for treatment on July 26, 2006, and reported that her problems were continuing, with increased pain in the right leg. Dr. Cabot Sweeney ordered an MRI, which was subsequently obtained on July 31, 2006, and which revealed a diffuse bulging annulus at L3-L4 contacting the right L3 nerve root.
Employer eventually authorized treatment with Dr. James Zarr, who evaluated employee on September 19, 2006, and noted that the July 2006 MRI findings at L3-L4 were new. Dr. Zarr opined that the July 2006 work injury was the cause of employee's current symptoms and recommended lumbar epidural injections. Employee underwent a series of injections which provided temporary relief from her low back pain. On December 13, 2006, Dr. Zarr evaluated employee and found that her pain had completely resolved following the injections. Dr. Zarr released employee from his care and opined that employee suffered 0% permanent partial disability as a result of the July 2006 work injury.
After Dr. Zarr released employee from treatment, she suffered a recurrence of severe pain in her low back and underwent treatment at the St. Joseph Pain Clinic in 2007 and 2008 including lumbar injections to address pain referable to the L3-L4 nerve root. On July 8, 2008, Dr. Vincent Johnson indicated he would recommend a consultation with a surgeon if employee's pain continued. Employee continued to experience pain and ultimately underwent a lumbar laminotomy and foraminotomy with decompression of the L3-L4 nerve on the right.
Employee's low back pain improved after the surgery, but employee still suffers pain after activity such as housecleaning. Employee doesn't take as much pain medication as she did before the surgery, and she is able to sleep through the night. Employee limits her stooping, bending, and reaching, and tries not to carry more than 20 pounds. Employee settled a Kansas workers' compensation case against the employer on January 23, 2012, for a lump sum of $73,930.00 based on disability under Kansas law, plus a Medicare Set-Aside Agreement to cover employee's future medical expenses.
Dr. Swaim opined that employee's occupational injury of July 18, 2006, was the prevailing factor causing employee to suffer an injury to the L3-L4 disc, which he rated at 25% permanent partial disability of the body as a whole. Dr. Swaim opined that employee's preexisting disabling conditions combined synergistically with the injury of July 18, 2006, to the extent of creating an additional 10% permanent partial disability of the body as a whole. We find persuasive Dr. Swaim's opinion (and so find) that employee suffered permanent partial disability as a result of the July 18, 2006, incident. We find that employee suffered a 7.5% permanent partial disability of the body as a whole referable to the lumbar spine as a result of the primary injury.
