Dr. Corsolini acknowledged that in 1998 Ms. Johnson saw John Ferguson, M.D., who is a neurosurgeon, for neck pain; and Dr. Ferguson did not identify the condition to merit consideration for surgery. (In rendering this opinion Dr. Corsolini noted that he did not review the medical records of Dr. Ferguson, but rather relied on his review of other medical records, including the medical records of Dr. Hoeman.)
Also, on cross-examination, Dr. Corsolini acknowledged that, in light of the history provided to Dr. Osborn by Ms. Johnson, it was "possible" that Ms. Johnson provided a history consistent with cervical radiculopathy. Similarly, Dr. Corsolini acknowledged that Ms. Johnson made reports to her medical providers consistent with the diagnosis made by Dr. Strang. And Dr. Corsolini acknowledged that he did not have the records from the physical therapy clinic Health South, which were consistent with the history provided by Ms. Johnson to other providers. In this context, and relative to the diagnosis and treatment provided by Dr. Mutchler, Dr. Corsolini acknowledged that it can be difficult to distinguish the source of pain between the neck and the shoulder insofar as the "territories of pain overlap greatly, and it's not always to know for sure which one might be the source."
At the hearing of August 18, 2009, Ms. Johnson testified that she continues to experience considerable discomfort and pain. She notes that she suffers from a restriction of motion, due both to pain and somewhat due to the fusion itself. Additionally, she notes that the neck pain causes her to have headaches approximately every day. In regards to her left arm, Ms. Johnson does not believe that she has much strength in her left arm and she tends to drop things when she holds them in her left hand. She avoids using her left (nondominant) hand due to weakness. She has difficulty reaching overhead with her arms. She has difficulty sleeping because of discomfort from her neck, left shoulder, and low back.
Further, Ms. Johnson testified that, following the shoulder surgery, and with accommodations made by the employer, she returned to work. However, following the neck surgery, she had moved to Springfield and was unable to secure employment with such accommodations. Since the neck surgery, Ms. Johnson has not returned to any employment.
