Claimant: Claimant worked for Employer as a member of a floor crew. The floor crew duties included buffing, cleaning and waxing floors. Claimant was a full-time employee on the night shift. On March 18, 2003, Claimant was buffing a floor when the handle on his buffer broke. Claimant notified his manager, and the manager used tape to try to repair the buffer. When Claimant resumed buffing, the tape came off exposing a wire, the wire sparked, causing an electrical shock, and knocked his left hand off the buffer. The top of his hand hit a wall, and he burned the volar side of his left hand.
Claimant notified his manager, and ice was placed on his left hand. Injury papers were completed, and although Claimant didn't return to his work, he stayed until the end of his shift. When his shift ended, Claimant went to the emergency room of a local hospital because his hand remained swollen.
At the hospital, Claimant told the emergency room staff he had been electrocuted at work. An x-ray of his left hand was obtained, and he was told he had a dislocated bone in his hand. A specialist was consulted, and Claimant was told he might need hand surgery. He agreed to undergo left hand surgery.
Following surgery, Claimant was in a cast for approximately three months. He didn't return to work with Employer because he was terminated two or three weeks following his hospital stay. Claimant couldn't work while the cast was on. Employer denied his claim for benefits. His medical bills have not been paid, and Claimant did not have private health insurance.
At the date of the hearing, Claimant testified he feels fine, and only notices pain when his hand is exposed to cold weather or if he lifts a heavy item. Claimant has started his own janitorial company and is actively working. Claimant's scarring was viewed, demonstrating surgical scars present on the dorsum of his hand, and palm discoloration of approximately two inches long, and of varying widths. No visible scarring was present on his left index finger.
Upon cross-examination by Employer, Claimant verified he has no recollection of his hand hitting anything after the buffer sparked. He testified sparks did land on his hand, although he can't say exactly where the sparks landed. Claimant acknowledged he told Dr. Tung his hand could have hit something. Claimant testified he didn't tell Dr. Schlafly he hit his hand, and he doesn't remember seeing Dr. Ollinger. Claimant denied he had ever received treatment for his left hand prior to this injury. Claimant verified he was injured on the fifth day of his employment, and was terminated on March 27, 2003, due to the discovery of a previous felony conviction that he had not reported on his application for employment.
Barnes-Jewish Hospital: Claimant was seen in the emergency room (ER) on March 19, 2003. His chief complaint was swelling of his left hand, and a bump on the top of his hand with dorsal numbness after an electrical shock. An x-ray was obtained that demonstrated a healed $4^{\text {th }}$ metacarpal fracture, left index finger soft tissue swelling with an osseous abnormality. The ER physician noted Claimant had experienced a powerful shock that flung his left hand back, and the physician noted a small volar blister on Claimant's left index finger. The ER intake drawing indicated two blisters on the volar side of Claimant's left index finger at the $1^{\text {st }} proximal joint, and at the 2^{\text {nd }}$ proximal joint. No other blister sites are identified on the intake drawing. Claimant's CPK enzyme level was mildly elevated, and Claimant was admitted for observation and definitive therapy for a boxer's fracture.
On March 21, 2003, Dr. Tung took Claimant to surgery and performed a corrective osteotomy and plate fixation of Claimant's left $4^{\text {th }}$ metacarpal neck fracture. Dr. Tung noted Claimant's left hand fracture by history appeared to be a new injury, but Claimant's physical exam and x-rays supported a mal-union of a previous fracture. Claimant was discharged the day of surgery. Dr. Tung's last progress note dated June 16, 2003, indicated Claimant had full mobility of his left hand and left ring finger. Claimant complained of tenderness with heavy activity and cold weather. Dr. Tung planned to re-evaluate Claimant in three to four months for a final check.
