Abstract: A splint for treatment of a joint including a generally longitudinal body including first and second portions forming inner and outer splint layers, with the second portion being rollable onto the first portion to form the splint. The outer splint layer may include a longitudinal cavity for insertion of a stay, and/or may include a fluted section for permitting insertion of a stay between the inner and outer splint layers. The longitudinal body may be linear or curved. The first and second portions may include areas having different thicknesses for adding rigidity to the splint structure at a predetermined location. The splint may include a cutout for exposing a predetermined portion of a user's finger. The splint may be made of a flexible material such as rubber, silicone and/or urethane. The splint may include a reduced friction surface layer for minimizing sticking of the splint during donning.
