Claim:
A hand orthosis for maintaining separation between a patient's thumb, fingers, and palm, said hand orthosis comprising: an elongated body having an upper end and a lower end; a middle finger concavity formed in said elongated body, said middle finger concavity originating at a first point on said and terminating at a second point on said elongated body, said second point being lower on said elongated body than said first point; a ring finger concavity formed in said elongated body, said ring finger concavity substantially parallel to said middle finger concavity, said ring finger concavity separated from said middle finger concavity by a first ridge; a little finger concavity formed in said elongated body, said little finger concavity substantially parallel to said ring finger concavity, said little finger concavity separated from said ring finger concavity by a second ridge; an index finger concavity formed in said elongated body, said index finger concavity bounded along one side and separated from said middle finger concavity by a third ridge, said index finger concavity bounded along an opposite side by a fourth ridge, said index finger concavity having an original end and a terminal end, said terminal end being closer to said upper end of said elongated body than said original end; and a thumb concavity formed in said elongated body, said thumb concavity having an original end proximate to said middle finger concavity and a terminal end proximate said elongated body upper end, said thumb concavity terminal end directed toward said index finger concavity terminal end, said thumb concavity terminal end and said fourth ridge proximate to said index finger concavity terminal end being substantially equidistant from said upper end, said thumb concavity terminal end separated from said index finger concavity terminal end by a fifth ridge.
