Claim of Pezzolanti v. Green Bus Lines, Inc.
The claimant, a mechanic, suffered a left wrist injury in October 1980 when a loose steering wheel struck his wrist after hitting a pothole. This incident revealed a pre-existing, asymptomatic giant cell tumor in his left radius. Following a biopsy and surgical removal of the tumor on January 8, 1981, the claimant continued to experience pain and disability, necessitating a second surgery in 1982. The self-insured employer challenged the Workers' Compensation Board's decision, arguing against a continued causally related disability beyond the initial surgery date, asserting that the accident did not aggravate the tumor. However, the Board affirmed its decision, supported by medical testimony that while the trauma did not cause or aggravate the tumor itself, it acted upon the pre-existing condition to cause a new, occupationally disabling pain and disability that extended beyond the tumor's surgical removal.
