Abstract: A bowler's finger sleeve (10) is constructed of a high density neoprene sheet to form a curved tube which is placed on a bowler's finger (12) to aid the bowler in controlling a bowling ball (16). The sleeve is constructed using a method employed to construct a prior art orthopedic splint. An internal ridge (52) of the sleeve is placed at a dorsal surface (56) of the bowler's finger.

Abstract: An orthopedic splint (10) comprises a neoprene rubber tube having an internal surface forming a curved splint passage (50) for snugly fitting on a joint (14, 16) to be treated and defining a radially directed internal ridge (52) extending lengthwise along the tube for pressing against the joint. The splint is constructed by folding in half a flat sheet of neoprene rubber (18), attaching free end portions (26, 28) of the sheet to form a transition tube (44) having a transition internal passasge (46), sewing a seam (40) in said free adjacent free edge portions to define a wedge shaped angle pointing away from the transition internal passage having an angle of between 140.degree.-160.degree., cutting away excess neoprene sheet so as to leave a V-shaped seam allowance (42) at the free edge portions beyond the seam to form the ridge, and turning the transition tube inside out to form the splint (10).
