An adjustable immobilizing joint brace has a pair of opposed, spaced apart first supports for supporting and immobilizing a joint. Each first support has a pair of first joint holes proximate a first end. One of the holes of the pair of first joint holes is spaced further from the first end of the first support than the other hole. A pair of opposed, spaced apart second supports has two opposed sides. Each second support has a pair of second joint holes proximate a joint end. The pair of second joint holes can be aligned with and attached to the pair of first joint holes on either side of the first support to form different angles of attachment between the first supports and the second supports depending on the orientation of the first supports relative to the orientation of the second supports.
