Claimant sustained compensable totally disabling accidental injuries on January 20, 1947, consisting of an intertrochanteric fracture of the right femur. The medical evidence is to the effect that a major surgical operation, described as a subtrochanteric osteotomy, would probably somewhat reduce claimant's disability although a "large degree of disability" would continue. The issue tendered is whether the board's finding that claimant's refusal to undergo the operation is not unreasonable, has evidentiary support ( Matter of Palloni v. Brooklyn-Manhattan Tr. Corp., 215 App. Div. 634; Matter of Peasley v. Wendling Iron Works, 277 App. Div. 821, motion for reargument granted 277 App. Div. 953, on reargument 277 App. Div. 622). Claimant is past sixty-six years of age and has for many years, and long prior to his accidental injuries, suffered from chronic arthritis in many joints of his body, including his pelvis region. His age, his history as to this affliction, and the evidence as to the nature and risks of the operation which has been medically advised and the uncertainty of its outcome all are such as to amply sustain the findings of the board. Decision and award affirmed, with costs to the Workmen's Compensation Board. Foster, P.J., Brewster, Bergan and Halpern, JJ., concur.
