October 4, 1999. At the time of discharge, he was again instructed to keep his left leg elevated with no prolonged standing or excessive ambulation.
Following employee's January 15, 2001, primary injury and subsequent recovery, a May 7, 2001, functional capacity evaluation determined employee to be employable at a heavy workload demand level. Employee went back to work for employer in May 2001. Employee returned to work at his previous job for 4½ years until December 2005. The only assistance employee required in performing his job during this time was lifting 100 lb. doors on a locomotive. He required this assistance due to back complaints, but not the result of any residual disability with his left leg.
On January 26, 2005, employee sustained a lower back injury at work while lifting. On February 26, 2005, employee sustained an injury to his left ankle. In May 2005, employee developed left wrist discomfort, which necessitated conservative care and diagnostic evaluation. In October 2005, employee was hospitalized at Ste. Genevieve Memorial Hospital for 4-5 days for lymphedema and cellulitis of the lower left leg and was treated with antibiotics.
Employee did not notify employer as to why he was hospitalized in October 2005, nor did employee ever request additional medical care for his left leg from employer after May 1, 2001. Employee went back to work following the October 2005 hospitalization, but was only able to work for a week or two due to left leg swelling. Employee officially quit his job in December 2005.
Dr. Tate opined that employee reached maximum medical improvement on September 3, 2001. She further opined that as a result of the primary injury employee sustained 7% permanent partial disability to his left calf. Dr. Tate did not attribute any other permanent disability to the primary injury. Further, she testified that employee would be able to sustain employment. However, she also stated that due to his bilateral venous stasis, lymphedema, and cellulitis, standing might be difficult and he would be restricted to a sedentary job with a limited amount of walking or standing up to one hour at a time for a total of three hours a day.
Dr. Cadiz noted in his August 9, 2002, report that employee had a preexisting condition of venous insufficiency, bilaterally, and that the January 2001 incident was a soft tissue acute injury, superimposed upon a chronic condition. Dr. Cadiz stated in his September 5, 2002, report that the acute injury from the January 2001 accident had resolved.
Dr. Poetz provided three separate independent medical evaluation reports, one in 2004, 2007, and 2010. In 2004, Dr. Poetz opined that as a result of the primary injury employee sustained 60% permanent partial disability to the left lower extremity at the knee, 25% permanent partial disability of the body as a whole for the rib injury, and 30% permanent partial disability of the body as a whole referable to the lumbar spine injury. With respect to employee's preexisting disabilities, Dr. Poetz opined that employee suffered from 10% permanent partial disability of the left leg for phlebitis, 10% permanent partial disability of the left leg for cellulitis, 25% permanent partial disability of the left wrist, 10% permanent partial disability of the body as a whole for astigmatism.
