In November 1999, claimant injured her low back as a result of slipping on a wet, soapy floor. Initially, Claimant was diagnosed with a concussion, cervical strain and low back strain. Claimant treated through September 2000.
Dr. Raskas, noted, by x-ray and CT scan that Claimant had a functional L6 vertebrae (congenital anomaly) together with a diagnosis of isthmic or degenerative spondylolithesis at L5-6. He also noted narrowing at L6-S1 with significant bone overgrowth and sclerotic changes about the L5 and L6 facet joints.
Claimant underwent steroid injection therapy and returned to work with medical restriction against lifting greater than 25 pounds on a regular basis, a 50 pound maximum lift and restriction against repetitive bending or twisting at the waist. Moreover, she needed to be able to sit and stand as needed.
Claimant entered a WC settlement in 2001 of twelve and one-half percent PPD of the body referable to the low back. She received nothing for her concussion.
Dr. Adam Sky, a psychiatrist, assigned a twenty-five percent pre-existing PPD of the body referable to depression.
Claimant's expert, Dr. David Volarich, examined Claimant and correlated her course of disabling symptoms with the surgical record and pain management. He diagnosed failed back syndrome. He assigned an overall seventy percent PPD of the body referable to the low back referable to the reported injury.
Ultimately, he concluded Claimant was permanently and totally disabled as a result of the combination of the pre-existing low back condition and the current low back injury together with her treated condition of depression, also pre-existing.
Claimant's testimony was very credible and unrebutted.
Claimant's vocational expert, Ms Sherry Browning, examined Claimant, administered various tests and measures, reviewed her work history, and reviewed the medical records. She concluded Claimant was no longer employable in the open labor market.
The SIF offered no evidence.
